Abstract: A filter device is provided with a filter housing and a housing cover closing off the filter housing. A filter element is disposed in the filter housing. The filter element comprises a first form-fit part projecting past an outer wall surface of the filter element. The housing cover is provided with a second form-fit part correlated with the first form-fit part. The first and second form-fit parts engage each other in a mounted state of the filter element on the housing cover. The first form-fit part is a laterally projecting hook.

Abstract: A filter device is provided with a filter housing and a housing cover closing off the filter housing. A filter element is disposed in the filter housing. The filter element has a clamping element that is resting with a clamping force on a first housing part that is provided on the filter housing or on the housing cover. The filter element further has a lever element that, in the mounted state of the filter element in the filter housing, is resting on a second housing part that is provided on the filter housing or on the housing cover and force-loads the clamping element against the first housing part. The clamping element and the lever element form a single part and are preferably provided on an end disk of the filter element.

Abstract: A filter device with filter housing and housing cover has a filter element disposed therein. A first holding part on the filter element projects past an outer wall surface of the filter element. A second holding part in the form of a counter holding part on the housing cover interacts with the first holding part. The first and second holding parts engage each other in a mounted state of the filter element. A first form-fit part is arranged on the filter element axially spaced from the first holding part and is associated with a second form-fit part in the form of a counter form-fit part. The first form-fit part and the first holding part, by rotational movement of the filter element about a longitudinal axis of the filter element, are each transferable into a form-fit engaged state with the counter holding part and the counter form-fit part, respectively.

Abstract: The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. The pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the pipe interior.

Abstract: An intake filter for an internal combustion engine for a motor vehicle including an unfiltered air intake region, a filter medium and a filtered air conduit, in which the unfiltered air intake region is arranged beneath the engine hood of the motor vehicle and is attached to the engine hood. The filter medium is tubular body which has a porosity that ensures a sufficient filtration of the intake air for the internal combustion engine.

Abstract: A filter system for an internal combustion engine of a motor vehicle has a housing with a top housing part and a bottom housing part. A filter element is arranged inside the housing. An unfiltered air connector is connected to the housing. A clean air connector is connected to the housing The top housing part has a support grate embedded in foam material. The support grate and the foam material are configured such that bending of the top housing part in a direction of the bottom housing part is ensured when a load is applied.

Abstract: An intake system for an internal combustion engine to avoid water intake, which includes a main air inlet (10), an auxiliary air inlet (11), and an air filter (12). In the main air inlet (10) there is a valve 16 to sealingly close the main air inlet (10) and a moisture sensor (15), which is connected so as to communicate with an evaluator (22) which, in turn, is connected to at least one other sensor (23) disposed outside the intake system and provided to detect other functions. Examples of possible other sensors (23) include rain sensors and/or temperature sensors. The sensor signals are coupled and or correlated in the evaluator (22), and in accordance with a logic which resides in the evaluator (22), a control signal is produced that opens or closes the main air inlet (10) by means of the valve (16), which can be moved into the respective open or closed positions by any of a number of diverse types of drives, such as, electrical, pneumatic, or electro-pneumatic drives.
