<p>1. A piston machine, more particularly a hydraulically energized piston machine, having at least one cylinder (3) in which a piston (5; 5a; 5b) is guided for axial movement, the piston being connected by way of a connecting rod (7; 7a; 7b) to a crankshaft (4) or the like, the connecting rod (7; 7a; 7b) and the piston (5; 5a; 5b) being pivotally interconnected by way of a spherical bearing surface (9, 10, 11; 10a, 11; 9, 10b), characterised in that the connecting rod (7; 7a; 7b) has a spherical zone (12) which is disposed concentrically of the spherical bearing surface (9, 10, 11; 10a, 11; 9, 10b), engages sealingly in a recess (15) in the piston (5; 5a; 5b) and bounds therein a cavity (16) in fluid-conducting relationship with the cylinder chamber (6).</p> |
