| 摘要 |
The present invention relates to a percolation device (1) that comprises a percolation chamber, as well as a base (2) in which the following are provided: an axial discharge outlet (8); a sleeve (3) that is axially movable and which has an axial ejection outlet (16); an axially movable compression surface (18) which, with a packing head (10) axially defining the discharge outlet (8), axially defines the percolation chamber; and a lever (5) for driving, in a differentiated manner, the sleeve (3) and the compression surface (18) such that, when the sleeve (3) is in a position in which it releases from the discharge outlet (8), the grounds, driven out of the sleeve (3) by means of the ejection outlet (16) through the compression surface (18), are in line with the discharge outlet (8).
