Abstract: A rotary valve has a stator with ports for connection to a vacuum source and to a plurality of vacuum actuators, and a housing having a central hub. A selector residing between the stator and the housing comprises a resilient body insert molded to a steel drive plate having a central drive opening for receiving a drive shaft and an array of holes around the central opening. On one side of the plate the body comprises a valve member in contact with the stator and defines passages to selectively interconnect the ports, and on the other side of the plate the body comprises a resilient tubular spring surrounding the hub and pressing against the housing to bias the valve member against the stator.

Abstract: A two-piece housing defines a cavity containing electric switch elements and a detent mechanism positioned for optimum characteristics. Axially spaced apertures in the housing support a manually controlled shaft for rotation. The shaft is drivingly coupled to the movable switch elements and the detent mechanism. A floating valve assembly, operated by the shaft and aligned by the shaft, is mounted on the outside of the housing on projections which flexibly support a valve stator containing vacuum ports. A rotor holds a selector plate against the stator for interconnecting ports. The rotor is keyed to the shaft for rotation and is spring biased toward the stator.

Abstract: A vacuum valve having a compliable selector plate.

Abstract: A multimode push operated fluid flow selector valve is disclosed having modular construction including an individual slidable selector plate for each mode that is ported and cooperates with a common ported stator to effect the desired mode of communication.
