ABSTRACT:
A check valve, especially for the medical technique having a first hose connector housing (1) and a second hose connector housing (2) and further a flexible diaphragm disk (3) positioned between the two joined hose connector housings (1, 2). At an overpressure in an entry space (6) the diaphragm disk (3) can be lifted from a lip-shaped sealing ring (13), whereby a flow cross-sectional area is created, and wherein the diaphragm disk (3) at an overpressure in an exit space (7) safely and in minimal times can be pressed onto a sealing seat to close the valve. The circular diaphragm disk (3) is produced from liquid silicone, silicone rubber or natural rubber and the thickness (3c) of the diaphragm cross-section (3a) is uniform.
