Abstract

Pompe à béton du type qui comprend plusieurs cylindres dans lesquels coulissent des pistons à mouvement opposés, une trémie de charge et un distributeur à obturateur oscillant placé devant les cylindres et sous la trémie, le distributeur comprenant un corps qui présente deux orifices d'entrée du beton refoulé, un orifice de sortie 16 et une ouverture d'aspiration, ainsi qu'un obturateur oscillant 13 monté sur un arbre 14 et pouvant prendre deux positions. Suivant l'invention, l'ouverture d'apiration forme deux orifices d'aspiration 37, 38 à chacun desquels est associé une palette supplémentaire 19 ou 20 de l'obturateur 13, la palette 18 de commande balayant par son bord avant l'orifice de sortie 16 qui est ménagé dans une paroi terminale du corps du distributeur, l'arbre 14 est situé au-dessus des axes des cylindres, parallèle et à égale distance de ceux-ci.
