Abstract

PURPOSE:To ensure normal operation of a non-return valve and prevent liquid leakage from the non-return valve by providing a non-return valve arranging chamber above a liquid accommodating section in a tank and providing a fluid splash preventing board between the non-return valve arranging chamber and the liquid accommodating section. CONSTITUTION:In a lubricating or fuel oil tank for marine propulsion machinery, a splash preventing board 50 is installed between a non-return valve arranging chamber 46 and a liquid accommodating section 47. With this, even oil in a subtank 25 for an outboard motor 10 is oscillated and ruffled while the boat is sailing, splashes scattered toward the non-return valves 48 and 49 sides are prevented from reaching the non-return valves 48 and 49 because they are interruped by the splash preventing board 50. Accordingly, since no oil sticks to the operation section of the non-return valves 48 and 49, pressure in the subtank 25 is constantly kept at the atmospheric pressure during the operation of a suck- up pump. Thus, the back pressure at the outlet port of the suck-up pump is kept nearly constant, thereby stabilizing sucking operation of the pump.

] 1. As the lubricating oil is consumed, the oil level in the sub-tank 25 falls from the full oil level 34A and reaches the replenishing oil level 34B, the float 41 also drops and the magnetic ring 43 turns on the lead switch-42B. Then, the pump 22 is driven via the electric circuit in the control box 44, and the lubricating oil in the main tank 21 is pumped into the sub tank 25. "Kumu"-
The flow rate of the lubricating oil pumped up by the pump 22 is set to be larger than the maximum amount of lubricating oil consumed by the engine 16, and therefore the oil level in the sub-tank 25 rises to reach the full oil level 34A. At this time, the float 41 also rises in response to the rise in the oil level, and the reed switch edge 42A is turned ON by the magnetic ring 43, and the motor of the pump 22 is stopped, and the lubricating oil is pumped up. Stop. Normally, by repeating the above-mentioned pumping operation, one lubricant mountain in the sub-tank 25 is filled with oil level 34A and supply oil level 34.
It is said to be maintained at the gate with B.

In FIG. 5(C), a communication passage 63 is provided between the scattering gap 11 and the periphery of the plate 62, and its central part is convex with respect to the reverse 1)-valve arrangement chamber 46, and with respect to the liquid storage part 47. It has a concave shape. This scattering prevention plate 62 makes it difficult for the lubricating oil scattered from the liquid storage part 47 to enter the check valve arrangement chamber 46, and prevents the lubricant oil that has entered the check valve arrangement chamber 46 from entering the liquid storage part 47.
Makes it easy to discharge.

Note that the embodiment 1-1 is based on the propulsion unit 1-1 of the outboard motor 10.
The case where the present invention is applied to the sub-tank 25 disposed in the tank 5 has been described. However, the present invention may be applied to the fuel tank 20, main tank 21, etc. in the embodiment described below, and is also widely applicable to tanks other than those for marine propulsion machines.

As described above, the tank according to the present invention is provided with an inverted 11-valve arrangement chamber above the liquid storage part in the tank, and a liquid scattering space between the inverted 11-valve arrangement chamber and the liquid storage part. A 1F board is provided. Therefore, even if the liquid in the tank oscillates and ripples, the liquid's reverse 1! −
The droplets heading towards the square are blocked by the scattering plate 11 and do not reach the check valve, ensuring normal operation of the reverse 11 valve and preventing liquid leakage from the reverse 11 valve. It becomes possible to do so.
