Control valve for power steering

摘要

The valve has a valve slide (14) movably accommodated in a guide (15) along an axis (16) for acting upon a side by a hydraulic liquid and on an opposite side with defined supporting forces. An opening structure (23) is provided at one of the slide and the guide. A movement of the slide relative to the guide effects a change of a free passage area of the structure that is uncovered by a cover, where the liquid flows from an inlet (9) through the area to an outlet (11). The structure has a defined shape such that the area is linearly independent on the movement of the slide.
