Fuel system of a handheld work apparatus |
摘要 |
The invention relates to a fuel system of a portable handheld work apparatus driven by an internal combustion engine. The fuel system includes a fuel tank (2), a fuel pump, a fuel line (4) leading from the fuel tank (2) to the fuel pump and a first suction head (5) which is disposed at an end (7) of the fuel line (4) at the fuel tank. At least a second suction head (6) is arranged within the fuel tank (2) and is connected in the fuel line (4) in series ahead of the first suction head (5). The second suction head (6) has an external suction surface which is formed by a porous covering (9). The porous covering (9) delimits a suction space. A guide is arranged in the suction space which guides the through-passing fuel flow at least approximately along the entire inner surface of the porous covering (9). |
