CN2921302Y - Paper end cover rotary mounting engine oil filter - Google Patents

Abstract

The utility model discloses a paper end cap spin-on engine oil filter, comprising a threaded cover plate assembly (2), a check valve (3), a filter element assembly (4), a housing (5) and a bypass valve assembly (6). The supporting spring (7) of the bypass valve assembly (6) is a sheet-type supporting spring; the end cap (8) of said filter element assembly (4) is a paper end cap, which has no vertical edge. The utility model prolongs the useful life of the filter element assembly, increases the filtration area and dust collection area of the filter element assembly, prolonging the maintenance interval and reducing the maintenance cost of the product. Moreover, the replaced filter element assembly is easy to dissolve, conserving resources and protecting the environment excellently.

Description

Xuan Paper Cover Mounted Oil Filter

One, technical field

The utility model relates to the rotary mounting engine oil filter that a kind of diesel engine, petrol engine are used.

Two, background technique

Existing rotary mounting engine oil filter is made of thread plate assembly, safety check, element kit, shell, bypass valve assembly etc.Wherein bypass valve assembly comprises case of by-pass valve, supported spring, valve body etc., its valve body is contained on the supported spring, supported spring is common spiral: in use because the compressing power that is subjected to causes element kit bending deflection to cause damaging more greatly and easily, make element kit shortening in working life; Element kit comprises folded filter paper, center tube, end cap, its end cap is a metal end: this metal end has stile part (about 5-10mm) and carries out bonding to put hot-setting adhesive, this stile part nature can cover folded filter paper (cover area account for total filter area 10%), make element kit exist deficiencies such as filter area is little, appearance dirt area is little, cause element kit to be stopped up by impurity in early days and shortened working life of element kit, cause the shortening in product working service cycle and the increase of maintenance cost.

Three, model utility content

The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of element kit that can prevent to be out of shape, to guarantee filter area that element kit is enough because of extruding and hold the Xuan Paper Cover Mounted Oil Filter of dirt area.

The purpose of this utility model realizes by following technical solution: a kind of Xuan Paper Cover Mounted Oil Filter, comprise thread plate assembly, safety check, element kit, shell, bypass valve assembly, the supported spring of described bypass valve assembly is the chip supported spring; The end cap of described element kit is a paper end cap, and this paper end cap does not have the stile part.

After adopting the utility model structure, because this chip supported spring elasticity is less, amount of deformation is little, is used with paper end cap, the suffered compressing power of element kit is diminished and is difficult to bending deflection, and can compensate other accessory size chain tolerance, prolong the working life of element kit; This paper end cap does not have the stile part, just can not cause the periphery of the folded filter paper of element kit yet and block, and has improved the filter area of element kit and has held the dirt area, has prolonged its working life.Therefore, the utility model has compared with prior art prolonged the working service cycle and the maintenance cost that has reduced product of product.And, replaced the virgin metal end cap by paper end cap, saved cost of material, the element kit that changes dissolves easily, has reduced waste, has reached the good result that economizes on resources with environmental protection.

Four, description of drawings

Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model Xuan Paper Cover Mounted Oil Filter.

Fig. 2 is the enlarged diagram of the chip supported spring of the bypass valve assembly among Fig. 1.

Fig. 3 is the known structural representation that has the element kit of metal end (having the stile part).

Five, embodiment

With reference to Fig. 1, Fig. 2 as can be known, the utility model Xuan Paper Cover Mounted Oil Filter, comprise exterior seal ring 1, thread plate assembly 2, safety check 3, element kit 4, shell 5, bypass valve assembly 6, the supported spring 7 of described bypass valve assembly 6 is chip supported spring (valve body 10 of bypass valve assembly is contained on this chip supported spring); The end cap 8 of described element kit 4 is a paper end cap, and this paper end cap does not have the stile part.This paper end cap can not cause the periphery of the folded filter paper 9 of element kit 4 and block (as shown in Figure 1); Contrast Fig. 3, the upper and lower metal end of known element kit all has the stile part A, and it covers area and accounts for about 10% of total filter area.

The utility model can strengthen the oil flow rate of diesel engine, petrol engine, guarantees the demand of engine lubrication, cooling system.Simultaneously, improved appearance dirt area and ability, effectively hindered the infringement of foreign-matter contamination motor.Thereby prolonged the working service cycle of motor and reduced maintenance cost.

Claims (1)

1, a kind of Xuan Paper Cover Mounted Oil Filter, comprise thread plate assembly (2), safety check (3), element kit (4), shell (5), bypass valve assembly (6), it is characterized in that: the supported spring (7) of described bypass valve assembly (6) is the chip supported spring; The end cap (8) of described element kit (4) is a paper end cap, and this paper end cap does not have the stile part.
