Device for sensing three pressures, particularly in pilot unit for relay valve of vehicle system of vehicle, has valve arrangement for selective adjustment of three pressures in sensor pressure fluid line and pressure sensor

摘要

The device has a valve arrangement for selective adjustment of three pressures in a sensor pressure fluid line (52) and a pressure sensor (54) for sensing the pressures. The pressure sensor is coupled with the sensor pressure fluid line. The pressure sensor is arranged at the sensor pressure fluid line and interacts with the sensor pressure fluid line and the valve arrangement, such that each pressure is selectively sensed by the pressure sensor.
