Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA EL CONTROL DE LA PRESION EN UN MATERIAL VISCOSO QUE FLUYE, SIENDO CARACTERIZADO EL DISPOSITIVO POR MEDIO DE: UNA ENTRADA (8A) A TRAVES DE LA CUAL EL MATERIAL FLUYE DENTRO DEL DISPOSITIVO, UN CILINDRO (9) CON CAPACIDAD DE SOPORTADO DE UN VOLUMEN PARTICULAR DEL MATERIAL QUE FLUYE A TRAVES DE LA ENTRADA (8A), UN INMERSOR (11) QUE DISPONE DE UNA ABERTURA (11D) Y ESTA INSTALADO PARA MOVERSE DENTRO DEL CILINDRO (9), CAMBIANDO LA CAPACIDAD DEL CILINDRO (9) CUANDO SE MUEVE, CON UN RECEPTACULO (11A) QUE ESTA FIJADO POR ENCIMA DE LA ABERTURA (11D) EN EL INMERSOR (11) Y CONECTADO A LA ENTRADA DE TAL MODO, QUE EL MATERIAL FLUYE A PARTIR DE LA ENTRADA (8A) A TRAVES DEL RECEPTACULO (11A) Y A TRAVES DE LA ABERTURA (11D) EN EL INMERSOR (11) DENTRO DEL CILINDRO (9), CON UNA SALIDA (10A) CONECTADA AL CILINDRO (9) Y A TRAVES DE LA CUAL EL MATERIAL SE DESCARGA A PARTIR DEL DISPOSITIVO. DE ACUERDO CON LA INVENCION, LA ENTRADA (8A), EL CILINDRO (9) Y EL RECEPTACULO (11A) PUEDEN SER DE FORMA TUBULAR EN SU DISEÑO Y EL RECEPTACULO (11A) PUEDE DESLIZARSE DE FORMA TELESCOPICA POR ENCIMA DE LA ENTRADA (8A) CUANDO SE MUEVE EL INMERSOR (11).
