    Abstract: A ventilation unit for a suction device, wherein the ventilation unit is designed to let an air flow into an interior of the suction device, wherein the ventilation unit has a first sliding element and a second sliding element which are connected by a connecting element, wherein the first sliding element, the second sliding element and the connecting element form an active unit which is able to be brought from a closed position into an open position, and vice versa, by an actuator. A method for ventilating a suction device with a ventilation unit, wherein first of all a suction device having a ventilation unit is provided, the active unit of which is in a closed position. By actuation of the actuator, the active unit is brought into an open position such that the interior of the ventilation unit and/or of the suction device can be ventilated by an air flow which can pass into the interior of the ventilation unit and/or of the suction device through a first opening, exposed by a first sliding element, of the ventilation unit. In further aspects, the invention relates to the use of an air flow, which can be conducted into the interior of a suction device in particular to dedust a filter of the suction device using at least one ventilation unit.

    Abstract: A filter cassette for a vacuum cleaner appliance positionable in the vacuum cleaner appliance in an airflow drawn in by the vacuum cleaner appliance, wherein the filter cassette contains substantially a lateral surface, an upper opening, and a lower opening, such that the drawn-in airflow, in order to filter out dirt particles, can flow into the filter cassette through the lower opening and out of the filter cassette through the upper opening. A first sealing element extends in a first plane and the a second sealing element extends in a second plane, and wherein the first and second planes are arranged at an acute angle to one another, such that the second sealing element is oriented substantially horizontally when the filter cassette is positioned in a filter cassette receptacle accessible from outside the vacuum cleaner appliance. A vacuum cleaner appliance having a filter cassette receptacle for receiving a filter cassette. The filter cassette receptacle extends substantially in a center plane that is positioned at an acute angle to a parting plane.

    Abstract: The side handle for a hand-operated power tool (5) has a handle rod (2) which is arranged along a handle axis (7) and intended for holding the side handle (1) by one hand, a fastening mechanism (3) and a damper (6). The fastening mechanism (3) for releasably fastening the side handle (1) to the hand-operated power tool (5) has a tensioning band (10), which engages around a fastening axis (12), and a tensioning mechanism (11). The tensioning mechanism (11) has a collar (16) which overlaps with the tensioning band (10) along the handle axis (7) and is displaceable with respect to the tensioning band (10) along the handle axis (7), a pull rod (19) which is anchored to the tensioning band (10) and is displaceable along the handle axis (7), and a tensioning wheel (18) which can be rotated about the handle axis (7) and engages in an external thread (36) of the pull rod (19). The damper (6) connects the handle rod (2) to the fastening mechanism (3). The damper (6) has at least one longitudinal side (26), which is oriented at an inclination to the fastening axis (12), of a leaf spring (23), wherein the leaf spring (23) has a slot (30) which extends along the handle axis (7). A splint (31) is fastened to the pull rod (19) and engages in the slot (30) in the leaf spring (23).

    Abstract: A invention relates to a filter device for a vacuum cleaner having a turbine device and a motor for generating a first main air stream and/or a second main air stream through a collecting tank of the vacuum cleaner, wherein the vacuum cleaner includes two chambers and filter elements of the filter device are dedusted by an abrupt change in position of a pressure shock element in the chambers. Since, when one of the two chambers is being dedusted, the suction operation of the vacuum cleaner can be maintained through the other chamber, the filter dedusting can advantageously take place during continued suction operation of the vacuum cleaner. A method for dedusting a filter device in a vacuum cleaner, wherein, as a result of a valve being actuated, an air volume is driven out of one of the two chambers. As a result of this change in pressure, the pressure shock element is advantageously made to change position, and this can result in a backflushing pulse and mechanical shaking of the filter element, and dedusting of the filter device.
