Abstract
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 pressurer 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.
Claims15
A pressure monitoring device for controlling a compressor, the device comprising:
- an input air connector connectable to an air reservoir and configured to receive an input pressure from the air reservoir;
- a first signal air connector configured to output a pneumatic ON-load signal to adjust a compressor to an operation mode;
- a second signal air connector configured to output a pneumatic OFF-load signal for adjusting the compressor to a non-operation mode.
A head unloader of a compressor, the head unloader comprising a first signal port and a second signal port, the first signal port being configured to receive a pneumatic ON-load signal for adjusting the compressor to an operation mode, and the second signal port being configured to receive a pneumatic OFF-load signal for adjusting the compressor to a non-operation mode.
A compressor for compressing air and outputting pressurized air, the compressor comprising a head unloader including a first signal port and a second signal port, the first signal port being configured to receive a pneumatic ON-load signal for adjusting the compressor to an operation mode, and the second signal port being configured to receive a pneumatic OFF-load signal for adjusting the compressor to a non-operation mode.
