摘要： A carburetor having a carburetor body in which an intake channel portion is formed. At least one fuel opening opens out into the intake channel portion. Pivotably mounted in the intake channel portion is a butterfly valve that in a completely opened position divides the intake channel, in the region of the butterfly valve, into a mixture channel and a feed channel, so that in the completely opened position of the butterfly valve, flowing into the feed channel is combustion air having a fuel content that is less than the fuel content in the mixture channel. Provided in the intake channel portion is at least one partition section that extends between the feed channel and the mixture channel. The partition section is formed on the carburetor body.

摘要： A chain saw includes a guide bar for a saw chain, a housing, a sprocket wheel cover, and a stud fixed on the housing for threadably fastening the sprocket wheel cover and the guide bar. The free thread end of the stud has a maximum usable screw-in depth (tmax) for a nut. A stop for the sprocket wheel cover having a stop surface as well as a support surface for contact engaging the stop surface are provided. In the mounted state of the guide bar, a distance (a) remains between the stop surface and the support surface. The support surface contact engages the stop surface when the guide bar is removed and the nut is tightened and screwed onto the studs to a stop screw-in depth. The stop is configured in such a manner that the maximum usable screw-in depth (tmax) is greater than the stop screw-in depth.

摘要： A protective cover for a cutting wheel of a hand-held cut-off machine driven by an internal combustion engine has a circumferential wall and two opposed sidewalls adjoining the circumferential wall. The circumferential wall and the two sidewalls are a monolithic component made of cast light metal. The circumferential wall in a circumferential direction has at least over sections thereof a first integral thicker portion. The two sidewalls are thinner than the first integral thicker portion. Preferably, the protective cover is made of diecast magnesium.

摘要： A work apparatus has at least one handle (12) and a drive motor (3). The handle (12) is connected to said drive motor (3) via at least one anti-vibration element (16, 17, 18, 19, 20). The anti-vibration element (18, 19) is held on a first housing part and coacts with a second housing part. To achieve good damping, the anti-vibration element (19) includes a damping section (25) having an annularly-shaped wall (37) which expands in the direction of the second housing part.

摘要： The invention is directed to an adjusting device for a throttle pull of an internal combustion engine for a portable handheld work apparatus. A pull wire (11) of the throttle pull acts on the carburetor (4) of the engine. The carburetor (4) is attached to the inlet of the engine with a spacer (6) disposed therebetween. A tension piece (5) of the adjusting device is pivotally journalled on the spacer (6) by a bolt. The pull wire (11) lies with a segment thereof on the outwardly pivotable arm of the tension piece (5). The position of the tension piece can be adjusted with the adjusting screw (14). The adjusting screw can be screwed out of the pivot arm axially in the direction toward a support. The tension piece (5) is configured as one piece with the bolt (12) and is securely held with a form-tight holding arrangement in the axial direction of the bolt (12). The adjusting device is cost-effective and provides for a reliable and precise adjustment.

摘要： A handheld work apparatus includes a drive motor (28) to drive a tool and at least one handle (3) as well as at least one anti-vibration element (9) that includes a coil spring (10). The coil spring (10) is operatively connected to the handle (3) at one end and with the drive motor (28) at the other end. The anti-vibration element has a tear-off guard (29) which extends through the anti-vibration element (9). A centering element (21) is arranged on the tear-off guard (29) to avoid, in a simple manner, that the tear-off guard moves radially outwards.
