<p>The subject deals with a protection against axial distortion of the hydraulic engine piston (2) in the piston-cylinder assembly of the radial-piston hydraulic machine, where the cylinder roller (3) features a throughole (8) which holds from the end of the specified roller a cylinder shaped inserted piece adapter (9, 9') of the wedge piece (10, 10'). The wedge piece (10, 10') is on its side which is nearest to the internal cylinder (1) surface (11), featuring a guiding groove (12; 26), which grabs the head (14; 17; 25) of the protective element (12, 18, 22).</p> |
