The operation of the screw compressor may be advanced or eased off depending on the motion of the reciprocating compressor.

The operation of the screw conveyor may be advanced or eased off depending on the motion of the reciprocating compressor.

The operation of the screw compressor may be advanced or eased off depending on the motion of the reciprocating compressor.

The drive means (22) connects the working engine (16) to the compressor (12) such that operation of the working engine ( 16) causes operation of the compressor (12).

In accordance with present invention an optimal speed for operation of the compressor is determined at which the compressor will operate along a peak efficiency operating line of a compressor map thereof.

Testing is accomplished while the air compressor is in service and mounted onto the engine of the vehicle.

The motor drives a compressor (20), while the electromagnetic bearings support the motor rotor (178) during operation of the compressor.

The operation of the air compressor (2) is controlled by the control circuit (1).

Operation of the compressor produces a fluid stream through the motor housing.

Thus, noise and vibration generated during the operation of the compressor can be considerably reduced.

Verify operation of compressor and electrical resistance

It also has the functions of controlling the compressor.

The compressor is running quietly and almost vibration-free.

The system is monitored to determine when the control system has signaled for the compressor operation to stop but the compressor has, in fact, continued to operate.

During the operation of the compressor, the noise of liquid is heard and when
