STRUCTURE FOR REDUCING VENTILATION OF OIL FOR SCROLL COMPRESSOR

摘要

PURPOSE: A structure for reducing a ventilation of oil is provided to solve a problem generated by a leakage of oil by reducing an amount of ventilated oil with changing a flowing path of oil flowed with a coolant in a ventilating step of coolant. CONSTITUTION: An end plate face of a rotating scroll(10) is tapped and an inner wall of a processing hole is to be a groove(45) of screw having a pitch(43). Because the pin(44) generates a resistance of passage and a limited passage, that is a capillary tube(40), is offered via the pitch(43) when a pin(44) is inserted therein, the processing property is improved. And an installation is easy because it is to be the capillary tube when the pin(44) is hammered. A flowing path of oil is controlled by extending a capillary passage to a ventilating groove of oil(41) without punching to penetrate the groove of screw in the rotating scroll(10). Oil gathered in the end plate face makes the long passage by falling via a hollow of the pitch(43) between the pins(44). And a sufficient resistance of passage is obtained. Thereby an effect faced with an efficient characteristic of a variable scroll compressor is minimized and an increase of ventilating amount according to an increase of a lubricating amount at a rotation of high speed is prevented.
