    摘要： The invention is directed to a cutting arrangement for a motor-driven chain saw and is configured as a preassembled component which includes a guide bar having a saw chain and sprocket drive wheel. A tensioning device is integrated into the guide bar for holding the parts of the component together. The tensioning device holds the sprocket drive wheel at a spacing from the end face of the guide bar. The tensioning device is adjustable when placing the component on the housing of the chain saw in such a manner that the sprocket drive wheel is released while the saw chain remains under tension. The component can be disassembled into its individual parts by adjusting the tensioning device.

    摘要： A connecting piece (1) is disposed between a carburetor (4) and an inlet channel (3) in an internal combustion engine of a portable handheld motor-driven work apparatus. The connecting piece functions to compensate for relative position changes between the engine and the carburetor (4), is made of elastic material and includes an expansion fold (5) for compensating for changes in position. The length of the expansion fold (5) is changeable from a collapsed to an expanded length. The expansion fold (5) subdivides the connecting piece (1) into a carburetor-end channel section (6) having a circularly-shaped cross section and an engine-end channel section (7) having a cross section departing from the circular form at the end facing toward the engine. The connecting piece (1) has a constant flow cross section over its entire length when the expansion fold (5) is collapsed.

    摘要： A hand-held working tool has a housing and an internal combustion engine arranged in the housing and comprising a crankshaft and an air filter. A tool is driven by the crankshaft of the internal combustion engine. A fan housing is attached to the engine housing and has an air inlet. A fan wheel is arranged in the fan housing and is driven by the crankshaft of the internal combustion engine to supply cooling air, sucked in through the air inlet, to the internal combustion engine. The fan housing has a bottom extending radially to the crankshaft. The bottom and a side of the fan wheel facing the bottom define a chamber in the fan housing. The bottom has a combustion air outlet. A combustion air channel is connected to the combustion air outlet and to the air filter. The combustion air outlet is axially supplying combustion air from the chamber through the combustion air channel into the air filter of internal combustion engine. The fan housing has a channel wall having a bottom portion connected to the face of the bottom remote from the fan wheel and covering the bottom partially to form a double-walled bottom. The end face portion of the combustion air channel is defined by the bottom and the bottom portion of the channel wall. In an alternative embodiment the combustion air channel is provided in a hollow beam of a support that supports the drive unit of the working tool.

    摘要： The invention is directed to a handle for a pull-rope starter. The handle includes a T-shaped base body having an elongated part extending in the direction of the pull rope and a handle part extending transversely to the elongated part. The elongated part has a receptacle for accommodating an elastic expansion element which is connected at one end thereof to the pull rope. The expansion element is supported at its other end on the base body. The expansion element is as long as possible and has the longest possible expansion path. This is achieved in that the expansion element is supported at its upper end on the base body with the upper end facing away from the pull rope. In this way, the expansion element is stretched thereby providing a longer expansion path.
