Abstract: According to an illustrative example of the invention a fluid damper comprises a cylinder and a piston rod axially movable through one axial end of the cylinder. The piston rod is provided with two damping pistons within a cavity inside the cylinder. The two pistons are axially spaced and in sealing engagement with an internal circumferential face of the cylinder. In a middle section of the cylinder there is provided a by-pass by an axial groove in the inner circumferential wall of the cylinder. In each axial position of the piston rod at least one piston is within the axial extent of the by-pass. When one of the pistons moves beyond the axial extent of the by-pass toward an axial cylinder end nearer to this piston, a throttled channel through this piston allows restricted fluid flow through the piston. When this piston moves in the other direction away from the nearer end of the cylinder, liquid can flow through this piston without substantial flow resistance.
