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.

摘要： A compressor for a vehicle air supply system includes a manifold, a cover, a gasket, an inlet, and an outlet. The manifold and cover are fixedly stacked together, and define a fluid channel system between them. The gasket extends laterally from between the manifold and cover. The fluid channel system includes an inlet air passage extending from the inlet to a cylinder inlet, a discharge air passage extending from a cylinder outlet to the outlet for discharging compressed air to the outlet, and one or more coolant channels that can be fed with a coolant to cool least the discharge air passage. The inlet air passage, the discharge air passage, and the coolant channel(s) extend laterally, defined by wall faces of the discharge air passage. The wall faces comprise turbulator fins protruding into the discharge air passage. The turbulator fins create turbulence in the discharged compressed air flow.

The fluid channel system includes an inlet air passage extending from the inlet to a cylinder inlet, a discharge air passage extending from a cylinder outlet to the outlet for discharging compressed air to the outlet, and one or more coolant channels that can be fed with a coolant to cool at least the discharge air passage. The inlet air passage, the discharge air passage, and the coolant channel(s) extend laterally, defined by wall faces of the discharge air passage. The wall faces comprise turbulator fins protruding into the discharge air passage. The turbulator fins create turbulence in the discharged compressed air flow.

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.
