摘要

Hereunder an electromagnetically-controlled valve suitable for controlling an additional air flow in a feed equipment for an internal combustion engine, is described: it includes an air inlet from a room exposed to the atmospheric pressure and air outlet orifices to a room with lower pressure, with a first by-pass channel for the above mentioned inlet and a second one for the air coming out of the orifices; the invention is characterized by the fact that it includes an obturator to vary the passage section of the above mentioned orifices under the action of an electromagnet and a contrast spring.
