Abstract: A rotor can comprise a body having arcuate voids each presenting away from a rotation axis and, for each void, a vane. The vane is mounted to the body for pivotal movement between retracted and extended positions; is adapted to sweep the void in the manner in which a piston sweeps a cylinder during movement between the positions; and terminates in a tip. A stator defines the rotation axis; and has an annular surface which, in use, is swept by the tips during rotation of the body. The surface is positioned such that, in each rotation, each vane cycles between its extended and retracted positions. A sealing arrangement defines a pair of ports and, in combination with the rotor and stator, defines, in use, chambers that increase in volume when in communication with one of the ports and that decrease in volume when in communication with the other of the ports.

Abstract: A cam ring fluid machine, a rotary cam ring fluid machine has a casing, a flange in the casing, a stator in the casing, a rotor cam ring in the stator, a fixed axis in the rotor cam ring, and a vane in the vane groove of the fixed axis. A fluid chamber is formed with the inner circumferential surface of the rotor cam ring, the outer circumferential surface of the fixed axis, the vane, and the flange. When the rotor cam ring rotates, the volume of the fluid chamber increases or decreases.

Abstract: A rotary engine has a rotor that has rockers pivoting in chambers. As each rocker pivots, it rotates an outer crankshaft. Each outer crankshaft has a spur gear that engages a stationary ring gear. Spur gear rotation causes the gears and the outer crankshafts to revolve around the ring gear. This cause the rotor to rotate. As the rotor rotates, successive chambers are positioned at the intake, compression, ignition, and exhaust positions. Igniting the fuel in the ignition position pushes the rocker inward to rotate the outer crankshaft associated with that rocker to cause the rotor to rotate.

Abstract: Embodiments of rotary vane engines include rotors that rotate about an axis of rotation. The rotors can be moved in directions substantially perpendicular to the axis of rotation to vary expansion and/or compression ratios of the rotary vane engines. The ability to vary the expansion and/or compression ratios can facilitate optimization of the performance of the rotary vane engines as operating conditions vary.

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.

Abstract: An internal combustion rotary engine (1) comprises an engine casing (300) in which is rotatably mounted a cylindrical rotor assembly (2) co-axially fixed to a drive shaft (6). The rotor (3) receives a plurality of reciprocating vanes (9, 10, 11) in a staggered and radial arrangement. These vanes (9, 10, 11) are connected to cam axels (13, 14, 15) which in turn impart and control their reciprocating movements through a slidable engagement with cam pathways. The reciprocating movements of the vanes define the working chambers of the engine as the rotor rotates.

The vanes contain extended pins that move in a pin channel for controlling the sliding motion of the vane. Fuel is mixed by incorporating air turbulence generators at or near the intake region. The intake and exhaust regions of the engine also incorporate a wave pumping mechanism for injecting and scavenging air from the main chamber cells and the vane slits. The compression ratio of the engine may be varied while the engine is in operation, and the engine geometry provides for an extended temporal duration at about peak compression. The engine is insulated by using segmented ceramic inserts on the stator and rotor surfaces.

Abstract: A rotary machine of the type which includes a rotor rotatably mounted in a stator and carrying vanes mounted for radial movement to cooperate with the inner surface of the stator to, for example, compress a gas drawn into the stator housing through an inlet port. The necessary radial movement of the vanes during rotation of the rotor is accomplished by means of cam followers associated with the vanes which ride on stationary cam surfaces. The cam surfaces are round and have their axes positioned eccentrically with respect to the axis of rotation of the rotor. Tension springs draw the vanes radially inwardly of the rotor so that the cam followers are held in contact with the cam surfaces. This provides positive vane control and prevents vane lifting while minimizing contact between the vane tips and the stator inner surface.
