ABSTRACT:
A pressure control valve of a hydraulic control system of automatic transmissions has reducing pressure PR supplied from a reducing valve by duty control of a pressure control solenoid valve controlled by a transmission control unit thereby changing line pressure PL supplied from a manual valve into the control pressure and supplying the control pressure to the friction element. The valve comprises a valve spool operated by the duty-controlled reducing pressure, a valve body in which the valve spool linearly moves, and a feedback line which communicates the control pressure with one side of the valve body thereby reducing the deviation of the control pressure.
