摘要:
An internal combustion engine having a cylinder, a fuel-supply mechanism, and an elastic connector for connecting the fuel supply mechanism to the cylinder. The connector has a first channel for fuel/air mixture and a second channel for combustion air. The connector has a first connection end and a second connection end at which the two channels open out. The two channels are separated from one another by a partition that extends in the longitudinal direction of the channels. The partition is twisted about its longitudinal central axis between the first and second connection ends to achieve a great elasticity of the connector. To produce the elastic connector, a respective core is used for each channel, and the cores are moved relative to one another to enable removal of the connector from a mold.

摘要:
A manually guided implement having a tool and a brake mechanism for the tool. The brake mechanism includes a brake band that is looped about a brake drum. The brake band and the brake drum form abrasion partners that cooperate with one another during a braking process. At least one of the abrasion partners has a coating. The coating is provided with diamond particles that are embedded in a matrix that contains nickel. The coating is effected in a nickel bath in which the diamond particles are dispersed.
