Abstract

Le corps (3) de cet appareil comporte un dispositif de régulation de débit (17) comportant un orifice calibré (18) situé sur un circuit d'alimentation en fluide haute pression, un alésage ménagé dans le corps (3) et dans lequel est monté un tiroir (19) dont une première face est située dans une première chambre reliée au circuit d'alimentation en fluide haute pression en amont de l'orifice calibré (18) et dont la seconde face est située dans une seconde chambre reliée au circuit d'alimentation en fluide haute pression en aval de l'orifice calibré (18), l'alésage recevant le tiroir (19) comportant une gorge annulaire reliée à un circuit de retour basse pression (10). Le tiroir (19) est agencé pour relier la gorge annulaire à la première chambre lorsque la différence des pressions de part et d'autre de l'orifice calibré (18) augmente au delà d'une valeur prédéterminée, de manière à dévier une partie du débit de fluide fourni par le circuit d'alimentation en fluide haute pression vers le circuit de retour (10).
