发明名称 Hand-held power tool with an internal combustion engine
摘要 A hand-held power tool has an internal combustion engine provided with a throttle trigger adjustable between an idle position and a full throttle position. The engine has an operating mode selector adjustable between an operating position and a start position. In an intake passage of the engine, a throttle element is arranged that is in a throttling position when the operating mode selector is in the start position. The throttle element is secured in the throttling position by a locking action. The locking action is released when the throttle trigger is moved from the idle position toward the full throttle position. A restoring element is coupled permanently to the position of the throttle trigger. The restoring element, when the throttle trigger is moved for releasing the locking action, acts on the operating mode selector and restores the operating mode selector from the start position into the operating position.

主权项 1. A hand-held power tool comprising: an internal combustion engine comprising: a throttle trigger adjustable between an idle position and a full throttle position;an operating mode selector adjustable between an operating position and a start position;an intake passage;at least one throttle element arranged in the intake passage, wherein the at least one throttle element, in the start position of the operating mode selector, is in a throttling position, wherein the at least one throttle element is secured in the throttling position by a locking action, wherein the locking action is released upon actuation of the throttle trigger from the idle position in the direction toward the full throttle position;a restoring element coupled permanently to the position of the throttle trigger, wherein the restoring element, when the operating mode selector is in the start position, wherein, in the start position, the at least one throttle element is secured by the locking action, and when the throttle trigger is moved by a force applied by an operator for releasing the locking action, acts on the operating mode selector and restores the operating mode selector from the start position into the operating position by the force applied by the operator on the throttle trigger, wherein the restoring element applies the force applied by the operator on the operating mode selector.
