<p>A piston cylinder unit is connected to a fluid container and is operated by temperature-caused volume change of the fluid. One one side, the piston-cylinder unit is fitted to a fixed holder, and on the other side it is hinged to the window. The piston (7) engages on the window (2) at a short distance from its pivot bearing (3) at a fixed hinge point (14). The devive is so pivot supported on the holder (10), that in the closed position of the window, the piston forms an obtuse angle with its region close to the pivot bearing.</p> |
