    Abstract: A block sealing of a rotary combustion engine having a rotating block with radially located cylinders and pistons and an outside stationary case is disclosed. Transverse and/or lateral sealings located in the stationary case fit tight to an outer surface of the block. In circular grooves, a lateral sealing of radius sealing strips with springs situated between adjacent transverse sealing strips placed in transverse grooves is located. Couplings with notches and pressure springs are located in bores of the stationary case for inserting radius sealing strips and transverse sealing strips. The radius sealing strip is provided with a cut-out for interlocking of a stop connected with the stationary case. In the side of the radius sealing strip, a longitudinal groove in which a flexible sealing element and/or transverse sealing strip is made, and at its side, it is provided with a groove in which another flexible sealing element is located.

    Abstract: A rotary-piston internal-combustion engine comprises a rotating block with three radially situated cylinders with pistons and an outside placed stationary case with two intake ports and two exhaust ports. Between the rotating block and the stationary case there are sealing parts and connecting rods, connected to one crank pin of a crankshaft. Between the crankshaft and the rotating block there is gearing for three times higher revolutions of the crankshaft in the opposite direction with respect to the rotating block. In the stationary case there are at least two spark plugs placed on the opposite sides. The bore of cylinders is 2 to 3.5 times higher than the stroke of pistons and all sealing parts with pressure springs that seal spaces of cylinders to the outer stationary case are placed in cavities in the stationary case.

    Abstract: A cylinder head for a four-stroke combustion engine includes at least one inlet conduit having a valve and/or slide valve and at least one exhaust conduit situated in the cylinder head. The inlet conduit and the exhaust conduit connect into a single main conduit. The main conduit has an orifice having the shape of an annulus, the axis of which is aligned with the main axis of the cylinder. The orifice of the main conduit is provided with an interior valve seat and an exterior valve seat, on which, in the closed position, is seated a ring-shaped plate of the sole lifting valve. The lifting valve has at least one stem. The exhaust conduit of the cylinder head is directly interconnected to the exhaust branch and includes no valve gear and/or slide valve gear. The size of the orifice flow cross-section area corresponds to the sum of flow cross-sectional areas around and inside the annular plate. A space is provided in an interior area adjacent to the valve seat for a spark plug and/or an injection nozzle.

    Abstract: A piston internal combustion engine with generator has two cylinders and cylinder heads and pistons with connecting rods and two crankshafts which are connected by gears with a ratio of 1:−1 (with opposite direction of rotation). The first crankshaft with the gear is mounted parallel to the second crankshaft with the second gear in one engine case such, that the gears engage. The first crankshaft is coupled to the first generator rotor and the second crankshaft is coupled to the second generator rotor or the flywheel. The moment of inertia of the first crankshaft assembly with the first gear and the first generator rotor is equal to the moment of inertia of the second crankshaft assembly with the second gear and the second generator rotor or flywheel. The cylinders with the pistons and are positioned perpendicularly to the plane of symmetry between the crankshafts, with the axes of the pair of cylinders lying in a plane with the both pistons being at the top dead center simultaneously.

    Abstract: A cylinder head for an internal combustion engine has a body, a rigid center spacedly surrounded by the body, an annular outer valve seat on the body, and an annular inner valve seat on the center. A ring-shaped valve has an outer seat face and an inner seat face and is displaceable along an axis into a closed position bearing on the outer valve seat with the outer seat face and on the inner valve seat with the inner seat face. The inner valve seat or outer valve seat is slidable axially. A seal member set in a groove in the center or in the body engages the one slidable seat. At least one biasing member connected to the one slidable valve seat urges same toward the ring-shaped valve.
