Title (EN) DEVICE FOR BALANCING AND CONTROLLING THE PRESSURE IN AT LEAST TWO CHAMBERS,IN PARTICULAR IN THE TYRES OF A VEHICLE
(FR) DISPOSITIF POUR EQUILIBRER ET CONTROLER LA PRESSION DANS AU MOINS DEUX CHAMBRES, EN PARTICULIER DANS LES PNEUMATIQUES D"UN VEHICULE
Abstract:
(EN) The device is used for balancing and controlling the pressure in at least two pressurized chambers, in particular in the tyres of a vehicle. A pressurized chamber (1), provided with a pipe which can be closed (5), is obturated by means of an annular valve (2). A loaded spring (3) presses the valve (2) against its seat (4) where the connection channel (7, 8) of a pressurized chamber opens to; the free surface of the valve (2) directed towards the pressurized chamber (1) is bigger than the area of the opening of the connection channel (7, 8). To keep the valve (2) closed, if the pressure increases beyond the rated pressure in one chamber, the connection channels (7, 8) of all the chambers open on to the valve seat (4) and can be closed by means of the valve (2). Further, the total area of the openings (9, 10) of the connection channels (7, 8) is bigger than the surface of the valve (2) directed towards the pressurized chamber (1).
(FR) Le dispositif sert a equilibrer et a controler la pression dans au moins deux chambres pressurisees, en particulier dans les pneumatiques d"un vehicule. Une chambre pressurisee (1), munie d"une canalisation pouvant etre fermee (5), est obturee au moyen d"une soupape annulaire (2). Un ressort sous tension (3) presse la soupape (2) contre son siege (4), dans lequel le canal de raccordement (7, 8) d"une chambre pressurisee debouche, la surface libre de la soupape (2) tournee vers la chambre pressurisee (1) est plus grande que la surface de l"embouchure du canal de raccordement (7, 8). Pour maintenir fermee la soupape (2), si la pression augmente au-dessus de la pression nominale dans une chambre, les canaux de raccordement (7, 8) de toutes les chambres aboutissent dans le siege de soupape (4) et peuvent etre fermes au moyen de la soupape (2). En outre, la somme des surfaces de toutes les embouchures (9, 10) des canaux de liaison (7, 8) est plus petite que la surface de la soupape (2) tournee vers la chambre pressurisee (1).
