The hose pump comprises an eccentric drive with numerous eccentric discs (21) fastened to a shaft (20). Each eccentric disc (21) drives a crank drive (24) with a connecting rod (25). At the end of the connecting rod (25), a pump finger (11) is borne which compresses a pump hose (10). A sealing diaphragm (27) preventing liquid from intruding into the interior of the housing (16) is disposed between the eccentric drive and the pump hose (10). The sealing diaphragm (27) comprises lateral folds (31) so that it does not exert any substantial forces upon the crank drive (24). The hose pump has a iow power consumption and permits a small structure.
Pompe à tuyau péristaltique doté d'un mécanisme d'entraînement excentrique muni de plusieurs disques excentriques (21) fixés à un arbre (20). Chaque disque excentrique (21) entraîne un vilebrequin (24) muni d'une biellette d'accouplement (25) dont l'extrémité est dotée d'un poussoir (11) qui comprime un tuyau (10). Un diaphragme (27), placé entre le mécanisme d'entraînement excentrique et le tuyau de la pompe (10), assure l'étanchéité et empêche le liquide de pénétrer dans le carter (16). Des plis latéraux (31) sont aménagés dans le diaphragme (27) afin que celui-ci n'exerce pas une pression trop grande sur le vilebrequin (24). Cette pompe consomme peu de courant et son format est compact.
