Abstract
An evaporative emission control system is provided which includes an upper valve casing defining a vent conduit, a lower valve casing disposed under the upper valve casing, and a float disposed within the lower valve casing. The float is vertically movable depending upon a liquid level of fuel in a fuel tank, and includes a valve portion that faces the upper valve casing. A valve port formed between the upper valve casing and the lower valve casing is opened and closed by the valve portion of the float. The upper valve casing defines a space between the vent conduit and the valve port. A flow restricting device is disposed in the space of the upper valve casing so as to obstruct flow of fuel from the valve port to the vent conduit.
