Abstract
Abstract An all ports in body valve assembly wherein a reciprocable solenoid armature is received within a guide sleeve mounted on a body and a spring is drivingly connected between the armature and a rod carrying a valve member for sealing engagement with a valve seat in an arrangement wherein both the guide sleeve and valve member are isolated from armature impact forces upon energization. The valve seat is formed in an insert fitted in the body, and the insert provides fluid passages for communicating with ports formed in the body. An illustrative embodiment of the rod includes a terminal portion radially offset relative to the axis of movement of the armature and to the valve seat providing a valve assembly particularly suited for a three-way valve featuring an all ports in body construction.
