Abstract: The invention relates to a piston-cylinder unit having a pressure pipe (1), in which an axially slidable piston is arranged, which piston is sealed at a first end of the pressure pipe (1) and is guided outwardly, which piston has a sleeve (7) at the second end of the pressure pipe (1) that is located opposite the first end of the pressure pipe (1), which sleeve (7) can be displaced telescopically to the pressure pipe (1) and encloses the pressure pipe (1) with part of the length of the sleeve (1), and the end of which sleeve (1) facing away from the pressure pipe (1) is closed and bears a connecting piece (8). Coaxially from the second end of the pressure pipe (1), a threaded part having an external thread and being rigidly connected to the pressure pipe (1) extends, in the outer thread of which threaded part an inner thread arranged on the inner wall of the sleeve (7) engages. In the cylindrical inner opening (10) of the sleeve (7) a non-detachable threaded nut (9) is inserted at axial spaces both to the end facing the pressure pipe (1) and to the end of the inner opening (10) of the sleeve facing the connecting piece (8). At the end of the threaded part facing away from the pressure pipe (1), the threaded part has a radial expansion, which in a position of the sleeve (7) that coaxially is the farthest away from the pressure pipe (1), is in abutment with the end face of the threaded nut (9) facing away from the pressure pipe (1).

Abstract: The invention relates to a temperature-driven valve assembly (6), comprising: a channel portion (13) for fluidically connecting two chambers (4, 5) for receiving a fluid, the channel portion having a through-opening (16) for the fluid; and at least one switching element (8) having an opening configuration in an opening temperature range and a closing configuration in a closing temperature range. The switching element (8) is at least partly movable relative to the channel portion (13) along a movement axis (A) in a temperature-driven manner. An opening normal of the through-opening (16) is directed toward the switching element (8). The channel portion (13) is surrounded by a channel wall (9) extending peripherally around the movement axis (A). The valve assembly (6) comprises at least one sealing element (10) extending peripherally around the channel wall (9). The sealing element (10), when in an installation position, lies against at least one sealing surface (9A) of the channel wall (9). A surface normal of the sealing surface (9A) is directed at the switching element (8). The at least one sealing element (10), when in the installation position, sealingly cooperates with the at least one sealing surface (9A) and the at least one switching element (8) in the closing configuration and closes the through-opening (16). The at least one sealing element (10), when in the installation position, is spaced apart from the at least one switching element (8) in the opening configuration along the movement axis (A) such that a primary fluid path (11) fluidically connects the two chambers (4, 5) through the through-opening (16) and between the at least one switching element (8) and the at least one sealing element (10). The valve assembly (6) comprises at least one recess (14) in the channel wall (9). A projection of the at least one recess (14) along the movement axis (A) is completely surrounded by a projection of the sealing surface (9A) along the movement axis (A). In an operating position of the sealing element (10), in which the sealing element (10) is spaced apart from the at least one sealing surface (9A) along the movement axis (A), a secondary fluid path (15) fluidically interconnects the two chambers (4, 5) through the at least one recess (14).

Abstract: In a piston-cylinder assembly comprising a cylinder in which a piston rod is installed with freedom of axial movement and which is filled with a blocking medium, a braking device becomes active when the piston-cylinder assembly moves faster than a defined speed and thus limits the speed to a desired extent. A valve body divides the cylinder into two working spaces, which are connected to each other by at least one flow-through opening. As soon as the defined speed is exceeded, the dynamic pressure in the working space elastically deforms a disk, which has the effect of at least partially sealing off the flow-through opening(s) in opposition to the forces trying to keep them open. The elastic deformation of the disk represents a closing movement relative to the cross section of the flow-through opening(s). The disk takes the form of a valve ring, which is installed in a valve ring groove with a certain freedom of axial movement. The valve ring moves toward one or the other side wall of the groove depending on the direction of movement and thus at least partially seals off the minimum of one flow-through opening as a result of the dynamic pressure-induced deformation of the valve ring.

Abstract: The invention relates to a bonnet which can pivot on rear mounted hinges. A latch (3) on the bonnet engages with a lock (1) which can slide vertically in guides (2). A sensor system is provided which senses the approach of an obstruction, e.g. a pedestrian. The sensor system releases the lock by releasing a retaining latch (10) electrically so that he bonnet lifts slightly, say 40 mm. On impact the bonnet/latch assembly moves downwards against a spring dampening the force of impact.

Abstract: The unit (1) has a blocking medium in a cylinder (3). A brake unit limits an adjustment speed to a desired value. A valve body divides the cylinder into two working chambers (9,11) connected by at least one flow opening (13). The flow openings are at least partly closed or opened according to the dynamic pressure in the working chamber by an axial valve ring (15). The flow openings are at least partly closed or opened according to the dynamic pressure in the working chamber by an axial valve ring (15) at a given adjustment speed against an opening force, in which the pressure in the working chamber deforms the valve ring elastically. The deformation forms a closure part with respect to the cross-section of the flow opening. The valve ring moves against a groove side wall. The valve ring deformation at least partly closes the flow opening, which has a stepped profile with pockets in the area of the groove side wall. The valve ring guides a closure path in the pocket by deforming.

Abstract: A pneumatic strut for use as an opening power assist mechanism for a motor vehicle tailgate has a piston rod extending from a piston contained within a cylinder. The piston separates the cylinder into two work chambers, each containing a gas charge under pressure. A bypass opening is active to connect the work chambers during the initial opening displacement of the tailgate to automatically open the tailgate through a first opening angle range. A second valve can be externally actuated to connect the two work chambers to further selectively open the tailgate into a second opening angle range. To close the tailgate, a third, directionally dependent valve can automatically connect the two work chambers during the closing displacement of the tailgate.

Abstract: According to an illustrative example of the invention, a gas spring (11) is combined with a telescopic tube (12) which is axially slidable on the cylinder (9) of the gas spring. The piston rod and the telescopic tube are provided at the respective most remote ends thereof with fastening eyes (15). The telescopic tube (12) can be fixed in a plurality of positions with respect to the cylinder (9). For such fixation, the cylinder is connected with a carrier within the telescopic tube between opposite end walls of the cylinder and the telescopic tube. A locking bolt (18) is guided within the carrier in a direction transverse to the axis of the telescopic tube. This locking bolt is engageable with a corresponding plurality of openings (19) of the telescopic tube. The locking bolt is biased by spring means (20) into an engagement position with respect to a respective opening (19) and can be released from such engagement by being inwardly pressed by an operator.

Abstract: A column unit, in particular a column unit for chairs, comprising a base tube (310) and a gas spring (318) additionally contains an axially movable guide bush (314) which is inserted so as to be axially movable in the upper end (310b) of the basic tube (310) and, in turn, surrounds a part (318b) of the gas spring (318) so as to be axially movable. An extension movement of the guide bush (314) in conjunction with extension of the gas spring (318) can be guaranteed inter alia by carrying stop means (326, 314g). Limiting this extension movement takes place by extension-limiting stop means (316, 312g), the latter being designed to be releasable for demounting the column unit.
