Abstract
The utility model discloses a kind of electric fuel punp check valve spring seat, comprise spring seat body, described spring seat body comprises retaining ring, one of them end face of described retaining ring is evenly distributed with multiple supporting post, gap is had between described supporting post, directional post is connected with retaining ring by described supporting post, described directional post is between all supporting posts, and there is distance between one end of described directional post and retaining ring, the other end of described directional post reaches outside the space that supporting post surrounds, described directional post is provided with axis hole vertically, and described axis hole is square opening.The utility model structure is simple, reasonable in design, by columniform axis hole is revised as square opening and prism, realizes square spacing like this, avoids inner elements of check valve to rotate, thus avoids the different sound that brings because of rotation and friction.Check valve spring seat body structure is simple, and assembling easily.
Description
Technical field
The utility model relates to a kind of electric fuel punp check valve spring seat.
Background technique
Electric fuel punp is for the vitals in the electric control fuel oil jet system in passenger car petrol engine, passenger car oil machine, diesel engine of commercial vehicle etc., the effect of fuel pump is mainly transported to after fuel oil sucking-off from fuel tank, pressurization in fuel supply line, and certain fuel pressure is set up in fuel pressure regulator cooperation.General fuel pump comprises the pump housing and pump head component, pump head component comprises one-way valve and check valve spring seat, one-way valve comprises spheroidal spool, valve core case and coupling shaft, spring seat is provided with directional post, the coupling shaft of current one-way valve is cylindrical, the axis hole of the directional post of corresponding spring seat is also cylindrical, like this, fluid by time, one-way valve spheroidal Spool rotating, coupling shaft also and then rotates in directional post, cause rotating different sound, riding comfort reduces, simultaneously, due to spin friction, by the appearance of phenomenons such as causing follow-up one-way valve poorly sealed.
Model utility content
For existing problem, the purpose of this utility model is that providing a kind of eliminates the electric fuel punp check valve spring seat rotating different sound.
To achieve these goals, the technical solution of the utility model is: a kind of electric fuel punp check valve spring seat, comprise spring seat body, it is characterized in that: described spring seat body comprises retaining ring, one of them end face of described retaining ring is evenly distributed with multiple supporting post, gap is had between described supporting post, directional post is connected with retaining ring by described supporting post, described directional post is between all supporting posts, and there is distance between one end of described directional post and retaining ring, the other end of described directional post extends to outside the space that supporting post surrounds, described directional post is provided with axis hole vertically, described axis hole is square opening.
Adopt such scheme, at the inwall of pump head component one-way valve valve body corresponding retaining ring, annular groove is set, retaining ring is arranged in this annular groove, is also designed to by inner elements of check valve coupling shaft corresponding with the axis hole of directional post square, like this, fluid is when passing through, would not rotate at square spacing lower unidirectional valve circle spherical valve core, can not abnormal sound be produced, simultaneously, the friction that one-way valve spheroidal Spool rotating causes can also be avoided, thus the appearance of the problems such as the poorly sealed reality caused.Directional post is connected with retaining ring by supporting post, and like this when one-way valve opens, fluid passes through from the gap between supporting post, then is gone out in fuel pipe by retaining ring center hole.The other end of directional post reaches outside the space that supporting post surrounds, and after being set with upper spring like this, spring is directly against on the end face of supporting post, need not setting table terrace mounting spring separately, and structure is simple.
In such scheme: described supporting post is three.Three supporting posts form a circle, and directional post is arranged on wherein, save material, reasonable in design.
In such scheme: the aperture of the center hole of described retaining ring is greater than the aperture of axis hole.Be conducive to fuel-displaced like this.
In such scheme: described retaining ring, supporting post and directional post are one-body molded.Production and processing is easier.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by columniform axis hole is revised as square opening and prism, realizes square spacing like this, avoids inner elements of check valve to rotate, thus avoid the different sound that brings because of rotation and friction.Check valve spring seat body structure is simple, and assembling easily.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left side view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Embodiment 1
As shown in Figure 1-2: electric fuel punp check valve spring seat of the present utility model comprises spring seat body, and spring seat body is made up of parts such as retaining ring 1, supporting post 2, directional post 3 and axis holes 4.
Be provided with at the inwall of one-way valve valve body the annular groove matched with retaining ring 1 near oil outlet, retaining ring 1 is contained in this annular groove.Retaining ring 1 away from the end face of oil outlet being evenly distributed with multiple supporting post 2, be preferably 3 supporting posts 2, reasonable in design like this, cost is low.Have gap between supporting post 2, fuel oil passes through from the gap between supporting post 2, then flows out from the center hole of retaining ring 1.Directional post 3 is connected with retaining ring 1 by supporting post 2, directional post 3 between all supporting posts 2, and has distance between one end of directional post 3 and retaining ring 1, specifically, this end of directional post 3 is fixed on the middle part of supporting post 2, the other end of directional post 3 reaches outside the space that supporting post 2 surrounds, and specifically, the end of supporting post 2 is positioned at the middle part of the outer side wall of directional post 3, like this, the end face of supporting post 2 is directly as the attachment face of spring, and that is, spring is directly against on this end face.Directional post 3 is provided with axis hole 4 vertically, and axis hole 4 is square opening.One-way valve comprises inner elements of check valve, one-way valve core print seat and coupling shaft, and valve core case one end is connected with spool, the other end connection chain spindle.The coupling shaft of corresponding one-way valve is also designed to square, thus realizes square spacing to one-way valve, avoid fuel oil by time one-way valve rotation, avoid consequent abnormal sound.The aperture of the center hole of retaining ring 1 is greater than the aperture of axis hole 4.Facilitate fuel-displaced like this.Retaining ring 1, supporting post 2 and directional post 3 are one-body molded.Such design processing is easier.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
