<p>A gas actuating device (2) includes a housing (4) having a gas applying chamber (6), an actuator chamber (8) and a gas applying passage for communicating gas from the gas applying chamber (6) to the actuator chamber (8). An actuating member (12) having a first side (22) and a second side (24) is disposed in the actuator chamber (8), wherein the first side (22) of the actuating member (12) receives gas pressure from gas applied to the actuating chamber (8) from the gas applying passage (6). The actuating member (12) moves in a first direction in response to the gas pressure applied to the first side (22) of the actuating member (12). A valve (31) selectively communicates compressed gas from the gas applying chamber (6) to the actuator chamber (8) through the gas applying passage (10) for moving the actuating member (12) in the first direction, and a gas release passage (11) communicates gas from the actuator chamber (8) at the first side (22) of the actuating member (12) to an outside of the actuator chamber (8). <IMAGE></p> |
