Abstract

PURPOSE: A lubricating oil supply apparatus is provided to prevent damage on an engine due to wear of the engine and burning of a bearing by automatically supplying sufficient oil from an oil tank depending on the level of oil in an oil pan. CONSTITUTION: A lubricating oil supply apparatus comprises: a float(2), a float chamber switch(3) controlling upper and lower limits of oil level in an oil pan(1); a solenoid valve(7) opening and shutting off an oil supply conduit(9) by turning on/off of the chamber switch; an oil reservoir tank(8) supplying oil to the oil pan via the oil supply conduit; and an ECU(Electronic Control Unit)(10) controlling the solenoid valve for rushing into an operational state after specific time from when an ignition key of an engine is turned off. If a mobile body(6) of the float contacts with a lower terminal(5) of the chamber switch due to descending of the float, the solenoid valve supplies oil in the oil tank by opening the conduit. If the oil level in the oil pan rises, the mobile body contacts with an upper terminal(4) for shutting off the conduit. As oil is automatically supplemented depending on the oil level in the oil pan, damage on an engine is avoided.

[Industrial use]

The present invention relates to a lubricating oil supply apparatus for an engine provided with an auxiliary tank containing engine oil for replenishing and supplying into an oil pan.

[Prior Art and Problem]

Normally, the self-operator does not measure the amount of oil in the oil pan well, so when the engine oil is over-consumed, air is mixed into the engine or the amount of oil supplied to the perturbation part is reduced, resulting in increased engine wear and damage to the engine. Often happens.

[Problem to Solve Invention]

Accordingly, the present invention has been proposed in view of the above problems, and its purpose is to maintain the amount of engine oil in the oil pan at a certain level or higher than the lower limit, thereby providing a means for solving the engine damage problem due to lack of lubricant. It is.

[Means for achieving the task]

Means of the present invention for achieving the above object comprises an oil storage tank for supplying oil to the oil pan through the oil supply line, and a solenoid valve for opening and closing the oil supply line by the on / off operation, A float formed to float on the oil level in the fan, and having a movable body made of a conductor formed at an end portion of the connecting rod elongated upwardly; It is formed on the upper side of the oil pan, and the movable body is formed to be movable up and down between the upper terminal (power off terminal) and the lower terminal (power on terminal) formed to have a predetermined interval so that the movable body moves up and down, the upper terminal or the lower terminal. A chamber switch for supplying or cutting off power to the solenoid valve depending on whether the contact is made; And an electronic controller for controlling the solenoid valve to enter an operating state after a predetermined time when the engine is turned off.

EXAMPLE

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

1 is a view showing a lubricating oil supply device provided with an auxiliary tank for accommodating the engine oil of the present invention.

In the drawing, reference numeral 1 denotes an oil pan, and the float 2 is embedded in the oil pan 1 in a state of floating on the oil surface.

On the upper side of the float 2, a constant length connecting table 2a is formed, and at the end of the connecting table 2a, a moving body 6 made of a conductor is formed.

The float 2 is connected to the float chamber switch 3 by the movable body 6 and is disposed between the upper terminal 4 (power off terminal) and the lower terminal 5 (power on terminal) constituting the chamber switch 3. The movable body 6 connected to the float 2 moves up and down in accordance with the oil level in order to contact the lower terminal 4 or the upper terminal 5 to supply or shut off the power to close the solenoid valve 7. It is opened and closed.

The solenoid valve 7 is installed on the oil supply line 9 extending from the oil storage tank 8, which is an auxiliary tank installed on the upper side, into the lower oil pan 1, and the float 2 descends to move the movable body 6 ) Contacts the lower terminal 5 to open the conduit 9 to supply the oil in the upper oil storage tank 8 to the oil pan 1 and the water level rises so that the movable body 6 moves to the upper terminal 4. When it comes in contact with it, it turns off to block the conduit 9.

On the other hand, the solenoid valve 7 does not operate because the oil level is shaken while the vehicle is in operation. The solenoid valve 7 is required to stabilize the oil level for a certain time after detecting the ignition key off signal by the electronic controller 10. After the elapse of a second or so, the solenoid valve 7 is controlled to be in an operating state, and as described above, the oil supply resumes depending on whether the switch is operated according to the oil level.

[effect]

According to the present invention as described above, even if the driver skips the check of the engine oil level within a certain mileage to replace the engine oil, it is automatically supplemented and supplied from the oil storage tank stored separately according to the oil level in the oil pan, so that the engine wear and There is an effect to prevent damage to the engine due to the adhesion of the bearing portion.

Claims (1)

An oil storage tank for supplying oil to the oil pan through the oil supply line, and a solenoid valve for opening and closing the oil supply line by on / off operation, is formed to float on the oil surface in the oil pan, and long upward A float having a movable body made of a conductor formed at an end portion of the connecting rod formed; It is formed on the upper side of the oil pan, and the movable body is formed to be movable up and down between the upper terminal (power off terminal) and the lower terminal (power on terminal) formed to have a predetermined interval so that the movable body moves up and down, the upper terminal or the lower terminal. A chamber switch for supplying or cutting off power to the solenoid valve depending on whether the contact is made; Lubricating oil supply apparatus for an engine oil replenishment auxiliary tank is installed, characterized in that it comprises an electronic control for controlling the solenoid valve to enter the operating state after a predetermined time when the engine start key off.
