ABSTRACT:
The cylinder of a reciprocating compressor is provided with a flanged collar defining an annular recess adjacent the side walls of the cylinder bore disposed for entry of the piston skirt during the downstroke into the recess, compressing gas therein. Communication is provided between the recess and the space above the piston and cylinder head, increasing the initial pressure above the piston and causing greater pressure to be developed during the compression stroke. The result is an increase in the volumetric efficiency of the compressor.
