Title (EN) CIRCULATORY ASSISTANCE SYSTEM
(FR) SYSTÈME D'ASSISTANCE CIRCULATOIRE
Abstract:
(EN) The invention relates to a circulatory assistance system (1) comprising: a rotor (10) in the shape of a Reuleaux triangle; and a camshaft (20) received in a housing of the rotor (10) and designed to rotate the rotor (10) about an axis of rotation (X). The inner walls (15) of the housing of the rotor (10) are in contact at all points with the outer surface of the cam (24) such that the assembly formed by the cam (24) and the rotor (10) does not have a clearance volume.
(FR) L'invention concerne un système d'assistance circulatoire (1) comprenant : - un rotor (10) ayant la forme d'un triangle de Reuleaux, - un arbre à came (20) logé dans un logement du rotor (10) et configuré pour entraîner en rotation le rotor (10) autour d'un axe de rotation (X). les parois internes (15) du logement du rotor (10) étant en contact en tout point avec la surface externe de la came (24) de sorte que l'ensemble formé par la came (24) et le rotor (10) est dépourvu d'espace mort.
