ABSTRACT:
A clearance pocket having a housing attached to a cylinder of the compressor. In one embodiment, in which the housing has a sidewall and a distal wall and includes a clearance chamber with a passageway extending between the cylinder head and the clearance chamber, the pocket also has a piston movably located in the clearance chamber in slidably sealing engagement with the interior sidewall of the housing, and means for providing fluidic communication between the cylinder head and that portion of the clearance chamber between the piston and the distal wall of the housing. In another embodiment, in which the housing also includes a second clearance chamber with a second passageway extending between the first and second clearance chambers, the pocket also has a second piston movably located in the second clearance chamber in slidably sealing engagement with the interior wall of the housing; means for fixedly separating the first piston and the second piston so that they move freely in unison means for providing fluidic communication between the cylinder head and that portion of the first clearance chamber between the first piston and the effectively closed second passageway; and controllable means for establishing fluidic communication between that portion of the second clearance chamber between the second piston and the effectively closed second passageway and that portion of the clearance chamber between the second piston and the distal wall of the housing.
