摘要： PROBLEM TO BE SOLVED: To prevent vehicle parts from interfering with each port of a canister and prevent each port from being damaged at the time of vehicle collision. SOLUTION: Ports 17, 19 and 21 are placed on an upper surface of the canister 1. An introduction path 16 introducing evaporative fuel into an adsorption material layer is raised on the upper surface of the canister 1, while an evaporative fuel communicating chamber 24 is protrusively provided so that it surrounds an external portion of the raised portion. An element wall 23 of the evaporative fuel communicating chamber 24 is disposed so that it encloses each port 17, 19 and 21 on three sides of the canister 1 except one side. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply device having check valves capable of hindering the fuel having flowed out of a cutoff valve from influx into check valves and preventing the check valves from dropping in its function by arranging so that the fuel returns into a fuel tank again when the cutoff valve is opened. SOLUTION: The upper opening ends 5a, 6a, 7a of the check valves 5, 6, 7 are positioned a certain dimension higher than the upper opening end 4c of the cutoff valve 4, and the fuel overflowing from the cutoff valve 4 is allowed to stagnate in the upstream of the check valves 5, 6, 7 so as not to flow into them, and thereby the influx of the overflowing fuel to the check valves 5, 6, 7 is suppressed, and attachment of viscous substances to their valve element parts is decreased, to lead to suppression of a drop of the valve function.

摘要： PROBLEM TO BE SOLVED: To provide a canistor which can efficiently capture and separate a large amount of vapor fuel generated in a fuel tank, and keep a satisfactory on-vehicle property. SOLUTION: A canistor 1 has activated carbon chambers 19, 20 for capturing vapor fuel generated in a fuel tank. The canistor 1 has a vapor passage 3 for introducing the vapor, a breather passage 12 for introducing the vapor remarkably generated at the time of oil supply, a purging passage 14 for purging the captured vapor, and an atmospheric side control valve 30 for communicating the inner space of the canistor 1 with the outside. The breather passage 12 and the purging passage 14 are communicated with an outside diffusion chamber 62 arranged outside the canistor 1. The outside diffusion chamber 62 is further communicated with a diffusion chamber 61 inside the canistor. The vapor largely introduced through the breather passage 12 at the time of oil supply is evenly and steppedly diffused. It is also poosible to improve adsorption efficiency of the vapor to an activated carbon layer 22, through the diffusion chamber 61 and a filter.

摘要： PROBLEM TO BE SOLVED: To provide a fuel feed device capable of restricting abnormal noise caused by vertical vibration of a reservoir cup even when a sliding engagement part is exposed above a liquid surface.
SOLUTION: A return hole 2a is provided at a center part of a connection tube 2b, and a liquid sump groove 2c to store fuel is at a sliding outer circumferential part of it. A communication hole 2d to communicate the liquid sump groove 2c with the return hole 2a is provided. A communication hole 4b communicating with the reservoir cup 4 is provided in a bottom part of a connection hole 4a. The return hole 2a is thus usable as a fuel return passage. Since the sliding engagement part 5 is constantly lubricated with return fuel, generation of abnormal noise caused by vertical vibration of the reservoir cup 4 can be restricted even when the sliding engagement part 5 is exposed above the liquid surface of fuel.

摘要： PROBLEM TO BE SOLVED: To provide a fuel feeder in which the wave motion of the fuel level caused when a vehicle makes a rapid turn, and the height of the fuel feeder can be suppressed to be low. SOLUTION: Since a cut-off valve 4 is surrounded by a canister 5, the wave motion of the fuel level generated when the vehicle makes a rapid turn is checked by the canister, and the wave motion is not transmitted directly to the cut-off valve. Therefore, when the fuel level is elevated, the vertical motion of a float valve constituting the cut-off valve is reduced, a valve part is less opened, outflow of the fuel to the canister is suppressed, and degradation of the adsorption performance of the canister is suppressed. In addition, the height of the canister to the predetermined volume is reduced, and the height of the total fuel feeder can be suppressed. The height of a fuel tank can be further suppressed.

摘要： PROBLEM TO BE SOLVED: To extend the life of active carbon by decreasing the amount of gasoline vapor that enters a diffusion chamber of a canister from a gas-liquid separation chamber while facilitating condensation of the vapor phase fuel from the fuel tank in the gas-liquid separation chamber. SOLUTION: Vapor phase fuel from a fuel tank 24 enters a gas-liquid separation chamber 21A via a tank port 13A from an evaporation fuel duct 23. Since the inside diameter of a canister communicating port 22A is small, gasoline vapor is inhibited from entering a first diffusion chamber 12 from the separation chamber 21A, and condensation in the separation chamber 21A is promoted. When the fuel tank 24 cools and the internal pressure becomes negative, the flow of the liquid phase fuel of the separation chamber 21A reverses and storage of a large amount of liquid phase fuel in the separation chamber 21A is prevented. Therefore, the life of the active carbon 10 in the diffusion chambers 12, 14 is extended.

摘要： PROBLEM TO BE SOLVED: To make a float valve difficult to float in a gas and easy to float in a liquid while suppressing the enlargement in size. SOLUTION: A seat plate 40 for mounting the float valve 5 has a lower hole 43 communicating with the inside and outside of a cylindrical part 41 for housing the float valve 4. The cylindrical part 41 has a horizontal hole 44 communicating with the inside and outside of the cylindrical part 41 on the side circumferential wall, and part of the side circumferential wall of the cylindrical part 41 is interposed in a passage extending from the lower hole 43 to the horizontal hole 44. When the opening area of the lower hole 43 and the horizontal hole 44 is sufficiently ensured, the inflection of the passage never causes a large resistance or pressure loss, and the force for floating the float valve 5 can be minimized. In a liquid fluid, since inertial force acts thereon according to its viscosity and mass, the kinetic vector before causing the inflection is kept even if the passage is inflected, and the force for floating the float valve 5 can be worked.

摘要： PROBLEM TO BE SOLVED: To surely prevent a liquid fuel leaked from the valve hole 70 of a double float valve 5 from running toward a canister. SOLUTION: A cylindrical liquid receiving part 11 having a diameter larger than the aperture of the valve hole 70 protruded toward an evaporator opening 31 is formed on the inner surface opposed to the evaporator opening 31 of a cover 1. The liquid fuel blown out from the valve hole 70 through the evaporator opening 31 is collided to the cylindrical liquid receiving part 11, guided by the side wall of the liquid receiving part 11, fallen down, and returned to the fuel tank 100 through the evaporator opening 31.
