Abstract:
The invention relates to a variable displacement hydraulic machine, in particular for a motor vehicle, said hydraulic machine comprising a rotating cylinder (10) including a series of axial pistons (12) connected to a first plate (14) axially located on one side of said cylinder within a substantially transverse plane, the slope of which can be controlled, so as to form a first controllable displacement for said machine, wherein said machine is characterized in that the cylinder (10) further comprises a second series of axial pistons (22) connected to a second plate (24), the slope of which is also controllable, said plate being axially located, relative to the first plate (14), on the other side of said cylinder so as to form a second controllable displacement for said machine.
