Title (EN) HYDRAULIC MECHANICAL DIVERTER
(FR) DÉFLECTEUR MÉCANIQUE HYDRAULIQUE
Abstract:
(EN) Hydraulic diverter is disclosed that makes it possible to use a single hydraulic control line to operate a flow control device. The hydraulic diverter diverts fluid from the hydraulic control line alternately first to one fluid compartment, then to the other fluid compartment of an actuator. In some implementations, the hydraulic diverter employs a piston that rotates circumferentially as it is driven axially to provide the alternating connection to the actuator fluid compartments. The piston has a flow path through it that deviates away from the piston's central axis so fluid exits at or near one side of the piston instead of the center. As the piston rotates, the deviated flow path becomes aligned with, and thus connects hydraulic fluid to, one fluid compartment of the actuator. As the piston continues to rotate, the deviated flow path becomes aligned with, and thus connects hydraulic fluid to, the other fluid compartment.
(FR) L'invention concerne un déflecteur hydraulique qui permet d'utiliser une seule conduite de commande hydraulique pour actionner un dispositif de commande d'écoulement. Le déflecteur hydraulique dévie alternativement le fluide de la conduite de commande hydraulique, d'abord vers un compartiment de fluide, puis vers l'autre compartiment de fluide d'un actionneur. Dans certains modes de réalisation, le déflecteur hydraulique utilise un piston qui tourne de manière circonférentielle lorsqu'il est entraîné axialement pour procurer la liaison alternative aux compartiments de fluide d'actionneur. Le piston a une voie d'écoulement le traversant, qui s'écarte de l'axe central du piston, si bien que le fluide sort au niveau ou à proximité d'un côté du piston au lieu du centre. Lorsque le piston tourne, la voie d'écoulement déviée s'aligne avec le compartiment de fluide de l'actionneur et relie ainsi le fluide hydraulique au compartiment. Lorsque le piston continue de tourner, la voie d'écoulement déviée s'aligne avec l'autre compartiment de fluide et relie ainsi le fluide hydraulique à l'autre compartiment.
