Abstract

Une pompe tandem comporte une pompe à piston (1) et une pompe à cellules semi-rotative (2) qui possèdent un arbre d'entraînement (4) commun. La pompe à cellules semi-rotative (2) est fixée derrière la pompe à piston (1) sur l'extrémité de l'arbre d'entraînement. La pompe a une structure en éléments mobiles, la pompe à piston (1) étant disposée dans un boîtier de piston (3) ouvert sur l'avant et la pompe à cellules semi-rotative (2) dans un boîtier de pompe à cellules semi-rotative (5) ouvert sur l'avant, un couvercle intermédiaire (6) étant situé entre les deux avants ouverts adjacents l'un à l'autre. Le couvercle intermédiaire (6) relie les deux boîtiers (3, 5) entre eux et présente un creux central dans lequel est disposé l'arbre d'entraînement (4). Dans la paroi avant (13) du couvercle intermédiaire (6) qui est adjointe à la pompe à cellules semi-rotative (2) est moulé le miroir de commande (cavités réniformes d'aspiration (14), cavités réniformes de pression (15)) pour la pompe à cellules semi-rotative (2).
