Abstract

DISPOSITIVO DE VALVULAS DE CONTROL DE LA PRESION PARA LOS SISTEMAS DE FRENO HIDRAULICO CON CIRCUITO DOBLE. ESTA FORMADO POR DOS VALVULAS DE CONTROL (2, 2'') DISPUESTAS PARALELAMENTE UNA AL LADO DE LA OTRA EN UN CUERPO DE VALVULAS. CADA UNA DE ELLAS ESTA ASIGNADA A UN CIRCUITO DE FRENO Y POSEE UN PISTON (7, 7'') DE CONTROL INDEPENDIENTE ENTRE LA CAMARA DE ENTRADA (10, 10'') Y LA DE SALIDA (11, 11''). ESTOS PISTONES SE ENCUENTRAN SOMETIDOS A UNA FUERZA DE CONTROL CONJUNTA QUE ACTUA SOBRE ELLOS A TRAVES DE UN DISTRIBUIDOR DE PRECARGADO INTERMEDIO. ENTRE LA CAMARA DE SALIDA DE UNO DE LOS CIRCUITOS DE FRENO Y LA DEL OTRO HAY DISPUESTO UN MEDIO DE EQUILIBRADO HIDRAULICO DE LAS PRESIONES DE SALIDA.
