Abstract: A filter device for ambient air filtration has a blower housing with air inlet and air outlet. A device for generating an air flow is arranged in the blower housing and generates an air flow in operation from air inlet to air outlet. A flexible air conducting hose is provided with a first open end connected to the air outlet of the blower housing and with a second closed end. The flexible air conducting hose has openings arranged between first open end and second closed end. Filter elements are arranged in the openings, respectively. The filter elements separate a raw side inside the air conducting hose from a clean side downstream of the filter element. The air conducting hose is inflated in operation of the device by the air flow. The flexible air conducting hose has a reduced air permeability compared to the air permeability of the filter elements.

Abstract: The invention relates to an oil pan made of thermoplastic for an internal combustion engine, said oil pan comprising integrated oil cooler and an integrated oil filter, a straight connection opening being provided between the oil cooler and the oil filter.

Abstract: An oil pan of plastic material is provided with an oil suction pipe and an oil screen that is formed as one piece together with the oil suction pipe, wherein the oil suction pipe is comprised of two plastic shells and the oil screen that covers an inlet opening of the oil suction pipe is formed as one piece together with one plastic shell and extends down to the pan bottom.

Abstract: An oil pan baffle is secured by a securing device on the oil pan. The securing device has an oil pan gasket with a gasket body matched to a sealing contour of an oil pan relative to a crankcase and securing elements that are connected to the gasket body and project inwardly away from an inner perimeter of the gasket body. The securing elements act on contact surfaces of the oil pan baffle, with which contact surfaces the oil pan baffle is positioned in receptacles of the oil pan, and exert pressure effecting secure fixation of the oil pan baffle on the oil pan when the oil pan gasket is compressed by mounting the oil pan on the crankcase.
