Abstract
EL SISTEMA ESTA CONSTITUIDO POR UNA VALVULA (12) CON UNA CAJA (13), CUYA TARA VARIA AUTOMATICAMENTE CON LA PRESION DE HINCHADO DE UN ACUMULADOR (4) A TRAVES DE UNA LLAVE AUTOMATICA PILOTADA (17) QUE ENLAZA EL ACUMULADOR (4) A LA CAMARA DE LA VALVULA (12), SITUADA DETRAS DE LA CAJA (13). LA LLAVE ESTA NORMALMENTE ABIERTA, CUANDO LA PRESION DEL GATO (5) ES IGUAL A LA PRESION DE HINCHADO DEL ACUMULADOR, Y SE CIERRA, CUANDO LA PRESION DEL GATO (5) AUMENTA COMO CONSECUENCIA DEL EMPUJE DE LA REJA DEL ARADO SOBRE UN OBSTACULO, MANTENIENDO ASI LA PRESION DE HINCHADO TRAS LA CAJA (13) QUE SE DESPLAZA COMO RESULTADO DE LA APERTURA DE LA VALVULA (10) PARA UNA PRESION DADA.
