Abstract

Perfeccionamientos introducidos en una válvula de control de flujo que tiene un orificio dispuesto en la parte central de un paso de flujo que comunica la lumbrera de entrega de una bomba de fluido hidráulico con un dispositivo hidráulico y una válvula de carrete que es accionada en respuesta a la diferencia de presiones hidráulicas para devolver una cantidad de fluido hidráulico en respuesta al grado de actuación del mismo desde dicho paso de flujo a la lumbrera de aspiración de dicha bomba, caracterizados porque dicho paso de flujo incluye un paso de flujo que permite que el fluido hidráulico pase por el orificio en el que está montada de manera deslizable la válvula de carrete, y dicha válvula de carrete está provista de una parte de pequeño diámetro que cubre la abertura de una parte de pequeño diámetro que cubre la abertura de dicho paso de flujo conectada en dicho orificio con una holgura predeterminada cuando dicha válvula de carrete es accionada, y la diferencia de presiones hidráulicas entre el lado de aguas arriba y el lado de aguas abajo de dicho orificio y un orificio variable constituido por dicha abertura y dicha parte de pequeño diámetro, es hecha actuar sobre dicha válvula de carrete.
