FOUR-STROKE ROTARY-VANE ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: crankshaft is mounted in housing of four-stroke rotary vane- engine. Working necks of crankshaft are connected with vanes by means of sliders and guides in rotors. Support necks are also installed in sliders reciprocating in crossing guides of four crossheads forming at least two support units. These units provide eccentric mounting of crankshaft relative to axis of rotors and possibility of rotation of crankshaft proper simultaneously with planetary rotation relative to support units. Output necks provide transmission of torque to power takeoff shaft by means of guide mechanisms furnished with counterweights. So, crankshaft provides coupling of vanes which makes it possible to redistribute loads, caused by action of gas and inertia forces, over larger contact surfaces covering working necks of bearings. EFFECT: enlarged operating capabilities. 2 cl, 6 dwg
