Unidirectional valve for a respiratory product

A one-way valve for a respiratory product is to be improved in respect of a low resistance to through-flow. To achieve this object, there are provided two membrane-like valve discs (12, 13) which butt against one another at a central dividing line (16), which are fixed in place at a point on the val...

Zusammenfassung:	A one-way valve for a respiratory product is to be improved in respect of a low resistance to through-flow. To achieve this object, there are provided two membrane-like valve discs (12, 13) which butt against one another at a central dividing line (16), which are fixed in place at a point on the valve body (11) and which are able to move after the fashion of flaps as a result of the flow of breathing gas. Serving as a valve seat is a central cross-member (19) on the valve body (11) which extends along the dividing line (16), and supporting cross-members (21) arranged on either side thereof.
