Abstract
An apparatus for adsorbing fuel vapor having a fuel vapor inlet hole communicating to a fuel tank, a mixed gas outlet hole communicating to the intake passage for internal combustion engine, an inlet hole for the desorbent air communicating to the atmospheric air and an adsorbent for adsorbing fuel vapor and by using, as to the adsorbent which is at least partially foamed body of active charcoal constituting a three-dimensional network cell structure having an inner communicating space between granular active charcoals.
Claims5
An apparatus for adsorbing fuel vapor comprising:
- a container having side walls and opposed ends;
- a fuel vapor inlet in one of said ends for introducing the fuel vapor into the container;
- a gas outlet in the other if said ends for taking the air-fuel mixture out from the container;
- and air inlet for introducing the air into the container for desorbing the fuel vapor;
- an adsorbent being set in the container, for adsorbing the fuel vapor said adsorbent containing a foamed body of active charcoal constituting a three-dimensional network cell structure having an inner communicating space;
- and a thin sleeve of active charcoal snugly surrounding the foamed body between the latter and said side walls.
