Abstract: A variable-output pump has an output-adjusting element which is acted upon by a differential piston arrangement having oppositely facing active surfaces of a smaller and of a larger active area. Control fluid is permanently admitted to the smaller active area of the differential piston arrangement to act on the same and urge the output-adjusting element of the pump toward a low-output position. A biasing spring acts against the force of the fluid acting on the smaller surface, and the control fluid is also selectively admitted to the larger surface to urge the adjusting element toward higher outputs. A control slide controls the admission of the control fluid to the larger surface of the differential piston arrangement and has a housing provided with a bore in which a slide is mounted for movement longitudinally of the bore. The slide has an end face acted upon by the control fluid and another end face acted upon by a spring. The slide has a plurality of compartments separated from one another by lands having control edges. The control fluid flows through the slide into two of the compartments, and a third compartment communicates with a relief conduit. One of the lands cooperates with a port through which the control fluid is admitted to the larger surface of the differential piston arrangement, and one of the control edges on this land has a diverging notch which circumvents this control edge when the land is juxtaposed with the port to permit a limited flow of the control fluid therethrough. The pressure of the control fluid is indicative of the performance of the pump; the fluid pumped by the pump may be used as such control fluid.

Abstract: An actuating drive for a rotor blade in a wind power installation is provided with an electric motor and a frequency converter which has a rectifier that is to be fed from a power supply system, a link connected to the rectifier, and a d.c.-to-a.c. inverter for feeding the motor, the link carrying a specified nominal operating voltage in a network-fed normal operation of the frequency converter. Furthermore, an auxiliary energy supply device is provided that is connected to the link. The auxiliary energy supply device includes and energy store which makes available a support voltage that amounts to less than 80% of the nominal operating voltage of the link. A diode is connected between the energy store and the link, and is arranged, with regard to its forward direction, in such a way that it feeds a support voltage from the energy store into the link if the link voltage falls below the support voltage. The diode prevents a current flow between the energy store and the link if the link voltage is greater than the support voltage. A charging device for the energy store has a lower charging voltage than the nominal operating voltage of the link.

Abstract: A proportional valve has an output proportional to an electrical input signal. In a preferred embodiment, the valve is actuated by a proportional solenoid having a coil which is controlled by a control signal in proportion to voltage or current. The proportional solenoid is controlled by a relatively high current such as a rectified mains voltage. A control circuit ensures that the coil of the proportional solenoid is not overloaded. Particularly, it ensures that a maximum current value is not exceeded. In this way, the mains supply required in prior art devices may be eliminated.

Abstract: A first cylinder chamber of a hydraulic cylinder is connected to a pair of variable displacement pumps of which the first one is connected to a reservoir and second one is connected to the second cylinder chamber. This allows to bias the piston by a hydraulic force acting on either side of the piston corresponding to the direction of motion. This is obtained by adjusting the delivery volume of both the pumps such that the volume supplied is larger than the volume drained. Metering the difference of both the delivery volumes results in the desired biasing counter-pressure.

Abstract: A control valve for a variable displacement pump is improved so that the levelling of the pressure fluctuations of the pump is better and quicker. For this purpose an additional control piston portion on the control piston of the control valve is used. Corresponding to the deflection of the control piston the constriction cross-section set by the control piston portion between the supply connected to the pump pressure line and a passage leading to the control space of the variable pump is varied so that the pressure rise in the control space of the pump and also the pressure drop is accelerated.

Abstract: The invention relates to a hydraulic vane type pump and to a radial piston pump. The cam ring of said pumps is adapted for horizontal and vertical movement. So as to achieve stable operating conditions for the pump at least within a certain range, a single-piece support body is mounted within the vertical adjustment screw so as to avoid a change in the level of height when the cam ring is moved axially.
