Abstract
A solenoid valve assembly comprising solenoid windings positioned around a central core and a movable valve element arranged on the axis of the windings, the windings being supported by a spindle having a boss adapted to be received in an opening formed in a body at one end of the spindle and a fluid fitting adapted to establish a connection with a pressure line at the opposite end of the spindle, and sealant structure for sealing the interior of the spindle from external contaminants including an encapsulation material surrounding the spindle and the windings.
Claims5
A solenoid valve assembly comprising a spindle with a central opening, a movable valve element in said opening, an electric coil surrounding said central opening;
- a fluid fitting at one end of said opening, a mounting boss at the other end of said opening;
- a valve orifice in said spindle adapted to register with said valve element when said coil is deenergized, said valve element and said valve orifice thereby providing controlled fluid flow through said central opening;
- sealant material surrounding said spindle;
- and
- an encapsulation enclosing said spindle and compressing said sealant material against said spindle thereby hermetically sealing said coil.
A solenoid valve assembly comprising a movable valve element and an electric actuator coil;
- a control fluid flow passage structure including a valve orifice element, said movable valve element being adapted to register with said valve orifice element, said valve element and said orifice element thereby providing controlled fluid flow in said passage structure;
- sealant material surrounding said passage structure;
- and
- an encapsulation enclosing said actuator coil, said valve element and said passage structure and compressing said sealant material against said passage structure thereby hermetically sealing said valve assembly.
