The filling and emptying sets up a piston action. Inlet and discharge flow paths are separated by closed sections between the inlet and discharge ports. The ports may be organised in either a cone or flat sided port plate.
Part of the liquid compressant passes out with the discharged gas and is removed in a mechanical separator. Makeup is regulated automatically by orifices or by manual adjustments.
Gardner Denver Nash manufacture vacuum pumps fitted with the inlet and discharge ports inside a tapered cone or flat port plate.

The Nash vacuum pump or air compressor has only one moving part--a balanced rotor. Such simplicity is possible because all functions of mechanical pistons or vanes are actually performed by a rotating ring of liquid compressant.
The rotor transmits power to keep the ring of liquid rotating. However, the liquid tends to follow a path that conforms to the inside of the body.
The body is cylindrical, but its axis is offset from the rotor axis. Liquid compressant almost fills then partly empties each rotor chamber once or twice each revolution.
