Abstract

1. Rotary hydraulic device with variable cylinder of the volumetric pump type with coaxial stator and rotor (3) and with vanes (1) slinding axially in the rotor (3), the stator having at least one lower surface presenting fixed plane areas (18) and hollows (8), the said vanes following the said lower surface, the said hollows (8) being formed by movable elements (6) presenting axially a central plateau (15) forming the base of the hollow (8), and on both sides of this central plateau (15) a flank (16) with an inclined slope relative to this central plateau (15) each flank being laterally recessed with respect to the width of the central plateau (15) and being located between two fixed ramps (7) of the stator making the junction between the flank and the adjacent fixed plane area (18).
