ABSTRACT:
A pneumatic fluid control valve includes a valve body having a fluid inlet connectable to an external source of pressurized pneumatic working fluid, one or more load outlets, one or more corresponding exhaust ports, and a movable valve mechanism. The movable valve mechanism includes at least a pair of movable valve element and preferably resilient deformable connectors in a generally abutting relationship between adjacent movable valve elements for deformably transmitting coordinated motion therebetween. The deformable connector resiliently allows one of the movable elements to move and compress the connector before such coordinated motion is transmitted to the other movable element in order to minimize internal leakage.
