Abstract:
A two-stage reciprocating compressor is provided. The compressor includes a reversible motor that rotates a crankshaft. The crankshaft is connected to a piston by a mechanical system. The mechanical system drives the piston at a full stroke between a bottom position and a top dead center position when the motor is operated in a forward direction. The mechanical system drives the piston at a reduced stroke between an intermediate position and the top dead center position when the motor is operated in the reverse direction. The compressor also includes a control for selectively operating the motor in either the forward direction at a first preselected, fixed speed or in the reverse direction at a second preselected fixed speed.
