Abstract

CILINDRO HIDRONEUMATICO DE REGULACION PROGRESIVA DEL DESPLAZAMIENTO LONGITUDINAL. EL PISTON (4) DIVIDE A LA CAVIDAD INTERNA DEL CILINDRO EN DOS SUBCAVIDADES (LA 9 Y LAS SEÑALADAS POR 10, 11 Y 7). EL VOLUMEN DE COMPENSACION (7) PUEDE COMPRIMIRSE ELASTICAMENTE CONTRA LA PARED TERMINAL. LAS CAVIDADES (10, 11) CONTIENEN LIQUIDO, Y SE INTERCONECTAN CON LA CAVIDAD SECUNDARIA (9) MEDIANTE UN DISPOSITIVO DE PASO (5). UN DISPOSITIVO DE FLUJO PASANTE REGULADO (16) INTERCONECTA LOS VOLUMENES SECUNDARIOS (11 Y 10). EL VOLUMEN DE COMPENSACION ELASTICA (7) INCLUYE UN PISTON SEPARADOR ANULAR (8) EN CIERRE HERMETICO CON LA CARA INTERNA DE LA CAJA (1) Y CON EL VASTAGO DE PISTON (3). EXISTEN DISTINTAS REALIZACIONES EN CUANTO AL DISPOSITIVO DE FIJACION A LA TRACCION QUE IMPIDE LA EXTRACCION DEL VASTAGO DE PISTON.
