Abstract
A fuel vapor recovery canister having a housing including an outer wall with spaced-apart vapor ports. Adsorbent material in the housing adsorbs and stores fuel vapors entering one vapor port, or under other circumstances releases such vapors for exit through one of the ports. In one embodiment the housing has interleaved baffle plates between the ports, which force vapors entering one port to flow along a serpentine path, giving maximum exposure of the vapor to the adsorbent material. In a second embodiment, a helical partition is provided, similarly forcing vapor flow to occur along a serpentine path.
