Abstract
PURPOSE: To improve exhaust faculty and fuel consumption by operating a shutter valve even in low revolution deceleration range in the vicinity of idling operation of an engine and setting the shutter valve in inoperative state in no-load operation.
CONSTITUTION: When the composite intake negative pressure which is introduced into a negative pressure chamber 16C exceeds the prescribed negative pressure, the valve body 16m of a controller 16 opens due to the dispalcement of a diaphragm 16a, and the composite intake negative pressure is introduced into the negative pressure chamber 12d of an operation diaphragm apparatus 12 through an intake negative pressure introducing chamber 16f and a communication pipe 15. The diaphragm 12a is displaced against the force of a coil spring 12c, and an operation rod 13 is pulled in, and a closing lever 11 is turned to the opening direction against the spring force of a return spring 14, and a shutter valve 9 is perfectly opened. On the contrary, when the turning of a throttle valve 8 is large, the shutter valve is perfectly opened by a relatively high intake negative pressure.
