Abstract
SE PROPONE UNA VALVULA DE REGULACION DE PRESION, ESPECIALMENTE PARA LA REGULACION DE PRESION EN EL CARTER. ESTA VALVULA REGULADORA DE PRESION SE COMPONE DE UNA CARCASA EN FORMA DE OLLA CON UNA PARTE INFERIOR Y UNA CUBIERTA DE CARCASA, CON LO QUE UNA MEMBRANA (14) SE ENCUENTRA ENTRE AMBAS PIEZAS. EN LA MEMBRANA SE ENCUENTRA DISPUESTA UNA PIEZA (26) CILINDRICA HUECA, QUE RODEA UNA VALVULA INTERMEDIA. ESTA VALVULA INTERMEDIA SE MANTIENE EN SU POSICION DE REPOSO POR MEDIO DE UN RESORTE A COMPRESION (24). LA MEMBRANA SE MUEVE SOBRE UN SEGUNDO RESORTE A COMPRESION (25) EN UNA POSICION SUPERIOR DE REPOSO. EN UNA DEPRESION EN EL TUBO DE ASPIRACION, QUE SOBREPASA UN VALOR LIMITE DETERMINADO EL RESORTE (25) CIERRA EN CONTRA DE LA FUERZA DE RESORTE LA PRIMERA ABERTURA DE LA VALVULA ENTRE EL ASIENTO DE VALVULA (17) Y LA PLACA (18). EN ESTA POSICION DE LA VALVULA SE CONDUCEN LOS SOPLADOS DEL CARTER A TRAVES DE LA ABERTURA DE VALVULA (20). SI LA DEPRESION DEL TUBO DE ASPIRACION SE ELEVA AUN MAS, ENTONCESLA MENBRANA (14) SE MUEVE EN DIRECCION DE LA ABERTURA DE VALVULA (20) Y CIERRA TAMBIEN ESTA ABERTURA DE VALVULA EN UNA DEPRESION MAXIMA ADMISIBLE. ESTA VALVULA EN DOS ETAPAS ESTA CONSTRUIDA DE FORMA ESPECIALMENTE COMPACTA Y AHORRA ESPACIO PUDIENDO SER AJUSTADA EN CASO NECESARIO A TRAVES DE LAS DIMENSIONES DEL RESORTE A PRESION DE LA RELACION DE LA SECCION TRANSVERSAL SOBRE UN DETERMINADO LIMITE DE PRESION.
