Abstract

A reverse suction unit (10) controlled by a very small low pressure is positioned in the supply conduit (4) near the lowest point of the container (1), between the container floor and the base of the filter insert (7). A non-return valve (20) between the reverse suction unit and the interior space (9) of the filter insert, opens towards the interior space. The reverse suction unit consists of a ring-shaped plate valve, with valve pan (11) surrounding the supply conduit. The valve pan is covered by a first ring-shaped valve plate (12) with bores (13). A second similar valve plate (14) with compression spring (15) closes the bores.
