摘要： The invention relates to a vibration damper for belt tensioning systems comprising a piston which is rotationally mounted in a housing and which divides the housing into a first and second chamber filled with a hydraulic fluid. The first and second chambers are interconnected via a throttle point and the volume ratio of the first and second chambers changes when the piston moves in relation to the housing. The aim of the invention is to provide a vibration damper having a variable damping effect over the entire crankshaft speed range. To this end, the throttle point is configured as at least one annular gap (22), whereby an electrorheological and/or magnetorheological fluid is contained in the first and second chambers (16', 16'' ) as well as in the at least one annular gap (22), and electrically controllable capacitor surfaces and/or coil arrangements are assigned to the peripheral surfaces (14', 20) of the annular gap (22). In addition, the control is effected according to a measured variable representing the belt tension.

摘要： The invention relates to a control element that realizes controlling functions in a small space and with a low consumption of energy whereby being able to absorb high levels of stress. The inventive passive control element comprises a housing (1) that encloses a sealed, fluid-filled clean space (2). All the elements located inside the clean space are protected from soiling. The control element function is realized by means of two force elements consisting of a force introducing element (4) and of a force take-over element (21), whereby both force elements can also be joined as one. Different controlling states are distinguished by different force conveyance possibilities between the force introducing element and the force take-over element. In controlling states, the free-running state and the coupled state are differentiated in that during the coupled state, a transmission of force from the force introducing element to the force take-over element ensues. The invention is particularly advantageous in that a change in the controlling states ensues without a transmission of force, and thus without a transmission of energy, from the controlling mechanism to the force elements.

摘要： Downhole wellbore tolls (14) are actuated by electrically controllable fluids energized by a magnetic field for example. When energized, the viscosity state of the fluid may be increased by a degree depending on the fluid formulation. Reduction of the controllable fluid viscosity by terminating a magnetic field acting upon the fluid may permit in situ wellbore pressure to display a tool actuating piston (16). Displacement of the tool actuating piston (16) is prevented by the controllable fluid in a viscous state. The viscous sate of the fluid is energized by a magnetic field environment. When the field is de-energized, the controllable fluid viscosity quickly falls thereby permitting the fluid to flow through an open orifice (40) into a low pressure receiving volume (36). In an alternative embodiment of the invention, an expandable volume fluid may be used against a slip actuating element in the same manner as a fluid pressure motor. A magnetic field, aligned to act upon the controllable fluid, causes the fluid to volumetrically expand and thereby display a slip actuating piston.
