Hydraulic wheel II

A light weight fluid motor having reversed position vanes revolving with and inside a cylindrical plastic rotor means around an inclosed plastic stator;

• said rotor means being supported on a basic stationary metal spindle by frictionless bearing means;
• said spindle affixing interiorly said stator releasably;
• said spindle being adapted to cycle powering fluid in and out of said stator;
• said stator having at least two shallow arcuated fluid power chambers molded on its circumference;
• both sloping ends of said chambers communicating respectively with a pressure feeding first major manifold and a drooping pressure exhausting second major manifold;
• said slopes having fluid pressure control means;
• said major manifolds being in communications, through said spindle, with an exterior fluid power generating source;
• said rotor means comprising a cylindrical plastic housing box enclosing an annular plastic power ring in floating positive engagement with by releasable driving means;
• the bottom of said box having inserted reinforcing tubes, both ends of which communicating with the interior of said housing box;
• said power ring encircling the camming contour of said stator body with minimal operable clearance;
• the inside periphery of said power ring being copulated by a plurality of radially slidable plastic vanes in cooperative slots;
• said vanes being biased inwardly in liquid sealing contact with said camming contour by resilient means;
• a plurality of powering vanes, descending successively in the power chambers, being repulsed in sliding trajectory by incoming pressurized powering fluid;
• said powering vanes relaxing when approaching the ascending slopes to expel out drooping pressure fluid in said exhausting manifold;
• the other vanes, sliding idlingly on the major camming arcs, serving as liquid sealing barriers between the adjacent power chambers;
• said power ring having collecting chambers for the leak-off fluid between the vanes and their slots;
• two annular plastic seal plates serving as, constant lubricated contact, side walls for said power chambers;
• said seal plates being positioned as pistons in cooperative pressure chambers molded in both end plates of said housing box;
• said seal plates overlapping partially both faces of said power ring and stator body with clasping force supplied by resilient and fluid pressure means inside said pressure chambers;
• said seal plates being in loose positive engagement with both housing end plates by releasable driving means;
• said seal plates rotating with the housing and the power ring;
• said seal plates sliding on a portion of both faces of said stator body;
• said pressure means inside the pressure chambers communicating with said power chambers through feeding minor manifolds embedded in the plastic mass of said stator body;
• said minor manifolds communicating with said major manifolds;
• said minor manifolds feeding also said friction relaxing means between the rubbed faces of said seal plates and stator body;
• uni-directional valves being interposed between the minor and the major manifolds to control flow directions to said friction relaxing means;
• said wheel motor having equal efficiency in both directions of rotation and capable of dynamic braking;
• a scavenging system means for exiting interior leak-off fluid out of said motor;
• said leak-off lubricating the interior moving parts;
• sealing means between said spindle and motor housing preventing exterior spoilage of said leak-off, being recuperable by recycling means.
