Abstract

PURPOSE: To heighten the adsorption and desorption of evaporated fuel in an evaporated fuel stopper for an automobile, by providing a check valve in the stopper so that the valve is opened only when negative intake pressure is generated.
CONSTITUTION: An opening 32, which is connected to a carburetor not shown in the drawing, and another opening 33, which is connected to a gasoline tank not shown in the drawing, are provided at the top and bottom of a main body housing 31 in which activated charcoal 36 is packed. The activated charcoal 36 is supported by latticelike rings 38 fitted with filters 37 and hollow filter members 34 pushed by a coiled spring 39. A check valve 35 is installed in the center of the activated charcoal 36. When the valve 35 is opened, the interior communicates with the opening 32. The valve 35 is opened by the transmission of negagive intake pressure to the opening 32.
