Abstract

SE PRESENTA UNA BOMBA DE MATERIAS CONSISTENTES CON CILINDROS DE TRANSPORTE DISPUESTOS PREFERENTEMENTE PARALELOS POR PAREJAS QUE ASPIRAN Y TRANSPORTAN DE FORMA ALTERNATIVA Y DISPONE DE UN CURSOR, QUE GIRA ALREDEDOR DEL EJE DE UN CANAL CENTRAL. EN CADA PAR DE CILINDROS DE TRANSPORTE CONECTA DE FORMA ALTERNATIVA POR MEDIO DE UN CANAL DE DOBLE VIA EL CILINDRO CON UNA CONDUCCION DE TRANSPORTE COLOCADA FIJA A TRAVES DE UN CANAL CENTRAL ARTICULADO, MIENTRAS QUE AL MISMO TIEMPO UN SEGUNDO CANAL DE DOBLE VIA SE QUEDA ESTANCO BAJO LA LIBERACION DE LOS CILINDROS DE TRANSPORTE DE ASPIRACION SOBRE LA SUPERFICIE DE ESTANQUEIDAD DE MANDO DISPUESTA EN CADA CANAL DE DOBLE VIA, QUE ESTA FORMADA SOBRE LA PARED INTERIOR DE UNA CARCASA DEL CURSOR. CON ELLO FLUYE EL MATERIAL CONSISTENTE Y SE MUESTRA UNA ABERTURA PARA EL CILINDRO DE TRANSPORTE, CON LO QUE SE FORMAN EN LA MISMA LONGITUD LA MISMA PRESION EN LOS CANALES DE DOBLE VIA. DE ACUERDO CON ESTE DESCUBRIMIENTO SE PROPONE QUE LOS CANALES DE DOBLE VIA (7, 8) ESTEN ALINEADOS ESENCIALMENTE Y SE CONECTEN CON EL CANAL CENTRAL (9) EN FORMA DE ANGULO RECTO Y QUE LAS SUPERFICIES DE ESTANQUEIDAD DE MANDO (18, 20) DE LA CARCASA DEL CURSOR (21) SE ENCUENTREN CURVADAS DE FORMA CILINDRICA.A PUMP OF MATERIALS CONSISTING WITH TRANSPORTATION CYLINDERS IS PRESENTED, PREFERABLY PARALLEL ARRANGED BY COUPLES THAT ASPIRATE AND TRANSPORT ALTERNATIVELY AND HAVE A CURSOR, WHICH TURNS AROUND THE AXIS OF A CENTRAL CHANNEL. AT EACH PAIR OF TRANSPORTATION CYLINDERS IT ALTERNATIVELY CONNECTS THROUGH A DOUBLE VIA CHANNEL THE CYLINDER WITH A FIXED POSITIONED TRANSPORT PIPING THROUGH A CENTRAL ARTICULATED CHANNEL, WHILE AT THE SAME TIME A SECOND DOUBLE VIA CHANNEL IS STAYING UNDER THE RELEASE OF THE SUCTION TRANSPORTATION CYLINDERS ON THE CONTROL SEALING SURFACE PROVIDED IN EACH DOUBLE-WAY CHANNEL, WHICH IS FORMED ON THE INNER WALL OF A CURSOR HOUSING. THEREFORE, THE CONSISTENT MATERIAL FLOWS AND AN OPENING IS SHOWN FOR THE TRANSPORT CYLINDER, WHICH FORMS THE SAME PRESSURE IN THE DOUBLE-WAY CHANNELS. IN ACCORDANCE WITH THIS DISCOVERY IT IS PROPOSED THAT THE DOUBLE-WAY CHANNELS (7, 8) ARE ESSENTIALLY ALIGNED AND CONNECTED TO THE CENTRAL CHANNEL (9) IN THE FORM OF A RIGHT ANGLE AND THAT THE CONTROL WATERTIGHT SURFACES (18, 20) OF THE CURSOR HOUSING (21) IS CURVED IN A CYLINDRICAL FORM.
