Abstract

PURPOSE:To perform lubrication to a working chamber at the time of starting by employing a valve made of a shape memory alloy to open or close a connection hole connecting a suction chamber to a back pressure chamber between two scrolls. CONSTITUTION:Connection holes 2d, 2e are provided to connect a suction chamber 12 to a back pressure chamber 20 of a fixed scroll 1. A valve 23 made of a shape memory alloy is arranged in a connection groove 22 connecting the connection holes 2d, 2e to the back pressure chamber 20. At the time of cold starting at low temperatures, the connection holes 2d, 2e of a whirl scroll 2 are in an open condition and therefore lubricant oil in the back pressure chamber 20, even at a high viscosity, can be introduced smoothly into a suction chamber 12 via the connection holes 2d, 2e. In this way, the lubrication to the suction chamber at the time of cold starting can be quickly performed.
