Abstract
An articulated air vane air or hydraulic motor has a rotor core disposed coaxially in a cylindrical housing, with a plurality of articulating vanes that seat in axial sockets or slots in the rotor core. A crescent shaped insert defines a cam surface in the chamber between the housing and the core. Inlet and exhaust ports are formed either in the housing cylinder or in the end plates. Vane wear is significantly reduced and injected lubricant is not required. The vanes can be generally P-shaped in cross section, with stop structure to limit the articulating motion.
