Abstract

UN CONJUNTO DE ACUMULADOR Y SUMIDERO DE VOLUMEN VARIABLE (50) PARA EL SISTEMA DE FRENOS ANTI-BLOQUEO DE UN VEHICULO, COMPRENDE UN ALOJAMIENTO (52) QUE PRESENTA UN TALADRO ESCALONADO (56). UN PAR DE PISTONES (60, 80) EN FORMA DE U ESTAN DISPUESTOS DENTRO DEL TALADRO ESCALONADO (56), COMPRENDIENDO EL PRIMER PISTON UN PISTON (60) DE ACUMULADOR Y DEFINIENDO CON EL ALOJAMIENTO (52) Y TALADRO ESCALONADO (56) UNA PRIMERA CAMARA (70) QUE CONTIENE UN MEDIO A PRESION. EL SEGUNDO PISTON (80) DEFINE CON EL ALOJAMIENTO (52) Y TALADRO ESCALONADO (56) UNA SEGUNDA CAMARA (90) QUE CONTIENE FLUIDO A PRESION. LOS EXTREMOS ABIERTOS DE LOS PISTONES (60, 80) EN FORMA DE U ESTAN RECIBIDOS UNO DENTRO DEL OTRO Y ESTA DISPUESTO UN RESORTE (95) ENTRE ABERTURAS INFERIORES (62, 82) DE LOS PISTONES (60, 80) PARA OBLIGAR A SEPARARSE A ESTOS ULTIMOS.
