Abstract:
1. A filter device with at least one filter element ( 11 ) comprising a filter medium ( 27 ) disposed between two receiving parts ( 31 , 35 ) and a connecting means located at the lower receiving part ( 35 ) for a fluid connection to a fluid apparatus, in particular to a fluid tank ( 1 ), with a closing part ( 45 ) which is disposed on the connecting means and which is pretensioned by the action of a first energy storage mechanism ( 43 ) for a movement proceeding away from the upper receiving part ( 31 ) into a closed position which blocks the connecting means, with a further second energy storage mechanism ( 49 ) for producing a relative motion between the lower receiving part ( 35 ) and a closure part ( 17 ) of the device and with a sealing means ( 55 ) which acts to seal between the lower receiving part ( 35 ) and the closure part ( 17 ) as soon as the latter and the lower receiving part ( 35 ) are in contact with one another under the influence of the second energy storage mechanism ( 49 ).
