Abstract
In one example, an apparatus for filtering a fluid (e.g., a plastic melt having impurities) includes a housing which has at least one inlet for introduction of the fluid and an outlet for delivery of the fluid and a cavity formed in the housing by wall portions of the housing for receiving a sieve support, and a sieve support which is arranged moveably in the cavity of the housing and has a longitudinal axis for receiving at least one filter element for filtering the fluid. The sieve support externally has a plurality of integrally formed raised portions and/or raised portions and/or recesses are formed at wall portions of the housing, that delimit the cavity, such that provided between the wall portion and the sieve support are a plurality of gaps/cavities, by means of which a slight fluid flow is enabled in operation. Another example concerns a valve arrangement.
