Abstract

PURPOSE: To prevent the reduction of the efficiency of energy consumption (EER) by communicating the intake chamber of a fixed scroll and a lubricating oil chamber with a pipe and providing a shape memory alloy spring controlling its switching valve.
CONSTITUTION: The intake chamber 12 of a fixed scroll 1 and a lubricating oil chamber 22 are communicated with a pipe 23, and its opening or closing is controlled with a shape memory alloy spring 24. The shape memory allow spring 24 is shrunk at the time of cold start, thus a gap is generated between the pipe 23 and a sealing valve 26, and lubricating oil 21 is guided to the intake chamber 12 by the pressure difference. The spring 24 is extended as the operation time elapses and the pipe 23 is sealed, but the viscosity of the lubricating oil 21 is low, and the lubricating oil flows into the intake chamber 12 through fine holes 2b, 2c and fed to a scroll sliding section. At the time of hot start, the pipe 23 is sealed, and oil is guided to the intake chamber 13 through the fine holes 2b, 2c. The oil feed to the scroll sliding section can be quickly performed, thus this is effective to prevent the reduction of the EER due to the mechanical loss such as abrasion.
