Abstract

PURPOSE: To improve the pressure override characteristic by connecting the pressure chamber contacting against a movable ring through a throttle while the pressure chamber of small pressure receiving face to the exhaust side of pump and the pressure control chamber of large pressure receiving face to a pressure control valve.
CONSTITUTION: Pressure chambers 14, 16 contacting against movable ring 5 are connected through throttle 17 while the pressure chamber 14 at small pressure receiving side is connected to the exhaust side and the pressure chamber 16 at large pressure receiving side is connected through electromagnetic valve 21 to pressure control valves 23, 24. Upon switching of electromagnetic valve 21, the piston 11 receives a function force in the direction of left caused by the difference of pressure receiving area to push the movable ring 5 to max. shifted position. When the exhaust pressure of pump increased to open the pressure control valves 23, 24, the liquid flowing into pressure chamber 16 is limited by throttle 17 to move the movable ring 5 quickly to the right. Consequently the exhaust amount is decreased resulting in improved pressure override characteristic.
