Detailed Description

As shown in fig. 1 to 7, the utility model relates to an adapter of a gasoline engine oil filter, which comprises an adapter body 1, wherein the front side surface of the adapter body 1 is a cylinder body mounting surface 3 connected with an engine cylinder body, the cylinder body mounting surface 3 is provided with an inner cavity in a concave manner, a sealing ring groove 5 for positioning a sealing ring is further arranged on the cylinder body mounting surface 3 outside the inner cavity, and the closed sealing ring groove 5 is convenient for the design of the sealing ring, so that the sealing performance is better; in addition, still be equipped with the mounting hole on the cylinder body installation face 3, can fix the adapter on the cylinder body and convenient the dismantlement through the bolt, but reuse.

The middle part of the inner cavity is provided with an oil inlet cavity 6 and an oil outlet cavity 10 in an isolation way through a partition plate 4; an oil inlet hole 7 is formed in the bottom of the oil inlet cavity 6; the side wall of the partition plate 4 close to the oil outlet cavity 10 is provided with a reinforcing rib 2, and the reinforcing rib 2 extends from the middle part of the side wall of the partition plate 4 to the upper side wall of the oil outlet cavity 10; through increasing strengthening rib 2 in the baffle 4 department in oil feed chamber 6 and oil outlet chamber 10, both reduced 4 department wall thicknesses of baffle, reduce cost, improved intensity and rigidity here simultaneously greatly, reduced fluid to the long-term high pressure erosion of here, improve the life of filter adapter.
