Radial cylinder hydraulic machine with a distributor each cylinder

A hydraulic machine comprising:

• a machine body including a plurality of cylinder-piston units including:
• oscillating radial cylinders;
• and
• pistons which are slidable on a crankshaft or with a cam, or on interposed members concentric to the crankshaft, and realize a reciprocating motion in the oscillating radial cylinders;
• and
• a single distributor body formed, on each cylinder, in a surface of distribution concentric or corresponding to a surface of oscillation of the respective cylinder,
• wherein said oscillating radial cylinders are put in contact with the surface of distribution on which each corresponding distributor body is placed, separate from the machine body and housed in a seat in the machine body, or part fixed to the machine body, of the hydraulic machine,
• wherein each distributor body is mobile in its seat under the action of a liquid pressure acting on a back surface of said distributor body to be pressed against the surface of distribution of the oscillating radial cylinder subject to the distribution of the corresponding distributor body, and
• wherein each distributor body comprises:
• a plurality of shaped ducts formed in the back surface of the distributor body;
• and
• a plurality of ports of distribution forming a passage for the liquid from the shaped ducts to a slit in the respective cylinder.
