A fluid actuating drive for relative translational movement of first and second structural parts has a housing filled with a pressurizing medium, which in its longitudinal direction, runs along a gap that separates the structural parts, and is connected therewith. The width of the gap is dependant upon the relative position of opposing side walls of the housing, which side walls can be moved against one another with a pressurizing agent for the relative movement of the structure, where the side walls are alternately connected to the first and second structural part across the gap.

1. A fluid actuated drive for relative movement of first and second structural parts across a gap separating said parts, said drive having a first housing with a pressurizing agent therein, said first housing running along a longitudinal direction of the gap; wherein:a width of the gap depends upon relative positions of side walls of the first housing which face each other, and which are movable toward and away from each other by adjusting pressure of the pressurizing agent for movement of the structural parts; an inner part of the first housing contains a flexible hose; and each of the side walls of the first housing is connected with a respective one of said structural parts which is on an opposite side of the gap, intermittently along the longitudinal direction of the gap.
