Abstract:
1. A multi-stage compressor for compressing gases comprising a low-pressure region and a high-pressure region, at least one screw-type compressor in the low-pressure region, at least one reciprocating piston compressor with two cylinders in the high-pressure region, a common engine for driving both the screw-type compressor and the reciprocating piston compressor, said engine having a crankshaft with a longitudinal axis that is substantially horizontal, said engine being disposed laterally next to the reciprocating piston compressor, wherein one double-acting piston is received in each of the cylinders, and the cylinders oppose each other by 180° in the high-pressure region with respective longitudinal axes of said cylinders extending substantially horizontally such that the reciprocating piston compressor is arranged in a boxer construction thereby neutralizing the forces of inertia from the reciprocating double-acting pistons during each crankshaft rotation.
