Abstract

Ce transporteur est du type comportant un réservoir de béton frais associé à un tuyau souple dans une extrémité duquel le béton est introduit et refoulé jusqu'à son autre extrémité située à l'endroit où le béton doit être déversé D'une part, le réservoir de béton est une trémie, et d'autre part le fond de cette trémie communique avec l'extrémité amont du tuyau souple par l'intermédiaire d'un compartiment faisant office de sas et par conséquent équipe de deux clapets de fermeture commandes, l'un d'entrée et l'autre de sortie, ce compartiment étant en outre relié par l'intermédiaire d'un système de valve à une canalisation d'air comprimé et à un orifice de mise à l'air libre tandis qu'un organe sensible à la pression est associé au dit compartiment pour commander en temps utiles l'ouverture ou la fermeture de la vanne d'air comprimé, l'ouverture ou la fermeture du clapet de sortie et l'ouverture ou la fermeture du clapet d'entrée.
