Abstract:
1. An apparatus for preventing a reverse rotation of a scroll compressor including a casing, a fixed-scroll installed inside the casing, a orbiting scroll meshed with the fixed scroll and defining a compression unit therewith, a rotational shaft having a shaft portion coupled with a driving unit and an eccentric portion integrally formed to be eccentric from the center of one end of the shaft portion and a slide bush having a inserting hole therein and interposed between the eccentric portion of the rotational shaft and the orbiting scroll, wherein said apparatus comprises: the eccentric portion of the rotational shaft having two outer planes formed at an outer surface thereof, and a sloping plane extended from one of the two outer planes, the sloping plane sloping on the basis of a reference line connecting the axis of the shaft portion of the rotational shaft and that of the eccentric portion thereof; and the slide bush having two inner planes formed at an inner surface of the inserting hole thereof for confronting with the planes formed at an outer surface of the eccentric portion of the rotational shaft, and a sloping plane slopingly extended from one of the two inner planes on the basis of the reference line.
