Abstract
A fuel vapor processing apparatus is provided for realizing a high desorption performance and a high flexibility in layout resulting from a compact structure including a filter. The processing apparatus comprises a casing formed with a fuel vapor introducing port communicating with the fuel tank, and a fuel vapor discharge port communicating with the intake pipe. A partition is arranged in the casing for defining inside thereof a filter chamber which communicates with an air introducing port for introducing desorbing air from the atmosphere. The partition partitions the casing into a first chamber and a second chamber with a spacing interposed therebetween. The first and second chambers communicate with each other, and also communicate with the filter chamber, the fuel vapor introducing port, and the fuel vapor discharge port. The processing apparatus also comprises a filter contained in the filter chamber for filtering the desorbing air introduced from the air introducing port, and an adsorbent material filled in the first and second chambers for adsorbing the fuel vapor introduced from the fuel vapor introducing port.
