Abstract
A vacuum regulating valve has a poppet type valve element supported so as to be brought into uniformly close contact with a valve seat disposed in a passage connecting two main ports. The valve element is connected to a valve stem by a connecting mechanism that allows the valve element to tilt relative to the valve stem. A piston included in a cylinder actuator moves the valve stem axially.
