Description

Engine Oil Auto Supply

The present invention relates to a lubrication device for an engine, and more particularly, to an automatic engine oil supply device for maintaining an amount of engine oil stored in an oil pan at all times.

In general, an engine explodes fuel in a combustion chamber consisting of a cylinder, a cylinder head, and a piston, thereby providing linear force to the piston, and the piston is configured to generate rotational force to the crankshaft while linearly reciprocating in the cylinder. .

As described above, the piston reciprocates at a high speed inside the cylinder to generate a rotational force of the crankshaft, and the cylinder has airtightness so that the piston can efficiently convert the energy generated in the combustion chamber into mechanical rotational energy. The piston must be guided while maintaining it.

Therefore, in order to fully perform the above-described role, appropriate engine oil is supplied to each mechanical operating part of the engine including the piston and the cylinder so as to lubricate.

In this case, the engine oil as described above should always be secured in the required amount. Generally, the amount of oil is reduced in automobiles due to leakage of engine oil and combustion due to inflow of engine oil into the combustion chamber. If the engine oil is insufficient to lubricate each part of the engine, the operator must immediately replenish it with sufficient oil.

In particular, if the engine oil stored in the oil pan while the engine is running is not secured enough for the oil pump to inhale, the engine oil cannot be supplied to each mechanical operating part of the engine.

However, if an excessive amount of engine oil is supplied in consideration of the above situation, an excessive amount of engine oil and harmful exhaust gas overrun are caused, so that the oil pan should always be filled with an appropriate amount of engine oil.

However, even when the engine oil is stored in the oil pan in an appropriate amount as described above and consumed by the engine, the engine cannot be replenished while the engine is running.

In addition, since there was no tank for storing engine oil separately from the oil pan, when the engine oil was insufficient in the place where the engine oil was not available, the engine life was inevitably shortened by operating without replenishing it.

Therefore, the present invention has been made to solve the problems described above, and when the engine is running when the engine oil is running out of the automatic supply of the engine oil automatic supply so that the appropriate amount of engine oil is always stored in the oil pan The purpose is to provide.

1 is a view showing an automatic engine oil supply device according to the present invention.

The automatic engine oil supply device according to the present invention for achieving the above object is a reservoir tank for storing the engine oil of the spare portion, and the flow path tube is a passage for the engine oil stored in the reservoir tank flows into the oil pan and And an oil pump mounted to the flow pipe for pumping engine oil of the reservoir tank to an oil pan, a float moving vertically up and down according to the amount of engine oil stored in the oil pan, and detecting the position of the float. To transfer power to the oil pump, the drive pulley connected by the crankshaft and the belt, and when the float falls below the set threshold, remains 'on' and when the engine oil is supplied to the oil pan and the float rises above the set value A relay that remains 'off' and is mounted between the drive pulley and the oil pump so that the relay is 'on' When the state is characterized by configured by comprising a power transmission unit comprising a magnetic clutch for transmitting power of said drive pulley into the oil pump.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 shows an automatic engine oil supply device according to the present invention, a reservoir tank (1) storing spare engine oil and a passage through which engine oil of the reservoir tank (1) flows into an oil pan (2). A flow path pipe 3 to be provided, an oil pump 4 mounted on the flow path pipe 3 to pump engine oil of the reservoir tank 1 to the oil pan 2, and stored in the oil pan 2. It consists of a float 5 moving vertically and vertically in accordance with the amount of engine oil, and a power transmission means for detecting the position of the float 5 to transfer the power of the crankshaft 6 to the oil pump 4.

Here, the power transmission means maintains the 'on' state when the drive pulley 8 connected by the crankshaft 6 and the belt 7 and the kneader 5 are lowered by the first reference value, the engine oil supply level. When the engine oil is supplied to the fan 2 and rises by the second reference value, the relay 9 maintains an 'off' state, and is mounted between the driving pulley 8 and the oil pump 4 so that the relay 9 When the 'on' state is composed of a magnetic clutch 10 for transmitting the power of the drive pulley (8) to the oil pump (4).

Referring to the operation of the present invention configured as described above are as follows.

When the engine oil stored in the oil pan 2 is reduced by the first reference value, which is the engine oil supply level, the float 5 causes the relay 9 to be in an 'ON' state while being lowered by the engine oil.

When the relay 9 is in the 'on' state, the magnetic clutch 10 is driven, and the power of the crankshaft 6 is transferred to the oil pump via the belt 7, the driving pulley 8, and the magnetic clutch 10. It is delivered to (4) to drive the oil pump (4).

The oil pump 4 pumps the excess engine oil stored in the reservoir tank 1 to the oil pan 2, while the engine oil is supplied to the oil pan 2 through the flow path pipe 3. Knit (5) will rise.

When the float 5 rises by the second reference value, the relay 9 is in an 'off' state, and the magnetic clutch 10 stops driving. The power of the crankshaft 6 is driven through the belt 7. The oil pump 4 stops driving because it is transmitted to the pulley 8 so that the drive pulley 8 rotates continuously but the magnetic clutch 10 blocks between the drive pulley 8 and the oil pump 4. The engine oil in the reservoir tank 1 is no longer supplied to the oil pan 2.

As described above, according to the present invention, when the engine oil is insufficient when the engine is running, the engine oil is automatically replenished so that the appropriate amount of engine oil is always stored in the oil pan, and the engine can always maintain the proper lubrication state so that the engine output and durability Can improve the effect.
