Abstract
A hydraulic system for a vehicle including a distributor, or switch, valve for actuating at least two operational areas and supplying the two areas with sufficient amounts of hydraulic medium is provided. The distributor, or switch, valve preferably comprises a flow regulator valve and a solenoid valve, which function so that the supply of hydraulic medium to the steering system always has priority, ensuring that the vehicle is steerable in any situation. When the steering system is operational, the supply of hydraulic medium to other operational areas, such as the clutch and transmission systems, is completely blocked by operation of the switch valve. If, however, the clutch and transmission systems should require hydraulic medium during operation of the steering system, the switch valve allows a small portion of hydraulic medium to be supplied to the clutch and transmission as well.
