Abstract (en)

[origin: EP2444360A2] The system has a load-pressure signaling branch (20a) utilized as a load-pressure signaling path. The signaling path stays in connection with a load-pressure signaling line (21) provided for controlling conveying volume of a pump and guiding high load pressure to a selected load (4) i.e. hydrocylinder. The load is provided with a pressure cut (50) for load pressure protection. The pressure cut of the load is attached to a load side (A) of the load. A pressure balance (11a) is attached to the load side and actuated along direction of a locking position for the pressure cut of the load side.
