Abstract

SERVOMOTOR CON DEPRESION DE ASISTENCIA AL FRENADO. LA PARTE TUBULAR (9) DEL CUBO (7) DEL CONJUNTO DE PISTON (5), QUE CONTIENE LA VALVULA DE DISTRIBUCION (8), SOPORTA UN CONJUNTO (200) DE UN CASQUILLO DE GUIA (21) Y DE UNA JUNTA DE ESTANQUIDAD (20) QUE COOPERA CON LA PARED INTERNA DE UNA PIEZA TUBULAR (22) MONTADA, POR EJEMPLO ENGASTADA, EN UNA CHIMENEA CENTRAL (23) DE LA COQUILLA POSTERIOR (2) DE LA CARCASA (1) DEL SERVOMOTOR Y QUE PRESENTA UNA PRIMERA PARTE DE EXTREMIDAD (26) QUE SE EXTIENDE EN SALIENTE AXIALMENTE EN LA CAMARA DE TRABAJO POSTERIOR (4) DEL SERVOMOTOR. VENTAJOSAMENTE LA PIEZA TUBULAR (22) COMPRENDE UNA SEGUNDA PARTE DE EXTREMIDAD (37) QUE FORMA UN TOPE (36) PARA UN ORGANO DE TOPE (31) ASOCIADO CON EL VASTAGO DE ENTRADA (12) Y QUE FORMA APOYO PARA EL RESORTE DE RECUPERACION (30) DEL VASTAGO DE ENTRADA (12). CON UNA DISPOSICION DE ESTE TIPO, LA SUPERFICIE DE DESLIZAMIENTO, UNIDAS SOBRE LA ESTRUCTURA TUBULAR, ESTA COMPLETAMENTE INTEGRADA EN EL SERVOMOTOR, LO QUE EVITA ADEMAS TENER QUE RECURRIR A MEDIOS DE PROTECCION ESPECIFICOS ADICIONALES, Y EL CUBO DE PISTON, UNIDO PUEDE REALIZARSE, AL MENOS EXTERIORMENTE, CON UNA PRECISION MENOS RIGUROSA.
