    Abstract: A filter device has a filter element (1) received in a filter housing of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by one screw connection (32, 33). An additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). To transmit a torque between threaded elements (33) of the one screw connection (32, 33) and of the additional screw connection (41), the threaded elements are rotatable relative to each other. A coupling device (43, 46, 61) is added that allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the one screw connection (32, 33) reaches the fixed rotational state.

    Abstract: A filter device has a filter housing (1) with a filter head (3), a filter pot (7) and a removable housing cover part (51) and has a filter element (13) separating a non-filtrate side (15) from a filtrate side (17) in the housing. A bypass valve device has a valve closure element (65) preloaded by a closing spring (69) into a closed position in which it bears against a valve seat part (74). If the filter element (13) is blocked, the closure element opens up a fluid path from the non-filtrate side (15) to the filtrate side (17), by passing the filter element (13). The valve closure element (65) and the closing spring (69) are on the cover part (51). The valve seat part (74) is on an element cap (43) of the filter element (13). The element cap has a receiving part (45) forming an enclosure for that end of the filter material (27) of the filter element (13) facing toward the cover part (51).

    Abstract: The invention relates to a device for the suction filtration of fluids, such as urea solutions for exhaust gas after-treatment systems, comprising a tank (2) storing the fluid, and a filter element (34) arranged therein provided with a filter medium (32), which separates the tank contents from a clean-side inner filter cavity (20) and extends from the bottom area (10) of the tank (2) to a filling level height (28), which corresponds to a part of the filling volume of the tank (2). On the filter cavity (20), a suction connection (22) is provided, via which the cleaned fluid can he discharged by way of a suction pressure corresponding to a system operating pressure. The invention is characterized in that the filter element (34) is provided with a filler medium (32), which is air-impermeable if suction pressures are within the range of a low system operating pressure.
