SELF-CONTAINED POWER UNIT WITH FLUIDYNE ENGINES Russian patent published in 1999 - IPC

FIELD: power engineering, equipment operating in agreement with Stirling cycle. SUBSTANCE: invention is intended to increase efficiency of unit as whole thanks to exclusion of energy losses for friction and to simplify design of unit owing to conversion of oscillatory motion of columns of liquid in outlet tubes of engines to useful electric energy. Operation of engines 1 and 2 causes forced oscillations of columns of liquid in outlet tubes 8 and 9. Counterphase reciprocating translations of columns of liquids in tubes 8 and 9 cause reciprocating translations of magnet 7 along axis of coil 13 which leads to generation of electric current. Magnet 7 is connected to outlet tubes 8 and 9 with the aid of inserts 10 and 11 made from corrugate restoring material. Synchronism of movement of levels of columns of liquid in tubes 8 and 9 ( their counterphase ) is determined by phase shift between Fluidyne engines 1 and 2 that is regulated by means of throttle valve 14. EFFECT: increased efficiency and simplified design of power unit. 1 dwg
