Abstract
A wet plunger type solenoid primarily for use with hydraulic valves adapted for high pressure hydraulic fluid systems, the armature assembly being constructed so that a stainless steel armature tube can be employed to provide a strong plunger chamber that will withstand high pressures of the hydraulic fluid, and the armature tube and the associated yoke and stop pieces at the ends of the plunger chamber are arranged so that the non-magnetic tube does not cause an 'air gap' in the magnetic fluid of the solenoid, thereby allowing the solenoid to operate at lower electrical loads and temperatures.
