Abstract

La presente invención esta dirigida a un sistema direccional de mando vehicular que contiene una válvula de control de centro abierto, la cual tiene una ganancia de flujo hidráulico substancialmente de cero a un ángulo de deflexión de entrada de cero, y además un área de orificio de control mínima. Un sub-ensamblado de válvula perfeccionado es utilizado en la válvula de control con funciones para recuperar rapidamente la ganancia hidráulica a angulos de deflexión de entrada relativamente pequeños. La estructura de válvula perfeccionada incluye pequeñas ranuras de escape transversales en un carrete de válvula que está en comunicación fluida tanto con las ranuras de distribución de flujo de entrada como con las de flujo de retorno, las ranuras de escape están configuradas para formar orificios de flujo parasitos que interconectan fluidicamente las ranuras de salida formadas en el manguito de válvula y el cual comunica con las cámaras de flujo formadas en los lados opuestos del pistón en el cilindro de mando. en concordancia, una vía de escape selectivamente variable es proporcionada a lo largo del cilindro de mando, los orificios de flujo parasitos tienen áreas uniformes y/o no uniformes para dar las características de realización del sub-ensamblado de válvula sean fabricadas sin dificultad.
