Abstract
A reciprocating-piston machine, in particular a two-stage or multi-stage piston compressor, includes: a first connecting rod for deflecting a first piston and which has a connecting-rod eye, the first connecting rod being a drive connecting rod; a second connecting rod for deflecting a second piston and which has at least one further connecting-rod eye, the second connecting rod being a follower connecting rod; a coupling element which extends through the connecting-rod eye and the at least one further connecting-rod eye and about which the first connecting rod and the second connecting rod are rotationally movable relative to one another; a coupling bearing element arranged between the coupling element and a connecting-rod eye inner surface of the connecting-rod eye; and a damping element with elastic damping action arranged in a damping annular chamber between the coupling bearing element and the connecting-rod eye inner surface of the connecting-rod eye.
