The oil of No. 7 flows into the right oil pan 35 through the electromagnetic pump 41 and the oil feed pipe 42. Here, the electromagnetic pump 41 has about 30
It is energized only for a predetermined time of ~ 60 seconds,
1 and the passage in the oil feed pipe 42 are filled with oil, and the oil continues to flow in the electromagnetic pump 41 and the oil feed pipe 42 due to the siphon phenomenon. This oil stops flowing when the oil level of the right oil pan 35 reaches the same level as the oil level of the left oil pan 37, and the oil in the right oil pan 35 is consumed, and the oil in this right oil pan 35 is consumed. When the surface becomes lower than the oil level of the left oil pan 37, the flow starts again. Thus, the left refueling tank 38
The oil in the left oil receiving tray 37 can be transferred to the right oil receiving tray 35 by utilizing the siphon phenomenon that occurs in the electromagnetic pump 41 and the oil feed pipe 42 until is empty.

Has a structure without a check valve, as shown in FIG.
It is not necessary to provide components such as a check valve and a valve seat for a check valve, and the structure can be simplified and the price can be reduced accordingly, and the cost can be reduced.

ができる。Further, the oil feed pipe 42 raises one end portion 42A connected to the oil transfer electromagnetic pump 41 to a position higher than the electromagnetic pump 41, and the intermediate portion 42B at the steady oil level L1 of the left oil pan 37. The position is lower than the corresponding position and extends substantially horizontally toward the right oil pan 35, and the other end 42C is lower than the one end 42A and the right oil pan 3
After starting up higher than 5, since it is exposed to the right oil pan 35 and is constantly immersed below the oil surface of the right oil pan 35, a siphon phenomenon occurs in the electromagnetic pump 41 and the oil feed pipe 42, and the electromagnetic pump Even after the driving of 41 is stopped, the oil in the left oil pan 37 can be transferred to the right oil pan 35 by utilizing the siphon phenomenon, so that the energization time to the electromagnetic pump 41 can be extremely shortened and the power consumption of the electromagnetic pump 41 can be reduced. It can be significantly reduced.

ポンプ41を制御する必要がない。Furthermore, since the oil in the left oil pan 37 is transferred to the right oil pan 35 by utilizing the siphon phenomenon occurring in the electromagnetic pump 41 and the oil supply pipe 42, a large amount of oil is fed from the electromagnetic pump 41 to the oil from the right oil pan 35. Does not need to be controlled, and there is no need to control the electromagnetic pump 41 using a complicated safety control device as in the conventional case.

うなことも防止でき、安全性が向上する。Furthermore, the oil in the refueling tank 38 has one of the oils due to an increase in the internal pressure of the refueling tank 38 (for example, when the oil is left outdoors in a low temperature and left in a high temperature room). Even if the oil is excessively pushed out to the pan 37, the siphon phenomenon occurring in the electromagnetic pump 41 and the oil feed pipe 42 always causes the oil to flow to the other pan 35, so that only the oil surface of one pan 37 rises abnormally. Oil can be prevented from overflowing and safety is improved.

構成を簡素化できる。As described above, according to the present invention, an inexpensive pump having a simplified structure can be used as a pump for transferring the oil in the second oil receiving tray to the first oil receiving tray, and the cost can be reduced. Of course, since the oil in the second oil pan can be transferred to the first oil pan by using the siphon phenomenon that occurs in the pump and the oil feed pipe, the time for energizing the pump is shortened and the power consumption of the pump is reduced. , Running cost is reduced. In addition, since the oil in the second oil pan can be transferred to the first oil pan by utilizing the siphon phenomenon, there is no risk of oil leakage due to a large amount of oil sent by the pump, and a structure for maintaining safety Can be simplified.
