摘要： A rotary engine is provided for providing torque. The engine includes a housing, a stator, a crank shaft, a rotor and a pair of vanes. The housing has an inner wall with an elliptical profile with major and minor axes. The stator has an outer wall and a double ellipsoid profile corresponding to the major and minor axes. The crank shaft is disposed at a junction of the major and minor axes, rotating about a spin axis orthogonal to the profiles. The rotor has an annular circular profile disposed between the inner and outer walls. The rotor turns on the crank shaft. The vanes radially slide within the rotor as the crank shaft rotates and as the vanes turn within the inner and outer walls.

摘要： A rotary pump is provided for fluid transfer. The pump includes a planar housing, an elongated rotor, a pair of double-concave blades, fore and aft cover plates, and a gear box. The housing has a circular center cavity, and a pair of circular lateral cavities overlapping the center cavity and disposed along a longitudinal axis. The rotor is disposed on a rotor shaft along a rotation axis perpendicular to the longitudinal axis within the center cavity. The blades flank the rotor and are disposed within their corresponding lateral cavity and turn on corresponding blade shafts parallel to the rotor shaft. The fore and aft cover plates flank the housing along the rotation axis to cover the center and lateral cavities. The blades turn opposite from the rotor.

摘要： A rotary piston engine is provided that combines most of the advantages of an internal combustion engine with those of a turbine engine. The rotary piston engine improves on the existing internal combustion and turbine technology by achieving the same or better high end performance, while improving the efficiency during off-peak operations. The rotary piston engine includes an engine housing, at least one continuous cylinder doughnut, piston pedals, movable wall valves, at least one rotor and at least one point of rotation.

摘要： An internal combustion rotary engine that produces mechanical torque is provided. The engine includes an annular planar housing, a rotor, and first and second valves. The planar housing has a substantially circular annulus flanked by first and second cavities and an axial shaft disposed between the cavities. The rotor is disposed on the shaft and rotates within the annulus; The first and second valves are disposed within respective the cavities. Each valve has an arc wedge having outer convex surface and an inner concave surface, a shaft hole between and parallel to the surfaces along a rocking axis, and a pivot shaft that passes through the shaft hole to enable the wedge to rock back and forth within the cavity.

摘要： A pivoting flap valve is provided for an internal combustion rotary that produces mechanical torque. The engine includes an annular planar housing with a substantially circular annulus flanked by first and second cavities, an axial shaft, a rotor disposed on the shaft and rotating within the annulus. The valve is disposed within one cavity of said cavities and includes an arc wedge and a pivot shaft. The wedge has outer convex surface and an inner concave surface and a shaft hole between and parallel to the surfaces along a rocking axis. The pivot shaft passes through the shaft hole that enables the wedge to rock back and forth within the cavity in the annular planar housing without interference with the cam block. Each valve includes indents to pass around fore and aft circular wings on a rotor. The engine includes the housing, the rotor, first and second sparkplugs, first and second flap valves, an axial shaft and fore-and-aft covers. The housing includes a quadrilateral symmetry including a substantially circular annulus flanked by first and second cavities. The wings of the rotor intermittently block at least one port while the axial shaft rotates.

The housing includes a quadrilateral symmetry including a substantially circular annulus flanked by first and second cavities. The rotor has a cam block sandwiched between fore and aft circular wings. The sparkplugs are respectively accessible to the second cavities. The flap valves rock within the respective cavities and within the cam block. Each valve includes indents to pass around the wings. The fuel intake provides fuel to the cavities. The axial shaft rotates the rotor within the housing. Covers, each having a center orifice and a pair of ports exposed to ambient and respectively adjacent the first and second cavities. The wings intermittently block at least one port while the rotor rotates.
