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.
