A device for controlling evaporative emission from an automobile, which device comprises, a casing accommodating fuel gas absorbing agents, a tank port adapted to communicate with a fuel tank of the automobile and having a first check valve for permitting the flow of fuel gas from the fuel tank into the casing, and a purge port adapted to communicate with an internal combustion engine and having a second check valve for permitting the flow of fuel gas from the casing to the engine. Each of the check valves of the first and second check valves comprises a check ball of metal, and a valve seat engaging with the check ball and being made of thin metal plate formed in one body with a reinforcement of plastic.

Device for controlling evaporative emission from an automobile

A device for preventing evaporative fuel loss comprising a casing which accommodates fuel gas absorbing agents. The casing is divided into three slender compartments by means of two partitions. A flow-in chamber is disposed at the entrance of the first compartment and is communicated with a fuel tank. Two dispersing chambers communicate the outlet of the first compartment and the inlet of the second compartment, and the outlet of the second compartment and the inlet of the third compartment, respectively. An atmospheric chamber is disposed at the exit of the third compartment and has an atmospheric port for flowing in purge air and for discharging filtered and clean air.
