摘要： A refueling pipe structure of a fuel tank includes a tank body, and an a refueling pipe which is connected to the tank body to extend upwardly therefrom. The refueling pipe is provided at its upper end with a refueling port into which a refueling nozzle can be inserted. The structure includes a flow direction limiting device mounted within the refueling pipe in the vicinity of the refueling port for guiding a fuel flow from a tip end of the refueling nozzle toward an inner surface of the refueling pipe, while limiting the fuel flow in a gyrate direction along the inner surface of the refueling pipe. Thus, the generation of evaporated fuel within the refueling pipe during refueling can be inhibited, and fuel can be smoothly introduced into the tank body.

摘要： A vaporized fuel control valve for a fuel tank containing fuel to be supplied to an internal combustion engine, having a casing fastened to an upper surface of the fuel tank, and a float valve is housed in the casing such that it moves upward toward a seat in response to fuel level in the fuel tank. A diaphragm valve having a diaphragm is placed in the casing above the float valve for separating an interior of the casing to a first chamber communicating with a filler pipe of the fuel tank, and a second chamber communicating with the fuel tank through the float valve. The diaphragm valve opens to connect the second chamber with a canister such that vaporized fuel forced out of the fuel tank flows along a path through the float valve to the canister when the first chamber is supplied with atmospheric pressure, unless the float valve seats on the seat. In the valve, an intercepter such as a filter is placed in the path to intercept a fuel spray produced due to an impact when the float valve has seated on the seat, so as the fuel spray not to adhere to the diaphragm. As the interceptor, various partitions different in shape are used. With the arrangement, adherence of sprayed fuel, which otherwise degrades the diaphragm, is prevented.

摘要： A float valve mounted to a tank body made of a synthetic resin. A welding flange provided on a cover made of a synthetic resin having a large swelling rate is welded to an outer periphery of an opening defined in an upper wall of a tank body made of a synthetic resin having a large swelling rate, so that the cover covers the opening, and a fixing flange provided at an upper portion of a protector having a small swelling rate for supporting the float case of the float valve by a concavo-convex engagement is fixed between the outer periphery of the opening of the tank body and the welding flange of the cover. The protector is formed of the synthetic resin having the small swelling rate and, hence, it is possible to reliably prevent the float case from being dropped out due to the swelling of the protector. In addition, the protector is fixed with its mounting flange sandwiched between the tank body and the cover and hence, the protector can be fixed firmly, while effectively absorbing a difference between the swelling rates.

摘要： Blockage of a drain pipe of a canister due to freezing or clogging with mud is prevented with a simple structure comprised of a small number of parts. A drain pipe, mounted to a canister body having an adsorbent accommodated therein, includes an inner shell which extends downwards from the canister body and opens at its lower end, and an outer shell which opens at its upper and lower ends. The lower end of the inner shell is inserted into the opening in the upper end of the outer shell with a gap left therebetween. Even if the opening in the lower end of the outer shell is blocked due to freezing or clogging with mud, surplus fuel or the exterior air can flow from the canister body via the opening in the upper end of the outer shell. If the opening in the lower end of the outer shell is submerged in water when evaporated fuel is purged into intake system, the drawing of water into the canister body can be prevented, because the opening in the upper end of the outer shell opens into the atmosphere.

摘要： A canister system is installed in a vehicle having a body having a substantially closed space defined therein, and a subframe mounted on the body and having a substantially closed space defined therein. An air intake passage is connected to a canister for drawing and delivering fresh air into the canister, and an air exhaust passage is connected to the canister for exhausting air resulting from removal of evaporative fuel components from an evaporative fuel-air mixture by adsorption of the evaporative fuel components by the canister into the atmosphere. An open end of the air intake passage remote from the canister is formed in the body of the vehicle, and an open end of the air exhaust passage remote from the canister is formed in the subframe.

摘要： An on-off valve 30 is mounted in an intermediate portion of a first evaporative fuel conduit 24 for passing an evaporative fuel within a fuel tank 21 to a canister C. The on-off valve 30 is opened when refueling. A float valve 28 is mounted at a lower end of the first evaporative fuel conduit 24 and closed by rising of the liquid level in the fuel tank 21. A two-way valve 40 and a second float valve 29 are mounted in an intermediate portion and a lower end of a second evaporative fuel conduit 25 which permits the fuel tank 21 and the canister C to be put into communication with each other during non-refueling. By putting the first and second evaporative fuel conduits 24 and 25 into communication with each other by a communication passage 27, the internal pressure in a portion 24a of the first evaporative fuel conduit 24, between the on-off valve 30 and the second float valve 28, is equalized to the internal pressure in the fuel tank 21, thereby preventing the first float valve 28 from being stuck in a closed position.

摘要： An evaporative emission control system for an internal combustion engine comprises a canister for adsorbing evaporative fuel generated in the fuel tank, and a first evaporative fuel passage extending between the canister and the tank main body of the fuel tank. A differential pressure-operated valve is arranged across the first evaporative fuel passage, which has a positive pressure chamber communicating through the first evaporative fuel passage with the interior of the tank main body of the fuel tank, and a back pressure chamber. The differential pressure-operated valve opens and closes the first evaporative fuel passage in response to a difference in pressure between the positive pressure chamber and the back pressure chamber. A pressure-introducing passage extends between the back pressure chamber and the inlet end portion of a filler pipe extending from the interior of the main body of the fuel tank, and a second evaporative fuel passage extends between the interior of the tank main body of the fuel tank and one of the back pressure chamber and the pressure-introducing passage. A check valve limits the amount of evaporative fuel flowing through the second evaporative fuel passage.

摘要： In an evaporative fuel processing device, a constriction is provided in a refueling line 1 for a fuel tank T and connected to a diaphragm actuator through a negative pressure tube. When fuel passes through the constriction during refueling, the diaphragm actuator causes a switch-over valve 5 to be switched by the action of a negative pressure generated at the constriction, thereby permitting an evaporative fuel generated in the fuel tank to be introduced into a canister used during refueling. During normal operation which is other than the time of refueling, the negative pressure disappears and hence, the switch-over valve is switched, thereby permitting the evaporative fuel to be introduced into a canister used during normal operation. Thus, it is possible to reliably collect the evaporative fuel generated during refueling into the fuel tank by a simple structure.
