ABSTRACT:
An air intake installation of an internal combustion engine consisting of an I-shaped distributor member which is formed of two resonant chamber and of a connecting pipe connected to the air filter. Two bypass pipes are additionally located between the two resonant chamber in parallel with the connecting pipe, of which one is also connected with the air filter by way of an intake connection. The other bypass pipe and the connecting pipe are adapted to be closed off with respect to the resonant chamber by way of throttle valves located near the ends of the connecting pipe and of the other bypass pipe. By corresponding actuation and adjustment of the throttle valves, the connecting cross sections between the resonant chambers which effect the resonance can be adjusted in three stages and the resonance point can be displaced correspondingly into different rotational speed ranges.
