Abstract

L’invention concerne une pompe volumétrique à lobes (10) comprenant :- un stator (11) comportant une paroi interne définissant un volume statorique ;- un rotor (14) mobile en rotation à l’intérieur du volume statorique ; le rotor (14) comportant au moins deux lobes (15) configurés pour définir un volume de pompage (Vp) ; et- un clapet (16) monté au niveau de la cheminée d’extraction (13) de sorte à coopérer avec les lobes (15) pour contraindre les fluides, présents dans le volume de pompage (Vp), à être déplacés dans une cheminée d’extraction (13) ;les lobes (15) présentant une extrémité radiale (18-19) en forme d’au moins un chevron de sorte que la mise en communication hydraulique du volume de pompage (Vp) avec la cheminée d’extraction (13) soit progressive, le clapet (16) présentant une forme d’au moins un chevron complémentaire avec celle des lobes (15). Figure pour l’abrégé : Fig 1The invention relates to a positive displacement lobe pump (10) comprising: - a stator (11) comprising an internal wall defining a stator volume; - a rotor (14) movable in rotation inside the stator volume; the rotor (14) comprising at least two lobes (15) configured to define a pumping volume (Vp); and- a valve (16) mounted at the level of the extraction chimney (13) so as to cooperate with the lobes (15) to force the fluids, present in the pumping volume (Vp), to be moved in a chimney extraction (13); the lobes (15) having a radial end (18-19) in the shape of at least one chevron so that the hydraulic communication of the pumping volume (Vp) with the extraction chimney (13) is progressive, the valve (16) having a shape of at least one chevron complementary to that of the lobes (15).
