Title: Hydraulic damper
Inventor: KAGAWA SHINICHI
IPC: F16F9/342
Filed: 1990-03-15
Abstract: PURPOSE:To effectively secure buffer action even when impact cushioning material and the like are concurrently used by making up a free piston out of a pressure valve body which opens an orifice passage when pressure within one oil chamber exceeds specified one, and of a sliding member capable of sliding toward the pressure valve body within a set range. CONSTITUTION:A free piston 21 is made up out of a sliding member 22 which is slidably coupled in an inner cylinder 5, and of a pressure valve body 23 which is slidably coupled in the aforesaid member, and the pressure valve body 23 is partitioned into a gas chamber A and an oil chamber B via the sliding member 22. In this case, the pressure bearing area of the pressure valve body 23 is made large at the gas chamber A side, but small at an oil chamber C side. When impact cushioning material is concurrently used, the cushioning medium keeps the pressure valve body 23 in a valve closed condition by means of gas pressure PA within the gas chamber A in an early stage of absorbing impact energy, so that the inner cylinder 5 is restrained from being moved into an outer cylinder 1 in the direction of F. When pressure within the oil chamber C exceeds specified one PC, the pressure valve body 23 is parted from the end face of a piston 9, so that the oil chamber B and C are mutually communicated through an orifice passage 12.
