Abstract: The invention relates to a filter (10) for a suction device, in particular a vacuum cleaner, a wet vacuum cleaner or the like, to a suction device, and to a cleaning method, the filter comprising a filter housing (11) within which a suction air duct (12) for conveying a suction air flow is formed, the filter housing having a centrifugal separator (13) for separating particles from the suction air flow and a container (14) for collecting the separated particles. The filter has a metering device (15) disposed upstream of the centrifugal separator in a flow direction of the suction air flow, the metering device being configured to spray liquid into the suction air flow.

Abstract: An intake manifold section for installing in an intake system of an internal combustion engine may have a tube body including an inlet opening, an outlet opening and a fresh air path section running from the inlet opening to the outlet opening. An air mass sensor may be fastened to the tube body and protrude into the fresh air path section. A bypass channel may be disposed on the tube body and bypass the fresh air path section connected to a blow-by gas path at an inlet side.
