Abstract
A compressor includes a slide valve () having a passage that can be in fluid communication with a discharge plenum () and a suction plenum (). The slide valve () position may be axially adjusted to control an amount of refrigerant that is compressed between a male rotor () and a female rotor () in the compressor based upon a system control scheme that determines capacity demand. The passage () is in fluid communication with the discharge plenum () and the suction plenum () when the slide valve is in a fully unloaded position or a partially unloaded position. A compressor housing blocks an opening to the passage when the slide valve () is in a fully loaded position. The location of the opening () in the slide valve determines what point in axial travel of the slide valve that fluid bypass begins.
