The invention relates to a carburetor arrangement for an internal combustion engine ( ) which drives a work apparatus. The engine ( ) has an intake channel ( ) leading through a carburetor ( ). The intake channel ( ) includes an intake opening ( ) on the side of the carburetor ( ) facing away from the engine ( ). A baffle wall ( ) is provided and covers the intake opening ( ) at least partially. The baffle wall ( ) is mounted transversely to the longitudinal axis ( ) of the intake channel ( ) at a spacing to the intake opening ( ). The baffle wall ( ) and the intake opening ( ) define a baffle enclosure ( ) disposed therebetween. At least a first component part ( ) of the baffle wall ( ) is inclined with respect to the longitudinal axis ( ) of the intake channel ( ) in such a manner that fuel droplets ( ), which exit from the intake channel ( ) and which impinge on the first component part ( ) of the baffle wall ( ), form a fuel film ( ).

Carburetor arrangement

A mold for a plastic grip of a portable tool has two halves with depressions forming the negative. The base body has a top grip extending, when mounted, across the topside of the housing perpendicularly to a longitudinal axis of the tool and a lateral grip connected to the top grip extending therefrom, when mounted, laterally downwardly. The top grip has a first end and the lateral grip has a second end for connecting to the housing. Top and lateral grips have identical elliptical cross-sections rotated to one another in the circumferential direction of the grip by an angle of rotation. Cross-sections have a first diameter larger than a second diameter. Mold depressions have recesses for molding elongate, raised portions in the longitudinal direction. Recesses are adjacent circumferentially and extend spirally. Separation surfaces of mold halves are positioned in a longitudinal center plane of a recess adjacent the first diameter.

Grip for a portable hand-guided working tool and molding same

A manually guided implement having an internal combustion engine and a carburetor for supplying the engine with a fuel/air mixture is provided. A combustion air stream is drawn in through the carburetor by the engine. A warming medium heated up by the engine can be passed along the outer surfaces of the carburetor separate from the combustion air stream.

Manually guided implement having an internal combustion engine

An anti-vibration element is provided for disposition between a motor unit and a handle unit of a manually guided implement. The anti-vibration element includes a sleeve-shaped, elastic main body as a vibration damper, with one end portion of the main body being adapted to be disposed in a receiving recess of the motor unit, and the other end portion being adapted to be disposed in a receiving recess of the handle unit. Respective plugs are disposed in the end portions of the main body for non-detachably holding such end portions in the receiving recesses. A cable that serves as a coupling element for preventing separation of the plugs is provided and spans an axial spacing between the plugs and extends through the main body. Each of the end regions of the cable has a respective fitting, an axially inwardly facing end face of each such fitting positively engaging behind an edge of an adjacent one of the handle unit and the motor unit.

Anti-vibration element having separation securement

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