Abstract

Perfeccionamientos en dispositivos de control de fluido, en particular para gatos de doble efecto, caracterizados porque cada dispositivo comprende un primer nivel limitador de presión, un segundo nivel que constituye una chapatela de retención y de frenada de un flujo de fluido y medios dispuestos entre estos dos niveles para realizar el pilotaje de la chapaleta de retención y de frenada, a partir de la presión establecida por el limitador, disponiéndose estos dos niveles y los medios de pilotaje coaxialmente en un alojamiento que atraviesa el cuerpo de parte a parte.
