Abstract

An air compressor, which is embodied as a single or multi-cylinder/piston compressor, and which is driven by gear wheels. The drive gear or pinion of the air compressor is disposed on the air compressor crankshaft and meshes with a gear wheel on the camshaft of an internal combustion engine. Provided on the periphery of the air compressor pinion is, for a single cylinder/piston compressor, one interval having an enlarged tooth gauge, and for a multi-cylinder/piston compressor, several such intervals, the number of which corresponds to the number of times the tangential force passes through zero during one air compressor crankshaft revolution, with the centers of the intervals being coordinated with the respective top dead center position of the air compressor piston.
