  • Patent number: 11890651
    Abstract: A venting device with a splash guard for deflection of splashing water entering the interior of the venting device has slats with a front section arranged at the exterior. Venting slots are formed between the front sections. At least one of the slats has a deflection section arranged at the interior and a central section connecting deflection section and front section. The front section and the deflection section are angled relative to the central section. The front section of the at least one slat in the operating position of the venting device extends from the central section toward the top side. The deflection section extends in the operating position from the central section toward the bottom side. The deflection section has a region oriented at an angle of less than 90° relative to the central section. A power tool with such a venting device is provided.

  • Patent number: 9464606
    Abstract: A handheld work apparatus has at least one tool which is driven by a combustion engine. A portion of an intake channel of the combustion engine is formed by an elastic connecting piece which has a first section and a second section between which an expansion fold is arranged. The expansion fold has a first side wall and a second side wall arranged downstream of the first side wall. A peripheral wall, which extends in the region of the largest outside diameter (a) of the expansion fold, is arranged in flow direction between the first side wall and the second side wall. The connecting piece has a stop for the expansion fold which prevents a segment of the first side wall adjoining the peripheral wall from bearing against the second side wall.

  • Publication number: 20150026988
    Abstract: A hand-held work implement comprises a housing, at least one tool and a combustion engine for driving the tool. The combustion engine has a cylinder and has a piston which drives a crankshaft in rotation about an axis of rotation. The crankshaft drives a fan impeller. The work implement has a handle unit with a handle bar and has an engine unit, these being connected to one another via anti-vibration elements. The combustion engine has a transverse plane which encompasses the cylinder longitudinal axis and which runs parallel to the axis of rotation of the crankshaft. The transverse plane divides the work implement into a front region, in which a section of the tool that projects out of the housing is arranged, and a rear region. The fixing of the anti-vibration element to the cylinder is realized in the front region.

  • Publication number: 20150027745
    Abstract: A handheld work apparatus has a motor unit comprising a drive motor. The drive motor drives a tool of the work apparatus, for example a saw chain. The apparatus has a grip unit with a handle that is vibrationally decoupled from the motor unit via an antivibration element. The antivibration element is connected to a first component of the grip unit via a holding device and a second component of the motor unit via a holding element. Arranged in the connection of the first component to the second component through the antivibration element is a predetermined breaking point formed in a third component that is replaceable independently of the first component and the second component. The strength of the connection of the first component to the second component through the antivibration element is lowest at this predetermined breaking point.

  • Patent number: 7909009
    Abstract: An internal combustion engine has a cylinder which has a cylinder longitudinal axis. The internal combustion engine has at least one cooling fin. In order to route the cable in a defined fashion so that the internal combustion engine can be arranged even in a constricted installation space, a cable retainer is provided which is arranged on at least one cooling fin of the internal combustion engine and which retains at least one cable. A cable retainer for securing at least one cable to an internal combustion engine has at least one receptacle for at least one cable and at least one means for positioning the cable retainer on the internal combustion engine.
