摘要： On an outside of a damper main body, there is provided a case which is movable up and down and which is connected to a damper rod. Between the damper main body and the case, there is formed a pressure chamber which is filled with a pressure medium which changes its state between a gaseous state and a liquid state. A heating chamber to flow therethrough a heating medium which is heated by the heat of the driving source or the like of a vehicle is disposed in a manner to contact a liquid sump portion of the pressure chamber. The pressure medium is heated and evaporated by the heat of the heating medium to thereby increase the internal pressure of the pressure chamber. The case is thus pushed upward and the damper rod is moved up, whereby the vehicle height increases.

摘要： A hydraulic strut having a damping rate that is variable includes a bypass valve which is operated to open and close by a gas spring supported within the piston of the strut. A main orifice plate divides an oil-filled cavity within the strut into first and second oil chambers, the orifice plate defining a primary orifice for passage of oil between the chambers. The gas spring includes an inner cylinder member affixed to the end wall of the piston, and a diaphragm slidably mounted within the cylinder member, the cylinder member and diaphragm defining a pressurized gas-filled cavity. The diaphragm supports a valve pin which is slidable within a passage in a tubular valve body, the valve body being fixed with respect to the piston, and the passage extending between the first and second oil chambers. Secondary orifices in the valve body communicate with oil in the first oil chamber. The valve pin includes openings which are alignable with the secondary orifices, the openings extending into an axial hole in the valve pin, the axial hole being in communication with the passage in the valve body. Compression of the strut causes compression of the gas spring, which causes movement of the diaphragm so as to move the valve pin within the valve body and thereby bring the openings in the valve pin into alignment with the secondary orifices in the valve body. Oil is thereby allowed to bypass the primary orifice and flow through the bypass valve between the oil chambers.

摘要： An improved hydraulic suspension unit has a springing force and rebound damping which are related to one another so as to allow certain wheel movements to occour without the resistance of rebound damping. A primary springing force provided by a pressurized gas, a coil spring and elastomer or any combination therof acts directly through the shock fluid via a floating piston, bladder or flexible diaphragm. The primary spring force acts directly through the shock fluid, and thus directly on a rebound damping valve so that the rebound damping valve is only able to dampen the stored energy. The spring provides a maximun in tuning and adjustment capability for varying conditions with easily variable reload and rate. The rebound damping valve can also be adjusted, both to determine the maximum rebound resistance when damping springing energy, and thus maximum shock shaft velocity, and to determine the magnitude of th shaft movements that are allowed to occur without rebound damping. Compression damping can also be adjusted independently of rebound damping, and provides very high flow rates, and a much more desirbale compression damping control. These adjustments can be made external to the suspension unit and require no disassembly. A lightweight vehicle is disclose which utlizes the improved hydraulic suspension unit.
摘要翻译：改进的液压悬架单元具有彼此相关的弹力和回弹阻尼，以便允许某些轮运动而不具有回弹阻尼的阻力。由加压气体，螺旋弹簧和弹性体或任何组合提供的主弹簧力通过浮动活塞，气囊或柔性隔膜直接作用于冲击流体。主弹簧力通过冲击流体直接作用，因此直接作用在回弹阻尼阀上，使得回弹阻尼阀只能抑制存储的能量。弹簧提供了一个最大的调谐和调整能力，适应变化的条件，容易变化的重载和速率。还可以调节回弹阻尼阀，以确定阻尼弹簧能量时的最大回弹阻力，从而确定最大冲击轴速度，并确定在没有回弹阻尼的情况下允许发生的轴运动的大小。压缩阻尼也可以独立于回弹阻尼进行调节，并提供非常高的流速，并且采用更加耐用的压缩阻尼控制。这些调整可以在悬挂单元的外部进行，并且不需要拆卸。公开了一种使用改进的液压悬挂单元的轻质车辆。

摘要： A self centering, bi-directional, non-cavitating damper that includes a cylindrical damper body and a piston assembly having a piston reciprocally movable in the damper body and a piston rod connected and movable with the piston. A tube is connected with the piston rod and is spaced about and radially from the damper body so that the tube and damper body may move axially, relative to each other, but are normally positioned in centered positions with respect to each other. First and second plastic washers are positioned between the damper body and the tube. At least one coil compression spring is positioned between the damper body and the tube and biases the washers apart axially to their normal positions. Each washer is prevented from moving apart beyond its normal position, but is movable toward the other washer, against the bias of the spring, when relative movement, from their normal positions, occurs between the damper body and the tube.

摘要： A shock absorber comprises a cylinder with a cylindrical bore, an actuator piston with a rod slidably received in the bore, and an adjustment piston slidably received in the bore and resiliently kept in a predetermined position. The adjustment piston cooperates with the actuator piston to define an adjustment chamber therebetween. The adjustment piston is movable in response to pressure developing within the adjustment chamber to vary a rate of air flow between the adjustment chamber and the ambient atmosphere so as to decelerate the actuator piston during its extending movement relative to the cylinder, thus providing a slow and gradual extending movement of the actuator piston.
