  • Patent number: 8286608
    Abstract: A sealing system for oscillating-piston engines that include two oscillating pistons that revolve together in a spherical housing. The pistons perform reciprocating oscillating movements in opposite directions about an oscillation axis perpendicular to the axis of revolution for the pistons. Guide members are provided on the pistons and engage at least one guide groove formed in the housing. Sealing elements are disposed on or in the vicinity of all moving edges surrounding working chambers and prechambers for the engine. The sealing elements seal all the gap regions present between machine parts displaced relative to one another by revolving and/or oscillating movements and not in direct contact. Sealing elements prevent excessive penetration of lubricating fluid into inlet and outlet openings in the housing.

    Abstract: A two-stroke opposite radial rotary-piston engine is proposed, comprising a block including sleeves, pairs of pistons disposed within the sleeves and oppositely movable, a power takeoff shaft, two parallel positioned rotors mounted thereon having an inner surface formed by a closed curved line. The rotors have concaved surface portions. Cross-like traverses are mounted, pair-wise spanning the pistons. The traverses are associated with engagement means, cooperating with the concaved portions. The engine comprises support bearings, coupled to the traverses. Support bearings include an external bushing, rolling over the rotor's inner surface, thereby impelling the rotor. The engagement means are mounted in the region of contact of the support bearings and rotors, thereby eliminating lateral force moment, extending the lifespan of the engine.

  • Patent number: 8261715
    Abstract: Internal combustion engine has intake with compression in piston/cylinders and combustion and exhaust in a turbine. Turbine assembly includes a rotor connected to an output shaft and has variable blades pivotally mounted to rotor. The output shaft is connected to a crankshaft that is connects to the pistons to synchronizes intake and compression with combustion and exhaust. While the rotor spins centrifugal force causes the blades to swivel outwardly. The blades swivel inboard of the rotor as the space between them and the turbine housing cam contour gradually decreases. After partial compression, air enters the turbine assembly's combustion and exhaust chamber. Once full compression is attained, combustion takes place initiating a power cycle causing the turbine to rotate. When the power cycle is completed, the inner cam contour forces the blades inboard and exhaust is cleared by the subsequent variable blade, facilitating the next combustion and exhaust cycle.

  • Publication number: 20100224165
    Abstract: The subject of the invention is a variable-volume rotary device with a housing (1) comprising an inner spherical cavity, inlet and exhaust ports and a bypass flow path. Within the housing (1) a rotary displacement member with spherical outer configurations capable of revolving around the center point of the spherical inner surface of the housing is mounted. Said rotary displacement member is equipped with a centrally disposed, disc-shaped partition (6) that forms a mutually isolated division in the spherical inner cavity of the housing (1) and has two pivot vanes (7, 8), splitting the housing cavity further into four isolated quadrants, the volume of which vary during gyration. Vanes (7, 8) are similar in shape to orange segments. Vanes (7, 8) are connected to opposing sides of and along the diameters of the central disc (6), and extend in mutually perpendicular planes, allowing for rotary movement.

  • Patent number: 7707987
    Abstract: A hydrogen G-cycle rotary vane internal combustion engine has a sodium vapor chamber transferring excess combustion heat into combustion chambers. An active water cooling system captures heat from the engine housing stator, rotor, and sliding vanes and transfers it back into the combustion cycle by premixing it with hydrogen to reduce peak combustion temperature and with an early an late stage combustion chamber injection to help transfer heat from the sodium vapor chamber, to control chamber temperature, and to increase chamber vapor pressure. A combustion chamber sealing system includes axial seals between the rotor and the stator, vane face seals, and toggling split vane seals between the outer perimeters of the sliding vanes and the stator. Sliding vanes reciprocate laterally in and out of the rotor assisted by a vane belting system. A thermal barrier coating minimizes heat transfer and thermal deformation. Solid lubricants provide high temperature lubrication and durability.
