Reciprocating-piston machine, compressed-air supply installation, compressed-air supply system, and vehicle

A reciprocating-piston machine, having:

• at least one first cylinder and at least one first piston assigned to the first cylinder;
• at least one second cylinder and at least one second piston assigned to the second cylinder, wherein, during operation, the first piston and the second piston are deflected in a respective cylinder displacement chamber of the respective first cylinder and the second cylinder,
• a crankshaft which, during operation, can be driven and which has an eccentric crankshaft journal and a drive shaft coupling designed for the coupling of a drive shaft of a drive motor for driving the crankshaft,
• a first connecting rod configured to deflect the first piston,
• a second connecting rod configured to deflect the second piston, and
• a bearing pin about which the first and second connecting rod are rotationally movable,
• wherein the first connecting rod is mounted by at least one first connecting-rod bearing directly on the crankshaft journal and is movable by the eccentric crankshaft journal, and the second connecting rod is movable by the bearing pin, and
• wherein, between the bearing pin and at least one of the connecting rods, there is arranged at least one second connecting-rod bearing and at least one elastomer element that serves for the elastically dampened and/or resilient mounting of the at least one second connecting-rod bearing.
