Claims

[Scope of utility model registration request]

An air intake system comprising a bypass air passage that communicates between an upstream side and a downstream side of a throttle valve position in an intake passage, an air valve that changes the amount of air passing through the bypass air passage, and an actuator that operates the air valve. In the quantity control device, an auxiliary bypass air passage is provided that connects the bypass air passage upstream from a passage cross-sectional variable position by the air valve in the bypass air passage and the bypass air passage downstream from that position or the intake passage downstream from the throttle valve position. 1. An air amount control device comprising: an auxiliary valve for changing the passage cross section of the auxiliary bypass air passage;
