Abstract

The bypass channels (4) are each switched individually by an in-channel valve (5) and with channel and valve bearing inside an adaptor (8,13). The valves are mounted in axi-parallel and are adjustably interconnected by gearing (14). Guide faces (16) of the valves in the open air flow line (15) lie between bypass and intake channel (3) so the cylindrical casing surfaces of the guides correspond to the walls of the bypass channels. The bypass channels have shouldered (19,20) inlet and outlet sections and the valves in the adaptors are injection castings or else are sprayed on round the adaptors. The valve bearing boss projects from the adaptor and is injection-cast to the lever. These are interconnected in turn by rods. One lever in addition is joined to an outwards projecting actuator.
