<p>PURPOSE:To make available the effective control of engine output, by providing the moving vane at the inlet side of a turbosupercharger and by operating the moving vane correspondingly to engine r.p.m. and engine load. CONSTITUTION:When an engine is running at its r.p.m. C, first and second electromagnetic valves 6, 7 are not energized and so the air is not supplied from an air tank 9 to an actuator cylinder 8. Pistons 13, 14 are displaced in the left direction, a moving vane 17 is rotated in a counterclockwise direction, and a turbine nozzle has its area F3. When the engine r.p.m. is B, a valve 6 operates solely and the air is supplied to a chamber 9, thereby displacing the first piston 13 in the right direction and rotating the moving vane 16 in a clockwise direction. When the engine r.m.p. is A, valves 6, 7 are operated to supply air into chambers 9, 10, causing the moving ring 16 to rotate to its maximum clockwise direction. As a result, an area of turbine nozzle is reduced to its minimum F1.</p> |
