Abstract

PURPOSE:To prevent the suction heating and improve the lubricity of a bearing surface and sealing performance between swirl bodies by forming an annular groove on a thrust bearing surface or the end plate of the second scroll in contact with the thrust bearing surface, opening an oil passage from the oil region in the high pressure environment and forming onto the end plate a passage communicating to the back surface chamber and a communication hole between the back surface chamber and an intermediate compression chamber. CONSTITUTION:The oil on the bottom part of a high pressure discharge chamber 74 is supplied into an annular groove 5 and circulates on the whole periphery, and oil lubricates a thrust bearing surface 3 and smoothes the revolution operation of the second scroll 2. Further, the oil is discharged into a back surface chamber 8 from an outer peripheral edge part 20, passing through a radial direction passage 6, and supplied into an intermediate compression chamber M through a communication hole 9. Since almost all portions of the oil used in the oil supply onto the thrust bearing surface 3 is discharged onto the back surface chamber 8 side without oozing to a suction chamber 72 side, the suction heating can be suppressed, and since the compression chamber in which oil pouring is carried out is the intermediate compression chamber M positioned in the intermediate part of a swirl, oil can be supplied favorably into the sliding parts of the swirl bodies 12 and 22, and the sealing performance between compression chambers A and B can be improved.

Further, between the upper member (43) on the cross section (45) and the end plate (21) of the second scroll (2), the end plate (21)
An annular seal ring (81) is interposed that divides the back surface of the chamber into a center and an outer periphery, and a back chamber (8
). In this way, the back chamber (
The reason why 8) is limited to the outer periphery of the second scroll (2) is because
The internal pressure of the casing (1), that is, the high pressure, acts on the center, and the back pressure of the end plate (21) of the second scroll (2) is compressed so that it gradually increases from the outer periphery toward the center. This is to match the internal pressure of the chamber and the magnitude of the separation force from the compression chamber.
