摘要： A hand-held power tool transmission closure having a base body for closing a transmission housing opening of a transmission housing of a hand-held power tool, in particular a hammer drill or a combi-hammer, wherein the hand-held power tool transmission closure includes a tube protruding from the base body, which extends in the transmission housing when the base body closes the transmission housing opening. The hand-held power tool transmission closure includes an air channel which extends in a first air channel section through the base body and in a second air channel section through the tube so that an air mass can flow through the air channel into and out of the transmission housing.

摘要： A filter device for a vacuum cleaner, including a turbine device, for generating at least one first and one second main air flow through at least a portion of the vacuum cleaner, and a control unit. The filter device includes a first chamber including a first filter element, a first outflow opening, a first inlet opening and a first pressure surge element, which divides the first chamber into a first and a second space and is reversibly movable between a first and a second position, the first main air flow being able to flow into the first space of the first chamber through the first filter element and to flow back out through the first outflow opening, a second chamber including a second filter element, a second outflow opening, a second inlet opening and a second pressure surge element, which divides the second chamber into a first and a second space and is reversibly movable between a first and a second position, the second main air flow being able to flow into the first space of the second chamber through the second filter element and to flow back out through the second outflow opening. The first pressure surge element and the second pressure surge element alternately are reversibly movable to alternately clean the first and second filters.

摘要： A side handle for a hand-operated power tool includes a handle rod disposed along a handle axis and a fastening mechanism, where the side handle is releasably fastenable to the hand-operated power tool by the fastening mechanism. The fastening mechanism includes a tensioning band that engages around a fastening axis and a tensioning mechanism. The tensioning mechanism has a pull rod that is anchored to the tensioning band and is displaceable along the handle axis and a tensioning wheel that is rotatable about the handle axis and engages in an external thread of the pull rod. A damper connects the handle rod to the fastening mechanism and includes a leaf spring with a longitudinal side oriented in an inclined manner to the fastening axis where the leaf spring has a slot. A splint is fastened to the pull rod and engages in the slot.

摘要： A hand-held power tool includes a tool holder for holding a tool on a working axis, a pneumatic striking mechanism for striking the tool, and an absorber, which includes a bending spring, situated transversely to the working axis, and a mass body. A countershaft is driven by the motor around a rotation axis which runs in parallel to the working axis. A wobble drive for driving the pneumatic striking mechanism is situated on the countershaft. In addition, a cam disk is situated on the countershaft and includes a cam which projects in a start-up direction which runs in parallel to the working axis. The bending spring includes a counterpiece provided relative to the cam. The cam, which abuts the counterpiece, pretensions the bending spring in the start-up direction.
