Abstract

PURPOSE:To lower the rotor driving torque and to improve the sealing performance of a rotary vane compressor, by increasing the length of a back-pressure groove so that it is kept in communication with slide slots always during the compression cycle of the compressor, and providing an orifice in the back- pressure groove. CONSTITUTION:In a rotary vane compressor, in which high-pressure lubricating oil is supplied into slide slots 3c through a back-pressure groove 25c formed in the inner surface of a side plate 25, the length of the back-pressure groove 25c is so selected that the groove 25c is kept in communication with slide slots 3c always while a rotor 3 is rotated from an intermediate position of the expansion cycle of a vane 2 to a position where the compression cycle is completed. Further, since an orifice 25e is formed in the groove 25c at a position thereof where the orifice 25e is registered with the slide slot 3c when the vane 2 comes to a position where the expansion cycle is changed into the compression cycle, the lubricating oil is prevented from being enclosed in the slide slots 3c.
