Control valve assembly

The switch flap assembly, to take a number of switch flaps (20) for an air intake channel system (10) at an internal combustion motor, has a switch shaft (24) bonded to the flaps. As the shaft rotates, the flaps are moved into a setting (20'). The flaps and the shaft are carried by a common frame (22), to be assembled together for installation as a complete unit. The frame walls (34,36,38) at least partially form a short circuit channel (28) for the air intake channel system.
