摘要： The invention relates to a portable handheld work apparatus such as a motor-driven chain saw. The apparatus includes an internal combustion engine as a drive motor for a work tool. The engine is mounted in a housing. The engine draws combustion air from the clean compartment of a filter case via an intake channel. The clean compartment is partitioned from a dirt compartment of the filter case by an air filter. The filter case itself is closed by a hood. The cover is configured as a hood of the motor housing and is pivoted about a pivot axis which is held to the motor housing by at least one bearing. In this way, the air-filter case can be cleaned in a simple manner without a tool. When the hood is flipped open, the filter case is freely accessible so that the necessary maintenance of the air filter or cleaning of the filter case is possible.

摘要： A centrifugal clutch (1) has a clutch drum (2) and at least one centrifugal weight (6). The centrifugal weight (6) is arranged on a carrier (5) and is radially displaceable referred to the rotational axis (8) of the centrifugal clutch (1). At least one holder (7, 27) holds the centrifugal weight (6) in at least one axial direction of the rotational axis (8) on the carrier (5). The holder (7, 27) includes at least one guide surface (14, 34) with which the holder is guided in radial direction to the rotational axis (8). The guide surface (14, 34) extends parallelly and radially to the rotational axis (8) of the centrifugal clutch (1). The guide surface (14, 34) is configured in a planar region of the holder (7, 27) in order to obtain a long service life of the centrifugal clutch (1).

摘要： A manually guided implement having a motor unit and a tool unit driven by the motor unit. The motor unit includes an internal combustion engine having a carburetor, and a butterfly valve. A throttle acts upon the butterfly valve via a transfer mechanism. A speed regulator is provided for the internal combustion engine. The transfer mechanism is divided into two transfer portions. The speed regulator is a mechanical speed regulator and is disposed between two transfer portions such that the throttle, via the first transfer portion associated therewith, as well as the speed regulator together act upon the second transfer portion, which is associated with the butterfly valve, whereby as its speed increases, the speed regulator effects a closing of the butterfly valve.

摘要： A walk-behind sweeper has at least one sweeping roller and an air-cooled drive motor having a drive shaft and driving in rotation the at least one sweeping roller. At least one fan wheel conveys cooling air to the drive motor wherein the at least one fan wheel is driven by the drive shaft. A dirt collecting chamber is provided into which swept-up material that is swept up by the at least one sweeping roller is conveyed. The at least one fan wheel has an intake side connected by a flow connection to a working area of the sweeper so that at least a portion of the cooling air stream for the drive motor is taken in from the working area of the sweeper.

摘要： A two-cycle engine is provided and includes a cylinder in which is formed a combustion chamber delimited by a reciprocating piston that via a connecting rod drives a crankshaft rotatably mounted in a crankcase that, in predetermined positions of the piston, communicates with the combustion chamber via transfer channels. The cylinder has an outlet from the combustion chamber. An intake duct leads into the crankcase for a supply of fuel, and an air duct supplies substantially fuel-free air. In the vicinity of the piston the air duct is divided into two branches that open out at air openings of a connecting flange formed on the cylinder. A cover is disposed on the connecting flange and extends over the air openings. A flow divider on the connecting flange projects beyond a plane thereof and into the cover. The flow divider divides an air flow in the air duct to the two branches.

摘要： The invention relates to portable handheld work apparatus including a brushcutter, edge cutter or the like. The work apparatus has a drive motor (1) and a cutting tool (2) driven by the drive motor. The work apparatus includes a guide tube (3) for guiding a drive shaft (4) as well as a handle (5) fixed on the guide tube (3). The drive shaft (4) connects the cutting tool (2) to the drive motor (1). The handle (5) is in the form of a handle bracket (8) and can be pivoted about a pivot axis (7) lying transversely to the longitudinal axis (6) of the guide tube (3) for adjusting the distance (a) of the handle to the guide tube (3). A spring action handle bracket holder (22, 23) is mounted between the handle bracket (8) and the guide tube (3). The handle bracket holder is especially vibration dampening and extends with a component in the direction of the longitudinal axis (6).
