摘要： A self-propelled road milling machine is equipped with a cooling system comprising a fan for drawing in air, a cooler, and a suction channel. The suction channel has a vent opening facing the cooler and an intake opening. In relation to the longitudinal axis of the road milling machine, the intake opening points to the side of the road milling machine, so that air is drawn in from the side. This results in significantly less dirt being sucked into the machine than when the suction channel is positioned in the direction of travel. In a preferred embodiment, the suction channel is formed in one piece with a liquid tank of the road milling machine. The liquid tank and suction system therefore form a modular unit, which can be easily installed on the chassis of the road milling machine.

摘要： The invention relates to a method for cleaning the filters of a vacuum cleaner comprising a dirt collecting container, which has a suction inlet and is in flow connection with at least one suction unit via at least one filter and at least one suction extraction line, and comprising at least one external air inlet which opens into the suction extraction line downstream of the filter and can be closed by a closing valve, wherein the closing valve has a movable valve body which is acted upon by a closing spring with a closing force, which valve body lies against a valve seat in a closed position and is at a distance from the valve seat in an open position, wherein, in order to clean the filter, at least one closing valve is opened and the side of the filter that is oriented away from the dirt collecting container is impinged upon by external air. To develop the method in such a way that all the filters present can be flowed through by suction air during suction operation, but for the user there does not have to be any noticeable interruption in suction operation for filter cleaning, it is proposed according to the invention that the valve body is acted upon, irrespective of its position, by the closing force of the closing spring and, in a position at a distance from the valve seat, additionally acted upon by the repulsion force of a resilient stop element.
