Abstract
(EN)
A failsafe module comprising an input member (310), an output member (312), and a coupling mechanism for coupling the input member to the output member. The coupling mechanism comprises an intermediate member (316a) movable relative to the output member to energise an energy storage device and a latch mechanism (318, 320) to hold the energy storage device in an energised state. When the latch mechanism is engaged, the input and output members are coupled together and the energy storage device is held in an energised state and isolated from the coupling between the input and output members. When the latch mechanism is released, the energy storage device can release its energy to drive the output member to a predetermined position.
(FR)
Cette invention concerne un module à sécurité intégrée, comprenant un élément d'entrée (310), un élément de sortie (312), et un mécanisme de couplage pour coupler l'élément d'entrée à l'élément de sortie. Le mécanisme de couplage comprend un élément intermédiaire (316a) mobile par rapport à l'élément de sortie pour exciter un dispositif de stockage d'énergie et un mécanisme de verrouillage (318, 320) pour maintenir le dispositif de stockage d'énergie dans un état excité. Lorsque le mécanisme de verrouillage est en prise, les éléments d'entrée et de sortie sont couplés l'un à l'autre et le dispositif de stockage d'énergie est maintenu dans un état excité et isolé du couplage entre les éléments d'entrée et de sortie. Lorsque le mécanisme de verrouillage est libéré, le dispositif de stockage d'énergie peut libérer son énergie pour entraîner l'élément de sortie vers une position prédéfinie.
