Abstract
A non-return valve, in particular for medical purposes, including a first hose connection housing, a second hose connection housing and a membrane disk which is made from flexible material. The membrane disk is arranged between the two hose connection housings and can be raised up from an annular valve seat in communication with an inlet space which is connected to an inlet passage. A medium-permeable formation which faces the membrane disk is arranged on the inlet side into the inlet space, supporting the membrane disk against overextension in the case of high return pressures.
