Abstract

Un dispositivo de infusión perfeccionado que comprende un conducto de líquido que va a conectarse a un recipiente alimentador y que está subdividido en una parte superior de conducto y una parte inferior de conducto, entre las cuales se incluye un dispositivo dosificador que comprende una cámara que comunica, por medio de una abertura superior y una abertura inferior, con la parte superior de conducto y la parte inferior de conducto, respectivamente, alojando dicha cámara un cuerpo que puede moverse verticalmente y que consiste, al menos parcialmente, en un material ferromagnético y que cierra la abertura inferior en estado de reposo, disponiéndose de un electroimán que, cuando se aplica al mismo una corriente eléctrica, genera un campo magnético en la cámara que ejerce sobre el cuerpo una fuerza dirigida hacia arriba, caracterizado por que el cuerpo tiene forma esférica, no siendo mayor de una décima parte de su diámetro la distancia en que puede desplazarse en dirección vertical, estando dispuesta una fuente de corriente que está adaptada para suministrar impulsos de corriente triangulares para la excitación del electroimán.
