ABSTRACT:
An electromagnetic solenoid operated plastic bodied appliance inlet valve having the armature, poppet, spring, elastomeric valve seat and plastic armature guide installed as a sub-assembly onto the valve body and secured thereon in fluid pressure sealing arrangement by weldment of a plastic retainer thereon. The electro-magnetic coil and pole frame are installed as a separate assembly. In one embodiment the valve inlet has a metal insert retained in the body by insertion of a metal spring clip and the body closed by weldment of a plastic cover thereover. In another embodiment the insert is retained by an annular ring received over the insert and secured to the body by weldment. The metal insert receives a threaded compression-type tube fitting for attachment of the supply tube. Reaction torque on the insert from the tube fitting is absorbed by the valve mounting bracket which engages hexagonal surfaces on the exterior end of the metal insert.
