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.

Abstract: The invention relates to an axial piston machine in which pistons carry out a stroke movement in cylinders and in which the pistons have a seal ring receptacle for a seal ring. In order to improve robustness, wear resistance, friction and stick-slip behavior, according to the invention, the seal ring is spherical, wherein the curvature radius of the seal ring, which is spherical in regions, substantially corresponds to half the diameter of the cylinder inner wall.
