An apparatus for treating fuel vapor, such as in a motor vehicle fuel tank, by subjecting it to adsorption treatment to prevent its direct emission into the atmosphere. The apparatus according to the present invention comprises a fuel tank, a partitioning wall provided within the fuel tank to define a small fuel storage chamber within the fuel tank, a canister container housed in the small fuel storage chamber, the canister container storing therein a fuel adsorbing material. When fuel feeding takes place, feeding fuel is introduced into the small fuel storage chamber to cool the canister container. However, when the engine is operated, high temperature return fuel is introduced into the small storage chamber to heat the canister container thereby promoting the adsorbing and de-adsorbing action of fuel by the fuel adsorbing material.

Device for controlling evaporative emission from a fuel tank

A temperature-detection type change-over valve for switching the state of communication between a plurality of passages, suitable for use in combination with a controller for controlling the operation of an internal combustion engine. The valve has a thermally expandable member adapted to expand when heated, a shaft adapted to be pressed and moved in one direction as the thermally expandable member expands, a valve movable following the movement of the shaft between a first and a second position for switching the state of communication of passages, and a tension spring disposed to surround the shaft and adapted to exert a biasing force to act against the force generated by the expansion of the thermally expandable member.

Temperature-detection type change-over valve

A hose connector having a couple of connecting plates to which the hose should be connected, gasket put between the plates to be pressed against the plates, a couple of slightly curved plate pressures put on the plates opposite to the gasket and fixing means for fixing the above elements all together, pressing and flattening the plate pressures inwardly for connecting the hose via the plates with high sealing function and low cost.
