Abstract

L'invention concerne une pompe à bouillie comportant des composants qui incluent une enveloppe principale (120) de pompe, une enveloppe côté avant, une enveloppe côté arrière et un rouet. L'enveloppe principale de pompe comporte une formation continue (156) dépassant d'une surface intérieure (152) d'un passage (151) de refoulement et d'une partie (145) de surface périphérique d'une chambre (142) de pompage, la formation (156) présentant une première extrémité (157) située à l'intérieur du passage (151) de refoulement et espacée par rapport à un orifice (154) de sortie, et une deuxième extrémité (158) située dans la chambre (142) de pompage. L'enveloppe côté avant (200) comprend une formation (220) de guidage sur une surface intérieure (218) d'un passage (212) d'admission, la formation (220) de guidage s'étendant d'une extrémité (214) d'entrée du passage (212) d'admission à une extrémité (216) de sortie et comprenant une partie (222) d'extrémité de tête à l'extrémité (214) d'entrée du passage (212) et une partie (224) d'extrémité de queue à l'extrémité (216) de sortie, la formation (220) de guidage comprenant en outre une surface (226) de guidage s'étendant entre la partie (222) d'extrémité de tête et la partie (224) d'extrémité de queue. L'enveloppe arrière comporte une pluralité d'aubes (330) sur une face arrière (308), les aubes (330) s'étendant de façon généralement radiale et comprenant un bord intérieur (313) et un bord extérieur (315), le bord intérieur (313) étant adjacent à la paroi périphérique (312) d'un passage (310). Le rouet est doté de deux formations ou nervures surélevées (435, 436) sur une partie (430) de nez ou d'œil, l'une des formations ou nervures (435) s'étendant à partir du bord d'attaque (420) d'une aube (410) de pompage dans la région où le bord d'attaque est adjacent à un carénage arrière (402) par-dessus la partie de nez ou d'œil et passant par le sommet (440) jusqu'à un bord d'attaque (422) d'une aube (412) de pompage disposée de façon opposée dans la région où le bord est adjacent au carénage arrière (402).
