摘要

Device with energy accumulation for automatically manoeuvring mechanical assemblies such as hatches or sluices. Means for locking using antagonistic levers 24 come to rotationally block a flange 16 securely fastened to the drive shaft of a spring motor 15. Safety of the locking is ensured by an electromagnet 36 interacting with the crankshaft 22 on which the antagonistic levers 24 are articulated. <IMAGE>
