Abstract (en)

[origin: ES8107365A1] The invention relates to a rotary electrohydraulic device of the volumetrical pump type having stator and rotor as well as vanes axially slidable in said rotor. According to the invention, the intermediary space between the rotor and the stator has an axial longitudinal circulary variable interval partly defined by a continuous stator bottom surface of a constant width, said slidable vanes coming to bear constantly and totally on said continuous bottom surface, which is single for a considered set of said vanes. The device according to the invention is mainly applicable as a brake or slackening means but can also work as a motor and a pump.
