HYDRAULIC VALVE-PRESSURE RISE RATE REGULATOR Russian patent published in 1997 - IPC

Abstract RU 2092720 C1

FIELD: mechanical engineering; power hydraulic drives. SUBSTANCE: proposed valve is made on base of indirect-acting hydraulic valve built in special body with pressure regulator screwed in it. It consists of cylinder with spring-loaded piston inside it, stop and sealing rings. Hydraulic line connecting the regulator with valve passes after main valve of hydraulic indirect-acting valve. Diameter of piston and spring are so selected that opening of main valve is ensured at preset rate of pressure rise. EFFECT: enhanced efficiency. 2 dwg
