摘要： A scroll type compressor including a drive shaft which is provided with a spiral groove formed in an external circumferential surface of the drive shaft. The spiral groove communicates diagonally between the oil space and the upper portion of the main bearing to ensure sufficient lubrication and sealing in the area where the drive shaft slide in contact with the main bearing. A seal bearing portion is positioned between the oil space and the low pressure space to isolate the oil space from the low pressure orbiting space, achieving an improvement in lubrication. The seal bearing portion is constituted with a seal washer, a seal bearing and a seal member, and, furthermore, with seal reinforcing material, to especially improve the seal between the oil space and the oscillation space.

摘要： In order to provide a simple structure to achieve sufficient lubrication and sealing in the various areas of a scroll compressor where sliding contact occurs, a spiral groove that communicates between a high-pressure side space and an area at an upper portion of a main bearing is formed on the external circumferential surface of the drive shaft where it comes in contact with and slides against the main bearing. A seal bearing is provided in a drive shaft-receiving block between the high-pressure side space and a low pressure side space to seal off the high-pressure side space from the low pressure side space. An oil supply hole is provided that communicates between the high-pressure side space and an oscillation space which is formed by an oscillating scroll member and an oscillating shaft. With this, a first oil passage that lubricates the main bearing and a second oil passage that lubricates an oscillating shaft-insertion hole are formed. A seal washer, the surface of which is polished to a specific roughness, is provided between the seal bearing and the drive shaft and, in addition, an elastic member is provided between the seal bearing and the block.

摘要： In a scroll type compressor, a simple structure provides oil intake assistance to ensure that lubricating oil in an oil space is induced into a spiral groove in correspondence to the rotation rate of a drive shaft. The drive shaft is provided with an inclined spiral groove which is formed in the external circumferential surface of the drive shaft. The drive shaft slides in contact with a main bearing. A leading end of the spiral groove, in the direction of the rotation of the drive shaft, communicates with the oil space and a trailing end of the spiral groove opens into the lubricating oil reservoir. The lubricating oil is supplied to the area where the drive shaft slides in contact with the main bearing by the spiral groove. Also, upon rotation of the drive shaft, intake of lubricating oil into the spiral groove is assisted when the suction force is reduced due to a high rotation rate.
