ABSTRACT:
A solenoid valve with a ferromagnetic flux frame which, in assembly, locates and retains the components of the solenoid valve without an exterior housing. Preferably, the solenoid valve has an electric coil disposed on a tubular coil bobbin, a plunger received within the bobbin and first and second bodies each having at least one passage with the passages selectively communicated with each other by the plunger. The flux frame preferably has two complementary halves which when mated together interconnect the first and second bodies at opposed ends of the flux frame to retain and locate the parts of the solenoid valve without an overmolded or exterior housing. Preferably, the halves of the flux frame are mated with a snap-fit to facilitate assembly of the solenoid valve.
