    • The invention relates to a pilot control for two hydraulically actuatable distribution valves (11, 12) with a hydraulic (51) or electric (75) pilot control device. To move a first distribution valve (11) from a neutral position in opposite directions, it has a handle (56) which can be moved from a neutral position in various directions. The pilot control device or two electrically adjustable pilot valves have two control outputs (78, 18) via which a pilot control pressure can be applied to a first control pressure chamber (17) in the first distribution valve (11) for adjustment in one direction and a second control pressure chamber (18) for adjustment in the other direction. Particularly to obtain a less complex and cheaper pilot control for the case where it is unnecessary or undesired for both distribution valves to be actuated at the same time, there is an electromagnetically operable changeover valve (22) which connects one control output (78) of the pilot control device (51) or an electrically adjustable pilot control valve (77) in its first switching position to a control pressure chamber (17) in the first distribution valve (11) and to one in the second valve (12) in its second position. The pilot control device is thus simplified or the number of electrically adjustable pilot control valves is reduced.

    • The invention concerns an adaptation algorithm for a controller which is monitored by a higher-level measuring loop. The control deviation xw.k is filtered through a noise filter in the measured value detection loop, the filtering factor of said noise filter being varied as a function of the control result and noise level of the measured values. The measuring loop contains a signal filter controlled by the quality of the measured values. The measuring clock sequence with which the controller will be initiated is selected as a function of the measured value quality and control result. The adaptation algorithm is provided in particular for digital controllers.

    • The invention concerns a valve arrangement (1) for supplying, in a manner adapted to the pressure and volume flow, at least one consumer which, via two working connections (A1, B1, A2, B2) of a constantly adjustable directional control valve (4, 6), can be supplied with hydraulic fluid or connected to a tank (T). Associated with the two working connections (A1, B1, A2, B2) of the valve arrangement (1) is a common pressure balance (16, 18) whose piston (66) is guided in an axially displaceable manner in an axial bore (32) in the directional control valve slide (12) such that, when the directional control valve (4, 6) is suitably triggered, one of the two working connections (A1, B1, A2, B2) can be connected alternatively to the pump connection (P). A control pressure (25), which corresponds, for example, to the highest system load pressure, the individual load pressure or a pressure derived therefrom, acts on both end faces of the directional control valve slide (12) and on the spring side of the pressure balance piston (66).

    • The invention concerns a hydraulic control circuit in which the pressure medium conveyed by a hydraulic pump of variable delivery (10) is fed, in each case via a metering aperture (17, 31), as a priority to a first hydraulic consumer (14) and only secondly to a second hydraulic consumer (15). It is already prior art to provide a priority valve (45) which comprises a first connection (46) connected to a line section (13) upstream of the metering aperture (17) of the priority hydraulic consumer (14) and a second connection (47) which is connected to the load-indicating line and whose valve member (48) can be acted upon in the opening direction of the connection between the first connection (46) and the second connection (47) by the load pressure of the priority hydraulic consumer (14) and an additional force (51). According to the invention, a priority control system is now produced without additional delivery losses and with sufficient amounts of pressure medium being conveyed in that the valve member (48) of the priority valve (45) can be acted upon in the closure direction of the connection between the first connection (46) and the second connection (47) by a pressure prevailing in a line section (13) upstream of the first metering aperture (17).

    • The invention concerns a secondary-control hydraulic drive system for lifts, wherein a hydrostatic unit driven by an electric motor feeds pressure medium into an operating pressure line (8) in which an applied pressure, if possible a constant pressure, is maintained. One or a plurality of hydrostatic lift cage driving motors (1), designed as hydrostatic units with lifting displacement, is/are connected to the operating pressure network. If these driving motors operate as pumps driven from the lift cage, flow medium is drawn out of a low-pressure line (12) and conveyed into the operating pressure network. Since sufficient flow medium for the pumping operation of the driving motors is always available owing to the preloaded pressure in the low-pressure line, the assembly can be set up in the cellar of a building in order to generate and maintain the high operating pressure whilst the driving motors can be installed at a separate location. This would be impossible if the driving motors were connected in the conventional manner to a tank pipe or a reservoir, since in that case no flow medium could be drawn out of a lower lying tank line during a pumping operation.

    • To adjust the incline of a ramp and to create a bending-resistant connection for a ramp (3) pivotably connected to a bridge support (1), a differential cylinder (10) is mounted in the area of the pivot point (2). The piston surfaces of the differential cylinder (10) are impinged upon with pressure that is adjusted in accordance with the prevailing load (11). The pressure in the cylinder chamber (10s) on the side of the rod is a measure of the bending moment in the connecting area between the ramp (3) and bridge support (1). A pressure limiting valve (13) serving as safety valve limits the bending moment. The pressure limiting valve (13) is arranged inside a line (12) directly connecting the two cylinder chambers (10s, 10b) to each other. When the pressure limiting valve (13) is actuated, hydraulic fluid is displaced from the cylinder chamber (10s) facing the rod and fed to the cylinder chamber (10b) facing the floor. To the low-pressure side of the pressure limiting valve (13) is connected a volume control container (15) which equalizes the volume between the hydraulic fluid displaced from the cylinder chamber (10s) facing the rod and the hydraulic fluid needed by the cylinder chamber (10b) facing the floor, and which, when the load on the ramp (3) is reduced, absorbs from the cylinder chamber (10b) facing the floor hydraulic fluid not required by the cylinder chamber (10s) facing the rod.
