Abstract
Switching valve with a valve body, which separates two working spaces filled with a fluid. The valve body has pass-through openings which are covered except for an inlet cross-section, where the inlet cross-section is controlled by a switching disk as a function of the direction of flow in the switching valve. Between the switching disk and the inlet cross-section, at least one spacer disk is provided, which has at least one opening, which communicates with the inlet cross-section, where the opening has a larger two-dimensional area than the inlet cross-section.
Claims6
A switching valve comprising
- a valve body for separating two working spaces filled with a fluid from each other, said valve body comprising pass-through openings,
- means for covering said pass-through openings, said means having therein at least one inlet opening having a cross-section over at least one pass-through opening,
- a switching disk for controlling the cross-section of the inlet opening as a function of the direction of flow of fluid through the pass-through openings, said switching disk being located over said means for covering said pass-through openings, and
- a spacer disk located between the switching disk and the cross-section of the inlet opening, said spacer disk having therein at least one opening which communicates with the cross-section of the inlet opening, said opening in said spacer disk having a surface area which is larger than the cross-section of the inlet opening.
