Abstract: A pressure limiting valve having a spool with raised spool lands. The spool is slidably received in a spool bore having inflow and outflow grooves that form control edges. The valve has two control edges, and a hydraulic resistance is connected in series with one of the control edges. Increasing static pressure losses at the control edges during flow, so-called flow forces, can be offset by an increasing back pressure on the valve spool, which is produced by the hydraulic resistance.

Abstract: A method for regulating or controlling the transmission ratio of an automatic power-branched transmission. Power is transmitted through a shaft driven by an engine, a variable speed drive, a gear transmission, a driven shaft, and at least two control clutches. The variable speed drive and the gear transmission are connected to each other in such a way that the regulating range of the variable speed drive is traversed in one direction within a first range of transmission ratios, and is traversed in the opposite direction within a second range of transmission ratios during traversing of the entire range of transmission ratios. The shifting strategies result in reduced wear of the endless belt device and allow for comfortable changing between the transmission ratio ranges.
