Abstract

PURPOSE:To facilitate lubrication to bearings at the time of cold starting by connecting a back pressure pipe with both an intake pipe and a delivery pipe, and providing a pressure regulating valve at a junction thereof. CONSTITUTION:A back pressure pipe 20 extracting the pressure of a back pressure chamber 20 is connected with both an inlet pipe 11 introducing refrigerant gas to the inlet chamber 12 of a static scroll 1 and a delivery pipe 19 discharging compressed refrigerating gas so as to provide a pressure regulating valve 23 at a junction thereof. At the time of starting where lubricant 21 is low in temperature, refrigerant gas does not smoothly flow in to the inlet chamber 12 from the back pressure chamber 20, the medium in the back pressure chamber 20 becomes high in pressure, following which, a piston 25 is pushed to the delivery side 19 so as to open the pressure regulating valve 23 for introducing highly pressurized refrigerant gas in the back pressure chamber 20 to the inlet pipe 11. This constitution thereby can facilitate sufficient lubrication to both an auxiliary bearing 7 and a main bearing 8.
