Abstract: A method and system for controlling fluid pressure in a hydraulically actuated device is provided, in which the device receives an input indicating the amount of work that the device is to perform, and the threshold pressure of a relief valve is adjusted so that the pressure of the fluid is appropriate for the amount of work indicated by the input. In one implementation, the device receives a user input representing the amount of work to be performed by the device. Based on the user input, a setting for a relief valve that is sufficient to maintain the fluid pressure at a level appropriate for the amount of work required is determined. An electrical signal is then sent to the relief valve to adjust it to the determined setting. Determining the proper setting for the relief valve may involve referencing a look-up table that maps user input values to electrical signal values.

Abstract: The invention proposes a novel drive with electrical power control for machines which have to execute cyclic movements with high accelerations. An electric motor drives a pump which, in turn, is connected directly to a cylinder. This arrangement has added to it a system of pressure accumulators and valves which give the system the property of an oscillator. The acceleration forces in the event of a cyclic movement near to resonance are then exerted largely by the pressure accumulators and the cylinders connected to these. This leads to a relieving of the electric motor and makes it possible to install lower powers on the machine or else, for the same power, achieve shorter cycle times of the machine.
