Abstract
An apparatus and a method for controlling the capacity of a reciprocating compressor by altering the effective stroke length of the working piston of the compressor is disclosed. The working piston of the compressor has a piston opening extending through the top surface thereof. A bypass piston having a cylindrical portion sized to block the piston opening and a reduced cross-sectional portion designed to allow gas to flow through the piston opening is provided. By adjusting the position of the bypass piston the effective stroke length of the working piston may be controlled to allow modulating compressor operation.
