    Abstract: A device is disclosed for regulating the total output of several variable displacement pumps (1, 2) provided each with a regulating valve (18) for regulating the displaced volume. A control pressure that corresponds to the working pressure of the variable displacement pumps is applied to the regulating valves (18) against a counterpressure. The regulating valve (18) responds when the control pressure exceeds the counterpressure, regulating the variable displacement pump according to a characteristic curve (KL) of constant torque. In order to adjust the individual driving torques in a simple manner and to prevent the torques from exceeding the set values, an electronic control unit (16) is connected to the measurement sensor (25) that senses the volumes displaced by the variable displacement pumps. The electronic control unit (16) stores the sum of the set values of the counterpressures and the torque characteristic curves (KL) of the variable displacement pumps and has a set value regulator (27) that distributes the set value sum. The electronic control unit (16) further sets said torque characteristic curves (KL1, KL2), transmits control signals to the associated control element (24) that generates counterpressures corresponding to predetermined counterpressure set values, senses the working pressure (p) corresponding to the displaced volume (V) on the torque characteristic curve (KL1, KL2) when the regulating valves respond, converts said working pressure (p) into a control signal and transmits said signal to the control element that generates a counterpressure.

    Abstract: Offenbart ist ein hydraulisches Zweikreissystem zur Ansteuerung von Verbrauchern (8, 10) eines mobilen Geräts, insbesondere eines Kettengeräts, wobei die beiden Kreise mittels einer Summierventilanordnung (12) für ausgesuchte Verbraucher summierbar sind. Die Druckmittelversorgung der Verbraucher erfolgt jeweils über eine LUDV-Messblende (14) und eine LUDV-Druckwaage (16). Die Summierventilanordnung (12) ist derart ausgebildet, dass der summierte Volumenstrom aus dem summierten Kreis stromabwärts der Messblende (14) in den anderen Kreis eingespeist wird und/oder dass die Summierung erst relativ spät, d.h. phasenverschoben zum summierten Verbraucher, erfolgt.

    Abstract: The invention relates to a pipe breakage safety valve with an internal servo-valve (1) having a piston (4) which in one position on a control edge (6) blocks the connection between two internal pressure unions (2, 3) of the servo-valve. At an axial distance from said control edge, the valve piston has another control edge (8) which fluidtightly separates from the pressure unions a preloading spring (5) of the valve piston or a spring chamber (9) containing said spring.
