Servo valve

摘要

The present invention concerns a servo valve, in particular for hydraulic power steering systems of motor vehicles, in the form of a rotary slide valve having a rotary slider and a control bushing which coaxially encloses the latter and is rotatable about a rotation axis, against spring force, relative to the rotary slider. The present invention includes a particular spring arrangement which has two helical compression springs lying in a radial plane of the rotation axis.
