Abstract:
1. A method for forming a variable flow valve comprising: providing a valve body having an externally threaded section, a valve element chamber, an outlet port, and an inlet port, the valve element chamber defining a valve seat, the outlet port being formed through a first axial end of the valve body and intersecting the valve chamber radially outwardly of the valve seat, the inlet port having a first portion, which intersects the valve seat, and second portion that is in fluid communication with the first portion and which extends transverse to a longitudinal axis of the valve body; providing a valve element guide that defines a valve element channel and a rod channel; installing a valve element to the valve element channel in the valve element guide; installing the valve element guide in the valve element chamber such that the valve element is movable along the longitudinal axis between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is spaced apart from the valve seat by a predetermined distance; installing a valve actuator guide into the valve body and in abutment with the valve element guide, the valve actuator guide including a guide bore formed therethrough coincident with the longitudinal axis; providing a plunger assembly having a rod and an armature; positioning the rod through the guide bore and the rod channel such that the rod is abutted against the valve element and the valve element is abutted against the valve seat; moving the armature on the rod such that a first surface on the armature is spaced apart from a second surface on the valve actuator guide by a predetermined distance; and securing the rod to the armature.
