Abstract

The utility model discloses a spin-on type oil filter comprising a filter seat, a casing, a filter element, an upper end cover and a lower end cover. The utility model is characterized in that the filter element is composed of a full flow filter element and a bypass flow filter element. The inner side wall of the full flow filter element is provided with a filter screen and sheathed with venturi tubes in concentricity. The bypass flow filter element is piled up by filter paper with trapezoid holes and triangular holes. The filter seat is connected with the casing in an inner winding sealing mode. The utility model can meet the demand of fuel feed when an engine is started in a cold mode. The utility model has the advantages of good sealing property, compact structure and beautiful appearance and prolongs the service life of the engine greatly.

Description

Rotary mounting engine oil filter

Technical field

The utility model relates to the filter cleaner of motor, specifically a kind of rotary mounting engine oil filter.

Background technique

In the prior art, the oil filter of motor is usually designed to and has bypass valve arrangement, when the engine cold-start fuel feeding need increase or additionally fuel feeding increases, can open bypass valve, to guarantee fuel feeding, the vibration of motor makes the easy seal failure of sealing gasket of conventional design in addition, leaks serious, can not guarantee the proper functioning of motor, influence working life.

Summary of the invention

The purpose of this utility model is a kind of rotary mounting engine oil filter that designs at the deficiencies in the prior art, the fuel feeding needs when it can satisfy engine cold-start, and good seal performance has prolonged working life of motor greatly, compact structure, outward appearance is more beautiful.

The concrete technological scheme that realizes the utility model purpose is: a kind of rotary mounting engine oil filter, comprise filter block, housing, filter core, upper and lower end cap, inside and outside seal ring, be characterized in that filter core is fixed in the housing by spring by upper and lower end cap respectively, filter block seals with the interior coiling of housing and is connected, and is set with exterior seal ring, inner seal ring on the filter block; Described filter core is made up of full stream filter core, by-pass flow filter core, be provided with middle end cap between full stream filter core and the by-pass flow filter core, flow the filter core inwall entirely and be provided with filter screen, Venturi tube is housed with the filter screen concentric locking collar, one end of Venturi tube and the center hole socket of middle end cap, the other end is fixed on the upper end cap; Described by-pass flow filter core is to be formed by the every superimposed accumulation of filter paper that has trapezoidal hole, delthyrium, dihedral sidewall; The mesh of described filter screen is the flange and the both sides opening of number row helical arrangement; The two ends of described inner seal ring are provided with neck; One end of described exterior seal ring is provided with flange;

Fuel feeding needs when the utility model can satisfy engine cold-start, good seal performance has prolonged working life of motor greatly, compact structure, outward appearance is more beautiful.

Embodiment:

Consult Fig. 1,2, the utility model comprises filter block 1, housing 10, filter core 12, upper and lower end cap 2,8, and filter core 12 is sleeved in the housing 10, spring 9 be contained at the bottom of the shell and lower end cap 8 between, filter block 1 is connected with housing 10.Filter core 12 is made up of full stream filter core 4, by-pass flow filter core 7, it is fixed by spring 9 by upper, middle and lower end cap 2,6,8 respectively, full stream filter core 4 inwalls 13 are provided with filter screen 5, with filter screen 5 concentric locking collars Venturi tube 3 is housed, center hole 11 sockets of one end of Venturi tube 3 and middle end cap 6, its the other end is fixed on the upper end cap 2, and inner seal ring 14 is installed between upper end cap 2 and the filter block 1, and exterior seal ring 15 is sleeved on the filter block 1.

Consult Fig. 3, by-pass flow filter core 7 is to be formed by folding corresponding mutually accumulation of the continuous regular hexagon filter paper that is provided with trapezoidal hole 16, delthyrium 17, dihedral sidewall 29, and the dihedral sidewall 29 that is located on the regular hexagon limit can guarantee that by-pass

flow filter core

7 and 10 of housings have passage 27.

Consult Fig. 4, flange 19 both sides on the filter screen 5 are arranged with opening 18, and flange 19 is arranged in the shape of a spiral.

Consult Fig. 5,6,7,8, the two ends of inner seal ring 14 are provided with

neck

20,21, and neck 20 is installed in the Venturi tube 3, and neck 21 is sleeved on the filter block 1; One end of exterior seal ring 15 is provided with flange 22, and with flange 25 clampings of housing 10, coiling sealed and is connected in the flanging 23 of filter block 1 was bited into by the seal 24 and the flange 25 of housing 10.

The utility model is work like this, need filtered liquid to enter from the feed liquor 26 of filter block 1, enter filter core 12 by passage 27 then, after liquid is by by-pass flow filter core 7 by the center hole 11 and the filter liquide that flows out from full stream filter core 4, filter screen 5 of middle end cap 6, enter Venturi tube 3 together, the outlet 28 from filter block 1 at last enters motor.
