Title
(EN) SLIDING VANE PUMP
(FR) POMPE À PALETTES COULISSANTES
Abstract
(EN)
The present disclosure provides a fluid pump having a pump motor, a pump drive shaft and a vane pump assembly. The vane pump assembly includes pump housing with a fluid inlet port in a distal portion of the housing and a fluid outlet port in a proximate portion. A first bearing member, having a plurality of inlet orifices in flow communication with the fluid inlet port, is disposed within the housing distal portion. A cam ring is adjacent the first bearing member. A rotor, which is on mounted the pump drive shaft, is disposed within an opening in the cam ring. This rotor includes a plurality of radial slots and vanes slidably received within the slots. A second bearing member, having a plurality of outlet orifices in flow communication with the fluid outlet port, is disposed within the housing proximate portion adjacent the cam ring. An end plate is also mounted within the distal portion of the pump housing. Rotation of the rotor by the drive shaft causes fluids from the fluid inlet port to be drawn through the plurality of inlet orifices at an initial fluid pressure. The fluid are then directed along a plurality of fluid flow paths disposed between an inner surface of the cam ring and an outer surface of the rotor, and then ejected through the plurality of outlet orifices to the fluid outlet port at a second fluid pressure which is greater than the initial fluid pressure.

La présente invention a pour objet une pompe à fluide comprenant un moteur de pompe, un arbre d'entraînement de pompe et un ensemble pompe à palettes. L'ensemble pompe à palettes comprend un logement de pompe doté d'un orifice d'admission de fluide dans une partie distale du logement et d'un orifice de sortie du fluide dans une partie proximale. Un premier élément de support, comprenant une pluralité d'orifices d'admission en communication fluidique avec l'orifice d'admission du fluide est disposé à l'intérieur de la partie distale du logement. Un anneau à came est adjacent au premier élément de support. Un rotor, qui est monté sur l'arbre d'entraînement de la pompe, est disposé à l'intérieur d'une ouverture de l'anneau à came. Ce rotor comprend une pluralité de fentes radiales et de palettes logées de coulissante dans les fentes. Un second élément de support, comprenant une pluralité d'orifices de sortie en communication fluidique avec l'orifice de sortie du fluide, est disposé à l'intérieur de la partie proximale du logement adjacente à l'anneau à came. Une plaque d'extrémité est également montée à l'intérieur de la partie distale du logement de la pompe. La rotation du rotor par l'arbre d'entraînement permet d'attirer les fluides de l'orifice d'admission du fluide vers la pluralité d'orifices d'admission à une pression de fluide initiale. Les fluides sont alors dirigés le long d'une pluralité de voies d'écoulement de fluide disposées entre une surface interne de l'anneau à came et une surface externe du rotor, puis éjectés à travers la pluralité d'orifices de sortie vers l'orifice de sortie de fluide à une seconde pression de fluide qui est supérieure à la pression de fluide initiale.
