Abstract
A solenoid operated three port pressure control valve assembly of the exhaust pressure bleed type. The valve for the inlet pressure supply port includes a pressure responsive diaphragm with the supply port obturator attached. A bleed orifice in the diaphragm provides viscous dampening of the movement of the obturator and minimizes inlet valve flutter. The valve assembly is disclosed in both normally open and normally closed configurations.
