Title (EN) A REGENERATIVE FLUID PUMP AND STATOR FOR THE SAME
(FR) POMPE A FLUIDE REGENERATIVE ET STATOR ASSOCIE
Abstract: front page image
(EN)A regenerative fluid pump (10) comprises a rotor having rotor blades for compressing fluid on a fluid flow path extending between a pump inlet (12) and a pump outlet (14), and a stator comprising a plurality of concentric channels (16) each of which comprises: a pumping channel portion (18) along which said rotor blades move for compressing said fluid between an inlet and an outlet of the pumping channel; and a stripper channel portion (20) which allows movement of said rotor blades from said outlet to said inlet of the pumping channel portion. Diversion channels (22) divert fluid between the pumping channel portions. The pumping channel portions (18) of any two directly adjacent concentric channels (16) do not circumferentially overlap so that the stripper channel portions (20) are directly adjacent the pumping channel portions (18), over the circumferential extent of the pumping channel portions.
(FR)L'invention concerne une pompe (10) à fluide régénérative comprenant des ailettes de rotor pour comprimer le fluide sur un trajet d'écoulement de fluide s'étendant entre une admission (12) et une sortie (14) de pompe, et un stator comprenant plusieurs canaux concentriques (16), chacun comprenant une partie canal de pompage (18) le long de laquelle lesdites ailettes se déplacent pour comprimer le fluide entre une admission et une sortie du canal de pompage; et une partie canal séparateur (20) qui permet le déplacement desdites ailettes de ladite sortie à ladite admission de la partie canal de pompage. Des canaux de dérivation (22) dévient le fluide entre les parties canal de pompage. Les parties canal de pompage (18) de deux canaux concentriques (16) quelconques directement contigus ne se chevauchent pas de sorte que les parties canal séparateur (20) jouxtent directement les parties canal de pompage (18), dans le prolongement périphérique des parties canal de pompage.
