Abstract: The invention relates to an adjusting element having a cylinder 1, the interior space 8 of which contains a pressurized medium. A piston is arranged displaceably in the cylinder 1, said piston having a piston rod 4 which protrudes out of the cylinder 1 at one end of the cylinder 1. The piston rod 4 is surrounded by an annular seal 5 which, with its inner, radially encircling circumference, bears in a sealing manner against the piston rod 4 and, with its outer, radially encircling circumference, bears in a sealing manner against the inner wall of the cylinder 1, is acted upon, on the side facing the interior space 8, by the pressure of the medium and, with its side facing away from the interior space 8, is supported on a supporting element 10. The supporting element, in turn, with its end facing away from the annular seal 5, is supported on part of the cylinder 1, it being possible for the supporting element 10, when a defined bearing force of the annular seal 5 against the supporting element 10 is exceeded, to be deformed somewhat telescopically, reducing its axial length in the cylinder 1, from a normal position into an overload position, as a result of which a passage opening 19 from the interior space 8 of the cylinder 1 to the surroundings can be produced. The supporting element 10 has a first part 11 which is arranged in the cylinder 1 and a second part 13 which is connected to the first part, can be moved from the normal position toward the first part 11 into the overload position and against which the annular seal 5 bears, it being possible for one end of a stop to be supported on the first part 11, said stop, in the normal position, protruding through the second part 13 axially in order to extend the cylinder 1 at least until close to the annular seal 5.

Abstract translation: 本发明涉及一种具有圆筒1的调节元件，其内部空间8包含加压介质。 活塞在气缸1中可移动地布置，所述活塞具有活塞杆4，活塞杆4在气缸1的一端处突出到气缸1外。活塞杆4被环形密封件5包围，环形密封件5的内部径向 围绕圆周，以密封方式抵靠活塞杆4并且其外部径向包围的圆周以密封方式承载在气缸1的内壁上，作用在面向内部空间8的一侧上， 通过介质的压力，并且其侧面背向内部空间8被支撑在支撑元件10上。支撑元件又以其背离环形密封件5的一端被支撑在支撑元件10的一部分上 气缸1，当环形密封件5相对于支撑元件10的限定的支承力被超过时，支撑元件10可能被一些可伸缩地变形，从而将其在气缸1中的轴向长度从正常定位 导致过载位置，由此可以产生从气缸1的内部空间8到周围的通道开口19。 支撑元件10具有布置在气缸1中的第一部分11和连接到第一部分的第二部分13可以从正常位置朝向第一部分11移动到过载位置，并且环形 密封件5的支架，止动件的一端可以被支撑在第一部件11上，所述止动件在正常位置轴向地突出穿过第二部件13，以便使气缸1至少直到靠近 环形密封件5。
