Radial reciprocating engine having a ball piston

Abstract

The invention relates to a radial reciprocating engine (1) having cylinders (5) arranged in a cylinder carrier (16) and a piston element (21) arranged in each cylinder (5) that is connected to a guide element (22), wherein the guide element (22) runs on a slide surface (14), whereby a stroke movement is imposed on the piston element (21). Since the piston element (21) is spherical at least in the region of the piston element (21) which seals the inner walls (51) of the cylinder (5) during the stroke movements, a linear seal is created, which enables a more compact design in comparison to radial pumps with cylindrical piston elements.

1 . Radial reciprocating engine comprising:
 cylinders arranged in a cylinder carrier and a ball piston arranged in each cylinder;   the ball piston rigidly connected to a guide element via a connecting element and the guide element rigidly connected to the connecting element;   wherein the guide element runs on a slide surface;   wherein a stroke movement is imposed on the ball piston;   wherein the ball piston is spherical at least in a region of the ball piston which seals an inner walls of the cylinder during the stroke movement; and   wherein the region of the ball piston which seals the inner wall of the cylinder during the stroke movement comprises a symmetrical spherical zone.
