The inner wall of the through-orifice tightly surrounds the piston rod.

Abstract: A piston-cylinder unit with a center longitudinal axis, a first end, a cylinder filled with a fluid, a piston arranged so as to be displaceable in the cylinder and which divides the cylinder into a first work space remote of the first end and a second work space close to the first end. A piston rod is arranged at the piston and projects through the first work space and is guided out of the cylinder concentric to the center longitudinal axis at a second end opposite the first end so as to be sealed by a guiding and sealing device, and a sensor device for direct or indirect detection of the internal pressure of the piston-cylinder unit.

Abstract: A joining element for connecting a first component to a second component, wherein the joining element includes a connection member for the pivotable mounting of the first component, and part of the connection member is receivable in at least one aperture of the second component in a predetermined orientation. A fixing mechanism is provided for directly fixing the connection member to the second component when the part of the connection member received in the aperture.

Abstract: Socket housing has a hemispherical ball socket and a plurality of circumferentially spaced retaining tongues which extend toward an insertion opening, the tongues being radially pivotable to engage over the equator of a ball head. An outer part has an insertion region and a receiving opening into which the socket housing can be inserted in an insertion direction via the insertion region, the insertion region having an inside surface defining an opening with a cross-sectional area which is larger than a cross-sectional area defined by an inside surface of the receiving opening. The retaining tongues are in contact with the inside surface of the receiving opening when the socket housing is in the installed position. A locking device prevents movement of the socket housing counter to the insertion direction when the socket housing is in the installed position.

Abstract: An adjustment element includes a cylinder; a piston axially movable in the cylinder and having a piston rod; an elastic annular seal between the piston and the one end of the cylinder, the annual seal including inner and outer radially circumferences which sealingly bear against the piston rod and the cylinder, respectively; a ring-shaped supporting element which is between the one end of the cylinder and the annular seal and axially supported by the cylinder, there being at least one of a first annular gap between the supporting element and the piston rod and a second annular gap between the supporting element and the cylinder; and a safety element which fills in the at least one of the first and second annular gaps. The safety element is made of a material with low melting temperature. The annular seal is axially supported by the supporting element and the safety element.

Abstract: A piston-cylinder unit having a hollow cylinder, with a piston system supported inside the hollow cylinder that is free to move in the axial direction, and a piston rod connected to the piston system. The piston-cylinder unit is also provided with a diagnostic unit for determining diagnostic data associated with the piston-cylinder unit.

Abstract: A ball joint includes a ball head with a radially extending neck, and a socket housing having a ball socket and a fastening shaft which extends radially with respect to the ball socket. The socket has an insertion opening facing transversely of the fastening shaft, the opening having a periphery provided with a pivot notch opposite the fastening shaft, wherein the pivot notch has a width which is smaller than the diameter of the insertion opening and greater than the diameter of the pivot neck. A securing element engages the ball head and loads it into the socket, the securing element being removable away from the insertion opening to release the ball head from the socket. The neck can pivot into the notch while the ball is engaged by the securing element.

Abstract: A piston, which has a piston rod, is guided with freedom of axial movement in a cylindrical pressure tube. At one end of the pressure tube, the piston rod passes through an opening in an end wall, which closes off the end of the pressure tube. The pressure tube is surrounded by a heat-shrink sleeve, which, at the exit end of the piston rod, extends more-or-less radially inward and has a pass-through opening through which the piston rod extends. The ring-shaped end surface at the piston rod exit end of the pressure tube is enclosed by the heat-shrink sleeve.

Abstract: A cylinder has an interior space which contains a medium under pressure. A piston is displaceably arranged in the cylinder and has a piston rod which projects from the cylinder at one end of the cylinder. The piston rod is enclosed by an annular seal having an inner radially encircling circumference which bears against the piston rod and an outer radially encircling circumference which bears against the inner wall of the cylinder, a side facing the interior space to which the pressure of the medium is applied, and a side remote from the interior space supported on a supporting element. The supporting element, in turn, is supported on part of the cylinder. The supporting element includes a safety element which is designed to shorten its axial length during thermal overloading, as a result of which a passage opens from the interior space of the cylinder to the environment. The safety element is made of a melting or subliming material.
