Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubricating device for lubricating various parts of an engine, and more particularly to a lubricating device for an engine in a pressure type lubrication system in which a start switch of the engine is turned on to perform lubrication. It is a thing.

[0002]

2. Description of the Related Art Engine lubrication has an important purpose of reducing frictional resistance and preventing wear of various parts of the engine, and has other purposes such as cooling and soundproofing. Lubrication is carried out over the details such as the bearing surface and each sliding surface that are configured in the engine.Crank bearings, connecting rod bearings, cam bearings, piston pins are important parts where lubrication is required. , Timing gears, chains, arms, cam followers, cylinders, etc.

Further, there are a pressure type, a scatter type, a gravity type, and a composite type in which these are appropriately combined as an oil supply system for supplying oil to each of the above-mentioned parts. Is forcibly pumped to lubricate each part of the engine, it has an excellent lubricating effect and is widely used in automobiles and large engines. Therefore, the conventional lubrication method is shown in FIG.
According to the explanation, the pressure of the oil pumped by the pump 2 from the oil tank 1 in the lower part of the crank chamber is adjusted by the adjusting valve 3 and cleaned by the oil filter 4,
After lubricating each part of the engine 7 through the check valve 5 and the main oil supply pipe 6, the system returns to the oil tank 1 again.

[0004]

In such a conventional lubrication system, the pump 2 for pumping oil is driven by a gear such as a crank shaft or a cam shaft, a chain, or the like. In the initial stage of driving, that is, in the initial stage of starting, the engine is driven for a certain time without lubrication of each part of the engine. Therefore, among the factors of wear of various parts of the engine, there is a defect that the amount of wear is large at the initial stage of starting without lubrication. So, at the beginning of engine operation,
The technical problems to be solved in order to lubricate the various parts of the engine even in the initial stage of starting arise, and the object of the present invention is to solve the problems.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in order to achieve the above-mentioned object, in which oil pumped from an oil tank is supplied with a regulating valve, an oil filter, a check valve, and an oil main supply pipe. In a lubricating device for an engine formed to be lubricated to various parts of the engine, the oil main supply pipe is connected to an accumulator as a connecting pipe, and the connecting pipe is provided with a check valve and the check valve. An electronic switching valve that is operated by operating a start switch is installed between the front and rear connecting pipes, and while the engine is operating, the accumulator is filled with oil through the check valve, and the start switch is turned on and the accumulator is turned on. The oil filled in the engine is transmitted to each part of the engine through the electronic switching valve and lubricated. There is provided a lubricating device.

[0006]

Since the present invention is configured as described above, the oil filled in the accumulator during operation of the engine turns on the start switch and is transmitted to each part of the engine to lubricate each part of the engine at the initial stage of starting. By doing so, it is possible to prevent wear in the initial stage of starting and significantly extend the life of the engine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an engine lubricating device of the present invention will be described below with reference to the drawings. 1 and 2 are system diagrams of a lubricating device of the present invention. In the technical configuration of the present invention, the oil pressure-fed by the pump 2 from the oil tank 1 is lubricated to each part of the engine 7 through the oil filter 4, the check valve 5, and the oil main supply pipe 6 as in the conventional technical configuration. Although the same, the present invention is different only in that the starting switch 11 is set to the ON position and lubrication is performed. Only the configuration will be described.

An accumulator 8 is connected to the main oil supply pipe 6 by a connecting pipe L. A check valve 9 is installed in the connecting pipe L, and between the connecting pipe L before and after the check valve 9. An electronic switching valve 10 is provided. The accumulator 8 can be any known gas type, spring type, or tube type,
The check valve 9 is connected so as to allow only the flow to the accumulator 8 side, and the electronic switching valve 10 is connected to the start switch 11 of the engine, and is opened when the start switch 11 is in the ON position. Has become.
Incidentally, reference numeral F in the figure indicates an intake filter.

Next, a description will be given of a state in which each portion of the engine is lubricated at the initial stage of starting by the lubrication apparatus according to the embodiment of the present invention described above. When the pump 2 is operated by driving the engine, the oil in the oil tank 1 is supplied to each part of the engine 7 through the oil filter 4, the check valve 5 and the oil main supply pipe. At this time, the oil passing through the oil main supply pipe 6 is supplied. Is filled in the accumulator 8 through the connecting pipe L and the check valve 9. The oil thus filled in the accumulator 8 is not backflowed due to the closed state of the check valve 9 and the electronic switching valve 10, and the accumulator 8 It will be in the state of being filled. After the engine 7 is stopped in such a state, when the start switch 11 is turned to the on position as shown in FIG. 2 to drive the engine 7, the electronic switching valve 10 is opened and the accumulator 8 is filled. Oil is temporarily supplied to each part of the engine 7 through the electronic switching valve 10, the connecting pipe L, and the oil main supply pipe 6, and after the lubrication is performed in the initial stage of operation, the pump 2 is further operated to further accumulator 8. The oil is charged inside through the main oil supply pipe 6, the connecting pipe L and the check valve 9.

Therefore, every time the start switch 11 is turned to the ON position to drive the engine 7, the parts of the engine 7 are lubricated at the beginning of the operation of the engine 7, so that the wear at the initial start can be prevented. is there. In the embodiment of the present invention as described above, the pressure type lubrication system is used in combination with the present invention. However, the engine lubrication system of the present invention is used in combination with any lubrication system. It is possible.

[0011]

According to the lubrication apparatus of the present invention as described above, the start switch is turned on and oil is supplied to each part of the engine, so that the current state of wear in the initial stage of start is significantly reduced and the engine is aged. There is an effect that can be prevented.
