COMPRESSOR UNIT Russian patent published in 2023 - IPC F04B35/02 F04B9/08 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering; it can be used in pumping systems, compressor and refrigeration equipment. A compressor unit contains cylinders with pistons, oppositely installed and rigidly interconnected with the formation of working and driven cavities, a partition separating driven cavities, a flow distributor, channels of high and low pressure, alternately communicating with driven cavities via the flow distributor. The flow distributor is placed in the partition, and it contains a chamber, in which a distributor spool is located with the possibility of axial movement, and a through hole, in which a switcher spool is located with the possibility of axial movement, on which pushers and a spring are installed. In the distributor spool, channels are made, communicating with driven cavities and channels of high and low pressure, and, on the switcher spool, grooves are made, communicating with the chamber and channels of high and low pressure. Moreover, a working body supplied to driven cavities can be gas, or steam, or liquid; and a working body supplied to working cavities can be gas or steam. Working bodies supplied to driven and working cavities can be both different chemicals and one chemical.

EFFECT: increase in the reliability of a compressor unit, increase in its manufacturability and compactness.
