Abstract:
A radial piston engine (2) with a cam ring (8), a cylinder block (18) disposed to rotate relative to the cam ring (8) around an axis of rotation (16), the said block having a plurality of cylinders (36) aligned in radial direction of the cylinder block (18), in each of which cylinders there is accommodated a slidable piston (44), which is braced via a roller (54, 96, 100) against the cam ring, wherein the roller is mounted on the piston to rotate around an axis of rotation (58) parallel to the axis of rotation (16) of the cylinder block (18) and, relative to its axis of rotation (58), is braced axially in the cylinder (36) via roller guides (60, 90, 92, 94, 98) disposed at its end faces, characterized in that the roller guides (60, 90, 92, 94, 98) are rigidly connected to the respective roller (54, 96, 100) with respect to sliding in piston displacement direction.
