Abstract

Perfeccionamientos introducidos en las bombas de émbolo radial; para instalaciones hidráulicas, con varios émbolos suministradoras cargados por resorte y accionados por una excéntrica, los cuales aspiran a través de aberturas practicadas en la pared del émbolo el aceite a presión y lo transportan a través de las partes interiores de los émbolos suministradores y por medio de unos canales de presión, agregados a los mismos, a una cámara de presión, realizada en forma de cámara colectora, estando unida la cámara de presión con un empalme de evacuación y con un dispositivo de válvula que impide el retorno del aceite a presión a los émbolos suministradores, caracterizados porque la primera cámara de presión, que puede ser puesta en comunicación con la cámara interior de los émbolos suministradores, está acoplada una segunda cámara de presión.
