ABSTRACT:
A pressure control valve including an electromagnet portion, a pressure governing valve portion coupled to the electromagnet portion and hydraulic oil enclosed in said electromagnet portion. The pressure governing valve portion includes a valve sleeve and a spool valve slidably mounted in the valve sleeve so that an output pressure corresponding to an input signal to the electromagnet portion is provided. The electromagnet portion includes a push rod which slides in tandem with the spool valve, a core surrounding the push rod, a coil assembly disposed on the outer surface of the core, and a plunger secured to the push rod so that the spool valve slides responsive to the input signal. An oil passage is provided between the core and the coil assembly as that movable portions of the electromagnet portion move without any resistance from the hydraulic oil.
