Abstract

A sliding-vane compressor has a rotor 5 with recesses 13 in its periphery arranged to communicate with grooves 19 in an end wall of the housing for injecting a liquid, such as oil, or refrigerant, into the working chambers during periods when said chambers are out of communication with the inlet and outlet ports 8, 9. Valve members 14 may be rigidly connected to diametrically opposed vanes 11 so as to control communication between the grooves 19 and the recesses and fill the recesses when they are at the outlet ports 9. Alternative embodiments described with reference to Figs. 1-7 and Figs. 11 and 12 (not shown) differ only in the details. <IMAGE>
