ABSTRACT:
A solenoid-operated fluid-flow control valve comprises a housing (10) incorporating a solenoid coil (14), a single armature (15) responsive to energization of the coil to determine a pressure differential across a pressure-sensitive member (28, 18) and to open an exhaust port (45), in combination with a valve assembly (13) comprising a hollow valve body (16), and a valve head (19), the valve body being axially movable with respect to the housing in response to the pressure differential acting on the pressure-sensitive member. The valve body and the valve head are relatively movable axially with the valve head being movable with respect to a seating (47) in the housing and a seating (23) on the valve body, whereby to provide selective communication between an inlet port (46), an outlet port (47) and the exhaust port (45).
