<p>The self-locking apparatus comprises two elements (1, 2) intended to be fixed on two structures. An intense movement of one of the elements (2) in relation to the other (1) causes the rotation of a rotatable threaded rod (14) and a rotary shift of a rotatable element (18), which causes, by means of drive surfaces (31, 35), a succession of friction elements (37) to be pressed against a substantially fixed friction surface (36) in order to lock the rotation of the said rod (14). Application to structures in thermal or nuclear power stations. <IMAGE></p> |
