IPC: F04C18/02
Filed: 2001-03-16
Abstract: PROBLEM TO BE SOLVED: To prevent the heat of an electric motor from being conducted to an oil tank and efficiently cool the oil liquid in the oil tank. SOLUTION: In the scroll type fluid machine, an inner side wall part 3B positioned on the lower side of a cylinder part 3 of a motor housing 2 is mounted apart downward from a fixing element 13 of the electric motor 12, and a circular-arc shaped heat insulating space 29 extending in the front/rear directions is formed between the fixing element 13 and the inner side wall part 3B. As a result, conduction of the heat generated when the electric motor 12 is driven to the oil tank 7 is prevented by the heat insulating space 29. Therefore, the increase of temperature of the oil liquid in the oil tank 7 with the heat of the electric motor 12 is prevented, so that the oil liquid can be cooled efficiently.
