Abstract

EL CILINDRO MAESTRO (30) INCLUYE PISTONES PRIMARIO Y SECUNDARIO (42,52) CADA UNO DE LOS CUALES TIENE UN MIEMBRO DE LA VALVULA DE COMPENSACION DEL CENTRADO (44,60). UN MIEMBRO TOPE O PASADOR (38,40) SE EXTIENDE A TRAVES DE UN AGUJERO (36) DEL CILINDRO MAESTRO (30) CONTIGUO A LOS EXTREMOS DE CADA UNO DE LOS PISTONES (42,52) Y LOS PASADORES (38,40) ESTAN ENGANCHADOS CADA UNO POR VASTAGOS (45,64) DE LOS MIEMBROS DE LA VALVULA EMPUJADOS POR MUELLES (44,60) DE LOS PISTONES PRIMARIO Y SECUNDARIO (42,52). UNA VARILLA DE SALIDA (43) DE UN REFORZADOR DE VACIO (41) AL CUAL ESTA UNIDO EL CILINDRO MAESTRO (30), DISPONE EL PISTON PRIMARIO (52) LIGERAMENTE SEPARADO DEL RESPECTIVO PASADOR (40) EN UNA POSICION DE REPOSO. EL PISTON PRIMARIO (52) INCLUYE UN ASIENTO PARA VALVULA DE CENTRADO DE COMPENSACION AUTOAJUSTABLE (70) LOCALIZADO DENTRO DEL PISTON PRIMARIO (52), SIENDO EL ASIENTO DE LA VALVULA (70) MOVIL SELLANDO Y DESLIZANDO EN RELACION AL PISTON PRIMARIO (52). EL ASIENTO DE LA VALVULA (70) SE PROLONGAA TRAVES UNA ABERTURA POSTERIOR (59) DEL PISTON (52) PARA ENGANCHAR CON EL RESPECTIVO PASADOR (40). EL ENGANCHE DEL ASIENTO DE LA VALVULA (70) Y DEL VASTAGO (64) DEL MIEMBRO DE LA VALVULA (60), ASEGURA QUE LA CABEZA DE LA VALVULA (62) ESTE SIEMPRE POSICIONADA A UNA DISTANCIA PREDETERMINADA (C) DEL ASIENTO DE LA VALVULA (70) EN LA POSICION DE REPOSO DEL PISTON PRIMARIO (52). EL "TACTO" DEL PEDAL DEL FRENO PUEDE SER ESTRECHAMENTE CONTROLADO PARA REDUCIR LA BLANDURA DEL TACTO DEL PEDAL DURANTE LA ACTUACION DEL FRENO POR DISMINUCION DE LAS TOLERANCIAS DE ESCALONADO VERTICAL DENTRO DEL CILINDRO MAESTRO (30), DE TAL MODO QUE EL MIEMBRO DE LA VALVULA (60) DEL PISTON PRIMARIO (52) CIERRE MUY RAPIDAMENTE.
