Solenoid valve

A solenoid actuated control valve comprising a body assembly including a body member having fluid inlet and outlet ports opening exteriorly thereof for connection with fluid conduits and first and second chamber bores opening outwardly therethrough and respectively partially defining first and second valve chambers, said body assembly including a pair of axially elongated tubular plunger sleeves attached to said body member and defining first and second plunger bores respectively communicating with said first and second chambers and having mounting means for securing said body member in fixed position on an associated supporting means, said body assembly including a cartridge member having connected first and second portions respectively received in said first and second chamber bores providing closures therefore and respectively further defining said first and second valve chambers and means for releasably retaining said cartridge member in assembly with said body member, a pair of valve seats in each of said chambers, means defining fluid passageways through said body assembly and communicating with said valve seats and said fluid inlet and outlet ports for defining fluid flow paths through said valve, a pair of solenoids each respectively mounted on an associated one of said sleeves, a pair of axially elongated plunger assemblies, each plunger assembly having a part thereof supported in an associated one of said plunger bores for axial shifting movement therein between one and another position, each of said plunger assemblies having a pair of seating surfaces thereon disposed in an associated one of said valve chambers, one of said seating surfaces engaging and closing one of said valve seats in said associated chamber when said plunger assembly is in one of its positions, the other of said seating surfaces engaging and closing the other of said valve seats when said plunger assembly is in the other of its positions, and means for biasing each of said plunger assemblies to and normally retaining it in one of its positions and yieldably resisting shifting thereof on energization of an associated one of said solenoids to the other of its positions to open said one of said valve seats and close said other of said valve seats, said cartridge member, said plunger assemblies and said biasing means comprising a cartridge subassembly which may be removed as a unit from said body assembly when said body assembly is mounted in fixed position on the supporting means by said mounting means and said inlet and outlet ports are connected to associated fluid conduit means.
