| Zusammenfassung: | Proposed is a hydraulic scheme for a stepless automatic transmission of a motor vehicle. The system has a variator which is controlled by a hydraulic regulating apparatus, and which possesses a cooler (
11
) placed in an oil lubricating/cooling circulation from which a line (
14
) leads from cooler (
11
) to an oil sump (
1
). An orifice (
13
) is located after the cooler (
11
) in the line (
14
), in the direction of oil flow, the oil flow through the orifice (
13
) is controllable as a function of the speed of rotation of the drive motor of the vehicle and/or the speed of the vehicle. |
