ABSTRACT:
A rotary hydraulic device of the displacement pump type having coaxial rotor and stator and vanes axially slidable in the rotor, the stator comprising at least one bottom surface formed with a variable number of deformations having rectilinear zones suitable for the operation on the recesses by the vanes. The recesses are made in movable elements of the stator such that the depth of the recesses can be made variable thus providing a device of variable capacity. The device is applicable to brakes and dampeners, as well as to engines and pumps.
