Abstract

(57) [Summary] [Purpose] The object of the present invention is to provide a lubricating oil supply device for an internal combustion engine that can always automatically maintain the amount of oil in a lubricating oil tank at an optimum level. [Structure] A lubricating oil tank 2 attached to the internal combustion engine 1, a lubricating oil replenishing tank 7 arranged under the lubricating oil tank 2,
A refueling pump 8 supplies lubricating oil from the lubricating oil replenishing tank 7 to the lubricating oil tank 2 through an oil supply pipe 9, and its upper end opens at a predetermined height position in the lubricating oil replenishing tank 2, and its lower end opens into the lubricating oil replenishing tank 7. It is characterized by having an overflow pipe 10 that is open.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a lubricating oil supply device for an internal combustion engine.

0002

[Conventional technology]

FIG. 3 is a diagram showing a conventional internal combustion engine lubricating oil supply system. In the figure, 1 is internal combustion Engine, 2 is a lubricating oil tank, 3 is an oil amount regulator, 4 is a lubricating oil supply tank, 5 is a mount, 6 is the oil supply pipe.

0003 When the internal combustion engine 1 starts operating, the lubricating oil that lubricates various parts is consumed. short In the case of hourly operation, it is sufficient to replenish lubricating oil while the engine is stopped, but in the case of long-term operation, Automatic replenishment is required. For this purpose, a tank 4 for replenishing lubricating oil is installed and Replenish through the fuel supply pipe 6. The oil level regulator 3 detects the level of lubricating oil in the lubricating oil tank 2. When the oil level drops, oil is supplied from the lubricating oil supply tank 4. Due to the above natural flow The lubricating oil replenishment tank 4 is placed on a pedestal 5 and placed at a high position to enable refueling. It has been done.

[Problem that the idea aims to solve]

When the internal combustion engine 1 starts operating, lubricating oil is supplied to each part. The lubricating oil level in the lubricating oil tank 2 drops and is replenished from the lubricating oil replenishing tank 4, but When the operation is stopped, the lubricating oil except for the consumed amount returns from the above parts to the lubricating oil tank 2. As a result, the lubricant level in lubricant tank 2 becomes higher than the optimum level, resulting in overfilling. becomes. Therefore, when setting the level of the oil amount regulator 3, it is necessary to consider the return of the lubricating oil. There was a problem in that it took time and effort to set the level.

[0005] This invention was made to solve this problem, and the amount of lubricating oil in the lubricating oil tank We provide a lubricating oil supply system for internal combustion engines that can automatically maintain the optimum amount of lubricating oil at all times. The porpose is to do.

[0006]

[Means to solve the problem]

In order to achieve the above object, the present invention provides a lubricating oil tank attached to the bottom surface of an internal combustion engine. The lubricating oil replenishment tank located below this lubricating oil tank, this lubricating oil replenishing tank A pump that supplies lubricating oil through an oil supply pipe to the above lubricating oil tank, the upper end of which is connected to the above lubricating oil tank. An overcoat that opens at a predetermined height within the tank, and whose lower end opens into the lubricating oil supply tank. - flow tube.

[0007]

[Effect]

In this invention, the internal combustion engine is stopped and lubricating oil is released from each part of the internal combustion engine. Even if the lubricant level in the lubricant tank rises after returning to the oil tank, it will not rise from the optimum level. Flows down through an overflow pipe to a lubricant replenishment tank.

[0008]

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0009] In FIGS. 1 and 2, 7 is a lubricating oil supply tank, which is located below the lubricating oil tank 2. It is arranged. Reference numeral 8 denotes an oil supply pump, which pumps lubricating oil from the lubricating oil supply tank 7. The lubricating oil is supplied to the lubricating oil tank 2 through the raised oil supply pipe 9. 10 is the overflow pipe. The above end opens at a predetermined height position of the lubricating oil tank 2, and the lower end opens at a predetermined height position of the lubricating oil tank 7. It is open inward.

0010 In this embodiment, when the internal combustion engine 1 is stopped, lubricating oil is supplied from each part of the internal combustion engine 1. Even if the lubricant returns to the lubricant tank 2 and the lubricant level in the lubricant tank 2 rises, it will not reach the optimum level. (The height of the upper end of the overflow pipe 10) 0 and flows down to the lubricating oil supply tank 7.

[0011] The oil supply pump 8 may be operated intermittently at predetermined time intervals, and the lubricating oil level in the lubricating oil tank 2 may be A detector is installed to detect the bell, and the operation is controlled by the output signal of the detector. You may.

0012 Also, when replacing the lubricating oil in the lubricating oil tank 2 with a new one, the oil supply pump 8 should be turned in the opposite direction. The lubricating oil in the lubricating oil tank 2 is supplied with the lubricating oil by the lubricating pump 8. Transfer the lubricating oil to the replenishment tank 7, then pull out the lubricant replenishment tank 7 and drain the lubricant. can be disposed of.

[0013]

[Effect of the idea]

As explained above, the present invention arranges the lubricating oil tank and the lubricating oil supply tank in a vertical relationship. Since the two are connected via an overflow pipe, the oil level in the lubricating oil tank can be constantly monitored. The optimal level can be maintained automatically.
