摘要： The invention is directed to an arrangement of an air filter (1) and a membrane carburetor (2). The membrane carburetor (2) has an intake channel section (3) configured in the carburetor housing (4) and fuel-conducting channels (6) open into the intake channel section (3). The channels (6) are supplied from a fuel-filled control chamber (7) which is configured in the carburetor housing (4). The control chamber (7) is partitioned from a compensation chamber (11) via a control membrane (10). The compensation chamber (11) communicates with the housing (14, 16) of the air filter (1) via a compensation channel (13) downstream of an air filter element (39). The air filter housing (14) engages over the membrane carburetor (2) essentially on the side of the compensation chamber (11) and the clean chamber (24) of the air filter housing (14) communicates with the intake channel section via a connecting stub (37) which lies approximately at right angles to the intake channel section (3). The connecting stub (37) is used as a connection between the clean chamber (24) of the air filter (1) and a flow space (26) mounted forward of the intake channel section (3) in order to ensure a reliable compensation where available space is tight. The volume of the flow space (26) is greater than the volume of the connecting stub (37) and the compensation channel (13) branches away from the flow space (26).

摘要： A protective shield (2) is provided for a free-cutting tool (1). The free-cutting tool has a cutterhead (4) rotatable about a rotational axis (3) and carries a cutting filament (5). For a rotating cutterhead (4), the cutting filament (5) rotates in a rotational direction (10), aligns itself approximately radially to the rotational axis (3) and defines a cutting circle (6) having a constructively pregiven nominal radius (R). The cutting radius (6) is at least partially covered by the protective shield (2). A cut-to-length knife (7) having a cutting edge (8) for cutting the cutting filament (5) to length is mounted on the protective shield (2) in the peripheral region thereof. The cut-to-length knife (7) is mounted on the protective shield (2) to be moveable back and forth between a cutting position (11) and a rest position (12). The cutting edge (8) lies in the plane of the cutting circle (6) in the cutting position (11) and has the nominal radius (R) to the rotational axis (3) and, in the rest position (12), the cutting edge (8) lies outside of the cutting circle (6).

摘要： A two-stroke engine has a cylinder with a combustion chamber and a piston reciprocatingly supported in the cylinder. A crankshaft is rotatably supported in a crankcase and driven by the piston. At least one transfer passage connects the crankcase in at least one position of the piston with the combustion chamber and has a piston-controlled transfer port that opens into the combustion chamber and an opening that opens into the crankcase. A mixture inlet opens into the crankcase. An outlet is provided at the combustion chamber. The transfer port and the opening are displaced relative to each other in a circumferential direction of the cylinder. At least one wall section of the transfer passage forms an undercut when viewed from the crankcase in a direction of a longitudinal cylinder axis of the cylinder and is delimited by a separate component inserted into the cylinder from a side facing the crankcase.

摘要： An actuating device for a decompression valve of an internal combustion engine with a cable starter, wherein the decompression valve is positioned within the cylinder of the internal combustion engine and comprises a valve member biased into its closed position, has a transmission lever having a longitudinal extension and being rotatable about its longitudinal axis. The transmission lever has a first and a second end. A cable drum for receiving the starter cable of the cable starter is provided. The cable drum has an axis of rotation about which the cable drum is rotated when the starter cable is pulled. The longitudinal axis of the transmission lever is perpendicular to the axis of rotation of the cable drum and spaced from the rotational plane of the cable drum. The cable drum entrains the first end of the transmission lever in the direction of rotation and thereby rotates the transmission lever about its longitudinal axis such that the second end of the transmission lever performs an adjusting movement for moving the decompression valve from the closed position into the open position.

摘要： The invention is directed to a tensioning arrangement for saw chains of motor-driven chain saws which include a device for longitudinally displacing the guide bar. The clamped guide bar is released so that the adjusting arrangement can be actuated for the longitudinal displacement of the guide bar. By rotating a disc having a spiral slot, a slide piece, which is coupled to the guide bar, is displaced in the longitudinal direction. Assembly is simplified and handling facilitated when the tension in the saw chain is adjusted. This is achieved by making the slide piece on the spiral disc so that it is not released therefrom but instead is held so as to be rotationally and longitudinally displaceable. The slide piece is fixedly connected to the guide bar by using appropriate attachment devices.

摘要： The invention is directed to a tensioning arrangement for a saw chain of a motor-driven chain saw. The saw chain runs on a guide bar mounted on the motor housing of the chain saw. The tensioning arrangement includes a rotatable disc having a spirally-shaped guide slot in which a lug of a slide piece engages. The longitudinal displacement of the guide bar is provided by rotating the disc. The guide slot in the disc extends over a rotational angle of at least 270.degree.. A still lesser slope of the guide slot is provided with a rotational angle in the range of 360.degree. to 450.degree.. The tensioning arrangement is especially suitable for adjusting the guide bar in motor-driven chain saws thereby adjusting the tension in the saw chain.
