Abstract: A diaphragm carburettor is connected via a suction port with the clean air side of an air filter. A regulating chamber with a fuel chamber is connected with the suction port, in which the fuel chamber is acted upon with underpressure from the suction port and is separated from a compensation chamber by a regulating diaphragm formed to control the fuel supply to the fuel chamber. The compensation chamber is connected via a compensation path with the clean air side of the air filter and/or with the suction port so that pressure vibrations are reduced in the compensation chamber. A control and/or regulating element associated with the compensation path alters the length and/or the diameter of the compensation path.

Abstract: A silencer for a two-stroke engine includes a first chamber and a second chamber, wherein a flow channel is provided between an outlet of a combustion chamber and the first chamber. A high charge degree of the combustion chamber has a pressure ratio in the region of the outlet which reduces or prevents an escape of fresh gas from the combustion chamber. The flow channel between the outlet and the first chamber is flow-favorably shaped in such a manner that the exhaust gas that flows out of the outlet because of its mass inertia predominantly flows into the first chamber and following charging of the first chamber flows back again and as a result a back pressure is formed in the direction of the combustion chamber.

Abstract: A damped guiding unit for a portable implement includes a connection element arranged at one end of a guide rod element, for connection of a tool element for the sawing, cutting and/or scything of undergrowth or of grass. A damping element is arranged on the connection element for the damping of oscillations or vibrations caused by the tool element. A holding element is arranged on the guide rod element for holding the portable implement. The holding element and the connection element are structural elements which are respectively separated from each other in that the holding element is associated with a first assembly and the connection element is associated with a further assembly separated from the first assembly. The holding element is further arranged at a distance from the connection element between the one end and the other end of the guide rod element, so that both a direct guiding of the portable implement and also an intensive vibration damping of the holding element is achieved.

Abstract: In order to provide a two-stroke motor, in particular for a portable, hand-guided working device with a combustion space formed in a cylinder and a piston guided in the cylinder so that it performs a lifting movement, at least one transfer port is provided which is formed at least from a combustion-space-side opening section, a rising section and a crankcase-space-side inlet section. The opening section is connected to the inlet section by the rising section arranged approximately parallel to the piston barrel. The motor has a small flow resistance because of its geometric design, despite maintaining small opening windows into the combustion space, and allows simple casting production. The transfer port forms in the inlet section a whole port which passes in a single-flow manner into the rising section and is divided by a division at least into a first partial port and a second partial port at least in the upper region of the rising section adjoining the opening section.
