    • The invention relates to a control device for supplying a pressure means to preferably, several hydraulic consumers. Said control device has a load-sensing-regulated variable displacement pump (10) whose setting can be varied according to the highest load pressure of the hydraulic consumers being activated, by means of an LS pump regulating valve (27); proportionally adjustable directional-control valves (38), which are situated between a supply line (12) extending from the displacement pump, a discharge line (63) leading to a tank (11), and the hydraulic consumers; and a load indicator line (26), through which the LS pump regulating valve can be subjected to the highest load pressure of the hydraulic consumers being activated at the same time. A control device of this type sometimes lacks the desired dynamics. The aim of the invention is therefor to further develop the known hydraulic control device in such a way that the displacement pump can continue to operate in an energy-saving manner with the usual LS behavior but if desired, can also operate with greater dynamics. To this end, arbitrarily switchable valve elements (60, 61) are provided. Said valve elements can be switched into a mode in which a pressure can be built up in the load indicating line from the supply line, by means of said valve elements.

    • The invention relates to a regulating device for an adjustable hydraulic pump (1). Said device has a delivery flow control valve (15) and an output control valve (27). The delivery flow control valve (15) is subjected to the pressure difference between a first control line (18b) which is connected to the delivery line (5b) downstream of a metering throttle (6b), and a second control line (19) which is connected to the delivery line (5b) upstream of the metering throttle (6b). The delivery flow control valve (15) then regulates the adjusting pressure for an adjusting device (7) according to this pressure difference in order to adjust the delivery volume of the hydraulic pump (1). The output control valve (27) is situated between the first control line (18b) and a pressure medium tank (4). The control pressure in the first control line (18b) acts upon the output control valve (27) in the direction of opening and the adjusting device (7) acts upon the output control valve (27) by means of a spring measurement device (29) in the direction of closing. According to the invention, several consumers, each connected to the hydraulic pump (1) by a separate delivery line (5a-d) in which an adjustable metering throttle is located, can be controlled by the regulating device. A first control line (18a-18d) is connected to the delivery line leading to the designated consumer upstream of the designated metering throttle (6a-6d). A first pressure change device (17, 40, 41) selects the highest of the control pressures in the first lines (18a-18d) and conveys this to the delivery flow control valve (15). The output control valve (27) is only connected to the first control lines (18b, 18d) of the selected, output-controlled consumers, the first control lines (18a, 18c) of the remaining, non output-controlled consumers being separated from the output control valve (27).

    • The invention concerns a power- and moment-regulating system for at least two adjustable hydraulic pumps (10, 11), said system comprising for each hydraulic pump (10, 11) a hydraulic servo control apparatus (22, 23) for continuously adjusting the delivery. To that end, the delivery of each hydraulic pump (10, 11) is determined as a function of the delivery pressure of the respective hydraulic pump (10, 11) in a delivery pressure line (16, 17) associated with the hydraulic pump (10, 11) and the control pressures in control lines (20, 21) provided for each hydraulic pump (10, 11). Each servo control apparatus (22, 23) is provided with a moment valve (42, 43) having a valve piston (62) which can move in a valve sleeve (61) and forms a valve seat with the latter and whose closure force is determined by a measuring spring arrangement (46, 47) which is connected to the pump actuator (37, 38) and is pretensioned as a function of the set delivery. To that end, each moment valve (42; 43) connects the control line (20, 21) of the associated hydraulic pump (10; 11) to an outlet (41) as a function of the control pressure in this control line (20; 21) and the control pressure in the control line (21; 20), that is the control pressures in the control lines of the other hydraulic pump(s) (11; 10) in each case, under the pretension of the measuring spring arrangement (46; 47). According to the claimed development, for a given hydraulic pump (10; 11), the control pressure in the control line (21; 20) or the control pressures in the control lines of the other hydraulic pump(s) (11; 10) in each case act both on the valve piston (62) and on the valve sleeve (61) of the moment valve (42; 43) associated with the given hydraulic pump (10; 11).
