Abstract

VALVULA DE MANDO HIDRAULICO PARA SISTEMAS DE DIRECCION ASISTIDA QUE REDUCE LA ACCION AMPLIFICADORA QUE ENMASCARA LOS ESFUERZOS DE FRICCION AL CONDUCIR EN LINEA RECTA VEHICULOS. CONSISTE EN QUE EL ARBOL (2) ESTA ACOPLADO A LA VALVULA (3) DE ARBOL QUE FORMA EL ELEMENTO INTERIOR DE UNA VALVULA ROTATIVA; LA VALVULA DE ARBOL (3) SE AJUSTA AL PIÑON MANGUITO (4) CON UNA ROTACION RELATIVA DE 7G EN CADA SENTIDO DE LA POSICION CENTRAL, AMBOS ESTAN CENTRADOS ELASTICAMENTE EN UNA POSICION NEUTRAL POR UNA BARRA (5) DE TORSION FIJADA EN LOS EXTREMOS SUPERIOR E INFERIOR AL MANGUITO (4) Y A LA VALVULA (3). EL MANGUITO (4) ESTA MONTADO EN LA CARCASA (8) Y CONSTA DE UNA SERIE DE JUNTAS (9) QUE SEPARAN UNA SERIE DE RANURAS CIRCUNFERENCIALES (10) QUE COMUNICAN A TRAVES DE CONDUCTOS EXTERNOS (I Y R) DE LA BOMBA (1) Y DE MODO PARECIDO A TRAVES DE CONDUCTOS (CL Y CR) A LOS EXTREMOS OPUESTOS DEL SERVOCILINDRO (11).
