Abstract: A belt scraper having a scraper element to be brought into abutment with a belt. The scraper element is pivotably arranged with reference to a pivoting axis. A spring element generates a torque acting on the scraper element. A sensor for determining a pivoting angle of the scraper element is a contactless sensor with an index part and a detecting part for detecting the position of the index part. The index part is arranged, at a distance from the pivoting axis, on a movable element that is coupled to the scraper element.

Abstract: A vibration damper having a sensitive response behavior at very low amplitudes comprises a separating piston being disposed inside a bypass so as to move axially freely. The separating piston divides the bypass into two chambers mutually sealed from one another. Two valves are disposed in the bypass. The first valve acts in a compression stage as a pressure limiting valve and as a non return valve in an extension stage. The second valve acts as a pressure limiting valve in the extension stage and as a non return valve in the compression stage.

Abstract: A hydraulic vibration damper has a cylinder that is filled with a damping medium, displaceably accommodates a working piston disposed on a piston rod, through which the damping medium can flow, and is divided by the piston into two chambers. There is an equalization chamber that is connected with the working chamber, a pressure channel connected with the chamber on the piston rod side, and a controllable setting valve module connected with the pressure channel and the equalization chamber. The setting valve module has a pilot valve arrangement having a pilot pressure chamber and a pilot valve. The pilot pressure chamber is hydraulically separated from the main valve, and is connected with a valve chamber by a connection channel and at least one throttle point. A pressure element counteracts opening of the main valve, and pressure that acts on the main valve can be varied by the pilot valve.

Abstract: A dashpot featuring amplitude-dependent shock absorption, especially intended for the wheel of a vehicle and including a hydraulically parallel cylindrical pressure-compensation chamber (8). The pressure-compensation chamber is partitioned by an axially displaceable floating piston (10). At least one face (25) of the floating piston is provided with a resilient bumper (18). The object is a dashpot with a floating piston that arrives more gently at its limit inside the pressure-compensation chamber (8). The bumper is accordingly accommodated in an axial hollow (17) that extends through the body (15) of the floating piston.

Abstract: The invention relates to a vibration damper having an amplitude-selective damping device, comprising a damper tube (1) which is filled with damping fluid and in which a piston rod (2) is disposed in such a manner as to be able to move in a reciprocating manner, said piston rod supporting a damping piston (5) which divides the inner space of the damper tube (1) into a piston rod-side working chamber (3) and a working chamber (4) remote from the piston rod, a space (6) to receive damping fluid, which space is disposed inside a bypass provided between the working chambers (3, 4) and hydraulically in parallel with the damping piston (5) and in which an axially moveable separating piston (7) is disposed which divides the space (6) into a piston rod-side chamber (8) and a chamber (9) remote from the piston rod, wherein the bypass comprises at least a first hydraulic connection channel (10), via which the piston rod-side working chamber (3) is connected to the piston rod-side chamber (8), and at least a second

Abstract: Screw locking arrangement for a screw connection comprising a threaded spigot, a nut, a first locking washer and at least one second locking washer, wherein the first locking washer is connected in a non-rotational manner to the nut, wherein the first locking washer has first profiling on a first surface and the second locking washer has second profiling on a second surface, and wherein the profiling of the first locking washer is engaged with that of the second locking washer in such a way that a relative rotation of the two locking washers with respect to each other can be effected in only one rotational direction which leads to an increase in the tensioning force of the screw connection, wherein between the second locking washer and the threaded spigot a positive rotational locking arrangement is provided.
