Low-pressure compressor for gaseous media or ambient air with at least one piston-cylinder unit with piston rod coupled with crank arm driven by drive motor across reduction gear unit

摘要

The low-pressure compressor (10) is driven by a drive unit (16), which includes a drive motor (18) and a connected reduction gearbox, on the driven shaft (22) of which at least one crank arm (24) is arranged, restrained from rotation. The endface end of the cylinder (28) of the piston-cylinder unit, lying opposite the piston rod outlet side, is located in a frame (12), swivelable about an axis running parallel to the rotation axis of the driven shaft of the reduction gearbox (20).
