The invention refers to a device for producing a linear movement, and to a removing device. The device includes a cylinder (1) forming a cylinder space and a piston, movable in the cylinder and dividing the cylinder space into a first space and a second space. A piston rod (5) is connected to the piston and extends out of the cylinder. A closing body (6) arranged at one end of the cylinder to form a closed space of one of the first and second spaces, wherein the closed space is intended to contain a medium. A first passage permits the medium to flow to the closed space. A second passage permits the medium to flow from the closed space. Control means controls the flow of the medium to and from the closed space via the passages. A separate element (30) includes the closure member, the control means and the passages. |
