  • Patent number: 11131236
    Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. Movement of the inlet-adjustment mechanism from the open position to the closed position is effective to shift the compressor's surge line to lower flow rates. The compressor includes a diffuser extending between an exducer of the compressor wheel and a volute for collecting pressurized air from the compressor. The diffuser is defined between first and second walls that diverge from each other in a radially outwardly direction through the diffuser. The divergent-wall diffuser enhances the shift of the surge line to lower flow rates when the inlet-adjustment mechanism is put in the closed position.

  • Patent number: 11125183
    Abstract: The invention described herein provides new devices suitable for effectively converting relatively low temperature differences into useful work (e.g., for generating electrical power), related systems, and methods of using and developing such devices/systems. The devices are characterized in, inter alia, comprising an at least partially enclosed moveable component (e.g., a piston), a closed pressurized gas system comprising sizeable void spaces, and a closed temperature modifying liquid system having portions that obtain temperature characteristics from two sources, which are alternatingly dispensed as droplets into the pressurized gas, creating a pressure/temperature difference in the gas which causes the moveable component to move back and forth along a stroke distance that does not include the void spaces, the pressure of the gas and liquid being at substantially balanced when the device is ready for operation.

  • Patent number: 11105296
    Abstract: The present invention features a hot air engine system designed to improve the overall efficiency of the engine. The engine features a mechanism for oscillating a piston cylinder such that the pivot point is at the bottom of the cylinder. This mechanism improves the overall efficiency of the engine by reducing the side forces that are produced when the back and forth motion of a piston is converted into rotational movement. To achieve this mechanism, a set of arms is attached to the piston cylinder and extend into the displacer chamber and are attached to the displacer. When the displacer oscillates during operation of the engine, the arms swing, and the cylinder rod swings in line with the arms, causing the cylinder rod to pivot at the bottom of the cylinder. This engine system runs on almost boiling water and can use industrial wastewater as a fuel source.
