Abstract
A pump-ejector compression unit is furnished with a receiver, and a mixing chamber of a liquid-gas ejector and a separator are located inside the receiver. An outlet of the mixing chamber is connected to the separator, the receiver is partly filled with a motive liquid, the liquid outlet of the receiver is connected to the suction side of a pump and the gas outlet of the receiver is connected to a consumer of a compressed gas. There is another embodiment of the compression unit, wherein the mixing chamber outlet is connected to a chamber for conversion of a gas-liquid flow. The introduced pump-ejector compression unit has an increased efficiency factor.
