Abstract
Abstract Apparatus for converting hydraulic or pneumatic energy into kinetic energy and vice versa. An inner element carrying sliding vanes is mounted in an outer element defining a plurality of recesses defining variable-volume chambers with the easier element and the vanes. The elements are relatively rotatable. Inlet and outlet conduits are provided in the inner element on each side of each vane. Means including a distributor valve put independent groups of said inlet and for outlet conduits in communication with a high-pressure fluid source or a low-pressure fluid source. Means connect the housings to a source of fluid under pressure.
