PURPOSE:To easily perform switch operation by light operating force by utilizing an insertion gap with a rod for interlocking two valves to keep the connection between an inside chamber and an outside chamber of a valve chest. CONSTITUTION:An inside chamber and an outside chamber which are partitioned by respective valves 7, 8 are kept connecting each other through insertion gap 13 between a rod 6 and the values 7, 8. When a valve is switched to a position to let out compressed air from an air outlet 11, not from an air outlet 12 disposed on the second valve chamber 3, the pressure receive area is same at both end surfaces of the first valve 7, and as compressed ar does not work upon the outside of a valve seat 13 in the second valve 8, the valve can be self-locked at that position. At the point of time of second valve 8 floats from a valve seat 10, there is no difference in pressure receive area for the compressed air so that the rod 6 can be moved by light force. |
