Abstract

LA INVENCION SE REFIERE A UNA CULATA, EN DONDE LA ZONA (5) PROXIMA A LA DESEMBOCADURA DE UNO O MULTIPLES CANALES (3) DE CAMBIO DE GASES ESTA FORMADA MEDIANTE UNA APLICACION (6'''') QUE SE EXTIENDE DE MODO COAXIAL CON RESPECTO A LA VALVULA (7) DE CAMBIO DE GAS. CON ELLO LA ZONA (5) PROXIMA A LA DESEMBOCADURA DEL CANAL (3) PUEDE SER ELABORADA DE FORMA MUY EXACTA Y SIN EMBARGO DE COSTE MUY ADECUADO, POR EJEMPLO MEDIANTE SINTERIZADO DE LA APLICACION (6''''). LA APLICACION (6'''') FORMA TAMBIEN LA GUIA (12'') DE VALVULA. SOBRE LA APLICACION (6) SE APOYA EL RESORTE (20) DE VALVULA. CON ELLO ES POSIBLE EL MONTAJE PREVIO DE UN MODULO DE VALVULA FUERA DE LA CULATA, QUE ABARCA LA VALVULA (7) DE CAMBIO DE GAS, EL RESORTE (20) DE VALVULA, EL PLATO (21) DE RESORTE, LA CUÑA (22) DE PLATO DE RESORTE, LA ESTANQUEIDAD DE VASTAGO DE VALVULA Y EVENTUALMENTE EL ANILLO (17) DE ASIENTO DE VALVULA. CON ELLO SE CONSIGUEN JUNTO A UNA GEOMETRIA DE CANAL EXACTA CON VENTAJA ADICIONAL UNA REDUCCION DE COSTES EN EL MONTAJE DELA CULATA DE CILINDRO.
