HEAT ENGINE WITH EXTERNAL HEAT SUPPLY

摘要

FIELD: heating.SUBSTANCE: heat engine with external heat supply includes four bellows at the hot side of engine, connected to heaters, and four bellows at the cold side of engine, connected to coolers. Internal space of bellows forms cavities of alternate volume for compression and expansion of gaseous work medium. Heater is connected to cooler by a pipeline through heat exchange duct. Lower end of bellow is propped by its pusher on an eccentric cam. Eccentric cams at the hot and cold side are phase-shifted against each other by 180°. Second eccentric cams are phase-shifted against the first eccentric cams by 90°. Third eccentric cams are phase-shifted against the second eccentric cams by 90°. Fourth eccentric cams are phase-shifted against the third eccentric cams by 90°. Four eccentric cams at the hot side of engine are mounted on a first common shaft with a first linking gear. Four eccentric cams at the cold side of engine are mounted on a second common shaft with a second linking gear. First and second linking gears are connected by chain belt drive.EFFECT: increased operation life at the same power of engine.2 cl, 2 dwg
