Abstract
Slide valve assemblies are provided that have volume slide valve members that are self-positioning, as well as compressors that include such slide-valve assemblies. The self-positioning volume slide valve member automatically slidably adjusts to control compressor volume ratio and power input to the compressor during normal operation of the compressor. A positioning guide assembly includes a pinion gear and a movable rackshaft. The rackshaft engages the volume slide valve member and moves the volume slide valve member to an initial position when the rackshaft moves from a first position to a second position. Thus, the volume slide valve member may be placed in its initial position prior to normal operation of the compressor.
