This device comprises in combination means for passive compensation of the alternating movements of the installation, comprising at least one articulated jack connected to a source of pressurized fluid, and complementary means for fine compensation, these complementary means activating the passive compensating means in response to the variation of a parameter which characterizes the movements of the installation.

New device for applying a determined force to an element connected to an

This apparatus comprises a main jack for supporting elements from the installation and a regulating device which includes at least one pivoting jack and makes use of a source of pressurized fluid in communication with a chamber of variable volume in which the pressure of the fluid varies in inverse proportion with respect to the volume of the chamber. The main jack and the regulating device are connected in parallel to the source of pressurized fluid and the regulating device supplies a pressurized auxiliary fluid to means for adjusting the force exerted by the main jack.
