Hydraulische Lenkeinrichtung

摘要

A hydraulic steering device is disclosed, having a housing (3) in which an inner control slider and an outer control slider are arranged so that they are rotatable relative to one another and which together are arranged as alterable flow path means between a supply connection arrangement and a working connection arrangement. In such a steering device it is desirable to produce a remote control facility of simple construction. To that end, each control slider is connected to a driving slider (12, 11), and between the two driving sliders there is created at least one pressure chamber (17a-d, 18a-d) which is acted upon by fluid under pressure, and a change in volume of the pressure chamber effects a relative displacement of the two control sliders.
