The accommodation chamber is configured to receive a high-pressure gas cylinder. A stabbing portion is located above the accommodation chamber, and a first conduit is defined in the body beside the stabbing portion. The pressure valve is fixed in the body above the accommodation chamber. An axis of the pressure valve is intersected with an axis of the high-pressure gas cylinder. The body further includes an air guide room defined on the pressure valve. The control valve is located beside the air guide room and is connected with an air discharge chamber, a discharging ring and a nozzle of the gas cylinder magazine. The control valve guides the high-pressure gas to the discharging ring via the air discharge chamber so that a BB bullet is shot from the nozzle.
Description
- The present invention relates to a gas cylinder magazine which has a pressure valve of a small size and is capable of adjusting a pressure.
- A conventional air-pressure BB gun contains a magazine for receiving BB bullets. The magazine also contains a vaporizing space which is filled with liquid gas to generate air pressure. After the gas valve is started, the gas in the vaporizing space is released upward, and the BB bullets are pushed to a nozzle so as to be shot via a barrel.
- Because the liquid gas is filled in the conventional magazine, pollution will occur. To overcome such a problem, a gas cylinder magazine is applied to replace the conventional magazine so that CO2 of the high-pressure cylinder is released to shoot the BB bullets by using a gas pressure.
- A magazine of a high-pressure cylinder is disclosed in U.S. Pat. No. 7,237,543 and contains a
body 50, and thebody 50 includes an accommodation chamber 501 configured to receive a high-pressure cylinder 40, a pressure reducing valve 51 is accommodated in thebody 50 above the accommodation chamber 501, and a piercing element 511 is accommodated in thebody 50 facing the accommodation chamber 501, such that after the high-pressure cylinder 40 is forced into the accommodation chamber 501 to pierce anopen end 41 of the high-pressure cylinder 40, and the high-pressure gas is released to flow through an conduit of the piercing element 511. The accommodation chamber 501 has a cap 54 covered on an opening of a bottom thereof, and the pressure reducing valve 51 has a separator 52 and a piston 521 moving between the separator 52 and the pressure reducing valve 51, wherein an air channel is defined in a center of the piston 521 and communicates with the high-pressure cylinder, such that the piercing element 511 pierces the high-pressure cylinder 40 to release the gas to flow into asecond air chamber 502 of the pressure reducing valve 51 relative to the piston 521, wherein thesecond air chamber 502 of the separator 52 has two orifices 523 defined above the piston 521, and a press spring 522 is received in thesecond air chamber 502 of the separator 52 and the piston 521 so that the piston 521 is pushed by the press spring 522 to move to thesecond air chamber 502 and is pressed by the gas of the high-pressure cylinder 40 to pass through the air channel of the piston 521, wherein the gas accumulates in thesecond air chamber 502 and the piston 521 to produce an internal pressure, and the internal pressure is discharged out of the two orifices 523 upward. - The
body 50 further includes afirst air chamber 503 defined above the separator 52, and the pressure accumulates in thefirst air chamber 503 after the internal pressure is discharged out of the two orifices 523 upward. When the pressure increases to a predetermined pressure value, the press spring 522 of thesecond air chamber 502 urges the piston 521 to balance the pressure from the high-pressure cylinder 40 via the piercing element 511, and the piston 521 stop the conduit of the piercing element 511 to produce airtightness and to stop the pressure increasing from the high-pressure cylinder 40, hence the pressure of thefirst air chamber 503 maintains at the predetermined pressure value. - The
first air chamber 503 of thebody 50 communicates with thecontrol valve 30 via a passing orifice, wherein thecontrol valve 30 is communicated when thebody 50 is accommodated in the handle of a BB gun, and the gas flows through the top of thebody 50 to push the BB bullets to shoot via the barrel. - However, the magazine of the high-pressure cylinder of U.S. Pat. No. 7,237,543 has following defects:
-
- 1) The piston 521 and the press spring 522 are accommodated in the
second air chamber 502 longitudinally and contact with a stop end of the piercing element 511, so when the gas flowing through the piercing element 511 from the high-pressure cylinder 40 is balanced with the pressure between thesecond air chamber 502 and thefirst air chamber 503, the pressure of the high-pressure cylinder 40 has to deduct an elasticity value of the press spring 522, thus causing imbalance of a top and a bottom of the piston 521. The downward elasticity of the press spring 522 offsets a release value of the pressure of the high-pressure cylinder 40, and after the high-pressure cylinder 40 releases the pressure repeatedly, the press spring 522 moves downward to release the pressure from the high-pressure cylinder 40 early. But the pressure is released from the high-pressure cylinder 40 greatly, so the stop end of the piercing element 511 and the piston 521 cannot be connected tightly, thus losing the gas and having insufficient pressure when shooting the BB bullets. - 2) The piston 521 and the press spring 522 of the
second air chamber 502 contacts with the stop end of the piercing element 511 longitudinally, so the internal space of themagazine 50 is occupied largely, and a length of thebody 50 has to be increased to mate with a size of the piston 521 and the press spring 522, thus having an increased size and fabrication cost.
- 1) The piston 521 and the press spring 522 are accommodated in the

-
- 1) The axis of the pressure valve V is intersected with the axis of the high-
pressure gas cylinder 40 so that the pressure valve V moves horizontally, and the high-pressure gas of the air gun is not pushed by the spring and the valve to control the pressure of the air gun accurately. Preferably, the elasticity of thesecond spring 21 is more than the elasticity of thefirst spring 25 so that the switching of the air inflation and airtightness produce exactly and quickly, thus shooting the BB bullet from the air gun at a high speed. - 2) When inflating the gas to the air gun in various areas, temperatures and pressures, different pressures of the air gun produce. For example, when inflating the gas to the air gun at a high temperature, the pressure of the air gun increases. While inflating the gas to the air gun at a low temperature, the pressure of the air gun is insufficient. The pressure valve V of the gas cylinder magazine M is adjusted by the
rotation element 20 to drive thesecond spring 21 to push the definingsegment 231, and thedrive valve 23 is actuated by the definingsegment 231 to control the pressure of theintake room 111 to reach an airtight pressure value based on the using requirements exactly.
