ABSTRACT:
In a radial piston engine having pistons bearing against the circumference of an eccentric, which pistons execute a swivelling motion upon the rotational motion of the eccentric and are in engagement with a guide body, which bears on the radially outer end by a radially outwardly convex spherical-annular bearing face against a concave spherical-annular bearing face in the housing or cylinder cover. To attain complete piston relief, the bearing arrangement is designed such that the guide body (2) is provided with an upper end face (8) which is acted on by the pressure medium over a hydraulically effective plane (de) extending perpendicularly to the longitudinal axis of the guide body (2). The hydraulically effective plane lies in the area of the bearing face (5) on the housing (6) or intersects the face for all swivelling positions of the piston (3).
