Reference numeral 31 is an exhaust passage, and 32 is an exhaust outlet provided at an inlet portion of the storage tank 22. At this time, the fuel filler port 9 is completely sealed by the airtight packing 3b, and therefore has the same volume as the supplied kerosene. Air passes through the exhaust passage 31 and exits from the exhaust outlet 32.

Reference numeral 33 denotes an exhaust inlet, and when the exhaust inlet 33 is set at a position in the tank 1 where kerosene to be fed is flowing out, the fed kerosene again passes through the exhaust passage 31 and returns to the suction side pump main body 21. That is, a short circuit phenomenon occurs, and the efficiency becomes extremely poor at the oiling speed. In order to maximize the oiling speed, it is necessary to have a structure that does not cause this short circuit phenomenon. Three

FIG. 5 is a sectional view showing the shape of spilled kerosene in the case where there is a short circuit prevention tray. In the figure, kerosene flows through the oil supply passage 30 of the lubrication device and flows into the tank 1 from the refueling cap 2. However, since there is the short circuit prevention tray 34, there is no spilled kerosene near the exhaust inlet 33 of the lubrication device. Only the exhaust air passes through the suction side pump main body 21 of FIG. 4 and enters the storage tank 22. The diameter required for the short circuit prevention tray varies depending on the kerosene filling speed, but by appropriately changing the diameter and depth, the short circuit phenomenon can be completely prevented.

Further, when the oil supply is continued, kerosene accumulates in the tank 1, and when the oil level rises to the height of the exhaust inlet 33, the kerosene enters the exhaust passage 31 and is sent to the exhaust outlet 32. Therefore, even if oil is further injected, since the tank 1 is completely shielded from the outside air by the airtight packing 3b, kerosene is not injected above the height of the exhaust inlet 33.

〔The invention's effect〕

As described above, when the holder body is restrained by the restraining means to the oil supply cap, the oil-lubricating device of the present invention uses the airtight means to connect the holder body and the oil supply cap to the oil supply passage and the exhaust passage. Is completely cut off from the outside air,
After the oil is filled to the height of the exhaust port of the cartridge tank, the kerosene in the cartridge tank is sent to the storage tank through the exhaust passage and returns to the storage tank.Therefore, inadvertently continue to fill the cartridge tank with oil. Also, kerosene does not spill outside, and even if the cartridge tank is accidentally collapsed during lubrication, kerosene does not spill outside, and it is possible to reliably lubricate the cartridge tank.
