    摘要： A near adiabatic engine has four stages in a cycle: (1) a means of adiabatically expanding the working fluid during the downstroke from a high pressure/temperature level to a low level; (2) a means of cooling the working fluid at Bottom Dead Center (BDC); (3) a means of adiabatically compressing that fluid from a low pressure/temperature level at BDC to the higher level at Top Dead Center (TDC); and finally, (4) a means of passing that working fluid back to the high pressure/temperature source in a balanced pressure environment so as to minimize the resistance of that flow. This disclosure teaches the means of achieving (2) and (3) as follows: (2) a means is disclosed of BDC cooling of the expanded working fluid in the working chamber, and (3) a means is disclosed of adiabatically compressing the working fluid into the pump chamber before cycling the fluid.

    摘要： A device for compressing a gaseous fluid includes a first chamber thermally coupled with a hot source, a second chamber thermally coupled with a cold source, a movable piston moved by a rod, and a regenerating exchanger establishing fluid communication between the first and second chambers. The rod is arranged in a cylindrical socket and guided in axial translation by a linear guiding system such as to guide the piston without contact relative to the sleeve. A sealing ring attached to the cylindrical socket surrounds the rod with a very low radial clearance, in order to limit the passage of the gaseous fluid along the mobile rod. Also disclosed is an integral cold casing having machined boreholes, a thermal screen in the hot casing, and a self-driving system with a resilient return means.

    摘要： A method and apparatus for conversion of heat into liquid fluid power includes at least two hydropneumatic (hp) accumulators, each having a gas reservoir and a liquid reservoir therein separated by a movable separator. Liquid added to a liquid reservoir of a first accumulator causes gas compression in the gas reservoir of the accumulator. Gas is conducted from the first accumulator through a heat exchanger and into a gas reservoir of a second accumulator. Expansion of the gas in the second accumulator causes working liquid to be expelled from the second accumulator. After expansion of the gas in the second accumulator, working liquid is added to the liquid reservoir of the second accumulator gas is conducted through a cooling heat exchanger to the gas reservoir of the first accumulator, causing working liquid to be expelled. The fluid power produced through the expelled working liquid is stored or utilized to operate hydraulic devices.

    摘要： A rotary vane engine system for using exhaust heat energy of a fuel-based heat engine. The heat engine includes a crankshaft being driven by a combustion cycle, and the heat engine generates exhaust gases by combustion. The system comprises an independent air system, wherein the independent air system contains air separate to the exhaust gases. A heat exchanger system is provided for transferring exhaust heat energy from the exhaust gases to the air contained in the independent air system to generate pressurized air. A rotary vane engine is also provided having a housing, a rotor contained within the housing and coupled to the crankshaft of the heat engine, and a plurality of vanes extending radially from the rotor. The pressurized air is expanded within the rotary vane engine for rotation of the rotor thereby providing drive to the crankshaft of the heat engine.

    摘要： A free piston Stirling cycle machine is illustrated by an engine that utilizes an axially movable displacer subjected to working gas pressures. A primary hydraulic circuit hydrostatically couples a displacer drive rod integral with the displacer to a counterbalance illustrated in the form of a scotch yoke. The counterbalance stabilizes and controls the Stirling cycle engine by constraining the displacer's reciprocating axial motion in a repetitive pattern. A throttling valve interposed in the primary hydraulic fluid circuit is used to adjustably resist displacer motion as required by engine operating conditions. A secondary hydraulic circuit is provided together with a bellows assembly between the working gas and power pistons to convert changes in working gas pressure to usable power output in the form of pumped hydraulic fluid.

    摘要： The present invention relates to a Stirling engine which includes a first wall member forming a part of a vessel, a second wall member forming a part of the vessel, a third wall member forming a part of the vessel which is transformable and at the same time the transformation of which can change the positional relationship of the second wall member relative to the first wall member, a working fluid sealed in the vessel, a heater for heating the working fluid in the vessel through the first wall member, a cooler for cooling the working fluid in the vessel through the second wall member, a regenerator and a mechanical device which is driven by the working fluid when the working fluid is moved relative to the second wall member to change the pressure so that a part of the heat generated by the heater and transferred to the working fluid is used for driving the mechanical device. The first and second wall members are not connected by a bolt and a nut as in the prior art, but are connected to each other, for example, by bellows. Therefore, according to the present invention, the heat lost from the first wall member to the second wall member is reduced to enhance the thernal efficiency of the Stirling engine.
