ABSTRACT:
A piston compressor has a cylinder including a traveling piston sealed therein. A drive motor acts on a crankshaft, a drive shaft thereof being received by a bore of the crankshaft. A connecting rod provides for articulated connection of a crankshaft-journal of the crankshaft with the piston in a connecting rod bearing. The connecting rod is disposed relative to the drive shaft in an angled orientation that counteracts bowing deflection of the drive shaft that occurs during operation to protect against undesirable wear of the piston seal and of the connecting rod bearing.
