Abstract: In a radial piston pump, motor, transmission the deep diving or entering piston shoe is utilized and swingably borne in the pivot-bed of the radially reciprocating piston. Since deep diving piston shoes have large piston strokes, the shoes pivot in the pistons in large angles. Thereby a considerable force - portion of the load on the piston is transferred to the wall between the piston and the cylinder, whereby heretofore short pistons occasionally produced welding and sticking between the cylinder wall and the piston wall. The piston therefore receives radially extending portions, which may extend beyond the medial portion of the piston shoe and may even enter into the ring groove of the piston stroke actuator ring. Thereby a very long guidance of the piston on cylinder wall portions is obtained, which makes the application of effective pressure balancing pockets at correct location between piston wall and cylinder wall possible.
