Abstract:
A controllable solenoid valve having a sealed chamber that isolates the armature cavity from the function fluid or external water sources with oil or dielectric fluid and is ported to a reservoir or to a surrounding housing to maintain fluid communication with the armature cavity. The valve may also have a closed internal chamber filled with oil or dielectric fluid to maintain isolation of the armature cavity from the function fluid or other water sources. The closed chamber may also encompass the electrodes or the coil of the solenoid. In a preferred embodiment, the chamber is in fluid communication with transducers that sense fluid pressure.
