Abstract

La présente invention concerne un tiroir à tube articulé appliqué à une pompe à béton à deux cylindres. Suivant l'invention, la portion d'extrémité du tube articulé 14 est montée pivotante dans un plan perpendiculaire aux surfaces d'étanchéité 8, 9 des orifices de rejet 10 et 7 des cylindres 1 et 2 de la pompe. Cette portion d'extrémité est reliée par l'articulation 13 à une partie 12a d'un bras oscillant en deux parties pivotant autour d'une articulation. Le bras oscillant précité est prolongé par un bras de levier 15 à l'extrémité duquel vient en prise un cylindre de pression 16 permettant le mouvement dudit bras oscillant. L'invention assure un fonctionnement efficace et simple aux pompes à béton.
