Abstract

PURPOSE: To prevent defective lubrication due to gasification of refrigerant by letting flow a part of refrigerant discharged from a displacement type pump mechanism part into an enclosed case through a bearing surface for lubrication, and cooling a stator with discharge flow flowing the inner face of the enclosed case.
CONSTITUTION: When a turning scroll 22 is turningly moved setting the eccentric distance between a stationary scroll 21 and the turning scroll 22 as the radius, a transport space 28 is periodically formed between laps 24, 27, and refrigerant is sucked from a suction pipe 33 and discharged to a discharge chamber 29. A part of the discharged refrigerant is supplied to a first and a second groove parts 48, 49 for lubrication, and the bearing surfaces of a thrust bearing part 30a and a bearing part 9a are lubricated. The major part of refrigerant in the discharge chamber 29 is discharged from a discharge pipe 47 through a back pressure chamber 37, a space 43a, and a space 43b, at this time, by the discharge flow of refrigerant flowing between a rotor 12 and the inner face of a case 6a, heat of a stator 11 conducted to an enclosed case 6 is removed, and the stator 11 is cooled.
