Abstract
The invention relates to a filtering device () comprising: a filter support element () which is movably mounted in the housing (), which has the shape of a cylindrical bolt, and which has multiple filter chambers (), a filtering element being arranged in each said filter chamber; and an inlet channel () and an outlet channel () in the housing (), wherein the inlet channel and the outlet channel are each to be connected to at least one filter chamber in a production position. The aim of the invention is to increase the effective filtering surface. This is achieved in that at least two pairs of filter chambers are provided on the filter support element. The filter chambers of each pair are arranged on the filter support element in a diametrically opposed manner, and there are no connections between the filter chambers within the filter support element. At least one respective intermediate channel () that extends in the direction of the longitudinal axis () of the filter support element () is provided between the outlet channels in the housing and the filter chambers. Intermediate channels of different lengths are provided for each pair of filter chambers.
