Abstract

La valvola (10) è atta ad essere inserita tra un contenitore di vapori di carburante (7) collegato con il serbatoio del carburante (1) di un autoveicolo e tra un dispositivo (2) per il controllo del flusso d'aria di alimentazione del motore; la valvola comprende un organo otturatore mobile (14) azionato elettromagneticamente ed atto a controllare il passaggio dei vapori tra un foro di ingresso (15) ed un foro di uscita (16) ed è caratterizzata dal fatto di essere provvista di superfici di accoppiamento (17a, 17b, 17c) atte ad essere accoppiate con corrispondenti superfici di una sede (18) che è ricavata in un corpo (13) del suddetto dispositivo formatore di una miscela e che è in comunicazione con un condotto (4) del corpo stesso che è attraversato dalla miscela suddetta, il foro di uscita (16) della valvola sboccando in una zona all'interno di dette superfici di accoppiamento (17a, 17b, 17c) in modo da essere in comunicazione con detta sede (18) del corpo.The valve (10) is adapted to be inserted between a fuel vapor container (7) connected with the fuel tank (1) of a motor vehicle and between a device (2) for controlling the supply air flow of the engine; the valve comprises a movable shutter member (14) electromagnetically operated and adapted to control the passage of the vapors between an inlet hole (15) and an outlet hole (16) and is characterized in that it is provided with coupling surfaces (17a , 17b, 17c) adapted to be coupled with corresponding surfaces of a seat (18) which is obtained in a body (13) of the aforesaid mixture forming device and which is in communication with a conduit (4) of the body itself which is the outlet hole (16) of the valve crossed by the above mixture, opening into an area inside said coupling surfaces (17a, 17b, 17c) so as to be in communication with said seat (18) of the body.
