摘要： A guide frame (1) for an earth drilling apparatus includes a support plate (6) for holding the drive unit (7) and a handle frame (2) having handle sections (17, 18) for holding and guiding the earth drilling apparatus. Operator-controlled elements (19a, 19b, 19c) for controlling the drive unit (7) are arranged in the region of the handle section (18). The handle sections (17, 18) of the handle frame (2) lie in a plane (5) above the support plate (6). The handle frame (2) encloses the drive unit (7) as a closed frame and is connected via a carrier frame (8) to the support plate (6). The carrier plate (8) is fixed to the handle frame (2) via several coupling elements (20). Each coupling element (20) includes a vibration damper (24) which is arranged between the carrier frame (8) and the handle frame (2). In this way, the handle frame is decoupled by the carrier frame from the drive unit with respect to vibration without affecting the bracing of reaction forces via the handle frame.

摘要： A two-cycle engine is provided, especially in a manually-guided implement such as a power chain saw, a brush cutter, a trimmer or the like, and has a cylinder in which is formed a combustion chamber that is delimited by a reciprocating piston that, via a connecting rod, drives a crankshaft that is rotatably mounted in a crankcase. In prescribed positions of the piston, the combustion chamber is connected with the crankcase via at least two transfer channels. At least one air channel is provided that opens out at an air channel window at the cylinder in the region of the piston, and that, in prescribed positions of the piston, is connected with at least two transfer channels via a piston window formed in the piston. To achieve a good scavenging of the combustion chamber, and hence low exhaust gas values of the engine, structural features are provided on the piston window for the defined distribution of air to the transfer channels.

摘要： The invention relates to a vibration damper between a housing (4), which holds an internal combustion engine, and a handle (3) fixed on the housing (4). The handle (3) is for holding and guiding the motor-driven chain saw (2) during use thereof. The vibration damper (1) is a coil spring (5) which is fixed at a first end (10) thereof with an attachment element (7) to the handle (3) and, at a second end (20), the coil spring is fixed with a further attachment element (30) to the housing. A part turn of the end (10, 20) of the coil spring (5) is held form-tightly to the attachment element (7, 30) in the direction of its longitudinal center axis (25). To provide a torsion-free assembly of the coil spring, it is provided that the coil spring (5) can be assembled from one of its ends (20) between the handle (3) and the housing (4) and be secured at least at one of its ends (20) to the attachment element (30) against a rotational movement in the peripheral direction.

摘要： A hand-guided working tool has a telescopic rod with a first and a second end. A drive motor is connected to the first end of the telescopic rod. A working tool, connected to the second end of the telescopic rod, is driven by the drive motor. The telescopic rod includes an outer tube and an inner tube inserted with an inner end into the outer tube and displacable in the longitudinal direction of the telescopic rod. A first clamping member is connected to the first end of the outer tube for fixing the axial position of the inner tube. The inner tube has an outer mantle surface and the outer tube has an inner circumferential surface. The outer mantle surface is spaced at a radial distance from the inner circumferential surface. A first cylindrical bearing body is supported on the inner end of the inner tube. The first bearing body is displacably supported in the outer tube. The first clamping member has an inner circumferential guide surface matching the outer mantle surface of the inner tube such that the inner tube is secured coaxially relative to the outer tube by the first clamping member and the first bearing body.

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： The invention is directed to a starting device for manually starting an internal combustion engine and especially a two-stroke engine. The starting device comprises essentially a clutch drum which is actuated by a pull rope for imparting rotation to a catch which coacts with a clutch element of the engine shaft. The starting device maintains within limits the effects of stronger fluctuations of the reaction torque of the engine shaft on the hand of the operator. This is achieved in that the clutch drum and the carrier of the catch are configured as separate parts and are connected by an elastically-deformable entraining element which takes up the force peaks of the reaction torque.

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.
