A fluid cylinder comprising a cylinder wall and a piston slidably engaged with an inner surface of the cylinder wall, the piston having a packing fluid-tightly engaged with the inner surface of the cylinder wall, the packing being in contact with the inner surface of the cylinder wall. A fluid characterized in that it consists of a main packing part that is always in close contact with the cylinder wall and an auxiliary packing part that is displaced by a shape memory alloy ring so that it is in close contact with the cylinder wall at low temperatures but separates from the cylinder wall at high temperatures. Cylinder.
