Device i.e. milk frother, for use in fully automatic coffee machine to emulsify mixture of air, steam and milk, has pressure compensating element provided in region of low-pressure chamber and comprising membrane

摘要

The device (1) has a steam supply channel (3) flowing into a low-pressure chamber (2), and a milk supply channel (4) flowing into the low-pressure chamber so that the milk is sucked-in by low pressure. A pressure compensating element (12) is provided in a region of the low-pressure chamber. The pressure compensating element has a membrane (13) that separates the low-pressure chamber from an environment. The compensating element is directly or indirectly connected to the low-pressure chamber by a pressure compensating channel (14).
