ABSTRACT:
A rotary machine with lenticular pistons and valves usable for internal and external combustion engines, expansion motors and pumps. A flat central stator housing is provided with two lateral cover housings. A plurality of rotating elements enclose the interior of the stator housing and rotate on stationary parallel shafts pivoted on bearings inside the cover housing. The parallel shafts are interconnected by a synchronizing gear train which causes the shafts to rotate in one direction and at the same angular speed. A cylindrical central cavity extends in the central stator housing throughout its entire thickness, and intersects smaller cylindrical equidistant surfaces distributed around the periphery. The cylindrical equidistant surfaces contact the cavity by a rotor-piston with lenticular cross section with associated valves also of lenticular cross section and surrounding the rotor-piston. The rotor-piston and rotor valves maintain continuous contact and form hermetic chambers of variable volumes.
