Abstract
EL INVENTO SE REFIERE A UNA VALVULA DE DESCARGA EN CIRCUITOS HIDRAULICOS, QUE COMPRENDE UN CUERPO DE VALVULA (1) QUE INCLUYE UN ANIMA CIEGA CERRADA POR UNA MEMBRANA (4) Y QUE COMUNICA CON UNA CAMARA DE ENTRADA (7) Y UNA CAMARA DE SALIDA (8) ENTRE LAS CUALES ESTA DISPUESTO UN MIEMBRO DE VALVULA (3) Y UN ASIENTO (2); UN MEDIO FLEXIBLE (5) INSTALADO ENTRE LA MEMBRANA Y EL MIEMBRO DE VALVULA MANTIENE AL MIEMBRO DE VALVULA EN REPOSO EN UNA POSICION CERRADA. DE ACUERDO CON EL INVENTO, LA MEMBRANA ES PLASTICAMENTE DEFORMABLE EN UNA DIRECCION AXIAL. PREFERIBLEMENTE, EL MEDIO FLEXIBLE (R) ES UN MUELLE PRECARGADO, Y HAY DISPUESTA UNA ARANDELA (6) ENTRE LA MEMBRANA Y EL MEDIO FLEXIBLE (5). ESTA VALVULA ES UTIL ESPECIALMENTE PARA MECANISMOS DE DIRECCION DE VEHICULOS.
