Abstract:
Instrument for measuring a clearance, in a given direction, between two components, comprising two rigid yokes that can slide one inside the other in the said direction and each of which comprises on the one hand, a push member capable of exerting axial thrust, in a given sense, on one--termed the first--of the said components, at least one of these members exerting its thrust by means of a spring, and on the other hand a member for resting on the other component, capable of exerting an end-stop action on this other component in the opposite sense to the sense in which the said push member of the yoke in question exerts its force, the said push members of the two yokes being capable of exerting their forces coaxially but in two opposite senses, and in that at least one of the said push members is associated with measurement means for measuring, in the said given direction, the difference between the two axial positions of the said first component, namely the end-stop position it reaches when it is urged axially by the push member of one of the yokes and the end-stop position it reaches when it is urged axially in the other sense by the push member of the other yoke, while the said other component remains trapped between the respective resting members of the two yokes.
