Title: Trigger valve
Inventor: SHIRASE SUGURU
IPC: B26D5/12
Filed: 1980-08-28
Abstract: PURPOSE: To have a rapid response to the change of pressure by making a movable valve with a diaphragm valve as major component.  
     CONSTITUTION: When a selector valve 22 is set to the change-over position 22a, the pressure air at a pressure source 18 flows into the pressure chamber 13 of a cylinder 1 through this selector valve 22 and piping 20 and also into another pressure chamber 12 through a piping 17. When the pressure in pressure chambers 12, 13 become the same, a piston 11 moves upward to stop in the uppermost position. At the same time, the pressure air flows into a trigger chamber 70 of a trigger valve 3 through a throttle 74 and piping 72. Therefore a movable valve 63 shifts downward to drive the valve part 64 apart from the valve seat 65 and thereby to release the valve chest 35 to a silencing chamber 52 through passage 69. The batting piston 31 stops when coming in contact with a stopper 46. The undersurface of the diaphragm valve 66 is driven by the pressure air in chamber 70 to come in contact with the valve seat 34. Thereafter the circumferential edge of the diaphragm valve 66 is deflected downward to separate the oversurface of the diaphragm valve 66 from valve seat 67, and thus the pressure air flows into the pressure accumulator chamber 29.
