Abstract
A filter device includes at least one filtering element arrangeable in a filter housing () connectable to a hydraulic device (), in particular a hydraulic tank. The tank is connectable to the filter housing through hydraulic connections () by a connection system in such a way that a fluid is enabled to circulate. The filter housing is removably mounted on the hydraulic device () by a fixing unit. The fixing unit is embodied in the form of a bayonet fitting () which is lockable and detachable by the filter housing () rotation. The connection system has at least one movable locking element which locks in the locking position the hydraulic connection () associated with it, and releases the connection after displacement in the open position. The locking element is displaceable in a sealing or opening position by rotational motions of the housing () for detaching and locking the bayonet fitting ().
