Abstract
The invention relates to a filter device having a filter housing part (10) which comprises a filter element (12) and which can be detachably connected to the other filter housing part (20). Because there is a valve means (24) which clears a fluid path in the interconnected state of the housing parts (10, 20) and in the separated state of the housing parts (10, 20) from one another at least partially blocks it, instead of known quarter-turn fastener and stopper solutions a blocking means is devised which can be economically implemented and which requires decidedly less installation space. The invention relates also to a process for operation of a filter device.
