    摘要： A hydraulic system for actuating a clutch of a vehicle, in particular a commercial vehicle, having a pressure reducing valve under system pressure for pressuring the clutch with an actuating pressure in normal operation, where at least one additional reserve valve assembly is provided for emergency operation. In addition, a hydraulic system is proposed for actuating a variator of a CVT transmission of a vehicle, in particular a commercial vehicle, having at least one pressure reducing valve for pressuring a first shifting chamber and a second shifting chamber of the pulleys with an adjusting pressure to set a transmission ratio in normal operation, where at least one selector valve is connected to the first shifting chamber and the second shifting chamber of the respective pulleys.

    摘要： 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.
