<p>A piston (1) for piston machines, comprising a hollow body (3), open at least at its free end (7), with an axial hollow chamber (4) in which a filling piece (5) of a material specifically lighter than the material of the piston (1) and at least partially filling the latter is located, the filling piece (5) being fixed in the hollow chamber (4) and axially secured in the hollow chamber (4) by a securing element (8) arranged on the free end of the hollow body (3) and a spring (6) arranged between the securing element (8) and the filling piece (5), is to be so designed that the filling piece (5) is axially mounted and the axial securing and fixing is formed solely by the spring (6), which is pretensioned by the securing element (8) to such an extent that it acts against the filling piece (5) with a spring force which is greater than the maximum anticipated inertial forces of the filling piece acting against the spring (6) in operating service. …<IMAGE>… </p> |
