Abstract
Perfeccionamientos en bombas de desplazamiento positivo para la descarga simultánea por separado de cantidades desiguales predeterminada de por lo menos dos líquidos viscosos, caracterizados porque se dota a cada bomba de un dispositivo de transmisión dispuesto para producir el movimiento alternativo simultáneo de por lo menos dos pistones de bombeo, deslizándose cada pistón de bombeo en un cilindro de bombeo respectivo, conectándose cada cilindro de bombeo a una válvula respectiva que desemboca de un modo selectivo en una boca de entrada o una boca de salida de líquido respectivo por lo que, en la práctica, el movimiento alternativo de los pistones de bombeo dentro de los cilindros de bombeo produce bombeo simultáneo de cantidades predeterminadas desiguales de líquidos desde las bocas de entrada hasta las bocas de salida.
