    摘要: In an evaporative fuel processing device, an evaporative fuel passage communicating at one end to an upper space in a fuel tank is connected at the other end to a refueling line at a location corresponding to a negative pressure introducing hole provided in a lower portion of a tip end of a nozzle during refueling by a refueling nozzle which is constructed so that the refueling by the refueling nozzle is automatically stopped in response to a fuel liquid level reaching the negative pressure introducing hole during refueling. The draft resistance of an evaporative fuel passage interconnecting an inlet of the refueling line and a tank body is set larger than the draft resistance of an evaporative fuel passage interconnecting the tank body and a canister. Thus, the releasing of evaporative fuel from the fuel tank during refueling is effectively inhibited without use of a potentially unreliable seal.

    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: An evaporative fuel-processing system for an internal combustion engine for use in a vehicle. A passage extends between the fuel tank and the intake passage, for guiding evaporative fuel generated in the fuel tank, for processing, across which a canister is arranged. A first passage and a second passage are connected to the canister. A first valve is arranged across the first passage to allow air to flow into the canister through the first passage and inhibit air containing evaporative fuel from being discharged from the canister through the first passage. A second valve is arranged across the second passage to inhibit air from flowing into the canister through the second passage and allow air containing evaporative fuel to be discharged from the canister through the second passage. A filter is arranged in the first passage.

    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: A canister includes a partition wall which extends toward the lid member with one end thereof connected to the end wall and opposite sides are connected to an inner surface of the casing body. First and second adsorbent layers, formed by an adsorbent, are retained between first and second filters and a third filter, respectively. The first and second filters are fixedly disposed on opposite sides of the partition wall to define first and second chambers between the first and second filters and the end wall, respectively. The third filter is placed and carried on an inner surface of a support plate which is fitted in the casing body and which has a large number of communication bores. The support plate and a lid member are biased by a spring in a direction to compress the first and second adsorbent layers. An inclination inhibiting portion is provided on at least one of the casing body and the partition wall on the opposite side from the third chamber with respect to the third filter and the support plate at a distance from the third filter which substantially corresponds to a distance between the third filter and the partition wall. Thus, it is possible to prevent a reduction in adsorbing efficiency by preventing the third filter and support plate from inclining.

    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: 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.
