Abstract
In a canister for a fuel evaporative emission control system of an automotive vehicle, a deflector of the conical frustum shape is embedded in the adsorbent layer of the canister. A diameter of the deflector gradually increases upwardly and a bottom of the deflector faces to the end of the inlet conduit. Dimensional relations of various parts of the deflector are specified. The deflector may include a check valve mounted on the underside of the bottom of the deflector.
