Filed: 1992-10-20
Abstract: PURPOSE:To provide a flow changeover valve with a simple structure and a low cost which can make purge adjustmeal so that no great amount of evaporated fuel may enter into an engine intake pipe. CONSTITUTION:A changeover valve body 3 is installed between an absorption chamber 21 filled with organic polymeric gel 4 and a space chamber 22.
