  • Patent number: 11808244
    Abstract: An internal combustion engine of a motor vehicle includes an output shaft and a spring element which can rotate with the output shaft which is to be tensioned as a result of a deactivation of the internal combustion engine by a rotation of the output shaft, where a spring force can be provided by the spring element and where by the spring force the output shaft can be set into rotation in the event of a start following the deactivation. Via a locking device the output shaft is to be secured against a rotation after tensioning the spring element and while the spring element is tensioned. A blocking device can be shifted between a blocking state securing a first part of the spring element, which has a second part non-rotationally connected to the output shaft, against a rotation and a release state releasing the first part for a rotation.

    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: 8944021
    Abstract: The invention pertains to a device for starting an internal combustion engine for handheld equipment such as chain saws, lawn mowers, lawn trimmers and the like, or for vehicles such as mopeds, boats or miniature aircraft. The starting device features an output element into which a starter torque can be introduced when the starting device is actuated. The output element is functionally connected to a crankshaft of the internal combustion engine in order to introduce a crankshaft torque therein. The functional connection between the output element and the crankshaft introduces variable crankshaft torque into the crankshaft depending on the rotational angle of the crankshaft at a constant starter torque. This advantageously improves force or torque characteristics for largely operating the starter device independently of the compression phase and the expansion phase of the internal combustion engine.

    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: 8061322
    Abstract: A starting system for a combustion engine including a carburetor with a throttle valve moveable between idle and wide open positions, a throttle control to control movement of the throttle valve during normal operation of the engine, and a linkage between the throttle control and the throttle valve. The starting system includes a recoil pulley, a pull-cord to rotate the recoil pulley, an actuator moveable in response to rotation of the recoil pulley, and a throttle override device. The throttle override device has a first control member moveable from a first position to a second position in response to movement of the actuator, and a second control member moveable in response to movement of the first control member from a first to a second position. The second control member is operably associated with the linkage to prevent the throttle valve from being in its wide open position when the second control member is in its second position.

  • Patent number: 7963266
    Abstract: A starter device for an internal combustion engine (10) has an actuating device and an entrainer (24) can be coupled to the crankshaft (13) of the engine (10). The entrainer (24) and the actuating device are rotatably journalled about a rotational axis (14). The entrainer (24) and the actuating device are connected to each other via a damping spring (23). The damping spring (23) is connected with a first end (26) to the actuating device and with a second end (27) to the entrainer (24). The entrainer (24) and the actuating device have respective supports (21, 42). The damping spring (23) is mounted on the outer periphery of the two supports (21, 42). In the direction of the rotational axis (14), a disc (22) is mounted between the two supports (21, 42) in order to avoid the situation that the damping spring (23) can force itself into a gap between the two supports (21, 42) which gap can arise during operation.

  • Patent number: 7934481
    Abstract: Flywheel starter pulley attachment apparatuses and methods are disclosed for a flywheel rotatable about an axis and a starter pulley rotatable about the same axis as the flywheel. One or more retainers can be provided to couple rotation of the starter pulley to the flywheel and/or a cooling fan element attached thereto. Each of the retainers can be configured for at least a portion of the retainer to pass through an opening in the starter pulley. Each retainer can include a body portion and a fin portion, the fin portion extending outwardly from the body portion. The fin portion can further include a protruding lip disposed between first and second edges of the fin portion, for example, forming an angle of from about 100° to about 180°. The protruding lip can be configured to engage the starter pulley when the retainer is positioned through the opening of the starter pulley to secure the starter pulley in place where rotational movement of the flywheel assembly can occur in either direction.

    Abstract: The invention pertains to a device for starting an internal combustion engine for handheld equipment such as chain saws, lawn mowers, lawn trimmers and the like, or for vehicles such as mopeds, boats or miniature aircraft. The starting device features an output element into which a starter torque can be introduced when the starting device is actuated. The output element is functionally connected to a crankshaft of the internal combustion engine in order to introduce a crankshaft torque therein. The functional connection between the output element and the crankshaft introduces variable crankshaft torque into the crankshaft depending on the rotational angle of the crankshaft at a constant starter torque. This advantageously improves force or torque characteristics for largely operating the starter device independently of the compression phase and the expansion phase of the internal combustion engine.
