ABSTRACT:
A scroll compressor has a wedge camming device operable between the orbiting scroll of the scroll compressor and a fixed wall forming part of the compressor, for the purposes of automatically engaging the wall and the orbiting scroll upon reverse operation of the compressor to thereby separate the wraps of orbiting and non-orbiting scroll during such reverse operation. Damage to the compressor in the event of powered reverse is also prevented.
