<p>1. Power-assisted device for bringing together tightly and assembling two paired elements (1, 2), of the type equipped with two locking components suitable for being inserted axially one inside the other, the female component, mounted on one of the elements, being formed by a latch (10) which is driven by elastic means (12) with a movement orientated perpendicularly to the axis of insertion in order to move aside upon the engagement of the male component (3) mounted on the other element and then to cooperate with an annular depression (3b) on said male component, at the same time as the female component is carried by a mobile part (8) which is capable of sliding, in the manner of a piston, in a hollow body (6-7), inside which said part defines two chambers (15 and 16), one (16) of which is supplied with pressurised fluid to produce the bringing together tightly of the two elements in question, while the other (15) itself receives the pressurised fluid to produce the automatic dissociation of said elements, characterised in that the latch (10) is movable within a bore (8a) made transversely in the mobile part or piston (8) and thus defines in said bore two opposed chambers respectively connected to the two chambers defined by said part in the hollow body (6-7), in such a manner that said latch is operated axially by the pressurised fluid prior to the bringing together tightly and the dissociation of the two elements (1, 2) in question.</p> |
