Abstract

(57) [Summary] [Purpose] To prevent air from entering even if a crack occurs in the oil strainer tube, and to enable the oil pump to suck in oil. [Configuration] One end is an automobile engine lubricating oil pump 1
The surface of the tube 6, which was connected to the oil pan and whose other end opened into the oil in the oil pan, was covered with elastic rubber 11 as an airtightness maintaining member.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is an oil storage system installed in an oil pump for automobile engine lubrication. Regarding Na.

0002

[Conventional technology]

Figure 2 shows the mounting structure of a conventional oil strainer. In Figure 2, the engine At the bottom of the engine block 1 is an oil pan in which oil 2 for lubricating an automobile engine is stored. 3 is installed. The engine block 1 is also provided with an oil pump 4. A strainer 5 is connected to the suction port of the oil pump 4. Stre The inner tube 5 is formed by bending an iron tube 6, and the upper end is connected through a flange 7. It is fixed to the suction port of the oil pump 4 with bolts 8. Also, under tube 6 The end opens into the oil 2 in the oil pan 3, and the oil pump is installed at the open end. Mesh 9, which is a dustproof member, is installed to prevent 4 from inhaling foreign matter. There is. Furthermore, in order to prevent vibration of the tube 6, the tube 6 is connected to the engine via a stay 10. It is also fixed to gin block 1.

[Problem that the idea aims to solve]

However, in the conventional oil strainer configured as above, When the oil pan 3 is deformed due to impact while driving on a rough road, the iron tube There was a risk that cracks would occur in the tube 6. As a result, a crack occurred in tube 6. The oil pump 4 is unable to suck the oil 2, and the engine This may affect the engine's ability to start and run.

0004 The present invention was developed in view of the above points, and even if cracks occur in the tube, the air will not air out. The oil tank prevents the infiltration of oil and allows oil to be sucked in by the oil pump. The purpose is to provide Lena.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the present invention has one end connected to the oil pump and the other end connected to the oil pump. The surface of the tube that opens into the oil pan is covered with an elastic airtight material. This is what I did.

[0006]

[Effect]

In the oil strainer of the present invention configured as described above, the tube surface is covered with an elastic airtight material, so it will not turn off when driving on rough roads. Even if the tube cracks due to a strong blow, the airtightness retaining member will prevent the tube from cracking. The airtightness of the pipe is maintained, and the oil pump can suck in the oil. It can function as an illumination strainer.

【Example】

An embodiment of the present invention will be described below with reference to the drawings.

[0008] FIG. 1 shows an embodiment of the present invention. In Fig. 1, the part of the conventional example shown in Fig. 2 is The same reference numerals are given to the corresponding parts in the explanation. Oil strike in this example Particularly, the surface of the tube 6 of the laner 5 is covered with rubber 11, which is an airtightness maintaining member. The structure of the other parts is the same as the conventional example shown in Fig. 2, except for the flange at the upper end. It is connected to the oil pump side through 7, and the lower end opens into the oil pan and has a mesh 9 is installed.

[0009] The rubber 11 continuously covers the entire outer circumference of the tube 6 and the surface of the flange 7. Ru. To cover this rubber 11, attach a flange 7 to one end of the tube 6 by welding or the like. After application, it is formed by dipping into molten rubber. and the rubber solidifies After that, swage the mesh 9 and attach it. The airtightness maintaining member is made of rubber material. However, in order to maintain airtightness, the surface of rubber 11 is further coated with thermoplastic resin, etc. Alternatively, instead of the rubber material, an elastic material made of thermoplastic resin or the like may be used. The tube 6 may be covered with a tubular airtightness maintaining member.

0010 According to this embodiment, the surface of the tube 6 and the joint portion of the flange 7 are covered with the rubber 11. Because the cover is covered, contact with the tube 6 and flange 7 may occur due to impact when driving on rough roads. Airtightness is maintained even if cracks occur in the joint, and oil is sucked in by the oil pump. You can Therefore, the engine can be started and run without any trouble.

[0011]

[Effect of the idea]

As explained above, according to the present invention, the surface of the oil strainer has elasticity. The tube is coated with an airtight material to provide airtightness, so in the unlikely event that the tube cracks. The oil strainer remains airtight even in the event of It can perform the function of sucking oil.
