る。The operation of the above configuration will be described. When the fuel pump is operated in a state where the first chamber in which the fuel is stored is sealed, the fuel in the first chamber is sucked up and delivered to the engine. For this reason, the internal pressure of the first chamber decreases, and a pressure difference occurs between the internal pressure of the first chamber and the second chamber. Due to this pressure difference, the fuel in the second chamber moves to the first chamber through the siphon tube. After that, the fuel moves from the second chamber to the first chamber until the internal pressures of the chambers are balanced. Therefore, the fuel in each chamber can be sucked up and sent out by the fuel pump communicating with the first chamber.

Even if a drive shaft or the like is located in between, it can be provided by bypassing it. Furthermore, one end of the siphon tube is the second
Since it is communicated with the bottom of the chamber, the fuel in the second chamber can be reliably delivered to the first chamber. As a result, the fuel in the fuel tank can be reliably delivered to the engine by the fuel pump that communicates with the first chamber.

も行えるようにすることができる。Further, the check valve provided in the air passage communicating between the first chamber and the second chamber maintains the internal pressure of the first chamber even if the internal pressure of the second chamber is higher than the internal pressure of the first chamber. . On the contrary, when the internal pressure of the first chamber becomes higher than the internal pressure of the second chamber, the check valve provided in the air passage opens to allow the internal pressure to escape to the second chamber. Therefore, the internal pressure of the first chamber is kept equal to or lower than the internal pressure of the second chamber. Therefore, even if the internal pressure of the first chamber becomes higher than the internal pressure of the second chamber, the internal pressure of the first chamber and the internal pressure of the second chamber are immediately balanced, and the second internal pressure of The fuel can be delivered from the chamber to the first chamber immediately.

The fuel moves from the second chamber 6 to the first chamber 5 until the internal pressure of the first chamber 5 is balanced. When the liquid level in the second chamber 6 becomes higher than that in the first chamber 5, the siphon action of the siphon pipe 21 causes the fuel to move to the first chamber. At this time, the check valve 24 of the air communication pipe 23 is opened to maintain the pressure balance between the chambers 5 and 6. On the other hand, the liquid level of the first chamber 5 is the second chamber 6
The check valve 22 of the siphon tube 21 does not reverse the flow even if the height becomes higher.
