  • Hydraulic damper
    Patent number: 5597054
    Abstract: A hydraulic damper has a first oil chamber, a second oil chamber, a communication mechanism defining a communication oil passage, the first and second oil chambers communicating with each other through the communication oil passage, and a damping force adjusting mechanism for varying a cross-sectional area of the communication oil passage to adjust damping forces. The damping force adjusting mechanism includes an adjusting rod having an end disposed in a portion of the communication oil passage, the adjusting rod being movable toward and away from the communication oil passage to vary the cross-sectional area of the communication oil passage, an eccentric cam rotatably disposed in engagement with an opposite end of the adjusting rod, and a rotary actuator for rotating the eccentric cam to move the adjusting rod toward and away from the communication oil passage to adjust the damping forces.

  • Vehicle leveling system
    Patent number: 4709934
    Abstract: A vehicle leveling system employing pneumatic leveling units has a valve unit and a control device therefor for supplying a gas pressure from a gas pressure generator unit to and discharging it from the pneumatic leveling units. The control device comprises switches and a pressure sensor for detecting the gas pressure in the pneumatic leveling units and issuing a signal indicating the detected gas pressure, the control device including a central processing unit. The control device is operable in response to commands applied by the switches and the output signal from the pressure sensor, and has various control modes.
