A fine filter unit (2.1) and a large filter unit (2.2) are attached to a movable valve (10), which controls an inlet (11) over the large filter unit in the closed filtering space. The valve is pressed in a direction of the large filter unit by a valve spring (12), which is designed such that the inlet is opened till a preset low pressure in the closed filtering space. The inlet has a valve slot (13), which co-operates with the valve. A delivery unit (4) is arranged downstream to the device.",
