Abstract
The invention relates to a dry-running piston compressor, in particular for rail vehicles. Said compressor comprises a crankcase () for a crankshaft () that is rotatably mounted in said crankcase, the latter being provided with at least one pot-type cylinder () comprising a corresponding internal piston (). According to the invention, the crankshaft () is connected to one end of a connecting rod () by means of a connecting rod hearing (), which forms the first hearing point, in order to convert the rotational displacement into a linear displacement for the piston () that is mounted at the other end of the connecting rod () by means of a piston pin bearing (), which forms the second bearing point. At least one lubricating nipple () is mounted on the exterior of each connecting rod () for relubricating the bearing point(s). A corresponding internal lubrication channel () runs from said nipple and discharges onto the connecting rod () and/or onto the piston pin bearing ().
