Abstract (en)

[origin: EP2426336A2] The piston (1) has two pivot bearings (55, 65) for piovtably supporting a connecting rod (5, 6) at the piston around connecting rod pivot axes (Y5, Y6). The pivot axes run parallel to each other and laterally arranged at distance from each other. The pivot bearings are provided at a bearing element e.g. disk or ring, which is pivotably supported at the piston around a bearing pivot axis (Y7) that runs parallel to the rod pivot axes. The bearing pivot axis lies in center of a line (G) that connects the rod pivot axes in a pivot plane (E1). An independent claim is also included for a double crankshaft piston machine including a piston-cylinder unit.
