Abstract

LA INVENCION SE REFIERE A UN RECEPTACULO PARA LA ALIMENTACION DE MATERIAL PARA BOMBAS DE FLUIDOS VISCOSOS DE DOS CILINDROS, CON UN DESVIO DE TUBO CONCEBIDO COMO TUBO BASCULANTE (34). EN LA PARED FRONTAL (12) DEL RECEPTACULO PARA LA ALIMENTACION DEL MATERIAL (10), SE ENCUENTRAN DOS ABERTURAS (22) EN EL LADO DE LA BOMBA QUE CONDUCEN A LOS CILINDROS DE ALIMENTACION (26), MIENTRAS QUE EN LA PARTE TRASERA OPUESTA (14) SE HAN DISPUESTO RESPECTIVAMENTE DOS ABERTURAS DE SALIDA (28) QUE CONDUCEN RESPECTIVAMENTE A UN RACOR (32) Y A UNA TUBERIA DE ALIMENTACION. EL TUBO BASCULANTE (34) CONCEBIDO COMO TUBO DE PASO RECTO ES BASCULADO DE FORMA ALTERNATIVA DELANTE DE AMBAS ABERTURAS (22, 28) EN EL LADO DE SALIDA Y EN EL LADO DE LA BOMBA Y UNE ESTAS ENTRE SI EN PAREJAS. EL TUBO BASCULANTE ESTA EQUIPADO EN SUS DOS EXTREMOS CON UN ANILLO OBTURADOR Y UN ANILLO DE DESGASTE (42) RESPECTIVAMENTE, EL CUAL BAJO LA ACCION DE LA PRESION DEL FLUIDO CONTRA LAS ABERTURAS VECINALES, ES FIJABLE Y AJUSTABLE DE FORMA AUTOMATICA. ADEMAS, EL TUBO BASCULANTE ESTA DOTADO EN SUS EXTREMOS DE SALIDA CON DOS TAPAS (40), QUE SOBRESALEN RADIALMENTE HACIA LOS LADOS, LAS CUALES CIERRAN LAS ABERTURAS DE SALIDA ABIERTAS (28) HACIA EL INTERIOR DEL RECEPTACULO INHIBIENDO EL RETROCESO.
