Title (EN) ROTARY VANE PUMP WITH VARIABLE CONVEYING QUANTITY
(FR) POMPE À PALETTES ROTATIVE À VOLUME DE TRANSPORT VARIABLE
Abstract:
(EN) A rotary vane pump with variable conveying quantity, comprising a housing arrangement (4) which encloses a housing chamber (6) having arranged therein a displaceable eccentric ring (8) accommodating an inner rotor member (12) that is rota table relative to the eccentric ring (8) and that is supported in the housing arrangement (4) to be driven by drive means via a rotary axis (14), wherein the inner rotor member (12) comprises slits (16) having vane elements (18) displaceably supported in them, wherein a cover element (40) is provided for closure of the housing chamber (6) and wherein the housing arrangement (4) has an inlet opening (28) and an outlet opening (30) provided in it, wherein, in the housing chamber (6), between the eccentric ring (8) and the inner rotor member (12), an outer rotor member (22) is provided which on its inner side (24) is engaged by the vane elements (18) so as to enclose pump chambers (26), wherein the outer rotor member (22) is coupled via a coupling arrangement (32) to the inner rotor member (12) in a torsionally rigid manner while, however, being displaceable in radial direction.
(FR) L'invention concerne une pompe à palettes rotative à volume de transport variable, comprenant un arrangement de carter (4) qui renferme une chambre de carter (6) dans laquelle est disposé un anneau excentrique déplaçable (8) accueillant un élément de rotor interne (12) qui peut tourner par rapport à l'anneau excentrique (8) et qui est supporté dans l'arrangement de carter (4) en vue d'être entraîné par des moyens d'entraînement par le biais d'un axe de rotation (14). L'élément de rotor interne (12) comprend des fentes (16) dans lesquelles des éléments de palette (18) sont supportés de manière déplaçable. Un élément formant couvercle (40) est présent pour la fermeture de la chambre de carter (6) et l'arrangement de carter (4) comporte une ouverture d'entrée (28) et une ouverture de sortie (30) disposées dans celui-ci. Un élément de rotor externe (22) se trouve dans la chambre de carter (6), entre la bague excentrique (8) et l'élément de rotor interne (12), lequel est mis en prise par les éléments de palette (18) sur son côté interne (24) de manière à entourer des chambres de pompe (26). L'élément de rotor externe (22) est connecté par le biais d'un arrangement de couplage (32) à l'élément de rotor interne (12) d'une manière rigide en torsion tout en étant toutefois déplaçable dans une direction radiale.
