Abstract
A flow control device (10) is disclosed for achieving precision flow control over a wide range of inlet pressures. The device is particularly suited to household appliance applications where energy savings through hot water conservation are imperative. The device comprises a pressure responsive valve member (60) having a flanged portion (66) sealingly connected by a diaphragm (72) to the walls of a fluid chamber (52) defined by housing portions (28), (37). Flow passageways (84) are formed through diaphragm (72) and flange (66). A flow restricting opening is defined by the space between a control orifice (58) and a conical surface (70) on the valve member. An axial passageway (86) in the valve member communicates inlet fluid pressure to a compensating chamber (98) sealed from fluid pressure in the control chamber by a diaphragm (88) mounted thereacross and to one end of the valve member (60).
