摘要： A discharge cut-off valve for an air compressor is provided. The discharge cut-off valve includes a hinged leaf valve within the recessed portion of a cylinder head manifold. The hinged leaf valve is rotatably anchored at a first end to a joint pin and is guided at a second end by a guide pin. In the on-load phase, the hinged leaf valve is seated over an unloader vent opening while a discharge vent opening is uncovered. In the off-load phase, the hinged leaf valve is seated over the discharge vent opening while the unloader vent opening is uncovered. As a result, compressed air is prevented from escaping the discharge port of the air compressor during the off-load phase, obviating the need for a down-stream turbo cut-off valve in an air dryer, for example.

摘要： A pressure monitoring device for use in an air system of a vehicle and for controlling a compressor comprises an input air connector for connection to an air tank and for receiving an input pressure from the air tank. A first signal air connector can output a pneumatic ON-load signal for adjusting the compressor to an operation mode. A second signal air connector can output a pneumatic OFF-load signal for adjusting the compressor to a non-operation mode.
