摘要： A fluid squirt gun includes a linear flow path provided in a barrel, a nozzle at a tip end of the flow path, a valve seat provided in the flow path, a valve element disposed for movement in an axial direction of the flow path to open and close the valve seat, a spring for pressing the valve element in a valve-closing direction, and a trigger for opening and closing the valve element. The valve element includes a forward pressure receiving face on which fluid in the flow path acts in a valve-opening direction in a closed state of a valve and a reverse pressure receiving face on which the fluid acts in the valve-closing direction in the closed state of the valve and both the pressure receiving faces have substantially equal pressure receiving areas.

摘要： At a step of pressurizing a workpiece after reducing a speed of a piston rod at an end of a forward stroke of the piston rod by restrictively allowing compressed air to flow out of an exhaust-side pressure chamber, operation of a rapid exhaust valve is triggered by reduction of internal pressure of the exhaust-side pressure chamber to lower pressure than internal pressure of a pressurizing-side pressure chamber to thereby directly open the exhaust-side pressure chamber into the atmosphere through the rapid exhaust valve and rapidly reduce back pressure of a main piston remaining in the exhaust-side pressure chamber.
摘要翻译：在通过限制性地允许压缩空气从排气侧压力室流出的情况下，在活塞杆向前冲程结束后减小活塞杆的速度的工序后，触发快速排气阀的动作通过将排气侧压力室的内部压力降低到比加压侧压力室的内压低的压力，从而通过快速排气阀将排气侧压力室直接打开到大气中，并且快速地减少主活塞残留在排气侧压力室中。
