aparelho para servir um líquido em um copo, em particular de vinho, contido em um recipiente

摘要

The invention relates to an apparatus (1) for pouring into a glass (2) in order to reduce the risks of spoiling the wine (3) poured by said apparatus. Vacuum tapping means (10) are sealingly connected to the upper portion (4A) of the vessel (4) and maintain a pressure therein which is between a first predetermined value P1 lower than the atmospheric pressure and a predetermined value P2 lower than P1, and liquid tapping means (20) are sealingly connected to the lower portion (4B) of the vessel and pump liquid from said lower portion up to an area for pouring into a glass. The vacuum tapping means includes a vacuum source (11) for lowering the pressure in the upper portion (4A) of the vessel (4) to P1 and vacuum partial-compensation means (14) adapted for feeding a gaseous fluid into the upper portion of the vessel when the pressure in said upper portion is lower than P2.
