Patent number: 4889471Abstract: In a scroll compressor, an open end of an oil extraction pipe which is placed in oil stored in a bottom portion of a hermetic casing is positioned at a location higher than an open end of an oil suction pipe that opens in the same stored oil, and a thermostat is provided for sensing a temperature rise of a compressed gas to cause the compressor to be stopped. Accordingly, even when an amount of oil injected into the compressed gas decreases, an amount of oil necessary for lubrication of a bearing portion is assured. The provision of the thermostat enables the compressor to be stopped before an amount of supply of the lubrication oil to the bearing portion has decreased. It is, accordingly, possible to positively prevent burning of the bearing portion of a crankshaft.Type: GrantFiled: July 7, 1988Date of Patent: December 26, 1989Assignee: Hatachi, Ltd.Inventors: Yasushi Izunaga, Hiroaki Kuno, Shintaro Sado
