Title: Storage spring with pressure limiting valve - is used as pulsation damper and movable valve section is connected
Inventor: HAMMERSTEIN ALBERT DIPL-ING
IPC: F15B1/08
Filed: 1973-10-12
Abstract: Storage spring with a pressure limiting valve as a pulsation damper for a hydraulic circuit where the movable valve section of the pressure limiting valve is connected with the flexible component of the spring store. The flexible store component is a membrane and the movable valve section of the pressure limiting valve is a piston, which within a cylinder, more or less opens an overflow line on exceeding a given fluid pressure. The overlow leads to the suction side of the pump. The storage spring has the advantage of being a singly constructed unit combining both elements, and thus saves the need of a spring for restoring pressure, since both the storage spring and the pressure limiting valve require only a common spring.
