Abstract

DISPOSITIVO DE CONTROL DE PRESION PARA SISTEMAS DE FRENO DE DOBLE CIRCUITO. DOS VALVULAS (2, 3) FORMAN PARTE DE UN CUERPO (1) Y COMPRENDEN, RESPECTIVAMENTE, ENTRADAS (4, 6), SALIDAS (5, 7) Y PISTONES DE CONTROL (8, 19) CON JUNTAS DE ESTANQUIDAD HERMETICAS (13, 21). LOS EMBOLOS DE LOS PISTONES (8, 19), DELIMITAN CAMARAS (14, 12) COMUNICADS POR RANURAS (15). CUANDO, AL AUMENTAR LA PRESION, LOS PISTONES SE DESPLAZAN HACIA ARRIBA Y EL BORDE (17, 20) DEL MANGUITO DE CIERRE HERMETICO (9) SOBREPASA EL EXTREMO DE LAS RANURAS (15), LAS CAMARAS (14, 16) QUEDAN AISLADAS, POR LO QUE AL AUMENTAR LA PRESION (P1) AUMENTARA MAS LENTAMENTE LA PRESION (P2). UNA CHAPA (23), FIJADA AL CUERPO MEDIANTE TORNILLOS (24, 25), SOPORTA UN EJE (26) CON PALANCAS INCLINABLES (27, 28) EN CADA UNO DE SUS EXTREMOS, RESPECRTIVAMENTE. CADA PALANCA ESTA PROVISTA DE UN MIEMBRO (29, 30) A TOPE CON EL RESSPECTIVO PISTON (8, 19). LOS CITADOS MIEMBROS (29, 30) SON PRESIONADOS POR LA ACCION DEL EJE (26) DISEÑADO COMO BARRA DE TORSION, ESTANDO EL PUNTO DE CAMBIO PARA OPERACON NORMAL DETERMINADO POR ELLO.
