Latest Patents

Gräter's latest patents include a hand-held power tool with an internal combustion engine. This tool features a throttle trigger that is adjustable between an idle position and a full throttle position. The engine is equipped with an operating mode selector that can be adjusted between an operating position and a start position. In the intake passage of the engine, a throttle element is arranged to be in a throttling position when the operating mode selector is in the start position. The throttle element is secured in this position by a locking action, which is released when the throttle trigger is moved from the idle position toward the full throttle position. A restoring element is permanently coupled to the position of the throttle trigger, ensuring that the operating mode selector is restored from the start position to the operating position when the throttle trigger is activated.

Another significant patent by Gräter is a carburetor assembly that includes an intake channel section and an air channel section. Within the intake channel section, a throttle element and a choke element are arranged, while an air control element is positioned in the air channel section. The assembly features a first coupling unit that defines the position of the throttle element in at least one start position. Additionally, a second coupling unit couples the position of the air control element in at least one operating state to the position of the throttle element. This design ensures a reliable start by holding the choke element in at least one start position through the first and second coupling units.
