Abstract: This invention relates to a valve with a valve housing which has several valve components. Sealing surfaces are provided on the circumference of the valve housing which correspond with a valve accommodating body carrying the valve housing. These surfaces are adapted to engage the valve accommodating body where (in dependence on the relative motion of the valve housing in respect of the valve accommodating body) the material volume existing on the circumference of the and plastically displace it into a circumferential recess of the valve housing.

Abstract: The invention relates to a sensor for the measurement of movement, with a preferably rotarily movable transmission unit (rotor) for indicating movement and with a stationary device (stator) for the generation of an electric signal for sensing the movement of the transmission unit. The measuring device includes a measuring element which is fixed within a measuring element chamber defined by a two-part housing. A carrier housing fixes the measuring device relative to the transmission unit and accommodates electric connections from the measuring device and surrounds the two-part housing at least in part.

Abstract: A solenoid-operated pressure control valve in which a valve shaft can move transverse to its longitudinal axis to permit self-centering of a closure member at the end of the valve shaft, relative to a valve seat which receives the closure member, when the valve shaft is displaced along its longitudinal axis. Longitudinal displacement of the valve shaft is sealedly guided by at least one sealing element through which the valve shaft extends and which can move along a surface of a guide member against which the sealing element is positioned when the valve shaft undergoes self-centering which is permitted by the clearance fit between the valve shaft and a bore in the guide member through which the valve shaft extends.
