LEVELING VALVE

摘要

The leveling valve is provided with: a seat for defining a flow channel that communicates with an air spring and a compressed air source or a flow channel that communicates with the air spring and a drain; a valve that moves in the axial direction in response to a relative displacement of the vehicle body with respect to the chassis; a spring for biasing the valve towards the closed position in which the valve abuts against the seat; a valve guide, which supports one end of the spring and is inserted so as to slide freely with respect to the inner surface of the housing wall; and a communication port, which is open at the inner surface of the housing wall. The area of movement in which the valve guide moves is set in a location that is offset in the axial direction from the communication port.
