BAROMETRIC ENGINE Russian patent published in 1998 - IPC

FIELD: power engineering and water transport. SUBSTANCE: engine has crank gear, timing gear, lubricating system, control unit, and wind vane. Novelty is that each pair of cranks is spaced 180 deg. apart and each next crank is displaced through 90 deg. relative to preceding one; cranks are coupled through connecting rods and stems to pistons placed inside double-action cylinders whose inner spaces are connected via timing gear to high- and low-pressure pipelines which are connected via flexible hoses to air intake and to internal space of wind vane through tube made in the form of contracting-expanding nozzle , respectively; in addition, crankshaft is coupled through power amplifier with engine shaft carrying control unit with crankshaft speed governor. EFFECT: reduced noise and fire hazard, facilitated starting and stopping, improved environmental friendliness, reduced heat loss, provision for dispensing with fossil fuel. 5 cl, 24 dwg
