The feature of this valve is to hold a constant pressure by controlling the position of the plunger equipped with a spool valve through the oil pressure in the feedback circuit. Also, in this valve, it is easy to obtain an arbitrary constant pressure by the simple manipulation. Firstly, both the structure and its principle of the action of the plunger-type pressure control valve are explained. Secondly, the dynamics of the plunger is analyzed linearly and the stability conditions are derived for a set of parameter values of the control valve made on trial. Finally, experimental studies are performed and both the pressure-flow characteristics and the pressureadjustment characteristics are examined. Throughout these analytical and experimental studies, the validity of the plunger-type pressure control valve is verified.}, pages = {121--132}, title = {A STUDY OF PLUNGER-TYPE PRESSURE CONTROL VALVE}, volume = {32}, year = {1984} }
