Abstract

La présente invention se rapporte à un système de sécurité d'alimentation en liquide d'un organe utilisateur tel un servofrein. Selon l'invention, la pompe 1 alimente un organe utilisateur 5, à travers une soupape de retenue 4. Ledit organe 5 peut également être alimenté par un accumulateur 3 à travers la soupape 7 si la pompe tombe en panne. Ledit accumulateur est chargé par la pompe lorsque la pression du liquide fournie par celle-ci est supérieure à celle existant dans l'accumulateur. L'invention est du domaine de l'automobile.
