Abstract

A system and method serve for optimizing the efficiency of an oil supply having at least two different oil pressure levels. The system has at least two feed devices and at least one control slide with at least two narrowed sections. Each of the narrowed sections is assigned one of the feed devices. Depending on the position of the narrowed sections in the control slide, the respective volume flows are automatically divided into the at least two pressure levels for each of the feed devices as a function of the oil requirement in the respective pressure level.
