ABSTRACT:
A dry-running reciprocating compressor which has a drive mechanism with a crankcase, in which at least one crankshaft is mounted to rotate in bearings. The drive mechanism is operatively connected with at least one piston-cylinder arrangement of the compressor to compress air to the desired compression pressure. The intake air to be compressed is used for interior cooling of the drive mechanism, and for this purpose, the intake air is conducted through a filter into the interior of the crankcase. For specific cooling of especially critical parts and areas of the components and units in the interior of the crankcase, additional air conducting devices, such as air baffles, fins or the like can be provided. Preferably, the reciprocating compressor has three stages.
