AC GENERATOR WITH EXTERNAL COMBUSTION ENGINE Russian patent published in 2015 - IPC H02K7/18 H02K35/06 F02G1/05 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine-generator systems. Proposed generator comprises cylinder, working piston, refrigerator and heater as well as circular winding on said cylinder. Said cylinder is divided by displacement piston to cold and hot chamber. Said working piston slides in cold chamber. Refrigerator, generator and heater are arranged in series to communicate said cold and hot chambers. Working piston is rigidly coupled piston made of magnetic material. Winding cores feature double-tee cross-section. Ring magnets facing each other by unlike poles are arranged on both sides of said cores. Piston rod has circular grooves filled with nonmagnetic material. Piston position transducer is fitted on cylinder nearby displacement piston connected in series via microprocessor with control valve on pipeline nearby heater and cold chamber.

EFFECT: higher efficiency and reliability.
