Solenoid-Actuated Fluid Control Valve Assembly

摘要

A valve assembly includes a valve base having a tubular section with a longitudinal bore formed therein, a fluid inlet port and a common port with an internal passageway therebetween. A solenoid coil is adapted to generate a magnetic flux and includes a longitudinal axis and a bore coaxial therewith. The valve assembly further includes an orifice piece positioned within the longitudinal bore of the valve base. The orifice piece includes a central passageway with a first end and a second end. A plunger is movable within the longitudinal bore between a first de-actuated position and a second actuated position.

1. A valve assembly comprising:
a valve base including a tubular section with a longitudinal bore formed therein, a fluid inlet port and a common port with an internal passageway therebetween; a solenoid coil housing, having a longitudinal axis and a bore coaxial therewith; an orifice piece positioned within the longitudinal bore of the valve base, said orifice piece defining a central passageway and having a first end and a second end, wherein a channel is formed between an outer surface of the orifice piece and said longitudinal bore to allow fluid transfer from the central passageway at the first end of the orifice piece to the common port of the valve base; a magnetic top piece positioned over a top open end of the tubular section; a plunger having a first end, a second end, a cylindrical outer surface and fluid flow path formed between said first end to said second end, said plunger being movable within the longitudinal bore between a de-actuated position and an actuated position; and a flux conductor.
