ABSTRACT:
Disclosed is a control device for use in fluid systems. In one embodiment the fluid is a liquid. A substantially cylindrical housing has therein a symmetrical cavity. The cavity is divided in upper and lower chambers by a circular and planar diaphragm. The upper chamber housing wall has protruding therefrom a cylindrical boss having a port for admitting a liquid. The boss forms a valve seat. The diaphragm has a plurality of concentric corrugations surrounding a central planar integral valve member. A media port in the lower chamber housing admits media for putting pressure on the diaphragm. When the pressure exceeds a predetermined value, the valve member closes upon the seat and entraps liquid between the diaphragm and upper chamber housing. The liquid acts to cushion, conforming to the shape of the diaphragm, thereby preventing damage to the diaphragm.
