摘要

The device for the feed of a fluid has a feed chamber (2) which has at least one flow inlet opening, an outlet opening, and a feed element (4). The feed element has a feed surface with free movement end (4a) in the direction of the feed by which an oscillating back and forth movement is executed. The free movement end of the feed element executes travel perpendicular to the direction of feed, especially through which the feed surface is driven to operate around an axis (5).
