Reference numeral 16 is a tubular metal fitting mounted on the valve cap 12 so as to cover the oil supply hole 12a, 16a and 16b are a plurality of oil circulation holes provided in the peripheral wall of the tubular metal fitting 16, and 16c is the same tubular metal fitting 16 16d protruding inward in the axial direction of the peripheral wall of the
Is a partition part of the tubular metal fitting 16 that divides each oil circulation hole provided in the peripheral wall of the tubular metal fitting 16 into two parts, and the oil circulation holes 16a and 16b are divided by the partition portion 16d into the upper oil circulation hole 16a and the lower oil circulation hole 16a. It is divided into two oil circulation holes 16b. Upper oil circulation hole 16a
Is at a position corresponding to the oil discharge port 14a at the tip of the oil supply pipe 14 of the oil supply pump 13. In addition, 16e is an air vent hole provided in the upper part of the tubular fitting 16, and 14b is an oil level detection sensor provided at the tip 14c of the oil supply pipe 14 of the oil supply pump 13.

When refilling the kerosene to the cartridge tank body 11 configured as described above, the cartridge tank body 11 removed from the oil burning equipment is placed with the valve cap 12 on top, and the tip end of the oil supply pipe 14 of the oil supply pump 13 is placed. While pressing the valve body 15 against the spring 17 with 14c, insert the oil supply pipe 14 into the inside of the tubular metal fitting 16 from the oil supply hole 12a of the valved cap 12,
The tip 18a of the holder 18 is connected to the lower end annular portion 12b of the valve cap 12.
The holder 18 is held by the valve-equipped cap 12 by being hooked on. In this state, the restoring force of the spring 17 causes the oil supply pipe 14
Although a pushing force acts on the valve body 15 through the valve body 15, the refueling pipe 14 is held by the valve cap 12 by the engagement between the lower end annular portion 12b of the valve cap 12 and the tip portion 18a of the holder 18 described above. .

By operating the refueling pump 13 in this state, kerosene is pumped up from a kerosene tank (not shown) as indicated by a dashed arrow A, and the refueling pipe 14, the oil discharge port 14a, and the oil discharge port 1 are discharged.
Kerosene is replenished into the cartridge tank body 11 through an oil circulation hole 16a provided at a position corresponding to 4a as shown by an arrow B.

Can be pulled out to the outside of the valve cap 12, and the cartridge tank body 11 can be attached to the oil combustion equipment.

In this way, the cartridge tank main body 11 can be refueled without touching the valved cap 4 at all, so that the hands will not be contaminated with kerosene and the unpleasant feeling of refueling can be experienced as in the past. There is no.

Further, as shown in FIG. 1, the oil supply pipe 14 of the oil supply pump 13
Since the valve fitting cap 12 is inserted into the valve fitting cap 12, the tubular fitting 16 of the valve fitting cap 12 is considerably long, and the strength of the tubular fitting 16 is reduced because the oil circulation hole 16a is provided. Since the cylindrical metal fitting 16 of the cartridge tank is provided with a plurality of ridges 16c protruding inward on the peripheral wall and the partition portion 16d, its strength is maintained sufficiently.

Further, since the protrusion 16c on the peripheral wall of the tubular metal fitting 16 reduces the contact surface with the valve body 15, the tubular metal fitting 16 is long and the oil outlet holes 16a and 16b are plural, but the valve body 15 has a small gap. The movement will be smooth. Further, since the valve shaft 15a of the valve element 15 penetrates the bottom of the tubular metal fitting 16, the valve element 15 is
The valve 15 is supported at two places, that is, the contact portion B between the ridge 16c and the ridge 16c, the movement of the valve body 15 is smooth, and the oil supply hole 12a is accurately closed.

On the other hand, the oil circulation holes 16a and 16b in the peripheral wall of the tubular metal fitting 16 are configured such that when both of these oil circulation holes are continuous, the oil supply pump 13
There is a possibility that kerosene will fill the periphery of the oil level sensor 14b and malfunction may occur, but since both oil circulation holes are divided into upper and lower parts, kerosene during refueling will form a shade from the upper oil circulation hole 16a. The oil does not spread and the kerosene does not fill the periphery of the oil level sensor 14b, and the malfunction does not occur.

As described above, according to the present invention, the kerosene can be directly replenished by inserting the refueling pipe of the refueling pump into the cap refueling hole of the cartridge tank without removing the cap from the cartridge tank body, and the hands can be soiled. Can be refueled without. Further, since the tubular metal fitting of the valve cap is provided with an inwardly projecting ridge and the valve body is provided with a valve shaft penetrating the bottom of the tubular metal fitting, the tubular metal fitting is long even though it is long. The strength is maintained to be sufficient, and the movement of the valve body is smooth, which makes it highly practical even when used for a long period of time.
