| 摘要 |
The invention relates to a method for regulating the inlet feed pressure ps in a hydraulic system. The method comprises a feed pump 23 for generating feed pressure ps, at least two hydraulic operating elements 8a, 8b, 8c, measuring elements for measuring the pressure levels of the operating elements 8a, 8b, 8c and a flow duct system for hydraulic pressure medium. The method seeks to analyse which of the operating elements 8a, 8b, 8c has a load pressure generated by the transfer of the load (positive work). The greatest pressure level of the operating elements 8a, 8b, 8c performing load- transferring work is selected and the inlet feed pressure ps is adjusted on the basis of the pressure level selected. <IMAGE>
