Abstract

The invention relates to a device for filtering an impure fluid, comprising the following: a housing (1) with an entry channel and an exit channel (5; 6) for the impure fluid or filtered fluid, said housing having a guide device (3) for a strainer support body (4); a strainer support body (4) positioned in the guide device of the housing in such a way that it can be displaced; and a strainer (2) located in the strainer support body. The invention is characterised in that the strainer support body (4) and the guide device are arranged so that a gap is formed between them, and in that a divider (8) is provided which ensures that said gap between the guide device and the strainer support body does not close at any point during filtration, so that fluid can flow out through the gap during filtration.
