FILTERING DEVICE FOR FLUIDS

摘要

The invention relates to a filtering device (100) comprising: a filter support element (10) which is movably mounted in the housing (30), which has the shape of a cylindrical bolt, and which has multiple filter chambers (11.1, 11.2; 12.1, 12.2), a filtering element being arranged in each said filter chamber; and an inlet channel (31.1, 31.2 32.1, 32.2) and an outlet channel (41.1, 41.2; 42.1, 42.2) in the housing (30), 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 (13.1, 13.2, 14.1, 14.2) that extends in the direction of the longitudinal axis (19) of the filter support element (10) 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.

1. A filtering device for filtering fluids, said filtering device having a housing and a cylindrical bolt-shaped filter support element:
said cylindrical bolt-shaped filter support element mounted movably in said housing and having multiple filter chambers, each of said filter chambers having a filter element, said housing having a plurality of inlet channels and a plurality of outlet channels configured such that each of said filter chambers moves into connection with a respective inlet channel and a respective outlet channel when said filter support element is moved to a certain production position, such that when said filter support element is in the production position a respective inlet channel in said housing leads to a respective filter chamber and each of said outlet channels in said housing leads away from a respective filter chamber, and wherein, said filter support element has at least two pairs of said filter chambers, each said pair comprising two filter chambers arranged diametrically opposed on said filter support element such that within said filter support element there are no connections between said filter chambers, said filter support element has a plurality of intermediate channels each configured to be positioned between a respective outlet channel in said housing and a respective filter chamber in said filter support element, said filter support element having a longitudinal axis, each of said intermediate channels extending in a longitudinal direction, each said pair comprising two filter chambers having two respective intermediate channels of different longitudinal length, such that:
when said filter support element is in said production position, each filter chamber of one of said pairs is connected with at least one of said inlet channels and with at least one of said outlet channels, andsaid filter support element is moveable to a maintenance position in said housing, and when said filter support element is in the maintenance position one or the other filter chamber of one of said pairs is connected reciprocally with at least one of said outlet channels.
