Abstract
UN DIAFRAGMA (50) PARA ACTIVADORES DE FRENO DE MUELLE (40) QUE INCLUYE UNA ABERTURA (52) QUE ALOJA UN ELEMENTO DE SUJECION ESTRIADO (54) DE MANERA QUE EL DIAFRAGMA SE ENCUENTRA FIJADO DIRECTAMENTE A UNA VARILLA DE EMPUJE. DE ESTA MANERA, LA DESALINEACION ENTRE LA VARILLA Y EL DIAFRAGMA SE ELIMINA. PARA SOBREPONERSE A CUALQUIER DERRAME A TRAVES DE LA ABERTURA DEL DIAFRAGMA, ESTE ESTA FORMADO CON PUNTOS DE SELLAJE (60) COMPRIMIDOS POR EL ELEMENTO DE SUJECION PARA CONSEGUIR UN SELLAJE. PREFERIBLEMENTE, LAS PLANCHAS DEL DIAFRAGMA (56,58), SE ALOJAN EN CADA LADO DEL MISMO (50), Y LOS PUNTOS DE SUJECION SE ENCUENTRAN COMPRIMIDOS MEDIANTE LOS ELEMENTOS DE SUJECION (54) PARA CONSEGUIR UN SELLAJE ENTRE EL ELEMENTO DE SUJECION Y LAS PLANCHAS DEL DIAFRAGMA. SE CONSIGUE ASI UN SELLAJE ADECUADO, MIENTRAS SE PERMITE QUE LA CONEXION DIRECTA DEL DIAFRAGMA CON LA VARILLA DE EMPUJE SE REALICE MEDIANTE UN ELEMENTO CONECTOR ESTRIADO. LA PLANCHA DE DIAFRAGMA SOBRE EL LADO DEL MUELLE ENERGETICO DEL DIAFRAGMA SEEXTIENDE HACIA ARRIBA HASTA UN RECESO EN LA PLANCHA DEL MUELLE (26) Y SE ENCUENTRA EN CONTACTO FACIAL EN UNA DIRECCION AXIAL CON UNA SUPERFICIE DE LA PLANCHA DE MUELLE CUANDO EL MUELLE (28) ES ACTIVADO. AL MISMO TIEMPO, SE PRODUCE UN VACIO CUANDO EL MUELLE ES COMPRIMIDO, DE MANERA QUE LA DESALINEACION DE LA VARILLA DE EMPUJE (46) DEBIDO A LAS TOLERANCIAS DE FABRICACION TAMBIEN SE ELIMINAN. ESTE CONTACTO RESISTE LA DESALINEACION ENTRE LA PLANCHA DE MUELLE ENERGETICO (26) Y LA PLANCHA DEL DIAFRAGMA, Y CONSECUENTEMENTE EL DIAFRAGMA. EXISTE UN PEQUEÑO VACIO RADIAL ENTRE LA PERIFERIA EXTERNA DE LA PLANCHA DEL DIAFRAGMA Y LA PLANCHA DEL MUELLE DE MANERA QUE LOS DOS ELEMENTOS "FLOTAN LIBREMENTE" Y PUEDEN POSEER UNA PEQUEÑA CANTIDAD DE AJUSTE RELATIVO.
