Abstract
On propose une pompe tourbillonnaire qui sert à alimenter un moteur à combustion interne d'un véhicule à moteur avec un carburant contenu dans un réservoir. La pompe tourbillonnaire (12) comprend une roue mobile cylindrique circulaire (14) tournant dans une chambre de pompe (19), qui présente, sur une de ses deux faces frontales (44, 48) au moins, une couronne d'ailettes (38) disposées à la périphérie de la roue mobile et mutuellement espacées, et la base de l'interstice (42) en forme d'encoche forme, lorsqu'on l'observe selon une coupe longitudinale de la pompe, un segment de cercle (46, 50) entre deux ailettes voisines (38), segment de cercle dont le centre (62, 64) est au moins pratiquement identique au centre d'un autre segment de cercle (58, 60) formé par la base d'un canal d'alimentation (54, 56) approximativement circulaire opposé à la couronne d'ailettes et disposé dans une paroi (20) de la chambre (19) de la pompe. Une augmentation sensible du rendement de la pompe tourbillonnaire est obtenue lorsque les centres (62, 64) des deux segments de cercle (46, 58, 50, 60) sont inclus dans la périphérie de la roue mobile (14).A vortex pump is provided which serves to supply an internal combustion engine of a motor vehicle with fuel contained in a tank. The vortex pump (12) comprises a circular cylindrical mobile impeller (14) rotating in a pump chamber (19), which has, on one of its two end faces (44, 48) at least, a ring of fins (38 ) arranged at the periphery of the movable impeller and mutually spaced, and the base of the notch-shaped gap (42) forms, when observed in a longitudinal section of the pump, a segment of a circle (46 , 50) between two neighboring fins (38), segment of circle whose center (62, 64) is at least practically identical to the center of another segment of circle (58, 60) formed by the base of a channel d The approximately circular feed (54, 56) opposite the fin crown and disposed in a wall (20) of the pump chamber (19). A substantial increase in the efficiency of the vortex pump is obtained when the centers (62, 64) of the two circle segments (46, 58, 50, 60) are included in the periphery of the impeller (14).
