Abstract: In order to secure wired components of large mass or non-uniform mass distribution safely on a circuit board, without the components needing, as currently usual, to be glued onto the circuit board or held on the circuit board with snap-in holders, integrated into a connection bore for receiving a connection wire, or pin, of an electronic component a holding mechanism for secured holding of the connection wire, or pin. The holding mechanism represents a narrowing in the connection bore to a diameter smaller than that of the connection wire, or pin. The holding mechanism can be implemented, for example, by a connection bore embodied in the form of a bore drilled from one side of the circuit board, not completely through the circuit board. In such case, edge remains as a narrowing, which securely seizes the connection pin of the relevant component and holds the component fixed to the circuit board.

Abstract: A two-stroke engine with external fuel mixture generation in a carburetor. The engine including a suction funnel having an interior disposed upstream of the carburetor. The engine further includes a tapered insert having a narrow end and a wide end disposed in an area of an inlet port of the suction funnel. The insert at least partially defines the interior of the suction funnel, and the insert tapers in a flow direction of air flow from the wide end to the narrow end. Accordingly, a diameter of the interior of the suction funnel adjacent to the narrow end of the insert is substantially larger when compared to the narrow end of the insert.

Abstract: A muffler has a housing (2) through which exhaust gas flows and which has at least one housing chamber (3, 5) and in which deflecting elements (13 to 16) serving to make the gas swirl are arranged spaced one behind another along a main axis (19?) of the housing in a positionally fixed manner. A disk-shaped body (17?) having guide vanes (18) with slots (18?) therebetween is provided as each deflecting element (13 to 16) and extends over the clear cross section of the housing (2). The guide vanes of adjacent disk-shaped bodies respectively deflect the flow in opposite directions about the main axis (19?) of the housing.

Abstract: The invention relates to a muffler, particular for internal combustion engines, having a housing (2) trough which a flow medium flows and which has at least one housing chamber (3, 5) and in which deflecting elements (13 to 16) serving to make the flow medium swirl are arranged one behind another along a main axis (19′) of the housing and in a positionally fixed manner at a distance from one another, wherein a diskshaped body (17′) having slots (18′) is provided as deflecting element (13, 14, 15, 16) and extends over the clear cross section of the housing (2), and wherein guiding elements (18) which bound the slots (18′), are in the manner of guide vanes and belong to adjacent, diskshaped bodys (17′) deflect the flow in different directions with respect to the main axis (19′) of the housing.
