    摘要： An air intake system (30, 130) for a work vehicle (10) may include a filter assembly (32, 132) having a pre-cleaner (36, 136) and an air filter (38, 138). The filter assembly (32, 132) may define at least one outlet port (46, 146). The air intake system (30, 130) may also include an air valve (72, 172) movable between an opened position and a closed position and a blower (64, 164) coupled to the outlet port (46, 146) via a conduit (58, 158). The blower (64, 164) may be configured to create a vacuum within the conduit (58 , 158) such that particulates are removed from the filter assembly (32, 132) through the outlet port (46, 146). When the air valve (72, 172) is in the opened position, an airflow may be directed through the filter assembly (32, 132) in an intake direction from the pre-cleaner (36, 136) through the air filter (38, 138) and, when the air valve (72, 172) is in the closed position, the airflow may be directed through the air filter (38, 138) in a reverse direction.

    摘要： The invention relates to a method for cleaning a first filter and a second filter of a suction device for cleaning purposes, comprising a dirt collecting container having a suction inlet, wherein a vacuum is applied to the dirt collecting container by means of the first filter and the second filter and a first suction line and second suction line connected thereto, wherein a first closing valve and a second closing valve close a first outside air inlet and a second outside air inlet into the first suction line and the second suction line respectively, and wherein the first closing valve and the second closing valve are opened for cleaning the first filter and the second filter respectively, in order to expose the first filter and the second filter to outside air on the clean space sides thereof. According to the invention, a vacuum is applied to the dirt collecting container by means of the first suction line and the first filter, using a first suction aggregate of the suction device, and by means of the second suction line and the second filter, using a second suction aggregate of the suction device, and the first suction line and the second suction line are sealed off from each other on the clean space sides thereof at least during cleaning. The invention further relates to a suction device for performing the method.

    摘要： A method and apparatus are disclosed for unblocking a perforated rotary filter screen (14). In the invention, at least one jet of high pressure air is directed at a surface of the filter screen (14) as the filter screen (14) is rotated and the or each jet of air is moved in a direction transverse to the direction of movement of the perforations in the screen in order to cause the or each air jet to trace a spiral or helical path over the surface of the screen. The jet may be directed at the axial end face or the cylindrical wall of the filter screen.
