Abstract
The flow path switching valve described herein has a valve chamber with three openings and a valve piston disposed in the valve chamber. The valve piston has a flexible diaphragm which at its circumference co-operates sealingly with an inner circumferential wall of the valve chamber. The valve piston is movable between two end positions; in a first end position, it opens a flow path between a first opening and a second opening and blocks a third opening, and in the second end position, it blocks the first opening and opens a flow path between the second opening and the third opening. The wall of the valve chamber is shaped such that in the last phase of the diaphragm movement to the first end position, the sealing contact between the diaphragm and the inner wall is undone in at least part of the circumference.
