This paper describes the principle and the features of the liquid piston compressor (LPC). In the liquid piston compressor, the surface of the liquid moves the gas such like a conventional piston compressor, but the location of the piston can not be determined as a function of a rotation phase. Its location is determined by the running conditions at each moment. The liquid compresses the gas to outer side of the liquid and suctions the gas from the inner side. Suction volume is predicted as a function of the void fraction at the entrance of the working space. The disadvantage of the LPC is large diameter, but it is expected that LPC will have a small mechanical loss in comparison with a liquid ring compressor.
