  • Patent number: 4700613
    Abstract: The invention relates to a hydraulic motor, which comprises a surrounding frame casing; an internal cylinder block with radially arranged cylinders and a stationary axle of the hydraulic motor attached thereto; pistons reciprocating in the cylinders and bearing the inner surface of the frame casing, which surface is formed as a running surface guiding the movement of the pistons; a fluid distributor mounted around the axle to rotate together with the frame casing, for the distribution of the hydraulic fluid into cylinder chambers and away therefrom via openings provided in the cylinder block; and feed and exhaust channels for the hydraulic fluid. The object of the invention is to improve such a hydraulic motor by compensating, without complicated balancing elements, the force caused by the pressurized hydraulic fluid and separating the fluid distributor and the cylinder block.
