Abstract

Hydraulically depth compensated actuator (0) comprising a hollow rod actuator (10), consisting of a first cylinder (11), a first ring piston (12), a hollow rod (13), connection means (14) at each axial end of the hollow rod actuator (10) and a second cylinder (15), mounted concentric with the first cylinder (11) and fastened to the upper end of the cylinder (11), the ring piston (12) is adapted to slide on the outer diameter of the second cylinder (15), a first volume (VI) is formed by the outer diameter of the hollow rod (13), the Iower end of the first cylinder (11), the inner diameter of the first cylinder (11) and the ring piston (12), and may be filled with oil or gas, a second volume (V2) is formed by the outer diameter of the second cylinder (15), the upper end of the first cylinder (11), the inner diameter of the first cylinder (11) and the ring piston (12), and may be filled with oil, gas or be under vacuum, a third volume (V3) is formed by the inner diameter of the second cylinder (15), the upper end of the first cylinder (11), the inner diameter of the hollow rod (13) and the lower end of the hollow rod (13), and may be filled with oil, gas or be under vacuum, a Depth compensation means is connected to either the second volume (V2) or the third volume (V3) via conduit means.Hydraulically depth compensated actuator (0) comprising a hollow rod actuator (10), consisting of a first cylinder (11), a first ring piston (12), a hollow rod (13), connection means (14) at each axial end of the hollow rod actuator (10) and a second cylinder (15), mounted concentric with the first cylinder (11) and fastened to the upper end of the cylinder (11), the ring piston (12) is adapted to slide on the outer diameter of the second cylinder (15), a first volume (VI) is formed by the outer diameter of the hollow rod (13), the lower end of the first cylinder (11), the inner diameter of the first cylinder (11) and the ring piston (12), and may be filled with oil or gas, a second volume (V2) is formed by the outer diameter of the second cylinder (15), the upper end of the first cylinder (11), the inner diameter of the first cylinder (11) and the ring piston (12), and may be filled with oil, gas or be under vacuum, a third volume (V3) is formed by the inner diameter of the second cyl inner (15), the upper end of the first cylinder (11), the inner diameter of the hollow rod (13) and the lower end of the hollow rod (13), and may be filled with oil, gas or be under vacuum , a Depth compensation means is connected to either the second volume (V2) or the third volume (V3) via conduit means.
