Rotary-piston electrohydraulic brake or motor - has sliding magnetic rotor blades bearing on deformable cycloidal stator surface

摘要

The intermediate space between the rotor (1) and stator (2) is circularly variable in the axial direction and is defined in part by a continuous stator base surface (6) of constant width. Blades (5) sliding axially on the rotor bear wholly and in a constant manner on the stator base (6) which is unique for a specific set of blades and pref. cycloidal. The magnetic field is created by one or more coils (7) and the blades (5) may be retained in their cavity by a permanent magnet (8). The stator surface is deformable so as to make rectilinear zones or spaces suited to the required function of the device.. The arrangement is applicable to electrohydraulic braking or decelerating systems, volumetric pumps or motors.
