Abstract: A contact plug for direct electrical contacting of contact surfaces is provided on both sides of a circuit board. The contact plug includes two flexibly interconnected contact carriers, which form, between each other, a plug receptacle for the circuit board and each have at least one contact element extending into the plug receptacle. A spring is provided whose two free spring legs engage over the two contact carriers i the insertion direction of the contact plug and bias them in the direction of each other. A control channel, which is formed between the two contact carriers nd laterally adjacent to the plug receptacle and, in cooperation with a control wedge provided on the circuit board, pivots the two contact carriers open in opposition to the action of the spring upon insertion of the circuit board. A seal seals the two contact carriers in a mating contact plug on the reverse side. The two free spring legs of the springengage over the two contact carriers in the insertion direction of the contact plug.

Abstract: A silencer includes a silencer inlet followed by a flow channel. The inlet can be attached to an outlet of a combustion chamber of a two-stroke engine. The flow channel at the channel end located opposite the silencer inlet leads into a first chamber where a second chamber is provided into which exhaust gas flows through a main outlet branched off the flow channel. The second chamber preferentially encloses the first chamber. The flow channel is flow-favourably moulded between the silencer inlet and the first chamber so that the exhaust gas flowing into the silencer inlet, because of its mass inertia, predominantly flows into the first chamber and, after filling the first chamber, flows back again in the direction towards the combustion chamber. The silencer allows a piston of the engine to include a piston skirt that is substantially designed closed.
