Valve arrangement for regulating the flow behavior of a magnetorheological fluid

摘要

Valve arrangement for regulating a magnetorheological fluid flow with a valve housing (6), in which at least one electric coil arrangement (7) for generating a variable magnetic field is provided, whose magnetic flux lines in an area within the valve housing (6) are oriented essentially parallel to one another, as well as with a valve inlet - (1, 22) and valve discharge opening (2, 23) which, by means of a fluid-tight flow channel (20, 21) are connected, by means of which the magnetorheological fluid flow can be directed and the at least one flow channel section (4) from said magnetic flux lines largely vertically oriented parallel to each other is,the flow channel section (4) in a fluid-tight manner by means of at least on one side by a flow channel element (11) is limited, the modularly in the valve housing (6) may be implemented to,characterized in thatin the valve housing (6) and / or within the of the valve housing (6) of the writing end of adjustable volume permanent magnets (10) are provided and the in the region of the flow channel (20, 21) by the permanent magnetic field of the current through the coil arrangement (7) is compensated for variable magnetic field caused.
