Abstract (en)
[origin: EP2218675A2] The system has a pump (1) i.e. fixed displacement pump, and a working hydraulics system (2) operated by an electrohydraulically operated control valve (11) i.e. directional control valve. An electrically operated pilot valve is provided for controlling the control valve and connected with a control pressure supply line (25). A pressure regulating valve (26) is connected with a supply line (4) of the pump and provided for generating a control pressure that is supplied to the control pressure supply line, and a locking valve (28) is arranged upstream of the pressure regulating valve.
