<p>PROBLEM TO BE SOLVED: To provide a compact air distributing-discharging valve by combining a rotary distributing valve and a direction control spool valve connected to each other by a first passage and a second passage to alternately supply and discharge air from the spool valve to first both ends and second both ends of a rotary valve. SOLUTION: When a directional control spool 30 is moved rightward by a pneumatic actuator 37 through a control rod 38, when a right side surface A and a rotary valve 21 rotate in a port Y toward an intake air port Y in a port W, pressurized air is supplied to a cavity S1 through a slot 26 of a rotary valve 21 to be connected in order to respective cylinders. When the spool 30 exists on the right side, a cavity T1 connected to a port X through the slot 26 is ventilated so as to discharge the air through a channel X1 in a motor body. When the spool 30 moves leftward, the pressurized air is ventilated toward the port X and the cavity T1, and discharge air is ventilated to the motor body by Y1 through the port Y.</p> |
