Title:
LIQUID SPRING PRESSURE ACCUMULATOR WITH SELF-FILLING MECHANISM
Document Type and Number:
Japanese Patent JPS58166101
Kind Code:
A
Abstract:
A liquid spring accumulator includes a housing (60, 62) having inlet (72) and outlet (22) ports connected to a source (10) of liquid under pressure. The housing contains a high pressure chamber (64) and a cylindrical chamber (66) containing a spring-loaded piston (74). A rod (76) attached to the piston (74) is movable therewith into the high pressure chamber (64). A passageway (126) through the axis of the piston (74) and rod (76) provides communication between the inlet port (72) and the high pressure chamber (64) and includes a valve seat (132). A check valve member (130) in the passageway (126) includes a shaft (128) holding the movable member (130) off its seat (132) during initial flow of hydraulic liquid into cylinder (60), permitting flow to fill the high pressure chamber (64). As the liquid pressure increases, the initial movement of the piston (74) permits the check valve (130) to close, and still further increases in pressure cause the piston (74) to force the rod (76) into the high pressure chamber (64), substantially increasing its hydraulic pressure.
