A rotary roller motor is disclosed herein. The rotary roller motor is a four-stroke internal combustion engine, wherein the rotor “rolls” around the inside of the engine block. The rotor is a two-part rotor having an inner part with a shaft and an offset circular lobe, and an outer rotor fit around the lobe. Two barriers are provided around the rotor chamber, a compression/power barrier and an exhaust/intake barrier. The combustion chamber has a non-reversing compression barrier and a compression hold barrier regulating the combustion of gas.

A system includes an electric generator, a power electronics system, a first heat exchanger, and a second heat exchanger. The electric generator includes a turbine wheel, a rotor, and a stator. The turbine wheel is configured to receive process gas and rotate in response to expansion of the process gas flowing through the electric generator. The rotor is configured to rotate with the turbine wheel. The electric generator is configured to generate electrical power upon rotation of the rotor within the stator. The power electronics system is configured to receive the electrical power from the electric generator and convert the electrical power to specified power characteristics. A heat transfer fluid receives waste heat from the power electronics system through the first heat exchanger. The heat transfer fluid transfers the received waste heat to the process gas through the second heat exchanger.

An integrated combustor and stage one nozzle in a gas turbine includes a combustion chamber that receives premixed fuel and air from at least one fuel nozzle group at separate axial locations. The combustion chamber includes a liner and a transition piece that deliver hot combustion gas to the turbine. The stage one nozzle, the liner and the transition piece are integrated into a single part. At least one of the axial locations of the one or more fuel nozzle groups includes a plurality of small scale mixing devices that concentrate heat release and reduce flame length.

Rotary vane internal combustion engine comprises of two side-by-side rotors, placed in a cylindrical housing, wherein each rotor has at least two radial vanes rigidly attached to the rotor that form chambers for intake, compression, combustion, and exhaust. Each rotor alternately engages with a shaft by overrunning one-way clutches and is held from turning back, through the damper, mounted on a corresponding flywheel and forming a part of the flywheel assembly, which is rigidly attached on the shaft. The assembled rotors from the outside are rigidly closed by flanges on each of which is mounted at least one blade. The blades are positioned into formed cavities between the rotors and caps of the housing, thereby forming two cooling cavities through which coolant circulates around rotors through openings in the housing and through longitudinal grooves in the shaft. On the vanes are mounted cylindrical and conical seals, which remove the need for lubrication.

A gas compressor comprising a compressor main body including an approximately cylindrical rotor, a cylinder, a plurality of plate-like vanes formed to abut on the inner circumferential surface of the cylinder, and two side blocks is disclosed. A plurality of compression rooms is arranged inside the compressor main body so as to compress a medium and discharge the compressed high-pressure medium. A back-pressure-supplying groove supplies the back-pressure so as to project the vane toward the inner circumferential surface of the cylinder is arranged. An outer circumferential edge portion of the back-pressure-supplying groove is formed so as to increase a distance from a rotational center of the rotor toward the front side in the rotational direction of the rotor. A sectional surface area of a communication portion between the vane groove and the back-pressure-supplying groove increases until they are separated according to the rotation of the rotor.

The disclosure discloses a slide vane, a pump body assembly, a compressor and an air conditioner having the same. The pump body assembly includes a cylinder assembly, a flange portion, a rotating shaft and the slide vane. The flange portion is connected to the cylinder assembly, a working cavity is formed between the flange portion and the cylinder assembly, and an avoidance portion is provided on a surface, located in the working cavity, of the flange portion. A limiting structure is provided in an accommodation portion. The limiting structure is provided with an avoidance position in the accommodation portion, and at least part of the limiting structure is provided with a limiting position protruded out of a surface of the accommodation portion. Such a configuration avoids friction occurring between the head of the slide vane and the cavity wall of the working cavity.

An energy transfer machine includes a piston and cylinder. The piston can have a rocking motion as it enters and exits the cylinder, for example due to one being on a rotor and the other on a stator. The piston and cylinder form a primary chamber, and as they move relative to each other can form a seal separating the primary chamber into first and second sub-chambers which then unseals before the piston exits the cylinder. The first sub-chamber may reach a maximum geometric compression ratio, for example for the purpose of compression ignition, before the unsealing of the sub-chambers.
