Abstract
PURPOSE: To reduce the size of a cylinder for a compact device by making a bump and cavity on at least one of each opposed main piston and sub-piston into and out which one of those piston rods rubs.
CONSTITUTION: With a valve out of a view completely closed, a solenoid valve S is changed over to conduct P to A. so that an air pressure is supplied into a pipe 23 through a pressure reduction valve 15. Resulting left movement of a subpiston 6 is transferred to a piston rod 10 to cause a simultanous action of a main piston 5 in the same direction, which is inserted in a rod cavity 9 of the piston 6. The action is delivered through a pin 11 and a crankarm 12 to a valve switch spindle 3 to turn for a little opening of the valve. Then the solenoid valve M is changed over to conduct P to A so that air in a space A is released into atmosphere and simultanously an air pressure is given into another space B through a pipe 22 to make additional left movement of the piston 5. The spindle 3 makes additional turning to open the valve completely.
