摘要： A high efficiency energy conversion system disclosed herein incorporates a piston assembly including a sealed cylinder for storing a working fluid and an energy conversion element attached to the piston assembly. A kinematic mechanism such as a cam lobe or a scotch yoke may be used as the energy conversion element. In one implementation, the kinematic mechanism may be configured to provide rapid piston expansion in a manner so as not to allow the expanding working fluid inside the piston to achieve thermodynamic equilibrium. In an alternate implementation, the kinematic mechanism is further adapted to generate a compression stroke in a manner to provide the working fluid inside the piston to achieve thermodynamic equilibrium conditions throughout the compression stroke.

摘要： A Stirling engine can take advantage of adiabatic compression (which heats working gas leaving the cold cylinder) and adiabatic expansion (which cools working gas leaving the hot cylinder) to increase efficiency. In some implementations, partially-heated gas leaving the cold cylinder and partially-cooled gas leaving the hot cylinder can be routed directly to a regenerator using bypass paths that are opened using one-way valves. The resultant relatively reduced temperature difference across the regenerator, e.g., as compared to a typical Stirling engine, can reduce thermal loss and improve efficiency. In some implementations, the compression ratios of the Stirling engine can be adjusted such that the temperature of the adiabatic heated gas is the same or higher than the temperature of the adiabatic cooled temperatures, thus eliminating the need for a regenerator.

摘要： A hot zone heat transfer structure of a Stirling engine is provided. One end of a cylinder includes a heated head, with its end wall connected with a hot air pipe. The cylinder accommodates a piston. The piston has an end surface corresponding to the end wall, between which a hot zone is defined. The end wall is fitted with a protruding heat conductor towards the piston, and the end surface is fitted with a concave heat-conducting portion, enabling normal overlapping of the ends of both the heat conductor and the heat-conducting portion. The overlapping may vary with the changing locations of the piston. A flanged section is set externally onto said heat conductor towards the exterior of the end wall. The heat from the head can be transferred to the central area of the hot zone via the help of the heat conductor and heat-conducting portion.

摘要： A linear free piston Stirling machine having a displacer piston mounted on first and second planar springs. The first spring has a stiffness which increases with increasing spring displacement. The second has a stiffness which is less variable with spring displacement to provide a combined stiffness which rapidly increases once the displacer piston displacement exceeds a fixed limit. Each of the springs has a plurality of spiral spring portions and a stress relieving hole beyond the outer edge of the spiral spring portions.

摘要： The concentricity and coaxiality of a central bore through a piston for a free piston Stirling machine is improved with a piston that has a sleeve with a core constructed from at least two, separate, axially-engaging core components sealed within the sleeve. During fabrication, a central bore is machined through each of the core components. The piston is assembled by heating the sleeve and cooling the core components, inserting the core components into the sleeve and then allowing the sleeve to cool and the core components to warm. This drives the core components into sealed engagement with each other and with the sleeve and aligns the central bore coaxially with the outer cylindrical surface of the sleeve.

摘要： With spacers (30, 31) held between the central portion and the circumference of two plate springs (61, 61), a fixed shaft (67) erected on a fixed block (70) is inserted in a through hole (64) in the periphery of the plate spring (61) and also in the spacer (31), and nuts (68, 68) are applied for tightening from above and below (step #1). Thereby, a displacer supporting spring (6) is fixed to the fixed block (70). And the threaded portion (2b) of a rod (2a) is inserted in a through hole (63) in the center of the plate spring (61) and also in the spacer (30) from the upper surface side of the upper plate spring (61), and a nut (32) is attached to the threaded portion (2b) projecting from the lower surface of the lower plate spring (61) so as to fix the displacer (2) to the upper surface side of the upper plate spring (61) (step #2). In this state, small vibration is applied to the displacer supporting spring (6) (step #3). And the resonance frequency is detected (step #4) and on the basis of this result, the spring constant of the displacer support spring (6) (the combined spring constant of the two plate springs (61, 61)) is calculated, and then an additional weight ΔWd reaching the target resonance frequency is calculated (step #5).
