Abstract:
1. An adjusting element, comprising: a cylinder having two ends and an inner wall defining an interior space containing a pressurized medium; a piston rod axially displaceably arranged in said cylinder and connectable to a piston, said piston rod extending through one of the two ends of said cylinder; an annular seal surrounding said piston rod having an inner radially encircling circumference sealingly bearing against said piston rod and an outer radially encircling circumference sealingly bearing against the inner wall of said cylinder, said annular seal having a side facing the interior space acted upon by a pressure of said pressurized medium; and a supporting element, wherein a side of said annular seal facing away from said interior space is supported on said supporting element, an end of said supporting element facing away from said annular seal being supported on a part of said cylinder, wherein said supporting element is telescopically deformable from a normal position to an overload position to reduce an axial length of said supporting element when a bearing force of said annular seal against said supporting element exceeds a bearing force limit, a passage between said interior space of said cylinder and ambient surroundings of said cylinder being opened in said overload position, said supporting element having a first part arranged in said cylinder and a second part connected to said first part in the normal position and movable toward said first part to the overload position, said annular seal bearing on said second part, said support element having a stop with a first end supported on said first part and a second end protruding axially through said second part to a position proximate said annular seal.
