  • Patent number: 9303611
    Abstract: A starting device for an internal combustion engine includes a pulley mounted rotatably in a housing which can be set in rotation by a tension means to produce a drive torque for a motor shaft by a starter handle and which is connected to an engaging member by a damping spring. The drive torque is transmitted to the motor shaft to start the internal combustion engine, whereby under torsion of the damping spring, a twisting of the pulley against the engaging member is rendered possible until a stop element impacts against a counter-stop to delimit the twisting, which enables a high operational readiness of the starting device. In the case of a defect of the damping spring, the stop element and/or the counter-stop is formed from a material which has a higher strength than the material of the engaging member and/or the material of the pulley.

  • Patent number: 8973721
    Abstract: The invention relates to a braking apparatus, in particular for implements of motor-driven tool units comprising an arm having at least one bearing disposed therein for rotatable mounting of an axle and comprising a flange fastened on the rotatably mounted axle, wherein the axle and/or the flange are drivable by means of a drive motor, wherein a first friction element is firmly connected on the arm and a second friction element is connected to the axle and/or to the flange, wherein the first and the second friction element come into frictional contact with one another or not depending on the action of centrifugal force on at least one flyweight.

  • Patent number: 8424853
    Abstract: In order to provide an actuating device for a choke valve of a carburetor for motorized equipment, in particular a cut-off grinder, wherein the choke valve is movable between at least a closed position and an open position by an operating element via a mechanical coupling from the operating element to the choke valve, which overcomes the disadvantages of the prior art, it is proposed that the mechanical coupling has a separating arrangement which is in operative connection with the motorized equipment such that the mechanical coupling between the operating element and the choke valve can be interrupted or respectively closed as a function of different operating states of the motorized equipment.
