The invention relates to a dry-running piston compressor, in particular for rail vehicles. Said compressor comprises a crankcase ( 3 ) for a crankshaft ( 15 ) that is rotatably mounted in said crankcase, the latter being provided with at least one pot-type cylinder ( 4 a -4 c) comprising a corresponding internal piston ( 12 a , 12 e). According to the invention, the crankshaft ( 15 ) is connected to one end of a connecting rod ( 14 a , 14 c) by means of a connecting rod hearing ( 16 ), which forms the first hearing point, in order to convert the rotational displacement into a linear displacement for the piston ( 12 a , 12 c) that is mounted at the other end of the connecting rod ( 14 a , 14 c) by means of a piston pin bearing ( 17 ), which forms the second bearing point. At least one lubricating nipple ( 18 a , 18 c) is mounted on the exterior of each connecting rod ( 14 a , 14 c) for relubricating the bearing point(s). A corresponding internal lubrication channel ( 22 ) runs from said nipple and discharges onto the connecting rod ( 16 ) and/or onto the piston pin bearing ( 17 ). |
