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.

Abstract: For the combined intake section of a compressed-air generating system comprising an air compressor and an air dryer, the use of an additional muffler is proposed for an air-spring system that is employed mainly in passenger vehicles. This muffler is installed directly in a rubber hose leading to the atmosphere. Both air for the air compressor is sucked in and air for regeneration of the air dryer is discharged to the atmosphere through this muffler. The muffler has a simple construction, because of the fact that a damping insert, composed of a roll of noise-reducing knitted fabric, is pushed into the rubber hose, and throttling of the air stream is additionally provided at the point of the port to the atmosphere.
