Rotary valve continuous flow expansible chamber dynamic and positive displacement rotary devices

A rotary piston continuous positive and dynamic displacement multiple purpose multiple fluid capable expansible chamber device comprising;

• a hollow annular cylinder housing with a smooth inner surface;
• a shaft having a longitudinal rotational axis aligned to a center of said cylinder housing;
• a rotor mounted for rotation with said shaft;
• at least one piston mounted radially on said rotor for circular movement in said housing when said rotor is rotated, each said piston having a conformably shaped outer peripheral surface in relation to said cylinder housing said piston having a lobe shape that angularly ramps as an inclined plane that gradually ramps from surface of said rotor to top of said piston;
• an intake port through said housing to allow a working fluid to enter said hollow housing;
• at least one isolating rotary crescent valve conformably shaped and associated with said respective piston and said hollow cylinder housing rotably connected at its axis to said rotary valve housing upstream and before said intake port the exterior perimeter of said rotary valve to be in rolling and sliding contact with said conformably shaped outer peripheral surface of said associated piston and said rotor following said conformably shaped surface;
• an external synchronizing control gear assembly attached to said rotary valve shaft in rotary contact with said rotary valve housing meshed with a similar gear of appropriate ratio that is attached to the shaft of said rotor piston assembly in rotable contact with said cylinder housing thus maintaining timing as well as significantly reducing wear on said components
• an accumulator area formed downstream of said rotary valve starting at the downstream side of said intake port and ending at
• an initial seal point, said initial seal point formed at a point that said piston seals with said smooth inner surface of said hollow cylinder at the downstream end of said accumulator area and of said intake port;
• an exhaust port for the discharge of said working fluid from said housing, said exhaust port located downstream of said initial seal point said accumulator area and said intake port on the periphery of said annular cylinder and after said piston and fluid's function is completed.
