Abstract (en)

[origin: DE19539521A1] Disclosed is a two-way flow-control valve (1) by means of which the rate of flow of a hydraulic fluid can be kept constant by connecting together a restrictor orifice (32) and a control orifice. When fluid flows through the valve in the opposite direction, a non-return element (44) in the valve is moved against the bias of its own spring (48) in such a way that it opens a bypass channel which bypasses the restrictor orifice (32).
