Abstract

See full text

A valve including a valve body having a surface with a plurality of orifices with a resilient closure membrane adjacent thereto is disclosed. The membrane is positioned to yield in response to a pressure differential so as to permit flow between respective ports. A male closure member is mounted to selectively urge the membrane into contact with the periphery of an orifice in order to prevent liquid flow therethrough in accordance with a desired flow arrangement. Further refinements include spring biasing of the closure mechanism, which in one construction has a movable carriage provided with a roller.
