ADSORBER OF FUEL EVAPORATION CONTROL SYSTEM Russian patent published in 2002 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to vehicles furnished with internal combustion engines, particularly, to engine fuel systems, and namely, to adsorbers of fuel evaporations from fuel tank. proposed adsorber has cylindrical housing 1 limited by cover 2 and bottom 3. Housing 1 accommodates adsorbing material in form of solid block 4 installed with clearance relative to inner side wall of housing. Cover 2 is provided with three branch pipes placing block 4 in communication with atmosphere, fuel tank and engine air intake system. Centering ring projections 8 and 9 are made on cover and bottom. Projections are pointed inside housing, come in contact with block and provide required clearance.
