ADSORBER-DESORBER Russian patent published in 2005 - IPC

FIELD: mechanical engineering; engines.

SUBSTANCE: invention relates to fuel mixture supply systems and it can be used as trapping and absorbing device of fumes evaporating from fuel tank and float chamber of carburetor and subsequent return of fuel fumes by blowing adsorbent with atmospheric air. Carcass-type adsorber-desorber of fuel fumes has at least body cover, adsorption unit and intake chamber coupled by intake pipe with fuel tank and pipe for blowing through, with suction manifold of internal combustion engine, both pipes passing through body cover. Intake chamber is formed between adsorption unit and body cover, end of intake pipe and end of blowing through pipe are separated from adsorption unit by diaphragm dividing intake chamber into upper and lower spaces. Intake end of blowing through pipe is arranged close to cover surface, and one or several branch pipes are built into diaphragm, first ends of branch pipes being fitted-in for communication with lower space, and second ends are found in upper space close to surface of cover.

EFFECT: prevention of suction of condensate into engine suction manifold.
