Abstract
The present invention relates to a piston for hydraulic machines with axial positions, comprising a head connected to a stem which is extended along a longitudinal axis and forms a bottom arranged at the opposite end with respect to said head. The piston is further provided with at least one intake duct passing within it and having a first and a second end, which are mutually opposite, open respectively at the head and at the bottom. The distinctive aspect of the invention is that the piston also comprises at least one distribution duct passing within it, which has a first and a second end, which are mutually opposite, the first end of which is in fluid communication with the intake duct and the second end of which is open at the head, the piston being provided monolithically.
