Abstract

Perfeccionamientos introducidos en una bomba de doble cilindro, especialmente para transportar hormigón desde un recipiente de reserva con dos orificios que conducen a los cilindros transportadores, delante de los cuales orificos bascula un tubo distribuidor propulsado, con un extremo que está hermetizado con ayuda de una placa de gafas fija y con un anillo para desgaste dispuesto axialmente, preferiblemente reajustable, caracterizados porque el anillo para desgaste está apoyado en un dispositivo tensor y porque el extremo de tubo y el anillo para desgaste están dispuestos de modo movible uno con relación al otro y hermetizados mutuamente.
