Abstract (en)
[origin: WO8403916A1] The valve (31) functions as a flow matching device. By employing such a valve, hydraulic systems may be implemented in which filling and emptying of a variable volume load, such as a hydraulic piston (13), may be accomplished through simple check valve structures at controlled flow rates.
