Abstract

DIRECCION POR SERVOMECANISMO, ESPECIALMENTE PARA AUTOMOVILES. COMPRENDE UN EMBOLO DE TRABAJO (2) SITUADO EN UNA CAJA DE ENGRANAJE DE DIRECCION (3) Y, POR OTRA PARTE, A TRAVES DE UNA SERIE DE ESFERAS (4), CON UN TORNILLO SIN FIN (5). EL HUSILLO DE DIRECCION (7), UNIDO AL TORNILLO SIN FIN (5) A TRAVES DE LA BARRA DE TORSION (6), LLEVA UN DISTRIBUIDOR GIRATORIO (8) QUE ACTUA CONJUNTAMENTE CON UNA CAJA CILINDRICA (10), FORMANDO UNA VALVULA DE DISTRIBUCION. MEDIANTE LA CITADA VALVULA, EL LIQUIDO PROCEDENTE DE UNA TOMA DE BOMBA (15), PUEDE PASAR A UNA DE LAS DOS CAMARAS DE PRESION (12, 13), SITUADAS EN LOS EXTREMOS DEL EMBOLO DE TRABAJO (2). ENTRE LAS DOS CITADAS CAMARAS DE PRESION (12, 13), Y ATRAVESANDO LONGITUDINALMENTE EL CITADO EMBOLO, EXISTEN DOS TALADROS DE PASO (34, 34A), EN CADA UNO DE LOS CUALES SE HA EMPLAZADO UNA VALVULA DE DESCONEXION QUE, AL MISMO TIEMPO, ACTUA COMO VALVULA LIMITADORA DE PRESION.
