<p>Adjusting element comprises a cylinder (1), a piston having a piston rod (4), and a ring seal (5) surrounding the piston rod and supported on its outer side by a support element (10). The support element has a first part (11) arranged in the cylinder and a second part (13) connected to the first part and moved toward the first part out of a normal position into an overload position. The ring seal lies in contact with the second part. A stop is supported on the first part with one end which in the normal position protrudes through the second part axially to the extension of the cylinder at least in the region of the ring seal. Preferred Features: The stop is a pin-like ram (17) made especially of steel. The first and second parts in the normal position are joined together by a force-locking connection which can be removed on exceeding the specified bearing force of the ring seal.</p> |
