摘要
The invention relates to hydraulic control in a hydraulic system for the operation of a machine tool such as a press for processing material of a certain type, especially for the operation of the scrap cutters. Said control allows for impact attenuation and combined rapid motion switching with load compensation and transfer of a hydraulic medium of a hydraulic cylinder for the movement of the other. According to the invention, said control comprises hydraulic media of a hydraulic cylinder for pre-control of a first main valve element ( 2.4.0 ), a second main valve element ( 2.7.0 ) and a third main valve element ( 3.7.0 ) which are functionally combined and a fourth valve ( 2.5 ).
