Throttle device for IC engine - has housing containing throttle channel and throttle valve shaft extending across throttle channel and rotatably located in housing

摘要

The throttle valve shaft has a slot which is located inside the throttle channel and in the slot is fixed the throttle valve. The throttle valve is formed from two part throttle valves (16,17) and each part throttle valve has a fixture tab (13), which extends into the slot (4). The length of the slot in the throttle valve shaft (3) is smaller than the dia. of the throttle channel. Each fixture tab (13) has a recess (14) open towards the other, through which a connecting component engages. Two or more connecting components are used for fixing each fixture tab to the throttle valve shaft (3). The throttle valve shaft (3) on both sides of the slot (4) has axial grooves (15) displaced through 180 deg. to accommodate the part throttle valves (16,17). USE/ADVANTAGE - To reduce the amount of leaked air through the throttle of an IC engine.
