Abstract: A fluid rotary passage is provided for sealing a fluid pressure chamber between a rotatable shaft and a shaft seat. The fluid rotary passage includes a sealing ring carrier and a fitting body, rotationally fixed or in contact with one of the shaft and the shaft seat in a fluid-tight manner and radially spaced from each other to create the chamber between them. Two sealing rings are provided axially spaced from each other and each sealingly applied with one contact surface against the carrier and one against the fitting body, for sealing the chamber against the outside. The carrier and the fitting body together form two axially spaced receiving grooves for the sealing rings, which are open toward the chamber and have at least one holding protrusion at least partially securing the sealing ring disposed in the respective receiving groove against a radial dislocation from the groove toward the chamber.

Abstract: A pressure portion (1) includes a receiver (2) for adjustable lateral support of a rack (Z) for a steering arrangement of vehicles. The pressure portion (1) arranged in positionally variable relationship guided linearly in a guide passage (F) for adjustment of the support of the rack (Z) in an adjustment direction (e), and enlarged or expanded for at least partial contact at an inside wall side in the guide passage (F) with respect to a directional component (r2) which is radial relative to the adjustment direction (e). The pressure portion (1) has radially at an outside thereof an elastomeric force application aid (11) for transmission of forces from the pressure portion (1) to an inside wall (10) of the guide passage (F).
