Abstract

L'invention concerne un régulateur de pression destiné à commander la pression de sortie d'une pompe à fluide. Le régulateur comprend un premier élément 18 comportant au moins un orifice 19 débouchant sur une surface de cet élément, un second élément 23 rappelé en contact avec ladite surface de façon à obturer l'orifice, un organe élastique 24 rappelant l'élement 23 en contact avec ladite surface et un organe sensible à la vitesse 27 agissant dans le même sens que le ressort. La pression de sortie de la pompe est commandée en fonction de la force exercée par le ressort et par l'organe sensible à la vitesse. Application à la commande de la pression de combustible fournie à une pompe d'injection pour moteur à combustion interne.
