Two-stroke motor with fresh-gas supply and flange for a two-stroke motor

A flange for a two-stroke motor with fresh-gas supply, wherein the flange comprises a first front surface and a second front surface, a first conduit segment, and a second conduit segment,

• wherein the motor comprises a motor housing which comprises a crank chamber having an inlet opening and a cylinder chamber having an outlet opening, wherein the crank chamber comprises a crank drive and the cylinder chamber comprises a piston, which crank drive and piston are connected by a connecting rod,
• at least one overflow conduit,
• a carburetor comprising a carburetor chamber that comprises a fresh-air entrance opening, a fuel entrance opening and a mixture exit opening, a regulatable throttle flap, an inlet conduit connecting the mixture exit opening and the inlet opening of the crank chamber, and a fresh-gas conduit comprising an opening to the overflow conduit,
• wherein the fresh-gas conduit and the carburetor chamber are connected in such manner that the throttle flap is controllable and the direct supply of fresh gas to the overflow conduit is controlled thereby,
• wherein the throttle flap can be brought into a first open position in which the throttle flap is fully open and separates the carburetor chamber at least partially into a mixture chamber section with the fuel entrance opening and into a fresh-air chamber section,
• wherein a starter flap is positioned in close proximity to the fresh-air entrance opening of the carburetor chamber, which starter flap is adjustable so that when it is in a fully open position it is essentially in a plane with the throttle flap when the throttle flap assumes the first open position,
• wherein the first conduit segment extends through the flange and comprises an entrance opening in the first front surface and an exit opening in the second front surface, and the flange is fastened to the carburetor by the first front surface and is fastened to the motor housing by the second front surface,
• wherein the second conduit segment comprises a branch conduit that comprises at least one exit opening, which branch conduit is accessible through the entrance opening of the first conduit segment.
