Abstract

PURPOSE:To reduce a sliding loss in a rotary compressor by providing a vane back pressure chamber behind a vane and an oil pass between the chamber and an oil puddle in the closed casing of the compressor, said oil pass communicating with the chamber only when the vane runs through a given rotary angle near the top dead center of the vane. CONSTITUTION:Behind a vane 6, a vane back pressure chamber 12 is provided which is closed by a cylinder 1, a top plate 10, and a bottom plate 11. Further, an oil pass 15 is provided between the vane back pressure chamber 12 and an oil puddle 16a in a closed casing 16. Only when the vane 6 runs through a given rotary angle near the top dead center of the vane 6, the oil pass 15 communicates with the chamber 12 and the high pressure lubricating oil from the oil puddle 16a is introduced into the vane back pressure chamber 12 through the oil pass 15. This reduces the sliding loss of the vane top and ensures a satisfactory lubrication for the vane.
