Abstract
The compressor has a straight cylinder wholly confined within which are inlet valves, and reciprocatable discharge valves. One inlet valve is set in place by a centerbolt which can be turned by a wrench (or the like) to move the inlet valve to selected positions relative to its confronting discharge valve, whereby the volume of the clearance pocket is varied. The centerbolt mounted inlet valve, then, comprises an instrument for selectively varying the clearance pocket volume, obviating any need for any special clearance pocket varying devices or components.
