    摘要: A device includes a housing fixed to an upper wall of a fuel tank, and having a communication opening in communication with a canister, a float valve received within the housing and floating on a fuel, and the float valve moving upward and downward so as to close and open the communication opening, and a tubular member communicating with the housing, and extending downwardly from the housing into the interior of the fuel tank. The device has through holes of a small diameter which are disposed near an upper wall of the fuel tank, and when the liquid level of the fuel in the fuel tank reaches the lower end opening of the tubular member, a pressure within the fuel tank increases, whereby the filling-up of the fuel tank is detected. When the liquid level of the fuel abnormally rises, the float valve closes the communication opening.

    摘要: In an evaporative-fuel emission preventing apparatus, a differential pressure regulating valve provided in the course of a passageway for connecting a fuel tank and a canister includes a valve section and a case section including a conduit for connecting the differential pressure regulating valve and the canister. The valve section has a communicating hole for connecting the low and high pressure sections of the differential pressure regulating valve. Liquid fuel flowing into the low pressure section is returned to the fuel tank via the communicating hole. When fueling, the quantity of air in the communicating hole can be controlled by a convex portion. Further, the conduit has a communicating hole for connecting the conduit and the fuel tank. When an interlocking valve formed in the valve section moves with an opening operation of the valve section and is separated from the communicating hole, liquid fuel within the conduit can be returned to the fuel tank via the communicating hole. Further, a gas-liquid separating member is formed integrally with the valve section. Even when the differential pressure regulating valve inadvertently opens due to running vibration of the vehicle or the like, an opening portion of the differential pressure regulating valve is closed by the gas-liquid separating member, which makes it possible to prevent the liquid fuel from being introduced into the canister.

    摘要: A fuel vapor control apparatus halts deterioration in operating characteristics of a fuel control valve at the time of fuel supply and prevents fuel vapor from being discharged into the atmosphere through a filler pipe. The fuel vapor control apparatus prohibits fuel vapor from flowing toward a filler pipe by closing a fuel drop passage at the time of fuel supply. A fuel vapor control valve is configured as a diaphragm valve made of a flexible material, and a diaphragm holder moving integrally with the diaphragm valve is provided at the center thereof. Furthermore, the fuel drop passage as a communication hole is formed in the diaphragm portion at a location radially outward of the diaphragm holder, which is provided with an umbrella portion for opening and closing the fuel drop passage.

    摘要: Inside of a first absorption chamber of a canister, a heat storage material container in which a heat storage material constituted of a material that is larger in thermal conductivity and higher in heat capacity than an absorber is accommodated is provided. Since the heat storage material is isolated from the absorber, a larger contact area of the absorber with vaporized fuel gas and air can be secured, and thereby the absorption capacity and desorption capacity of the absorber can be highly exerted. Accordingly, the heat storage material can inhibit the absorber from varying in temperature, the absorber can be prevented from deteriorating in absorption capacity, and the heat storage material can be prevented from deteriorating.

    摘要: In a hollow resin container, at a connecting portion between a separator and a resin layer, through-holes, each of which has a surface which is coplanar with and continuous with an inner side surface of the hollow resin container and whose axial direction cross-sectional configuration is triangular, are formed at a base portion of the separator. The surfaces of bottom portions of the through-holes, which surfaces are coplanar with and continuous with the inner side surface of the hollow resin container, are covered with the gas barrier sheet. Namely, a cross-sectional area S of the separator at the connecting portion in a plane which is coplanar with the inner side surface of the hollow resin container is smaller than a cross-sectional area S4 of the separator in a plane parallel to the aforementioned plane and at a region at which the through-holes are not formed (S4>S). As a result, at the connecting portion between the separator and the resin layer, a region at which the gas barrier sheet does not exist is made small. Therefore, sealability at the connecting portion can improve.

    摘要: A fuel tank body has a double-layer structure composed of an inner tank shell and an outer tank shell, so that an inter-tank-shell space is formed therebetween. Because heat of fuel in the fuel tank body is discharged into the inter-tank-shell space, the temperature of fuel in the fuel tank body is prevented from rising. If the pressure in a canister becomes negative due to a negative pressure in an intake system of an engine, more specifically, a negative pressure in a surge tank leading to an air cleaner, high-temperature air in the inter-tank-shell space between the inner tank shell and the outer tank shell flows into the canister. On the other hand, low-temperature air flows from the air cleaner into the inter-tank-shell space which has become negative in pressure.

    摘要: A fuel evaporative-gas emission preventing apparatus capable of reducing the quantity of adsorption of a canister as low as possible by a single breather at any fueling speeds and allowing emissions to fall within given limits. One end of the breather is coupled to a portion near a port of an inlet pipe for a fuel tank and a differential pressure regulating valve is connected to the other end of the breather. The canister is coupled to the differential pressure regulating valve. An opening-area variable device is provided at an intermediate portion of the breather and adjusts the quantity of a fuel evaporative-gas in the breather according to an internal pressure of the fuel tank.

    摘要: A cooling unit is mounted to an upper wall of a fuel tank so as to cool fuel. A control valve and a vent valve are disposed in a vapor line extending from a float valve to a canister. The control valve and the vent valve are disposed in parallel with one another and constitute a valve member. A cooling unit is mounted to an evaporation passage between a float valve and the valve member. Operation of the cooling units serves to cool fuel and inhibit generation of vapor. If the pressure in the fuel tank exceeds a control pressure, a control circuit opens the control valve and performs control such that the pressure in the fuel tank becomes lower than a running-state relief pressure.

    摘要: In a hollow resin container, a seal portion is formed substantially at as center of a portion at which an inlet hose and a part attachment portion of a resin layer are overlapped. A gas barrier sheet extends to a region further toward an outer side of the hollow resin container than the seal portion. Accordingly, there is no region of the inner side surface of the part attachment portion which is not covered by the gas barrier sheet. Thus, sealability at the part attachment portion, which serves as a portion for attaching the inlet hose, can improve.
