Abstract
A rotary vane hydraulic element, body of which, confining internal hydraulic space in the shape of toroid with the rotation axis X-X, is divided by plane (A-A), that crosses the space perpendicularly to the rotation axis (X-X) and in case of the space of circular toroid shape (torus)—by plane (A-A) that crosses the space perpendicularly to the rotation axis (X-X) and the center point of the circle delimiting the space, into the movable part (1.1)—the rotor and the stationary part (1.2)—the stator. Both parts of the body are bound by two thrust rings (1.7a) and (1.7b), that are fastened concentrically on the both opposite sides of the hydraulic space each to the respective edge of one body part and that overlap the other body part radially, to create in conjunction with both body parts two concentric slewing bearings.
