摘要： A manually guided suction device or blower is provided that has a housing in which is formed a spiral blower path in which is disposed an impeller that is rotatably driven by a drive motor. The spiral blower path has an air-conveying air inlet and an air-withdrawing outlet. A connector is provided for the detachable connection of an air-conveying connection conduit, whereby when the connection conduit is mounted it overlaps with the connector, which is secured to the housing, over a prescribed axial length. To achieve a mechanically secure connection, an annular sealing element is held in a groove in a surface of the connector or connection conduit in the overlap region, wherein over the entire circumference thereof, the sealing element projects beyond such surface.

摘要： A manually guided implement having a drive motor is provided. For a translatory movement of a tool member, the rotational movement of the drive motor must be converted by a gear arrangement, which has a gear wheel that is coupled with a component that glides on the end face of the gear wheel. To significantly reduce frictional losses and also wear of the pertaining components, a constantly effective, reliable lubricant is required. For this reason, at least one cutout is provided in the main body of the gear wheel and/or in the component that can glide on the end face thereof. Such cutouts are open to a glide plane and serve to accommodate a lubricant.

摘要： A hedge clipper is provided that has an internal combustion engine that is to be started by hand. By means of a clutch and a gear mechanism, the engine drives cutting blades in a reciprocating manner; the cutting blades are guided and held in a cutter bar. Disposed on the output side of the clutch is a brake drum around which extends a brake band. The first end of the brake band is fixed to the housing, and the second end of the brake band is held on a pivotable brake lever that is acted upon by a brake spring that urges the brake band into engagement against the brake drum. The brake lever can be moved into an inoperative position of the band brake by a release lever against the force of the brake spring. The release lever cooperates with an adjusting cam that is disposed directly adjacent to the brake lever and in the inoperative position of the band brake forms a rest stop for the brake lever, receiving the force of the brake spring.

摘要： The invention relates to a two-stroke engine for a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine, brushcutter or the like. A crankcase (4) is formed below the engine cylinder (2). A piston (5) moves up and down in the cylinder (2) and drives a crankshaft (7) rotatably journalled in the crankcase (4). A fuel-containing mixture is supplied via a membrane carburetor (8) to the combustion chamber (3) delimited between the piston (5) and the cylinder (2). A bypass channel (22) is provided parallel thereto and supplies essentially fuel-free air to the combustion chamber (3). The bypass channel (22) opens into a channel segment (21) via a connecting piece (24) fixedly attached to the cylinder (2). The channel segment (21) is formed in the cylinder wall (16). A spark plug (20) and an ignition control device (34) are assigned to the combustion chamber (3). The ignition control device (34) is fixedly mounted with a portion to the cylinder (2) via one attachment point (40) and is fixedly mounted to the connecting piece (24) via another attachment point (41).

摘要： The invention is directed to a cutter apparatus having a stationary blade and a rotating blade. The rotating blade is driven in rotation by a drive motor. The rotating motion causes the knife and blade to slide relative and over each other in a manner of scissors. The blade and knife each include a plurality of cutting edges with the cutting edges of the knife and blade being so arranged that they run toward each other at an angle opening outwardly. The cutting edges of the stationary blade are formed on radially extending fingers arranged in a star-shaped configuration which facilitates the manipulation of the cutter apparatus and improves the cutting quality thereof. The cutting apparatus is suitable for all kinds of vegetation including leaves and grass blades.

摘要： The invention is directed to an arrangement for actuating a braking device for bringing a motor-driven work tool of a work apparatus to standstill. The braking device is actuated by a brake lever and the brake lever is connected to a pivotably journalled throttle lever via a first actuator. The throttle lever controls the carburetor of the engine driving the work apparatus via a second actuator. In order to bring the work tool rapidly to standstill in idle, the second actuator is attached to a drag lever which is pivotable relative to the throttle lever. After passing through an idle movement path, the throtle lever takes the drag lever along via a follower in a pivot direction.

摘要： The invention relates to a two-handle arrangement for a handheld portable tool having a drive motor and equipped with forward and rearward handles for two-handled operation. Each of these handles includes respective actuating elements which can be actuated only in a specific sequence. First, force must be applied to the actuating element on the forward handle and only when a corresponding actuation of the throttle lever takes place is there an increase in the speed of the drive motor. The invention is especially suited for handheld portable tools equipped with an internal combustion engine such as motor-driven chain saws, hedge trimmers and the like.
