Title
(EN) SELF CONTAINED HYDRAULIC LOCK APPARATUS
(FR) APPAREIL DE VERROUILLAGE HYDRAULIQUE AUTONOME
Abstract
(EN)
A hydraulic lock apparatus includes a hydraulic actuator, a pressure storage device connected to the hydraulic actuator, and a control valve configured to actuate to a first position and a second position. The control valve fluidly isolates the pressure storage device from the hydraulic actuator when the control valve is in the first position. The control valve fluidly connects the pressure storage device to the hydraulic actuator when the control valve is in the second position.
(FR)
Un appareil de verrouillage hydraulique comprend un actionneur hydraulique, un dispositif de stockage de pression relié à l'actionneur hydraulique, et une soupape de commande conçue pour agir sur une première position et une seconde position. La soupape de commande isole fluidiquement le dispositif de stockage de pression de l'actionneur hydraulique lorsque la soupape de commande est dans la première position. La soupape de commande relie de manière fluidique le dispositif de stockage de pression à l'actionneur hydraulique lorsque la soupape de commande est dans la seconde position.
