  • Publication number: 20190178334
    Abstract: According to one embodiment, a damper device includes a rotator, a first oscillator, a second oscillator, and two rollers, for example. The rotator is provided with a first opening. The second oscillator includes two guide surfaces recessed in a direction closer to a first center of rotation and a transmitting part capable of moving along the first opening. The two rollers each include a ring supported by the first oscillator and a shaft extending along a second center of rotation inside the ring and rotatably supported by the ring. The shaft comes into contact with a corresponding one of the two guide surfaces of the second oscillator pushed outward in the radial direction by centrifugal force, rolls along the corresponding one of the two guide surfaces by oscillation of the first oscillator, and is pushed by the corresponding one of the two guide surfaces in the circumferential direction.

  • Publication number: 20190176562
    Abstract: A vehicle-height control system including a tank, a compressor, an actuator, and a valve between the tank and the compressor. The valve is closed to a state of a pressure medium supplier to the compressor-pressure supply state when a tank pressure has reached a threshold in a tank-pressure supply state in which the tank pressure is supplied to the actuator. In the compressor-pressure supply state, the tank pressure is kept at the threshold, and a pressure in the actuator is greater than the tank pressure. The threshold makes it difficult for a pressure differential in the valve to become greater than a valve-opening pressure differential, making it difficult for the valve to be opened in the compressor-pressure supply state. This system enables good supply of a pressure medium from the compressor to the actuator, avoiding a longer time for vehicle height control and achieving a shorter compressor operation time.
