The present invention relates to a variable oil pump using an extra oil pressure, and more particularly, to a variable oil pump using an extra oil pressure to control the oil discharge amount and the discharge pressure by adjusting the pressure in the oil pump using a governor. It is about.

The purpose of the automobile lubrication mechanism is to supply oil to each bearing part or sliding part in the engine to secure fluid lubrication on the sliding surface, thereby reducing friction or wear and cooling the sliding part. In automobiles, the lubricating oil accumulated in the oil pan is sucked up for lubrication and cooling inside the engine and pumped to bearings or sliding parts such as crankshafts, camshafts, pistons, and the like to reduce the friction and operate smoothly.

However, in the case of the opening of the conventional automotive lubricant, the oil pump and the engine are directly connected by the crankshaft. As the engine rpm increases, the amount of oil returned through the oil bypass passage increases, so that the pressure beyond the required hydraulic pressure is operated. The loss of the power of the car and the load on the relief spring for adjusting the hydraulic pressure increases, the resistance of the oil is generated, the friction heat of the oil is generated, the oil pollution is increased, the oil change cycle is shortened.

The technology developed to compensate for this is an engine load sensitive variable oil pump using a BLDC motor, which detects the engine's rmp and travel speed to detect the engine load and sends a signal from the ECU to the BLDC motor to rotate at high or low speed. To control the proper oil volume and discharge pressure.

However, the additional use of the BLDC motor is a cause of the increase in the automobile manufacturing cost, there is a problem that causes the increase in the fuel economy by the increase of the car weight due to the increase in the weight of the BLDC motor.

The present invention has been made to solve the above problems, an object of the present invention is to adjust the pressure in the oil pump using a governor to control the oil discharge amount and the discharge pressure variable oil using an extra oil pressure In providing a pump.

The present invention has the following configuration to achieve the above object.

Variable oil pump using the extra oil pressure of the present invention, the pump is provided on the oil pipeline and provided between the bypass line; And a pressure adjusting unit provided in the bypass line, wherein the pressure adjusting unit is operated by a pressure line connected to an oil line and an oil pressure acting on the pressure line, and by a cylinder to control the bypass line. It is characterized in that to adjust the oil pressure and the oil amount of the oil duct.

In addition, the bypass line is circulated between the oil line and the pump according to the oil pressure and flow rate change on the oil line through the pressure control unit, the pressure control unit and the pressure line connected to the oil line, and the pressure line on one side Composed of a pressing piece and a cylinder which is extended to the lower side of the pressing piece and supported by a spring, the cylinder is raised and lowered according to the oil pressure introduced into the pressurized conduit to open and close the bypass line.

And it is preferable that the pressure line is located at the front end of the bypass line.

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

As shown in FIG. 1, the variable oil pump is positioned between the bypass line 120 and the bypass line 120 provided on the oil conduit 110 through which oil is transferred. ) And a pressure control unit 200 for recycling the oil and adjusting the pressure and the flow rate according to the oil pressure and the oil amount transferred by the pump 100. The pump 100 is directly connected to the crank shaft of the engine and is driven at the same speed as the engine rotation. That is, the pump to adjust the oil supply amount in accordance with the engine speed. The pump 100 is a well-known technology that is configured on the vehicle engine side and a detailed description thereof will be omitted. In addition, the oil pipeline 110 is connected to the engine from the oil tank.

The pressure adjusting unit 200 extends to one side of the pressure pipe 226 connected to the oil pipe 110 and the pressure piece 222 and the pressure piece 222 connected to the pressure pipe 226. It is made of a provided cylinder 220 and the lower portion of the cylinder 220 is provided with a spring 228 for holding the cylinder 220 and the guide member 210 for guiding the cylinder 220 to move in the vertical direction, The guide member 210 forms a plurality of flow paths 212 in communication with the bypass line 120, and the cylinder 220 forms a flow path 224 corresponding to the flow path 212. As the cylinder 220 moves up and down, each of the flow paths 212 and 224 are in communication with each other, and the oil is interrupted.

For example, as shown in FIG. 2, the pump 100 is used to transfer oil to the engine side. The engine and the pump are operated by the same rotational speed, and thus, when the engine rotational speed increases, the oil supply by the pump also increases. At this time, the oil pressure flowing from the tank is called P1, the oil pressure supplied to the engine side is called P2, and when the pressure of the spring 222 is called P3, when the oil is transferred to the amount of oil required by the engine and the pressure, The pressure in the pressure line 226 and the oil line 110 pressure P2 acts the same, so that even when the pressure piece 222 is pressurized, the spring 228 pressure P3 is larger than the oil line pressure P2, so that the cylinder ( 220 does not fall. That is, it is possible to set the spring 228 pressure P3 and the appropriate pressure required by an engine on the same conditions beforehand. For example, if the engine inlet pressure is greater than 3.5kgf / cm2 and the spring pressure is set, the spring will only be lowered if it is above the inlet pressure.

In addition, when the engine speed is increased, the rotational force of the pump is increased to increase the pressure applied to the engine side. At this time, the pressure P2 of the oil pipeline 110 acts as the pressure pipeline 226, and this working pressure When the pressure P2 is greater than the pressure P3 of the spring 228, the pressure piece is lowered by the pressing force of the pressure line 226, and the cylinder 220 is lowered. In addition, the descending cylinder 220 communicates with the bypass line 120 and the flow paths 212 and 224 and introduces the oil, and the introduced oil is introduced into the bypass line 120 and the oil conduit 110 by the pump 100. By returning, recycling and reducing the oil entering the engine side, this allows the oil side pressure and flow rate to be adjusted.

In other words, when the amount of oil and pressure required by the engine is introduced, the engine can reduce the power loss caused by the oil by circulating the oil through the bypass line to adjust the pressure of the oil flowing into the engine. It will be.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

According to the present invention, the oil discharge amount and the discharge pressure can be controlled by adjusting the pressure in the oil pump using the governor.
