ABSTRACT:
A method and a device for flow switchover are described, the time to switch over the fluid being shortened. This is accomplished by a three-way valve, which may be provided with additional connections to the pump and the slider is designed accordingly. With the help of the connections and additional pressure storage in the slider, a corresponding pressure force is stored, which is used during the switchover process, when the connections to the fluid system and to the reservoir are closed, to superimpose over the motion of the slider, with time delay, an additional motion, which is carried out by the sliding ring positioned on the slider.
