摘要： A fuel cut-off valve 100 of the invention is attached to an upper portion of a fuel tank and connects and disconnects inside with and from outside of the fuel tank according to the fuel level in the fuel tank. In the fuel cut-off valve 100 of the invention, a valve casing 110 forms a first valve chest 120 and a second valve chest 130 connected to the fuel tank and has an inter-valve chest flow passage 112 connecting the first valve chest 120 to the second valve chest 130 and a canister connection port 102 connecting the second valve chest 120 to a canister placed outside the fuel tank. A first float 124 and a second float 134 are respectively located in the first valve chest 120 and in the second valve chest 130. When the fuel level in the fuel tank rises to reach a preset first level FL1, the first float 124 moves up to close an opening 122 and thereby close the inter-valve chest flow passage 112. When the fuel level in the fuel tank further rises to reach a preset second level FL2 that is higher than the preset first level FL1, the second float 134 moves up to close an upstream end opening 132 of the canister connection port 102 and cut off the flow of fuel vapor to the canister. This arrangement of the invention effectively ensures the sufficient performances and the enhanced reliabilities of the leakage protection function and the backflow prevention function of the fuel cut-off valve.

摘要： A fuel tank valve device equipped with a casing, and a valve mechanism. The valve mechanism has a first valve unit having a first valve connecting hole, and a second valve unit that opens and closes the first valve connecting hole. The first valve unit completely closes the valve flow path by moving by the force in the valve closing direction when the pressure of the second communication path exceeds a preset first pressure value. In a state when the first valve unit is closing the valve flow path, when the pressure of the second communication path exceeds a preset second pressure value that is greater than the first pressure value, the second valve unit receives the pressure from the first valve connecting hole and moves to open the first valve connecting hole, communicating with the valve flow path.

摘要： A fuel valve comprises a first valve chamber and a second valve chamber within a casing, where a first valve mechanism and a second valve mechanism are housed in the respective valve chambers. A first float of the first valve mechanism rises when the fuel level reaches a first liquid level, to close a first connection conduit. The second valve mechanism rises to close a second connection conduit when a second liquid level, which is higher than the first liquid level is reached. A valve conduit, which acts as a restriction path, is provided between the first valve chamber and the second valve chamber. The valve conduit is formed with a conduit area that is less than that of the first connection conduit, so as to increase the pressure within the fuel tank when the first connection conduit is closed.

摘要： A fuel cap is provided to improve sealing characteristics of a pressurized fuel tank. When the inner pressure P of a fuel tank is a negative pressure less than a predetermined regulation negative pressure Pr which does not need to be controlled, a valve 160 is pressed upward by the urging force of a spring 164 to bring a lip portion 161 of the valve 160 into contact with a seal surface 156 of a seal body 150 to thereby close the valve 160. As a result, the fuel tank is sealed from the outside air. At this time, a flat plate portion 155 of the rubber-made seal body 150 is bent by the urging force of the spring 164 so that the gap L between the flat plate portion 155 and the lower surface of a ceiling plate portion 131 is narrowed. In addition, the divergence of center of the valve 160 with respect to the seal body 50 is limited by ribs 162 of the valve 160 located in a valve slide hole 135.
