DOUBLE-ACTING LINEAR ACTUATOR

摘要

The present disclosure relates to a double-acting linear actuator for moving an inner part and an outer part of a cowl relative to a fixed frame. The linear actuator includes a first tubular body housing a first drive shaft and a second tubular body housing a second drive shaft. In particular, the first and second tubular bodies are mounted in series by the second drive shaft which is mounted on the first tubular body. The second drive shaft translates the second tubular body relative to the first tubular body when a lock of the first tubular body is in a locked position, and the first drive shaft translates both the first tubular and second tubular bodies when the lock is in an unlocked position.

主权项

1. A double-action linear actuator for moving a first element and a second element relative to a stationary element, said actuator comprising:
a first tubular body provided with means for attaching said first tubular body to the first element to be moved, a first drive shaft, housed in the first tubular body and translating the first tubular body relative to the stationary frame, a second tubular body including a means for attaching it to the second element to be moved, and a second drive shaft, housed in the second tubular body and translating the second tubular body relative to the stationary frame, wherein the first and second tubular bodies are mounted in series by means of the second drive shaft, which is mounted stationary on the first tubular body, such that the first and second drive shafts belong to a same actuating chain in which the second drive shaft translates the second tubular body relative to the first tubular body when locking means of the first tubular body are in a locked position, and wherein the first drive shaft translates both the first tubular body and the second tubular body relative to the stationary frame when the locking means are in an unlocked position.
