  • Patent number: 6260677
    Abstract: 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).

  • Patent number: 6247683
    Abstract: A case is provided on an outside of a damper main body that is connected to a damper rod and which can freely move in vertical directions. A pressure chamber is formed between the damper main body and the case in which a pressure medium is sealed up, which pressure medium changes its phase between vapor and liquid phases. The pressure medium is heated and vaporized by heat generated by virtue of a damping effect of the damper, while the pressure medium is condensed by virtue of heat radiating from the case by running wind. During the running on a rough road when the heating value of the damper becomes large, the internal pressure of the pressure chamber is increased to thereby raise the vehicle height, and during the running at high speeds when the heat radiating value becomes large, the internal pressure of the pressure chamber is decreased to thereby lower the vehicle height.

  • Patent number: 6179098
    Abstract: In a vehicular damper with a vehicle height adjusting function, a pressure source for adjusting the vehicle height is integrally assembled into the damper to improve the ease with which the damper is assembled into a vehicle body. For that purpose, on an outer peripheral portion of a damper main body there is provided a case which is connected to a damper rod and which is vertically movable. A refrigerant which varies between a gaseous phase and a liquid phase is contained in the case in a hermetically sealed manner. An electric heater is disposed inside the case to heat and evaporate the refrigerant by the electric heater. The vehicle height is increased by an increase in the vapor pressure inside the case.

  • Patent number: 6170621
    Abstract: 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.

    Abstract: A vessel of a liquid pressure generating apparatus is divided into two vessels of an upper liquid pressure generating vessel containing therein a liquid chamber whose volume can be varied, and a lower medium vessel into which is filled a medium which varies between a gaseous state and a liquid state. Both the vessels are connected by a communicating passage. The two vessels are respectively provided with heating heat exchange portions into which is inputted an external heat such as a waste heat of a driving source of a vehicle. The medium vessel is also provided with a cooling heat exchange portion. By the inputting of heat and stopping thereof, the liquid pressure can be controlled with good response.

  • Patent number: 5545023
    Abstract: A pressure molding apparatus for molten resin in which an oil-pressurized cylinder internally holding an end of gate pin can freely move in compatibility with thermal elongation or contraction of a manifold pipe. In addition, a limit switch to be activated by the descending movement of this cylinder in correspondence with the descending movement of the gate pin is interlinked to a molten-resin supply source. By provision of these mechanisms, molten resin can smoothly be delivered to the interior of a molding unit without obstruction. Since substantial space is provided around this cylinder, pipes can easily be installed. Furthermore the inner later surface of the gate aperture on the side of the gate pin is provided with an obtuse angle wider than the tip angle of the gate pin, and a tapered hole having an adequate length and tapered diameter expanding itself from the gate aperture to the inner surface of the molding unit is provided.
