摘要： A rubber valve plate is sandwiched between a stator and a cover. Ports in the stator for coupling to a vacuum source and vacuum motors are aligned with poppets molded in the valve plate. A manifold in the plate joins regions surrounding the valves to couple the vacuum source to all the valves. Openings in the cover plate allow a dome of each poppet to protrude. A rotary actuator adjacent the cover is configured to selectively engage the domes to actuate certain poppets which are moved against the stator to close the port to vacuum or are allowed to move toward the cover to connect the port to vacuum.
