Description

Oil Strainers For Automotive Engines

The present invention relates to an oil strainer of an automotive engine, and more particularly, an oil of an automotive engine capable of preventing air from being mixed by configuring the oil strainer in the oil pan to always be immersed in the oil as the vehicle is inclined. It is about a strainer.

In general, the automotive lubricator serves to continuously supply the engine oil to the kinetic friction part until the engine operates smoothly and reaches the end of its service life. It is adopted. The splash pump type pumps the lubricating oil sucked through the oil strainer to each lubricating part, and scatters the lubricating oil stored in the oil pan at the most end of the connecting rod to the cylinder wall and the piston pin. In such a lubrication device, an adequate amount of oil must be maintained at all times in order to sufficiently supply oil to each lubrication part of the engine and to operate the engine in an optimal state.

1 is a cross-sectional view schematically showing the configuration of a general automotive engine, Figure 2 is an enlarged view of a portion of a conventional oil strainer. As shown in FIG. 1, an oil pan 4, in which engine oil is stored, is attached to a lower portion of the cylinder block 2, and in the oil pan 4, oil sucking oil in accordance with the operation of an oil pump. A strainer 6 is provided. An oil screen 8 is fitted at the end of the oil strainer 6 to prevent the inflow of foreign matter.

In the conventional oil strainer having such a configuration, when the vehicle traveling on the slope is inclined, the oil in the oil pan 4 is directed to one side, and as shown in FIG. 2, the air inside the engine is passed through the oil screen 8. In addition, the blow-by gas is mixed to reduce the engine performance.

The present invention devised to solve such a problem is to provide an oil strainer for an automotive engine that can prevent the mixing of gas by allowing the oil screen is always locked in the oil pan regardless of the inclination of the vehicle. have.

The object of the present invention described above is a first oil pipe attached to the lower end of the oil pump, a second oil pipe connected to the lower end of the first oil pipe via a bellows, the oil screen is fitted at the lower end, bellows at one end A first clamp coupled to the end of the first oil pipe is attached via the other end, the other end is a link consisting of a branch end having a through hole, the upper end is coupled to the branch end of the link, the lower end is a second through the bellows It is achieved by an oil strainer of an automotive engine, characterized in that it consists of a hanger with a second clamp attached to the top of the oil pipe.

According to the present invention, the oil screen is always immersed in the oil by the oil strainer interlocked with the inclination of the vehicle, thereby preventing the incorporation of gas and preventing deterioration of engine performance.

Hereinafter, an oil strainer of an automotive engine according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

Figure 3 is a cross-sectional view showing a coupling state of the oil strainer according to the present invention, Figure 4 is an exploded perspective view showing the configuration of the link and the hanger employed in the present invention, the same parts as the conventional structure described in Figures 1 and 2 The same code is used.

First, as shown in Figure 3, when the schematic configuration of the oil strainer according to the present invention, the first oil pipe 16 attached to the lower end of the oil pump 10, and the impurities contained in the oil at the bottom Second oil pipe (18) to which oil screen (20) for filtering the oil is attached, and links (22) and hangers (15) to flexibly connect these oil pipes (16) and (18) via bellows (48). 32).

Here, a first clamp 28 coupled to the end of the first oil pipe 16 is attached to one end of the link 22 via the bellows 48, and the other end of the link 22 is attached to the hanger by a bolt 44. 32) is connected to move freely. In addition, a lower end of the hanger 32 is attached with a second clamp 38 coupled to the upper end of the second oil pipe 18 via the bellows 48.

That is, the link 22 is firmly fixed to the end of the first oil pipe 16 by the first clamp 28, and the hanger 32 is freely attached to the end of the link 22 by the bolt 44. Since it is installed to flow, even if the vehicle is inclined, the oil screen 20 attached to the bottom of the hanger 32 is always kept submerged in oil.

4 shows a link and a hanger employed in the present invention. As shown here, one end of the link 22 is attached to the first clamp 28, which is coupled to the end of the first oil pipe 16 by a bolt 42, the other end is a through hole 26 It consists of a branch end 24 having a. In addition, the upper end 34 of the hanger 32 is fluidly coupled to the branch end 24 of the link 22 by the bolt 44 and the nut 30, and the lower end of the second oil by the bolt 46. The second clamp 38 to which the pipe 18 is coupled is attached.

According to the present invention described above, the oil screen is always immersed in the oil by the oil strainer interlocked with the inclination of the vehicle, thereby preventing the incorporation of gas to prevent degradation of engine performance.
