Abstract

DISPOSICION DE VALVULA DE ADMISION DE AIRE A PRESION Y DE ESCAPE PARA MAQUINA DE MOLDEO, ESPECIALMENTE PARA MAQUINAS EXPULSORAS DE MACHOS, EN LA QUE SE HA COLOCADO EN LA UNIDAD EXPULSORA, CONSTITUIDA POR EL RECIPIENTE A PRESION Y EL PISTON DE CONTROL, UNA CAVIDAD DE PRESION POR DEBAJO DEL PISTON DE CONTROL, QUE POSEE AL MENOS DOS ABERTURAS. EN UNA DE LAS ABERTURAS SE HA CONECTADO UNA VALVULA DE VENTILACION RAPIDA. LA OTRA ABERTURA ESTA CONECTADA CON LA CAVIDAD EXPULSORA POR MEDIO DE UN CANAL Y CUBIERTA POR MEDIO DE UN ELEMENTO DE CIERRE HERMETICO. EL ELEMENTO DE CIERRE HERMETICO ESTA CONSTITUIDO POR UN MATERIAL RESISTENTE A LA ABRASION, SE HA CONFIGURADO EN FORMA DE LABIOS Y YACE SOBRE LA ABERTURA EN EL INTERIOR DE LA CAVIDAD A PRESION.DISPOSAL OF A PRESSURE AIR INTAKE AND EXHAUST VALVE FOR A MOLDING MACHINE, ESPECIALLY FOR A MACHINE FOR EXPELLING MACHINES, IN WHICH IT HAS BEEN PLACED IN THE PRESSURE CONTAINER AND THE CONTROL PISTON, A CAVITY PRESSURE BELOW THE CONTROL PISTON, WHICH HAS AT LEAST TWO OPENINGS. IN ONE OF THE OPENINGS A QUICK VENTILATION VALVE HAS BEEN CONNECTED. THE OTHER OPENING IS CONNECTED TO THE EXPELLING CAVITY THROUGH A CHANNEL AND COVERED THROUGH A HERMETIC CLOSING ELEMENT. THE HERMETIC CLOSURE ELEMENT IS CONSTITUTED BY AN ABRASION RESISTANT MATERIAL, IT HAS BEEN CONFIGURED IN THE FORM OF LIPS AND LIES ON THE OPENING INSIDE THE PRESSURE CAVITY.
