Abstract

Mejoras introducidas en un sistema automático de retención de fluido aplicable en sistemas hidráulicos que incluye una bomba de fluido (10) y dos válvulas de fluido (12,13) así como dos motores hidráulicos (14,16) estando todos estos elementos conectados conjuntamente para permitir la circulación del fluido y dispuestos para conducir el fluido a través de dichas válvulas y hacia y a partir de dichos motores, teniendo cada una de dichas válvulas y cada uno de dichos motores dos conexiones de fluido (21, 22, 23 y 24) para la entrada y la salida del fluido hacia y a partir de dichas válvulas y dichos motores, y teniendo dichos motores dos capacidades diferentes de circulación de fluido proporcionadas la una respecto a la otra con relación a dichas dos conexiones de fluido, estando dichas mejoras caracterizadas porque dichas válvulas tienen cada una dos orificios de fluido (31, 32) conectadas para permitir la circulación del fluido con dichas dos conexiones de fluido respectivas de dichas válvulas, y teniendo dichos orificios tamaños de circulación de fluido proporcionados a dichas capacidades de dichos motores, teniendo cada una de dichas válvulas un orificio de fluido suplementario (28, 29) conectado con dicha bomba para permitir la circulación del fluido, y teniendo dichas válvulas cada una un elemento de cierre de válvula móvil (33) que actúa con dichos orificios para abrir y cerrarlos de acuerdo con las fuerzas hidráulicas aplicadas a dichos elementos de cierre, de tal manera que dichos elementos de cierre se sitúen en las posiciones de cierre cuando la circulación de fluido en una de dichas conexiones de fluido está desproporcionada con relación a la circulación de fluido en la otra de dichas conexiones.
