Description
BACKGROUND OF THE INVENTION
[0001] I. Field of the Invention
[0002] This invention relates generally to a gas decompression
magazine and, more specifically, to a gas decompression magazine of
a toy gun that applies high pressure gas as power source, a
decompression valve and a decompression chamber are between the
high pressure gas bottle and the control valve to apply the cover
of the decompression valve to adjust the resilience of the pressure
spring and control the pressure of high pressure gas after
decompression, such that to assure the shooting force is within
safety regulation.
[0003] II. Description of the Prior Art
[0004] Heretofore, it is known that the structure of the gas bottle
powered toy guns are not available for game for their lethality,
those toy guns need decompression valve connected to the high
pressure gas bottle to lower the pressure of the gas bottle, that
can increase shooting quantity with the same capacity of gas bottle
and assure shooting force is within safety regulation.
[0005] However, referring to FIG. 5 and FIG. 6, the cross-sectional
view of the whole body and the fixed pressure valve (the
decompression valve of the present invention) of Taiwan listed
pattern no. 568627 "Gas Decompression Device of Toy Guns". The
structure of the fixed pressure valve of the prior art is to have a
bullet guiding slot 11 and a container 12 installed in parallel
with the magazine 10, a decompression valve 20 is inside the
container 12 to subdivide the container 12 into a gas bottle
chamber 12a and a decompression chamber 12b, a control valve 30 is
installed above the magazine 10, a high pressure gas bottle 40 is
inside the gas bottle chamber 12a, the high pressure gas bottle 40
connects to the decompression valve 20; the working principle is
when the high pressure gas inside the high pressure gas bottle 40
enters the decompression chamber 12b, the two sides 221, 222 of the
plunger 22 inside the decompression valve 20 apply the inverse
proportion of area verse pressure physical character to have the
pressure equilibrium between both sides of the plunger 22 of the
decompression valve 20, the area on the decompression valve 12b of
the plunger 22 has the larger area to have less pressure for less
gas pressure to achieve decompression purpose. The defects of above
structure is the known decompression valve a is immobile, the
decompression effect is fixed; while application or testing, users
find the gas pressure is too high or too low, the known prior art
with fixed plunger 22 can not change or adjust the gas pressure
entering the decompression chamber 12b.
SUMMARY OF THE INVENTION
[0006] It is therefore a primary object of the invention to provide
a gas decompression magazine of a toy gun that applies the
decompression valve to adjust the gas pressure to make sure the
high pressure gas inside the decompression chamber is in the best
application range.
[0007] In order to achieve the objective set forth, a gas
decompression magazine of a toy gun in accordance with the present
invention comprises a bullet guiding slot and a container installed
in parallel inside the magazine, a decompression valve is inside
the container and subdivides the container into a gas bottle
chamber and a decompression chamber, a control valve is on the top
of the magazine, a gas bottle is installed inside the gas bottle
chamber and connects to the decompression valve; the major
character is: a plunger and a compression spring are installed in
series inside the valve body of the decompression valve, then are
threaded sealed by a cover on the top of the valve body; a bottle
connector is on the bottom of the valve body; a small hole is on
the wall of the valve body to interconnect the space above the
bottle connector and the decompression chamber; the bottle
connector connects to the high pressure gas bottle on the lower
portion and pierces the high pressure gas bottle while connecting
to release the high pressure gas; a top needle is on top of the gas
outlet on the center of the bottle connector, then a threaded cover
seals the top and has the top needle pass through the threaded
cover and prop the plunger.
[0008] While application based on above structure, users can adjust
the depth of the cover inside the valve body to change the distance
between the bottom of the cover and the top of the plunger, the
decompression strength of the compression spring in between
changes, the shooting gas pressure after adjustment can meet the
safety requirement.

[0014] FIG. 5 is a cross-sectional view of the prior art;
[0015] FIG. 6 is a cross-sectional view of a further embodiment of
the prior art.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Referring to FIG. 1 to FIG. 3 and FIG. 5, the parts with the
same number tags are the same or similar parts with the prior
art.
[0017] The present invention comprises a bullet guiding slot 11 and
a container 12 installed in parallel inside the magazine 10, a
decompression valve 20 is inside the container 12 and subdivides
the container 12 into a gas bottle chamber 12a and a decompression
chamber 12b, a control valve 30 is on the top of the magazine 10, a
gas bottle 40 is installed inside the gas bottle chamber 12a and
connects to the decompression valve 20.
[0018] The major character is: a plunger 22 and a compression
spring 23 are installed in series inside the valve body 21 of the
decompression valve 20, then are threaded sealed by a cover 24 on
the top of the valve body 21, a bottle connector 25 is on the
bottom of the valve body 21; a small hole 211 is on the wall of the
valve body 21 to interconnect the space above the bottle connector
25 and the decompression chamber 12b; the bottle connector 25
connects to the high pressure gas bottle 40 on the lower portion
and pierces the high pressure gas bottle 40 while connecting to
release the high pressure gas; a top needle 252 is on top of the
gas outlet 251 on the center of the bottle connector 25, then a
threaded cover 253 seals the top and has the top needle 252 pass
through the threaded cover 253 and prop the plunger 22.
[0019] While in real application based on the structure described
above, the gas pressure from the gas bottle 40 can lift the top
needle 252, the cap 2521 of the top needle 252 blocks the bottom of
the threaded cover 253 to prevent the high pressure gas from
entering the decompression chamber 12b (as shown in FIG. 3); when
the pressure from the compression spring 23 above the plunger 22 is
larger than the strength from the gas pressure from the gas bottle
40 to the cap 2521 of the top needle 252 and the bottom of the
plunger 22 (such as instant release of the gas pressure inside the
decompression chamber 12b), the compression spring 23 pushes and
opens the top needle 252 through the plunger 22 (as shown in FIG.
4), the high pressure gas from the gas bottle 40 flows into the
valve body 21 again and also flows into the decompression chamber
12b through the small hole 211 on the wall of the valve body 21,
until the strength under the bottom of the plunger 22 is larger
than the compression spring 23 on top of the plunger 22, the cap
2521 of the top needle 252 seals the washer 254 under the threaded
cover 253 to close the gas outlet 251, such can close the valve
automatically and reduce the gas pressure.
[0020] While in real application based on the structure described
above, users can adjust the depth of the cover 24 inside the valve
body 21 to change the distance between the bottom of the cover 24
and the top of the plunger 22, the decompression strength of the
compression spring 23 in between changes, the shooting gas pressure
after adjustment can meet the safety requirement.
[0021] While a preferred embodiment of the invention has been shown
and described in detail, it will be readily understood and
appreciated that numerous omissions, changes and additions may be
made without departing from the spirit and scope of the
invention.
