Abstract
LA INVENCION ESTA RELACIONADA CON UNA MAQUINA QUE LLEVA FLUIDOS, ESPECIALMENTE UNA BOMBA, CON UN ELEMENTO ROTATORIO (8) QUE GIRA EN UNA PARTE FIJA DE LA CARCASA (16) DENTRO DE UN INTERSTICIO ANULAR, SEPARANDO LA PARTE FIJA DE LA CARCASA UNA CAMARA INTERIOR (11) QUE PRESENTA UNA MAYOR PRESION DE PRODUCTO DE UNA CAMARA EXTERIOR (18) CON UNA PRESION MAS BAJA, EN LA QUE SE ALOJA EL ELEMENTO ROTATORIO EN UN COJINETE EXTERIOR (13) IMPERMEABILIZADO FRENTE A LA CAMARA INTERIOR POR MEDIO DE UN SISTEMA DE OBTURACION. PARA MEJORAR LA OBTURACION SE PROPONE SEGUN LA INVENCION QUE EL INTERSTICIO ANULAR (17) SE FORME ENTRE DOS CAPSULAS DE COJINETE DESLIZANTE (19) HECHAS DE MATERIALES EXTREMADAMENTE DUROS Y RESISTENTES AL DESGASTE, QUE DE ACUERDO CON EL PRINCIPIO DE ACCION DE UN COJINETE DESLIZANTE RADIAL CREAN UNA PRIMERA FASE DE REDUCCION DE LA PRESION A LA QUE SIGUE, EN DIRECCION AXIAL, UN SISTEMA DE RETROCESO (21) QUE RECONDUCE LA FUGA DE ESTA PRIMERA FASE DE OBTURACION AL PROCESO DE TRANSPORTE DE LA MAQUINA, DETRAS DE LA CUAL SE PREVE EN DIRECCION AXIAL UNA SEGUNDA FASE DE OBTURACION (22) CONFIGURADA COMO SIMPLE JUNTA EN FORMA DE UN ANILLO DE OBTURACION LABIAL Y/O DE UNA SIMPLE JUNTA DE ANILLO DESLIZANTE.
