摘要： A fuel tank having a fuel inlet pipe which has a normally closed closure valve arranged therein and opened by a fuel pump nozzle. A valve housing is fixed onto the outer wall of the fuel inlet pipe. A cam and a normally closed control valve actuated by the cam and controlling the fluid connection between the canister and the interior of the fuel tank are arranged in the valve housing. The cam shaft of the cam is mechanically connected to the rotary shaft of the closure valve. When the closure valve is opened by the fuel pump nozzle, the control valve is opened by the cam to feed the fuel vapor in the fuel tank into the canister.

摘要： A charcoal canister having an activated carbon layer arranged in a central portion of an interior of the housing in an axial direction thereof and extending over the entire cross section of the interior, which is perpendicular to an axis of the housing. A first chamber is formed in the interior of one axial end of the housing and defined by one end of the activated carbon layer, and a second chamber is formed in the interior at the other axial end of the housing and defined by the other end of the activated carbon layer. A fuel vapor inlet pipe and a purge pipe are connected to the first chamber, and an air inlet pipe is connected to the second chamber. These pipes extend outwardly from a housing wall portion which defines the first chamber.
