Abstract
A solenoid-operated valve includes a valve body defining a valving bore for providing a path of communication between axially spaced inlet and outlet ports. A solenoid assembly is attached to the valve body and includes an inductor coil, a fixed flux guide and an armature, which is movable axially between a first position and a second position in response to electrical energization of the inductor coil. A valve member is disposed within the valving bore intermediate the inlet and outlet ports. An elongated control member interconnects the armature and the valve member for conjoined axial movement. A generally annular valve seat is disposed within the valving bore between the inlet port and valve member, the valve seat including a central through bore through which the control member extends.
