Abstract
A hydraulic machine having each pair formed by a piston and a housing defines between the piston and the housing a first chamber and a second chamber which are separate from one another, the cylinder block and the distributor each have a plurality of inner ducts defining a first set of ducts and a second set of ducts. The sets of ducts opening open onto the interface between the distributor and the cylinder block at two separate radii with respect to the main axis and being are suitable for respectively supplying the first chambers and the second chambers.

A hydraulic machine comprising:
- a first assembly and a second assembly, rotationally movable with respect to one another about a main axis,
- the first assembly comprising a casing and a multilobe cam,
- the second assembly comprising a shaft, a cylinder block, the cylinder block having a plurality of housings in which pistons slide, each piston being positioned in a housing,
- the hydraulic machine further comprising a distributor suitable for providing the supply and discharge of fluid, the distributor bearing against the cylinder block along an interface extending radially with respect to the main axis,
- wherein
- each pair formed by a piston and a housing defines between the piston and the housing a first chamber and a second chamber which are separate from one another,
- the cylinder block and the distributor each have a plurality of inner ducts defining a first set of ducts and a second set of ducts, said sets of ducts opening onto the interface between the distributor and the cylinder block at two separate radii with respect to the main axis and being suitable for respectively supplying the first chambers and the second chambers.
