Abstract

PURPOSE:To improve the response characteristic to the transient by providing a piston chamber, to which pressure oil is supplied from an oil hydraulic pressure supplying means adjusting a delivery pressure, in a pressure reducer main unit here inserting a piston unit into the inside and mounting a control pressure adjusting spring member to be interposed between the piston unit and a pressure reducing valve. CONSTITUTION:By controlling a hydraulic pressure adjusting means 61 using a control means in a pressure of oil in a piston chamber 44, a piston unit 45, inserted into the piston chamber 44, is pressed by a control pressure adjusting spring member 32, moving. By this action, the control pressure adjusting spring member 32 extends and contracts causing a pressure reducing valve 7 to singly move independently of a low speed valve 21, and a pressure of control oil, delivered from a control oil passage 5, comes to promptly change.
