Scroll compressors

摘要

Scroll compressor may include, for example, a stationary scroll, a drive shaft, a crank shaft coupled to the drive shaft, a bush coupled to the outer surface of the crank shaft and a movable scroll coupled to the crank shaft. The movable scroll is preferably disposed adjacent to the stationary scroll. A boss may be coupled to the movable scroll and the boss preferably protrudes from the movable scroll at the opposite side of the stationary scroll. A seal is preferably disposed in a clearance defined between the bush and the boss. A compression chamber is defined by a space between the stationary scrolÜ and the movable scroll. Fluid is compressed within the compression chamber when the movable scroll revolves or orbits with respect to the stationary scroll. A discharge port is preferably defined within the movable scroll and is adapted to discharge compressed fluid to a side that is opposite of the stationary scroll. <IMAGE>
