HAND-GUIDED TOOL WITH AN INTERNAL COMBUSTION ENGINE AND AIR FILTER Russian patent published in 2017 - IPC F02B63/02 F02M35/24 F02M35/10 

FIELD: engines and pumps.

SUBSTANCE: manually guided tool has an internal combustion engine and air filter, has a cylindrical filter element (39). Filter element (39) onto the ends is tightly connected with end plates. Filter element (39) and end plates separates the dirty side of the air filter from the clean side. Clean side of the air filter at least one channel is connected with an internal combustion engine. First performed as the bottom end plate (40) air filter, which together with the bottom (40) air filter intermediate flange (43) limits the internal space (85), in which the plot of the channel. Intermediate flange (43) is located in the direction of traffic flow between the air filter and engine (15) internal combustion engines. Channel in the inner space (85) is limited by at least one restrictive wall (44) in inner space (85) at an angle to the bottom (40) air filter. Restrictive wall (44) formed at the intermediate flange (43) and/or on the bottom (40) air filter and covers the distance (a) between the head (40) air filter head (60) of the intermediate flange (43), located opposite the bottoms (40) air filter.

EFFECT: avoiding, in large part, the absorption of fuel into the duct.
