Abstract

The valve device (7) contains a component (17) that forms a passage (18) and is activated by the flow so that it can close the passage. The fluid pressure on the valve components upstream can exceed a specific level, whereby the flow resistance in the passage is greater than in the valve flow path upstream and downstream of the passage.
