Abstract

PURPOSE: To make the compressor in the caption possible to select optimum values of the amount of applied lubricating oil and of the amount of lubricating oil flowing into a compression work space by keeping an abutting force applied to the abutting surface of a fixed frame body on a turning end plate in a level of stabilized, moderately small value.
CONSTITUTION: An axial movement restricting plate 23 for restricting the axial movement of a turning spiral vane member 13 is located at a distance of a very small clearance from the back surface of a turning end plate 12. Further, on the back surface of the turning end plate 12, a circular, back pressure partion plate 24 is located so that it is slidable with respect to the back surface and seals the small clearance, and partions the clearance so that a delivery pressure acts on the center side of the back surface and a back pressure lower than the delivery pressure applies to a back pressure chamber 25 in the peripheral part. By circulating a lubricating oil in a space which the delivery side pressure is applied to, optimum values of the amount of lubricating oil applied to the bearing part and the amount of lubricating oil flowing into a compression work space can be independently selected respectively.
