(FR) UNITÉ DE POMPAGE POUR FOURNIR À UN UTILISATEUR DE L'HUILE SOUS PRESSION
Abstract: front page image
(EN)A pumping assembly for feeding oil under pressure to a user is defined by a gear pump (2), which is actuated by an electric motor (3), and has a pair of gears (4), which are coupled to each other within a pump body (9), and are each provided with a respective plurality of teeth (8) facing radially to a respective lateral surface (12) of the pump body (9) and axially to two recesses (23) formed on two side elements (15) of the pump body (9) itself; the radial distance (Dr) of the teeth (8) from the respective lateral surface (12) increasing in the direction of rotation of the gears (4) around their own rotation axes (6).
(FR)L'invention concerne un ensemble de pompage pour fournir un utilisateur de l'huile sous pression comprenant une pompe à engrenages (2) qui est actionnée par un moteur électrique (3) et comporte une paire de roues dentées (4) qui sont accouplées entre elles à l'intérieur d'un corps de pompe (9) et sont chacune dotées d'une pluralité respective de dents (8) faisant face radialement à une surface latérale respective (12) du corps de pompe (9) et axialement à deux creux (23) formés sur deux éléments latéraux (15) du corps de pompe (9) lui-même; la distance radiale (Dr) entre les dents (8) et la surface latérale respective (12) augmente dans la direction de rotation des roues dentées (4) autour de leur propre axe de rotation (6).
