摘要： A four-process cycle is disclosed for a Vuilleumier heat pump that has mechatronically-controlled displacers. Vuilleumier heat pumps that use a crank to drive the displacers have been previously developed. However, mechatronic controls provides a greater degree of freedom to control the displacers. The four-process cycle provides a higher coefficient of performance than prior cycles in the crank-driven Vuilleumier heat pump and those previously disclosed for a mechatronically-driven Vuilleumier heat pump.

摘要： In accordance with an embodiment of the invention, there is provided a device for generating electrical energy using a thermal cycle of a working gas. The device comprises at least one piston movably mounted in a container to form a working chamber between the at least one piston and the container, the working chamber containing the working gas performing the thermal cycle. An electrical circuit is mounted stationary relative to the container, the electrical circuit being electromagnetically coupled to provide a motive force to the at least one piston. An electronic power converter is electrically connected to the electrical circuit and to an electrical bus, and an electrical storage device is electrically connected to the electrical bus. The at least one piston is movably mounted such that its motion electromagnetically induces current in the electrical circuit. An electronic controller is electronically connected to the electronic power converter to control motion of the at least one piston to perform, in the thermal cycle, at least one of: (i) expanding the working gas beyond the volume at which compression of the working gas is begun within the thermal cycle or (ii) exhausting the working gas to a remaining volume less than the smallest volume of compressed gas within the thermal cycle. The electronic controller further controls flow of electrical energy to and from the electrical bus to effect a net positive average power transfer from the working gas to the electrical bus over the course of the thermal cycle.

摘要： The power output of a free piston Stirling engine mounted in a free casing configuration is controlled by having a spring drivingly linking the displacer to the casing and controllably varying the amplitude of reciprocation of the casing. A variable casing reciprocation restraint is linked to the casing for applying a variable restraining force to the casing. The restraining force is increased for decreasing the displacer amplitude of reciprocation and thereby decreasing the power output from the Stirling engine and the restraining force is decreased for increasing the displacer amplitude of reciprocation and thereby increasing the power output from the Stirling engine.

摘要： A standing wave thermoacoustic piezoelectric apparatus capable of generating electrical energy from heat energy is provided. The standing wave thermoacoustic piezoelectric apparatus includes a housing, a porous stack and a piezoelectric bimorph. The housing comprises a compressible fluid and has a first portion and a second portion. The second portion receives the heat energy from a heat source for creating a temperature gradient between the first portion and the second portion. A cold heat exchanger within the first portion is positioned at one end of the porous stack. The compressible fluid traverses between the first portion and the second portion through the porous stack to generate standing acoustic waves for generating acoustic energy. The piezoelectric bimorph positioned at an end of the first portion opposite to an end of the first portion having the cold heat exchanger, oscillates based on the acoustic energy for generating the electrical energy.

摘要： A bearing support system for a piston and its connecting rod in which the bearing system supports the combined piston and connecting rod by only two bearings, a gas bearing at the power piston (or displacer) and a radially acting spring bearing at its connecting rod. The spacing between them meets prescribed relationships and preferably exceeds a calculated value based upon chosen engineering parameters. A non-compliant connecting rod is fixed to an end of a piston which has a clearance seal length in the range of 0.3 times the diameter of the piston and 1.5 times the diameter of the piston. The distance from the gas bearing to the effective point of connection of the radially acting spring bearing to the connecting rod is greater than the seal length of the piston. The allowable off-center distance A for the radial displacement of the fixed connection of the radially acting spring bearing to the connecting rod is considerably greater than the diametrical clearance gap g which illustrates the reduction in the required precision for adjusting the position of the radially acting spring bearing. The piston and connecting rod unit is not supported by additional bearings that introduce additional alignment problems.
