5results about "Regenerators" patented technology

A STIRLING-FRANCHOT type heat engine comprising a reciprocating cylindrical piston (101) and another reciprocating cylindrical piston (107). A fixed quantity of working gas oscillates in a first circuit composed successively of the portion of the chamber (102) located above the piston (101), an additional regenerator (120), a heater (103), a conventional regenerator (104), a cooler (105), an additional regenerator (160), and finally the portion of the chamber (106) located above the piston (107). A second equivalent fixed quantity of working gas oscillates in a second parallel circuit.In four parallelepiped-shaped elements, plugs (1103), (1203), (1205) and (1105) are easily removable, and additional regenerators can be removed or added in whole or in part to achieve the configuration that optimizes the efficiency or power of each application (engine, heat pump, or refrigerator). Figure for the abbreviation: FIG10.

A system for energy conversion including a closed cycle engine having a piston body defining a hot side and a cold side and having a piston assembly movable within the piston bod. An electric machine is operatively coupled with the piston assembly and is operable to generate electrical power when the piston assembly is moved within the piston chamber. A control system includes one or more sensors operable to detect a piston movement characteristic of the piston assembly movable within the piston body. A controller is communicatively coupled with the one or more sensors and a controllable device. The controller is configured to determine a control command based at least in part on data received from the one or more sensors. The control command is selected based at least in part to cause the electric machine operatively coupled with the piston assembly to generate a preselected electrical power output.

A new thermal engine design and novel hot air inlet provide a high-efficiency hot-gas free-piston Stirling engine design.

Wire mesh (1) for a regenerator device (100), comprising at least one layer (2) of fabric made of warp wires (3) and weft wires (4), wherein the warp wires (3) and the weft wires (4) are interwoven and span at least one fabric surface (6), wherein the warp wires (3) extend along a first extension (7) of the fabric surface (6) and wherein the weft wires (4) extend along a second extension (8) of the fabric surface (6), characterized in that the fabric surface (6) has at least one interruption (9) which interrupts at least one weft wire (4) and / or at least one warp wire (3) along the first extension (7) and / or the second extension (8) of the fabric surface (6) at least once.

A system for energy conversion, the system including a closed cycle engine defining a hot side and a cold side, a heater loop positioned at least in part in a heat exchange relationship with the hot side of the closed cycle engine for imparting thermal energy thereto, and a hot side heat exchanger positioned along an intake line of the heater loop, wherein the heat loop has a heat recovery loop operable to recover heat from the hot side and return the recovered heat to the hot side, and wherein the heat recovery loop has a recirculation loop in fluid communication with the intake line for recirculating heating working fluid to the hot side heat exchanger.
