[0028] Rubber pad 2 is integrally formed at the top center of the rubber pad 1. Rubber pad 2 has a compression friction groove 8 at the top. Rubber pad 2 has a rubber pad 2 limiting groove 9 at the bottom center of the oil pump base 1. A compression friction block 10 is provided at the bottom of the rubber pad 2 limiting groove 9. Rubber pad 2 and rubber pad 2 limiting groove 9 are matched and fitted to facilitate rubber pad 2 7 being limited inside rubber pad 2 limiting groove 9. Compression friction groove 8 and compression friction block 10 are matched and fitted to facilitate compression friction block 10 being limited inside compression friction groove 8. A mesh groove 11 is provided at the bottom of rubber pad 1.

[0029] The specific implementation method is as follows: When installing the oil pump body 12, rubber pad 2 7 is inserted into the rubber pad 2 limiting groove 9 at the bottom of the oil pump base 1, and the squeezing friction block 10 is embedded inside the rubber pad 2 limiting groove 9. The top of rubber pad 1 2 is attached to the bottom of the oil pump base 1. At this time, the positioning post 5 on the gasket 4 is inserted into the positioning hole 6.

The installation is tightened by passing bolts through mounting hole 1 13, mounting hole 2 14 and the mounting surface. When the bolts continuously squeeze the oil pump base 1, the oil pump... As the oil pump base 1 moves toward the mounting surface, the rubber pad 2 between the oil pump base 1 and the mounting surface is compressed and deformed, fully filling the space between the oil pump base 1 and the mounting surface. When the rubber pad 2 deforms to a certain thickness, the oil pump base 1 contacts the gasket 4, and the gasket 4 limits the oil pump base 1 from continuing to move.
