Abstract
Disclosed are several embodiments of a stopping device operable between the drive shaft and/or orbiting scroll of a scroll compressor and a fixed wall forming part of the compressor, for the purposes of automatically engaging the wall upon reverse operation of the compressor to thereby quickly stop such reverse operation. Damage to the compressor in the event of powered reverse is also prevented, either by permitting the machine to run free or by quickly stopping it. Also disclosed are several ways to facilitate start-up with weak motors.
