<p>This supply circuit for a hydraulic system has at least one pressure generating device (3), at least one sequence valve (11), a main line (1) and a safety shut-off unit (93). …<??>A supply circuit is to be created which allows a hydraulic fluid to be fed in so that in all operating states any occurrence of pressure surges in the system is excluded. This is achieved in that the sequence valve (11) is designed as a slide valve, to which a plate valve (23) designed as a discharge booster is assigned, which undertakes the relevant safety functions. …<IMAGE>… </p>
