  • Publication number: 20140373527
    Abstract: The present invention provides a compressor powered by a pressurized gas, whether steam or another working fluid, and a system for extracting work using such as compressor. The pressurized gas may comprise a heated working fluid in a gaseous state, to displace a piston in an input circuit, which in turn displaces a piston in an output circuit, thereby compressing a compressible fluid or displacing an incompressible fluid. A purpose of the compressor is to convert waste heat, heat generated by the combustion of biomass or other fuels, or heat resulting from the concentration of solar energy into useful power, whether configured to produce compressed air or pump water, which can displace the electricity otherwise used for this purpose, or to produce electricity or motive force directly, through a hydraulic circuit. The system for extracting work does so by an output fluid which is compressed or pumped by a pressurized gas powered compressor.

A turbo supercharger (22), an exhaust bypass passage (36), a WGV (38) capable of switching the opening and closing of the exhaust bypass passage (36), and variable valve operating mechanisms (46, 48) capable of changing a valve overlap period are included. The valve overlap period is shortened so that the fresh air blow-through amount Gsca becomes equal to or smaller than a predetermined blow-through determination value Gjudge when the blow-through amount Gsca is larger than the blow-through determination value Gjudge.

  • Patent number: 8572960
    Abstract: A method for operating a compressor, which supplies an internal combustion engine that is assigned to the compressor at its output end with air compressed to a boost pressure, in which the boost pressure is reducible by releasing the compressed air at least partially via a pressure release valve. The air released via the pressure release valve is used for driving a compressor wheel of the compressor.

  • Publication number: 20130247558
    Abstract: The heat pump with a turbine-driven energy recovery system provides selectively cooled and/or heated air and recovers energy from refrigerant circulation. The heat pump includes a condenser for receiving refrigerant and condensing the refrigerant into a cooled liquid to release thermal energy therefrom. An evaporator receives the cooled liquid refrigerant and boils the refrigerant, the evaporator absorbing thermal energy to boil the refrigerant. A compressor circulates the refrigerant between the condenser and the evaporator, as is conventionally known. At least one turbine is positioned in a refrigerant flow path between the condenser and the evaporator, such that the at least one turbine is driven by the refrigerant circulating therebetween. At least one electrical generator is driven by the at least one turbine, the at least one generator being in electrical communication with the compressor for providing power thereto.

  • Publication number: 20130186084
    Abstract: Unique engines, air compressors, and pneumatically driven electrical generators are disclosed. The engine employs a rotor having a number of pistons slidably disposed within respective cylinder bores extending into the rotor periphery. As the rotor spins within a stator, each cylinder bore passes a combustion stage at which the piston is driven further into the rotor toward a bottom of the respective cylinder bore. Valves at the bottom of the cylinder discharge air that is compressed by this piston downstroke, and admit new intake air during an opposing upstroke. The unit thus operates as a self driven compressor, or engine-compressor combination, and the compressed air may be used to pneumatically drive a turbine of an electrical generator. A carbon splitter dissociates carbon and oxygen molecules from the carbon dioxide in the air downstream of the generator turbine, reducing the overall carbon dioxide output of the system.

  • Patent number: 8448440
    Abstract: A high order of thermal efficiency is achieved in a steam engine or steam expander having a piston clearance that approximates zero together with a negligible amount of compression, such that pressure in the clearance volume approximates ambient pressure, i.e. atmospheric or condenser pressure as the case may be at the end of the piston return stroke when the clearance is essentially zero and constitutes a new engine apparatus and Rankine operating cycle that can be referred to as “zero clearance with zero compression”. The steam admission valve assembly can be operated either automatically responsive to piston contact or by means of a cam shaft or electrically by means of a solenoid. A normally open exhaust valve permits residual steam to be exhausted through the piston return stroke, closed by the piston or cam then held closed by a fresh charge of steam.
