HYDRAULISCHER KUPPLER MIT DRUCKBETAETIGTEM FREIGABEMECHANISMUS

摘要

A hydraulic coupler having two portions for hydraulic lines used, for example, in agricultural applications, which has an actuating device to open check valves to permit flow of fluid under pressure through said lines in response to pressure signals, for example a pressure signal in one line. The device also can be actuated to close the check valves to prevent flow through the coupler. The device is operable to permit the coupling or uncoupling of the two portions of the coupler without actuation against a high pressure.
