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

A reciprocating piston machine includes a first cylinder and a first piston assigned to the first cylinder and a second piston assigned to the first cylinder or a second cylinder. The reciprocating piston machine further includes a crankshaft having an eccentric crankshaft journal and a drive shaft coupling configured for coupling a drive shaft of a drive motor for driving the crankshaft, a first connecting rod configured to deflect the first piston and configured to be moved by the eccentric crankshaft journal, and a second connecting rod configured to deflect the second piston and configured to be moved by a bearing pin. The reciprocating piston machine additionally includes at least one of a first elastomer element arranged between the bearing pin and the first connecting rod and a second elastomer element arranged between the bearing pin and the second connecting rod.
