Abstract (en)
[origin: WO9412795A1] A hydraulic system with a pump (1) of fixed positive displacement, a tank (42) and a valve group connected via a tank line (118) to the tank (22) is disclosed, which has at least one load valve (105 to 107) and a control section (103) comprising a pilot overflow valve (16) for control of the hydraulic fluid supplied to the load valve in accordance with demand. In a system of that kind, it is desirable to be able to arrange an auxiliary valve arrangement in the tank line without the function of the system being adversely affected. For that purpose, besides the auxiliary valve arrangement (31) provided in the tank line (118) for controlling a further hydraulic load, provision is made for the discharge side of the pilot overflow valve (16) to be connected to a point of constant pressure.
