摘要： On an outside of a damper main body (1) of an inverted type of damper, a cylindrical case (12) which is coupled to a damper rod (2) is provided so as to be movable up and down. Between the damper main body (1) and the case (12), there is formed a pressure chamber (13) filled with a pressure medium of low boiling point which varies between a gaseous state and a liquid state. By use of a heater (16) which is disposed inside the pressure chamber (13) the pressure medium is heated and evaporated, whereby the vehicle height is increased by the vapor pressure of the pressure medium. In the above-described damper with a vehicle height adjusting function, the heater (16) is arranged to be easily mounted and dismounted to thereby improve the ease with which the maintenance is performed. The influence on the suspension stoke which is caused by the presence of the heater (16) is also minimized. The heater is formed into a bar heater (16). This bar heater (16) is horizontally inserted into the bottom of the pressure chamber (13) through a connector portion (12d) which is provided in the case (12). A tail portion of the bar heater (16) is fitted into the connector portion (12d) in a threaded manner.

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： The hydraulic pressure to be supplied to a hydraulic actuator mounted on a vehicle, such as a hydraulic cylinder for vehicle height control, is arranged to be generated by utilizing a waste heat of a power source such as an engine of the vehicle or the like. There are provided an oil chamber to be connected to a hydraulic actuator, a pressurizing chamber containing therein, in a sealed manner, a medium which varies between a gaseous state and a liquid state, and a heating device which heats and evaporates the medium inside the pressurizing chamber and through which cooling water for cooling the power source to be mounted on the vehicle flows. The hydraulic pressure is generated by compressing the oil chamber by a vapor pressure of the medium inside the pressurizing chamber. In case the hydraulic actuator is a hydraulic cylinder for a vehicle height control, there is provided a flow control valve which controls the amount of supply of the cooling water to the heating device depending on the vehicle height.
