Abstract
Apparatus for applying a substantially constant tension to an elongated member connected to an installation subjected to alternating movements which comprises the combination of at least one jack supporting said elongated member with regulating means located on the installation, supplying a determined working pressure with the use, as pressure source, of an accumulator delivering to a jack an auxiliary fluid under a pressure varying with the displacement of one element (piston or cylinder) of said jack, comprising at least two jacks, one of which has one element articulated to a fixed point and the other element articulated to one element of another jack through a movable articulation member compelled to be displaced along a predetermined path when one of the elements of a jack is displaced with respect to the other.
