HIGH-PRESSURE COMPRESSOR AND METHOD OF ITS OPERATION Russian patent published in 2011 - IPC F04B25/00 

FIELD: engines and pumps.

SUBSTANCE: high pressure compressor (1) for gases compression with, at least, two working cavities (3, 3') that can be partially adjusted between one-stage operating position, in which compressed gas is compressed in one stage, and multi-stage operating position, in which at least one working cavity (3') is sequentially connected to, at least, one sequential working cavity (3). There provided are, at least, three working cavities (3, 3') that have equal working volume. All working cavities (3, 3') are connected in parallel between themselves in one-stage working position.

EFFECT: there is a possibility of effective compression of gases that have significantly different pressure levels at the input of high-pressure compressor.
