The openend that gasket coordinates is equipped with the edge radially extended, is welded between the edge and bottom end cover inner wall through ultrasonic welding process
It is fixedly connected.
Further, the bottom end cover inner wall opens up jagged, and the edge is embedded in the notch and edge and lower end
Lid inner wall edge links up smoothly.
Further, the bypass valve base reinforced three-legged structure of openend outer wall and the edge transition radially extended are held in the mouth
Connect.
Further, the gasket inner side end is equipped with boss structure, the boss neighboring and gasket neighboring it
Between leave annular groove, the spring one end is assemblied in the annular groove.
Further, the upper and lower end cap is to strengthen the upper and lower end cap that nylon is made, upper and lower end cap and filter paper
Between fixed respectively by thermal weld technique through thermal weld.
Using the above scheme, by-passing valve is installed, 2. bypass valve bases pass through in the element kit assembly of the utility model
Ultrasonic welding process welds together with bottom end cover, and bypass valve opening pressure is controlled by adjusting case of by-pass valve parameter.
After filter paper blocks.Pressure rise, by-passing valve are opened, and machine oil directly feeds engine through bottom end cover bottom, avoid engine because
Engine oil supplying deficiency is damaged；Increase security performance；Gasket end face outside, which is caught at the L-type step of bottom end cover, forms spacing match somebody with somebody
Conjunction prevents gasket from deviating from；The openend for bypassing valve base is embedded in formation stabilization in the notch of bottom end cover by the edge radially extended
The firm fit structure and reinforced structural transition of the corner plays humidification；Gasket inner side end is by boss structure
Spring provides installation site；Fixed up and down between end cap and filter paper by thermal weld and replace gemel connection of the prior art, more ring
Protect.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Attached drawing 1 is the utility model specific embodiment structure diagram；
Attached drawing 2 is the utility model specific embodiment partial structurtes enlarged drawing；
