摘要： PROBLEM TO BE SOLVED: To shoot a bullet with sufficient power regardless of the type of gun. SOLUTION: A blowback type gun comprises a member 14 having an opening 35 communicating with a pressure source and spring charged rearward by a slider 16 to move back and forth in order eject gas to a bullet, a piston means 32 disposed slidably on a cylinder section 31 at the rear part of the movable member 14 and receiving gas pressure from a gas opening 13, a tubular valve 33 disposed movably back and forth on the outside of a shooting gas passage 26 such that the valve 33 closes the opening 35 before gas is ejected, retracts to eject gas from a conducting part 36 lapping over the opening 35 into the gas passage 26 when gas is ejected and further retracts to close the opening 35 thus concentrating pressure entirely to the piston means 32. A gas pressure introducing section 38 for introducing pressure substantially to the entire area of a piston pressure receiving face is provided between the rear part of the tubular valve and the piston pressure receiving face so that the tubular valve 33 follows up the piston side through a charging spring 40.

摘要： PROBLEM TO BE SOLVED: To provide a rifle-type toy gun provided with a bolt-action mechanism, in which a strong bullet-shooting power is produced without decreasing gas pressure. SOLUTION: A cassette bullet-feeding part 52 and a gas-pressure accumulation chamber 53 are removably built in a housing 2 under a receiver 1. A functional part for bullet-placing/ventilation is formed in a bolt head 32 in the bolt-action mechanism to forcibly place BB shots, in the state of the bolt 33 being advanced and locked, into a barrel internal-tube 21, and besides constitutes a gas passage 32a between the outlet of a valve 63 placed in the chamber 53 on the side of a cassette 51 and a barrel internal tube 21. A valve opening mechanism (knocker 41, a plunger 66, and a rotating cam 54) is provided to instantaneously open the valve 63 in interlocking with an advance movement of a simulated firing pin 35 following the operation of a trigger 3. Thus, the gas passage can be shortened greatly as compared with the conventional art where the gas- pressure accumulation chamber is built in the stock.

摘要： PROBLEM TO BE SOLVED: To obtain a toy gas gun in which shooting pressure is prevented from lowering by forming a gas passage from a gas pressure accumulating chamber incorporated in a grip part to a shooting hole to have a single bend thereby utilizing gas jet pressure more effectively. SOLUTION: Working direction of a piston member 3 for opening/closing the valve 2 of a gas pressure accumulating chamber 53' and the direction of a first gas passage 10 guiding jetted gas are set substantially in parallel with the axis of a grip part 52. The first gas passage 10 is interconnected with a second gas passage 11 formed on the back of the shooting hole and the acting direction of the impact force of a trigger 59 is converted through a rotary cam 14 into the acting direction of the piston member 3 thus opening the valve 2. Since the acting direction of the piston member of the valve is matched with the impacting direction of the trigger in order to transmit the impact force linearly in the prior art, the gas passage bends twice to cause lowering of pressure and jetting speed of gas but that problem can be solved rationally by the inventive mechanism.
摘要翻译：要解决的问题：为了获得一种玩具气枪，其中通过从结合在抓握部分中的气体积聚室形成气体通道到射孔以防止喷射压力降低，从而具有单个弯曲，从而利用更多的气体喷射压力有效。解决方案：用于打开/关闭气体存储室53'的阀2的活塞构件3的工作方向和引导喷射气体的第一气体通道10的方向基本上与夹持部52的轴线平行。第一气体通道10与形成在射孔的后面的第二气体通道11相互连接，并且扳机59的冲击力的作用方向通过旋转凸轮14转换成活塞构件3的作用方向打开阀2.由于阀的活塞构件的作用方向与触发器的冲击方向相匹配，以便在现有技术中直线地传递冲击力，气体通道弯曲两次以引起压力降低和喷射气体的速度，但是这个问题可以通过本发明的机制合理地解决。
