Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE PURGA (1) PARA EL CARTER DE UN MOTOR DE COMBUSTION INTERNA AL QUE SE HA FIJADO UNA CULATA (2) TAPADA POR UNA CUBIERTA DE CULATA (3). EL DISPOSITIVO DE PURGA (1) PRESENTA UN SEPARADOR DE ACEITE (6), INTEGRADO EN GRAN MEDIDA EN LA CUBIERTA DE CULATA (3) Y PROVISTO DE SINUSOIDES, FORMADO POR UNA PARTE SUPERIOR (9) CONECTADA DE UNA PIEZA CON LA CUBIERTA DE CULATA (3) Y UNA PARTE DE BASE (10). EL SEPARADOR DE ACEITE (6) PRESENTA UNA ENTRADA (14), UN TUBO DE ASPIRACION CONECTADO AL SISTEMA DE ASPIRACION DEL MOTOR DE COMBUSTION INTERNA Y UNA SALIDA DE ACEITE (15). LAS SINUSOIDES DEL SEPARADOR DE ACEITE ESTAN FORMADAS POR ALMAS (11) DE LA PARTE SUPERIOR (6). PARA CONFORMAR UN DISPOSITIVO DE PURGA PARA EL CARTER DE UN MOTOR DE COMBUSTION INTERNA QUE APROVECHE EL ESPACIO DE MONTAJE DISPONIBLE, SEA FACIL Y BARATO DE FABRICAR Y COMODO Y ECONOMICO DE MONTAR, SEGUN LA INVENCION SE PROPONE QUE EL SEPARADOR DE ACEITE PRESENTE UNA CAIDA DE LA ENTRADA A LA SALIDA DE ACEITE EN DIRECCION DE UN EJE LONGITUDINAL DEL MOTOR Y UNA CAIDA EN DIRECCION DE UN EJE TRANSVERSAL DEL MOTOR Y QUE LA SALIDA DE ACEITE DEL SEPARADOR ABARQUE UN CONDUCTO DE SALIDA DE ACEITE DE INMERSION EN UNA PETACA DE ACEITE FORMADA POR PRESAS CONFORMADAS EN LA CULATA.THE INVENTION REFERS TO A PURGE DEVICE (1) FOR THE CARTER OF AN INTERNAL COMBUSTION ENGINE TO WHICH A HEAD (2) HAS BEEN FIXED, COVERED BY A HEAD COVER (3). THE PURGE DEVICE (1) PRESENTS AN OIL SEPARATOR (6), INTEGRATED IN GREAT MEASURE IN THE HEAD COVER (3) AND PROVIDED WITH SINUSOIDS, FORMED BY A TOP PART (9) CONNECTED TO A PART WITH THE HEAD COVER (3) AND A BASE PART (10). THE OIL SEPARATOR (6) PRESENTS AN INPUT (14), AN ASPIRATION TUBE CONNECTED TO THE INTERNAL COMBUSTION ENGINE SUCTION SYSTEM AND AN OIL OUTPUT (15). THE OIL SEPARATOR SINUSOIDS ARE FORMED BY SOULS (11) OF THE UPPER PART (6). TO CONFORM A PURGE DEVICE FOR THE CARTER OF AN INTERNAL COMBUSTION ENGINE THAT TAKES ADVANTAGE OF THE AVAILABLE MOUNTING SPACE, BE EASY AND CHEAP OF MANUFACTURING AND COMFORTABLE AND ECONOMIC TO ASSEMBLE, AS THE INVENTION IS PROPOSED FOR THE OIL SEPARATOR TO PRESENT THE ENTRY TO THE OIL OUTPUT IN THE DIRECTION OF A LONGITUDINAL AXLE OF THE ENGINE AND A DROP IN THE DIRECTION OF A TRANSVERSAL AXLE OF THE ENGINE AND THE OIL OUTPUT OF THE SEPARATOR EMBRACE AN OIL OUTPUT DUCT IN A OIL PETACA FORMED BY DAMS CONFORMED IN THE HEAD.
