  • Patent number: 10018110
    Abstract: The inventive rotary engine comprises a cylindrical chamber inside a casing wherein there is a concentric rotatable power shaft and a rotatable asymmetric main wheel mounted eccentrically enough as such to avoid contact with the wall of cylindrical chamber. Additionally two bars traversing the main wheel radially further having a wiping contact with the cylindrical chamber wherein one bar is fixed with power shaft and other bar is hinged with said power shaft. A combustion process is in action within a demarcated combustion chamber whereby the combustion chamber rotatably travels from a bottom dead volume to a top dead volume and hence a power, generated during this path of rotational travel, is subsequently available for delivery at the concentric power shaft.

  • Patent number: 10012142
    Abstract: A rotary internal combustion engine includes a cylinder seat and a power wheel. The cylinder seat has a circular cylinder, at least one first explosion chamber disposed on a cylinder wall, and an ignition system, a fuel supply system, a compression assembly, an exhaust and an intake installed thereon for each respective first explosion chamber. The power wheel is slidably coupled to the circular cylinder, and has at least one compression chamber and a second explosion chamber disposed adjacent thereto and when rotated provides connection to the first explosion chamber. As a result of rotation of the power wheel, air and fuel gas are compressed in the compression chamber, collected into the first and second explosion chambers, and then ignited by the ignition system to produce a high explosive yield, so that the power wheel is rotated constantly in a single direction to provide high-efficiency kinetic energy.

  • Patent number: 10006414
    Abstract: In accordance with the present invention, condensed water generated upstream of a compressor can be caused to flow into a groove 44, and temporarily accumulated therein. The condensed water flowing into the groove 44 moves to a lower portion in a gravity direction (that is, to an ABV 38-side) in the groove 44. When the ABV 38 is opened, the condensed water accumulated in the groove 44 is blown away to a center portion of an inlet 46 on a flow of a return gas, and, together with an intake gas flowing through the center portion, the condensed water flows into a compressor 20 from a center portion 42b of a front end surface of an impeller 42. Since the center portion 42b has a lower circumferential speed than that of an outer peripheral portion 42a, occurrence of erosion by contact with the condensed water can be suppressed as compared to the outer peripheral portion 42a.

  • Patent number: 10001011
    Abstract: Axially protruding and centrally cool able pistons rotate within a cylindrical main chamber. Each piston is individually kinetically linked to a flywheel. As the pistons are individually accelerated and decelerated along their continuous rotating path, rotating volumes between them angularly expand and contract. Inlets and outlets communicate fluid in correspondence with expansion and contraction phases of the rotating volumes. A low number of moving parts, area sealed volumes, no valves, balanced mass forces, smooth rotation and short force transmission paths between opposing mass forces provide for lightweight construction and high rotational speeds. Radial sliding secondary pistons of the kinetic linkage modulate secondary rotating volumes adjacent the main chamber for a dual stage thermodynamically efficient engine operation with intermittent fluid cooling or heating.
