Claims

[Claims for Utility Model Registration] 8(1) In a hydro-pneumatic suspension in which the expansion and contraction of the suspension body causes pressurized fluid within the suspension body to move in and out of a gas-filled accumulator, the suspension body and the accumulator are During the pressure fluid path between the ori of the fluid path. A rotary shutter with adjustable shutter area is rotatably installed inside the shutter, and both ends of the rotary shaft of this shutter are extended outside the pressure fluid path, so that a surface facing one side in the axial direction of the shutter and a surface facing the other side in the axial direction of the shutter are A hydro-pneumatic suspension is characterized by equalizing the pressure-receiving area of hydraulic pressure on facing surfaces and connecting a rotating mechanism to one end of the rotating shaft. (2) ~ A plurality of channels are formed inside the shutter, which are interposed in the front brittle pressure fluid channel and whose orifice area is adjusted by rotation of the shutter, and a pressure fluid is provided in the channel in the shutter. Hydro-pneumatic suspension as described in Claim 1 of the Utility Model Registration Claim, which is equipped with a check valve that opens and closes depending on the Haramachi direction.
