Abstract

An aerating and venting valve having a small opening for venting, characterised in that the ventilation opening (20) on its end section facing the closing body (30) is constructed in the form of a cylinder with a relatively small diameter, and a needle (22), whose diameter is approximately equal to the diameter of the said cylindrical ventilation opening, is arranged such that it can move relative to the latter so that, when the ventilation valve moves into the closed position, it penetrates into this ventilation opening and at the same time cleans said opening. <IMAGE>
