Abstract
A device for transferring a fluid has a main channel, at least one secondary channel leading at an opening into the main channel, and a flexible closing element for closing the secondary channel. The opening of the secondary channel can be closed in a fluid-tight manner by the flexible closing element, by pressing the closing element with an external force onto or into the opening. In order to prevent that, in the case of a negative pressure in the main channel, the flexible closing element closes the secondary channel even without application of an external force, at least one projection is associated with the or each secondary channel and arranged in the main channel in the area of the opening of the respective secondary channel, and protrudes over the opening or over a lowest level of the opening.
