Description
[0001] This application is a U.S. National Phase under 35 USC 371
of PCT Application No. PCT/ES2009/070603 filed Dec. 17, 2009, the
disclosure of which is incorporated by reference herein.
[0002] Vacuum, pressure or liquid pump, of the type that comprises
driving means with a shaft connected to an eccentric, at least two
membranes that block a similar number of apertures in a box,
characterised in that it comprises: a connecting rod, in whose
centre houses a single bearing for each eccentric through which the
referred shaft passes and at least two actuators that join the
membranes to the connecting rod, being said actuators articulating
with the connecting rod.
BACKGROUND OF THE INVENTION
[0003] The use of pumps is known in the state of the art, with one
or two heads, one on each side of the motor, or even two on the
same side (opposite with traditional connecting rods and a similar
number of bearings). If more extraction capacity is required
additional, heads can be added, or they can be over-dimensioned,
which involves the use of as many connecting rods, bearings and
membranes as required heads, increasing sizes and motor powers.
[0004] Thus, Spanish utility model 0244030 "A DEPRESSION OR VACUUM
MEMBRANE PUMP" is known from 1979, in the name of PIERBURG BMBH
& CO.KG, which refers to a depression or vacuum membrane pump,
especially for conditioning automobile elements, such as servo
brakes, the membrane of which is operated from a main shaft via a
connecting rod and the chamber that is next to the head is sealed
against the atmosphere, the chamber is connecting with the
atmosphere by means of at least one valve that allows access the
air and prevents the air exit from chamber to the atmosphere. In a
similar fashion another valve performs the same process to expulse
the air.
[0005] It is known in the state of the art the document FR2049347,
in the name of Albert Cozic, that refers to bilge pump for a boat
or vessel of any type is provided which is operative in response to
any movement of the boat in which the pump is provided, such as
pitching or rolling. The pump includes preferably two or three
diaphragm-type pumps mounted in a housing. A vertical shaft is
rotatably mounted in a housing, the shaft is secured to an
unbalanced mass exterior responsive to the movements of the boat to
effect the rotation of the shaft. The end of the shaft remote from
the end at which the mass is secured comprises an eccentric journal
which is connected to a two- or three-arm member by a bearing and
whose arms are in turn connected to the diaphragms for operating
same successively to take in bilge water through intake pipes and
valves and discharge same through outlet valves and pipes.
[0006] The driving means of pump are an unbalanced mass and do not
comprise any motor. The movements of the mass depend on movements
of the sea, which are variable by its nature. Actually, this
document forms part of the prior art in respect to bilge pumps for
a boat or vessel which are operative only in the sea.
DISCLOSURE OF THE INVENTION
[0007] This application is framed within the sector of vacuum,
pressure and liquid pumps.
[0008] With this invention, the inventor intends to operate with a
single connecting rod, more heads, in other words, using a single
connecting rod, be able to place as many actuators with membranes
as permitted the connecting rod size, so that, to larger size of
the connecting rod, greater number of actuators can be operate.
This results in economic savings for both the manufacturer and the
end buyer.
[0009] This means that the need for independent regulation of force
centring and work loads is eliminated. Currently, each head
incorporated into the pump requires a different load point along
the shaft for each one. This invention uses a single bearing for
each eccentric on which point all forces are balanced and
stabilised. This is because only one connecting rod is required
independently of the number of heads.
[0010] Thus, greater performances are obtained with less space
because a smaller pump can provide identical or even better results
than larger pumps. Similarly, this means that this smaller size
leads to significant space and weight savings.
[0011] In this way, the present pump can operate a determined
number of membranes with the same connecting rod and all forces
caused by the heads and membranes are centred with respect to each
other at the same working point. When an expulsion force is
generated, another intake force is produced at the opposite point,
with these being equal at all cycle points.
[0012] One objective of this invention is a vacuum, pressure or
liquid pump, of the type comprising driving means with a shaft
connected to an eccentric, at least two membranes that block a
similar number of apertures in a box, characterised in that it
comprises: a connecting rod, the centre of which houses a single
bearing for each eccentric through which the referred shaft passes
and at least two actuators that join the membranes to the
connecting rod, with said actuators articulating with the
connecting rod.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] In order to facilitate the description, this report is
accompanied by four sheets of drawings that represent a practical
exemplary embodiment, which is given as an example that does not
limit the scope of this invention.
[0014] FIG. 1 is a general view of the invention, in which the
membranes and heads have been eliminated.
[0015] FIG. 2 is a close-up without the box, membranes and
heads.
[0016] FIG. 3 is a close-up of an actuator, a part that is
connected by means of a hinge joint to the connecting rod.
[0017] FIG. 4 is a side view of the invention applied to an end
product.
SPECIFIC EXEMPLARY EMBODIMENT OF THIS INVENTION
[0018] Thus, FIG. 1 illustrates a box 1, driving means or motor 2,
apertures in the box 4, which houses the membranes and heads, a
shaft 5, an eccentric 8, a connecting rod 6, actuators 7 and the
connecting rod pass-through orifices 10 (at the actuator 7
positions).
[0019] FIG. 2 shows driving means 2, connecting rod 6, eccentric 8,
shaft 5, connecting rod pass-through orifices 10 and actuators
7.
[0020] FIG. 3 illustrates the actuator 7 that is joined to the
connecting rod via the actuator pass-through orifice 11, with a pin
to form a hinge joint.
[0021] Lastly, FIG. 4 represents box 1, heads 3, box apertures 4,
connecting rod 6, actuators 7, shaft 5, connecting rod pass-through
orifices 10, pins 12 that form hinges joints and a bearing 9
housing the eccentric.
[0022] Thus, in a specific exemplary embodiment, the product is
basically configured as follows: it comprises a box 1, driving
means 2, with shaft 5 connected to eccentric 8, two membranes (as
many as necessary, three, four, six, despite the fact that,
although there are two in this embodiment, they cannot be seen
because they are housed inside), which block the orifices in box 4
of cited box 1.
[0023] Regarding actuators 7 and the membranes, it is possible to
configure as many as desired, starting with two by taking into
account the positions of actuators 7 so that they compensate the
forces as well as possible. For example, with three actuators 7,
each one could be positioned at 120.degree., which would then
largely balance the forces. Five actuators would be positioned
every 72.degree. and so on according to the desired number. The
idea is to divide the circumference by the desired number of
actuators 7.
[0024] Unlike known pumps, this invention includes a single bearing
9 for each eccentric 8.
[0025] It also comprises connecting rod 6, the centre of which
houses a single bearing 9, through which the referred shaft 5
passes and at least two actuators 7 that connect the membranes
housed inside heads 3 to connecting rod 6, with said actuators 7
articulating with connecting rod 6 by, for example, pins.
[0026] When motor 2 is switched on, it turns shaft 5 which, by
means of eccentric 8 produces a similar movement of connecting rod
6.
[0027] Actuators 7 are articulated to connecting rod 6 by joints
that employ pins 12 in this embodiment to form hinge joints.
[0028] Moreover, in this invention the connecting rods 6 partially
house actuators 7 just as shown in FIGS. 1, 3 and 4. In this
embodiment, connecting rod 6 articulates by means of a first
pass-through orifice 10 through which actuator 7 passes, facing it
via pin 12 (FIG. 4), which passes through actuator 7, leaving both
pass-through orifices 10 and 11 aligned (FIGS. 1, 2 and 4).
[0029] This enables actuators 7 to continue pushing the membranes
housed inside head 3 so that they continue to block and unblock the
respective entrances and exits inside head 3. Even when the
eccentric movement is produced, the connecting rod forces that the
movement on the membrane is linear because actuator 7 articulation
on connecting rod 6 allows any membranes position to be recovered
while these maintain their respective positions over apertures
4.
[0030] In fact, connecting rod 6 becomes the connection between
actuator 7 and bearing 9 and eccentric 8, thus permitting the
membranes to work and adapt to any position as forced by the
eccentric.
[0031] This invention patent describes a new vacuum, pressure or
liquid pump. The exemplary embodiments descried here do not limit
this invention, which can have various applications and/or
adaptations within the scope of the following claims.
