ABSTRACT:
A solenoid valve comprising a housing having opposed inlet and outlet ports which communicate via a passage containing a poppet member movable in response to energization of a coil is disclosed. A flexible wall is further provided in said passage to define inlet and outlet chambers communicating respectively with said inlet and outlet ports. A second passage in said flexible wall connects said chambers, and a resilient spring urges a valve seat defined in said second passage into fluid tight engagement with the poppet member, whatever the position of the latter. The poppet member is movable between a first position in which it urges the wall against an abutment, thereby preventing any communication between the inlet and outlet ports, and a second position in which the wall is movable relative thereto, whereby said wall acts as a non-return valve between the inlet and outlet ports.
