摘要： The present invention relates to a scroll compressor, with an oil-separating driving shaft, that comprises a housing, a fixed scroll which is installed inside the housing, a swivel scroll which swivels around the fixed scroll, and a drive shaft which drives the swivel scroll. In the swivel scroll, a discharge hole is formed. A discharge path is formed along the longitudinal direction of the drive shaft so that discharged coolant from the discharge hole flows therethrough. At least, a part of the discharge path is inclined forward from the rotary axis to the exterior. A lubrication hole is formed in the drive shaft that penetrates from the discharge path to the outer surface of the drive shaft. Therefore, the disclosed scroll compressor may separate coolant gas and oil efficiently and discharge coolant in the drive shaft at the same time. In addition, oil separation is performed at a corresponding speed to the RPM of the drive shaft so the scroll compressor can handle the thermal load easily.

摘要： Provided is a housing integrated with an oil separating structure for a reciprocating compressor including a housing having a suction chamber and a discharge chamber, a cylinder block coupled with the housing and having a plurality of cylinder bores, pistons reciprocally accommodated in the cylinder bores, piston drive means for driving the pistons, and a valve apparatus opposite to bottoms of the pistons and having a suction port and a discharge port in communication with the suction chamber and the discharge chamber, characterized in that: the oil separating structure has an inner recess having a gas discharge port formed at its bottom, a peripheral recess formed around the inner recess and in communication with the discharge chamber, and an oil discharge port in communication with the inner recess in a circulation manner, which are integrally formed with each other; and the discharge chamber rather than the suction chamber is disposed adjacent to a center thereof. Therefore, since the oil is separated from the coolant introduced into the discharge chamber and reused, it is possible to increase efficiency and maintain durability of the compressor. In addition, since the oil separating structure is integrally formed with the housing, there is no need to provide a separate component for separating oil, and the housing can be readily formed to reduce manufacturing cost.

摘要： An oil separator of the present invention comprises a hollow outer body in which an inlet port and a drain hole are formed and an inner tube which is constantly distanced from the inner circumferential surface of the hollow outer body and comprises a discharge port in the center thereof. The inner circumferential structure guides the oil toward the opposite drain hole to the discharge port. The present invention is capable of maximizing oil separation through increasing centrifugal force. In addition, gas and oil are prevented from being remixed by guiding the oil separated by centrifugal force according to a screw and tapered portion so maximization of oil separation can be obtained.

摘要： Provided are a mechanism spring and a swash plate type compressor employing the same. The mechanism spring includes: a flat part having an insert groove formed at one side and into which a drive shaft is inserted, and two extension plates formed at both sides of the insert groove; a curved support part having two support plates disposed opposite to the two extension plates of the flat part, and bent toward the flat part in a convex manner when seen from a side view; and a curved connection part having two curved connection plates for connecting one ends of the two extension plates of the flat part to one ends of the two support plates of the curved support part. Therefore, it is possible to improve initial working performance of a compressor driven at a minimum inclination angle during operation of an air conditioner, and readily absorb shock due to rapid variation to the minimum inclination angle of the swash plate in a compression process during non-operation of the air conditioner. In addition, it is possible to readily perform their assembly and simplify the structure. Further, it is possible to prevent friction noise due to slide contact during operation of the compressor by securely fixing the mechanism spring to the drive shaft.
