タポンプを備えたものが知られている。Conventional Technology Some automobile fuel tanks have an inward bulge formed on the bottom wall of the tank body due to the structure of the part on which the fuel tank is mounted. Some methods are designed to avoid interference between the bottom wall and the functional parts of the car body, but by forming a bulge like this,
If the lower half of the tank body is divided into two main and sub compartments, fuel will remain in one of these compartments, so the pressure of the fuel returned from the engine's fuel supply system can be used effectively. There is a known fuel tank equipped with an ejector pump that sucks fuel in the auxiliary chamber and transfers the liquid into the main chamber.

に示されている。Figures 2 and 3 show a vehicle fuel tank equipped with such an ejector pump, where l is the tank body, and a bulge 2 is formed inward at approximately the center of the seat. can be,
A main chamber 3 and a sub-chamber 4 are separated from each other in substantially the lower half of the tank body 1. A feed pump 5 is disposed inside the main chamber 3, and when the foot pump 5 is driven, fuel is filtered from inside the main chamber 3 by a filter 6, and is passed through a feed pipe 7 to the fuel (not shown). It is adapted to be fed to a feeding device. Reference numeral 8 denotes a guide pipe that is disposed protrudingly within the tank body 1 and returns surplus fuel that is not consumed by the fuel supply device into the tank body 1. A nozzle 9 is formed at the end of the guide pipe 8, and a chamber 10 is formed by enclosing the nozzle 9.
A constricted part 11 is formed below, and a throat part 12 is formed following the constricted part 1. The chamber]0 has a filter 1
5 is connected to a suction pipe 14 disposed near the bottom of the auxiliary chamber 4, and the nozzle 9 is connected to the constriction part 1.
By spouting the return fuel towards the chamber IO
The ejector pump 15 generates a negative pressure inside the chamber IO, sucks the fuel in the auxiliary chamber 4 into the chamber IO, and transfers the fuel together with the returned fuel into the main chamber 3 through the throat section 12. This similar structure is shown in, for example, Japanese Utility Model Application Publication No. 1-83162.

料タンクの燃料吸込装置を提供するものである。Problems to be Solved by the Invention If the return fuel is spouted in a spot from the nozzle 9 when the ejector pump 15 is started, the ejector pump 15 The briming performance, that is, the initial characteristics of fuel suction and liquid transfer from the auxiliary chamber 4 to the main chamber 3 will deteriorate. For this reason, the nozzle 9 in the guide pipe 8 as shown in FIG.
A swirler 16 is installed directly above the nozzle 9 to give a swirling flow to the fuel sent to the nozzle 9, and the return fuel is spouted from the nozzle 9 in a cone shape, thereby closing the throat portion 12 side of the chamber 10. The rise of the negative pressure within the IO is accelerated, and the initial characteristics of sucking up fuel from the auxiliary chamber 4 are improved. However, if the swirler 16 is installed inside the induction pipe 8 in this way, not only will the number of parts and the number of assembly steps increase, resulting in an increase in cost, but the swirler 16 will act as a flow resistance and the guide pipe 8 This causes an increase in internal pressure, which has a considerable influence on the pressure on the fuel supply system. In addition, it is also possible to vent the throat part 12 in a three-shape shape midway through it to form a liquid pool, thereby blocking the outlet of the chamber 10 with the remaining liquid and hoping for negative pressure to be generated. On the contrary, this would impede smooth fuel transfer, and would not be the best solution since it would increase the size of the pump. Therefore, the present invention prevents the internal pressure of the guide pipe from increasing,
The present invention provides a fuel suction device for a fuel tank that can improve the briming characteristics of an ejector pump without increasing the size of the ejector pump.

Close the part side. As a result, suction of air from the throat part following the constriction part is prevented, the rise of negative pressure in the chamber is accelerated, and the fuel from the sub-chamber side is sucked into the chamber from the suction vibe, and the nozzle The flow velocity is increased by the throttle part together with the jet flow from the fuel and the fuel flowing out from the branch flow path, and the fuel is discharged from the throat part toward the main chamber.

When started, the return fuel flowing through the guide pipe 8 is vigorously jetted out from the nozzle 9 toward the constriction part 11 in a spot shape, while a part of the return fuel upstream of the nozzle 9 passes through the branch flow path 17. It flows out to the vicinity of the constriction part 11 of the chamber 10. As a result, the throat portion 12 side of the chamber 10 is sealed (occluded) by the fuel flowing out from this branch flow path 17, thereby preventing air from being sucked in from the throat portion 12 following the constriction portion 11, and the chamber The build-up of the negative pressure in the chamber 10 is accelerated, and the fuel in the auxiliary chamber 4 is quickly sucked into the chamber IO from the suction pipe 14. The fuel sucked into the chamber 10 in this manner, together with the jet from the nozzle 9 and the fuel flowing out from the branch passage 17, reaches the constriction part 11, where the flow velocity is increased, and is discharged from the throat part 12 toward the main chamber 4. be done.
