Abstract
A valve, which opens upon a not permissible underpressure in a cooking utensil and upon a manual operation and which is stored in the lid of the cooking utensil suffices, without a valve spring and with a minimum of structural parts, when its flexible valve plate consists in one piece of a pressure part for manual operation and a seal collar, for abutment on a valve seat, and a connecting corpus therebetween. The seal collar is swivelled upon an overload on a swivel edge of the valve member and disengages from the abutment on the valve seat thus opening the valve.
Claims21
A valve for a cooking utensil which can be closed off with a lid, the valve comprising a valve member, said valve member having a valve seat which cooperates with a valve plate blocking until a given underpressure, wherein;
- (a) the valve plate has a seal collar, which is provided on its corpus, and extends around said corpus, is flexible and, when the valve is closed, rests on the valve seat;
- and
- (b) at least one swivel edge, which is spaced from the valve seat, and is provided within an otherwise free open flow cross section and approximately in the plane of the valve seat, the swivel edge is provided on the valve member for the seal collar, the seal collar being capable of placement against the swivel edge at a relatively small partial section of its circumference.
