Abstract
A valve for compressor clearance or by-pass control for a gas compressor having a compressor cylinder which includes a tubular member having a bore communicating with the compressor cylinder, an outer surface and an opening. A valve sleeve receives the tubular member therein and is slidably movable with respect thereto between an open position whereat one of a clearance pocket and a suction chamber communicates with the compressor cylinder through the opening and a closed position closing the opening. A plug is positioned in the tubular member bore and reduces the amount of clearance in the compressor cylinder. Actuator means is provided for moving the valve sleeve between its open and closed positions. The tubular member is attached to an outboard side of a suction valve assembly, and the bore thereof communicates with a passage extending through the suction valve assembly and opening into the compressor cylinder.
