Title (EN) DEVICE FOR ADJUSTING THE BOOST PRESSURE OF COMBUSTION ENGINES
(FR) DISPOSITIF DE REGLAGE DE LA PRESSION D"ADMISSION POUR MOTEURS A COMBUSTION
Abstract: front page image
(EN)A combustion engine provided with an exhaust gas turbocharger (1) has a control valve (9) disposed within a bypass conduit (8) by passing the exhaust gas turbin. The actuating member (11) of the valve is controlled by a control pressure depending on the surrounding temperature and pressure, on one side, directly, towards the opening at the boost pressure, on the other side by a closure spring (16) towards the closure. A device (20; 120; 220) sets at a high value at least constant the pressure of the control air derived from the boost air in case of a drop off of the surrounding pressure and/or of a rise of the surrounding temperature.
(FR)Un moteur a combustion comportant un turbocompresseur (1) a gaz d"echappement presente une soupape de commande (9) disposee dans une conduite (8) de derivation contournant la turbine (3) a gaz d"echappement. L"organe d"actionnement (11) de la soupape est commande par une pression de commande dependante de la temperature et de la pression ambiantes, d"une part, directement, en direction de l"ouverture a la pression d"admission, d"autre part par un ressort de fermeture (16) en direction de la fermeture. Un dispositif (20; 120; 220) etablit a une valeur elevee au moins constante la pression de l"air de commande derive de l"air d"admission lors d"une baisse de la pression ambiante et/ou d"une elevation de la temperature ambiante.
