Reciprocating piston engine, in particular a two-stage or multi-stage piston compressor, compressed air supply system, compressed air supply system and vehicle, in particular a passenger car with a compressed air supply system, method for assembling and operating a reciprocating piston

摘要

The invention relates to a reciprocating engine, in particular a one-, two- or multi-stage piston compressor or a one-, two- or multi-cylinder compressor, comprising: at least one cylinder and at least one respective piston associated with a cylinder, wherein in operation the piston along a radially aligned Cylinder axis is deflected in a cylinder stroke of the cylinder, an operable crankshaft with a crankshaft journal, which is arranged eccentrically to a shaft axis of the crankshaft, and a drive shaft coupling, which is designed for coupling a drive shaft for driving the crankshaft, at least one each for deflecting the at least one piston formed and extending along a connecting rod connecting rod, which is movable by means of the crankshaft journal. According to the invention it is provided that the crankshaft journal and / or the drive shaft coupling is aligned along an axially aligned shaft axis which is perpendicular to the radially oriented cylinder axis, and the connecting rod axis of the connecting rod is tilted against the radially oriented cylinder axis, so that Bearing clearance is reduced at least one connecting rod bearing.
