Abstract

La présente invention concerne une pompe à haute pression. Elle comporte un boîtier 1, une came annulaire 7, un rotor 6 entraîné par un axe de rotation 5, une plaque de commande 4 solidaire du boîtier 1 et une plaque de commande libre 10. Cette pompe est caractérisée en ce que les plaques de commande 4 et 10 sont réalisées en un alliage à haute teneur de silicium par un procédé d'injection sous vide. Ces pompes sont particulièrement utilisées pour engendrer l'huile sous pression dans les directions assistées.The present invention relates to a high pressure pump. It comprises a housing 1, an annular cam 7, a rotor 6 driven by an axis of rotation 5, a control plate 4 integral with the housing 1 and a free control plate 10. This pump is characterized in that the control plates 4 and 10 are made of an alloy with a high silicon content by a vacuum injection process. These pumps are particularly used to generate pressurized oil in power steering.
