Hydraulic System for a Transmission of a Motor Vehicle

A hydraulic system (1;

• 100;
• 200) for a transmission (2) of a motor vehicle (3), comprising:
• a pump system (5) with a first pressure outlet (6) and a second pressure outlet (7);
• a primary circuit (11);
• a secondary circuit (12);
• and
• a system pressure valve (8) with a system pressure valve slide (9),
• wherein the hydraulic system (1;
• 100;
• 200) is configured such that a secondary pump pressure (PPsek) output from the second pressure outlet (7) of the pump system (5) is fed to a radial pressure surface (26;
• 36) of the system pressure valve slide (9), and therefore an axial load based on the secondary pump pressure (PPsek) acts upon the radial pressure surface (26;
• 36) of the system pressure valve slide (9) such that the system pressure valve slide (9) is urged counter to a mechanical preload force out of a first switching position into a second switching position.
