摘要

The venturi device (V) can be bypassed by a main air sequence (21), the through-flow of which is controllable by a control unit (22). The venturi device is multichanneled and has at least two parallel connected nozzle - diffuser units (20), arranged in a common housing (25). The main air sequence and control unit are integrated in the housing of the venturi device. The housing of the venturi device is cylindrical and has two separated part chambers (27,28) in a longitudinal direction, whereby in the first part chamber the nozzle - diffuser units are arranged and the second part chamber contains the control unit.
