Abstract
The utility model discloses a kind of valve guide bushing, comprise catheter body, the annular end face of the upper end of catheter body is crossing with the inner hole wall line of catheter body.This valve guide bushing is by cancelling former valve guide bushing top inner bore chamfering, and have water conservancy diversion inclined-plane in the upper design of valve guide bushing, alleviate the suction machine oil effect by valve and valve guide bushing gap in engine running, effectively avoid the generation of motor " burn oil " and " outlet pipe lubricating oil leakage " fault.
Description
Technical field
The utility model relates to engine art, particularly a kind of valve guide bushing.
Background technique
In the distribution device of motor, valve guide bushing is the guiding device of engine valve, and as depicted in figs. 1 and 2, the endoporus on existing valve guide bushing 10 top is all designed with chamfering 101.Therefore, at the easy trapped fuel in chamfering 101 place, in valve 20 works, easily cause the generation of motor " burn oil " and " outlet pipe lubricating oil leakage " fault.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of valve guide bushing, by cancelling former valve guide bushing top inner bore chamfering, and have water conservancy diversion inclined-plane in the upper design of valve guide bushing, alleviate the suction machine oil effect by valve and valve guide bushing gap in engine running, effectively avoid the generation of motor " burn oil " and " outlet pipe lubricating oil leakage " fault.
For achieving the above object, the utility model provides a kind of valve guide bushing, comprises catheter body, and the annular end face of the upper end of catheter body is crossing with the inner hole wall line of catheter body.
Preferably, the outer wall of the upper end part of catheter body is taper.
Preferably, the annular end face of the upper end of catheter body is obliquely installed.
Compared with prior art, the utility model has following beneficial effect: by cancelling former valve guide bushing top inner bore chamfering, namely the annular end face of the upper end of catheter body and the inner hole wall line of catheter body crossing, further by design water conservancy diversion inclined-plane, strengthen the guide functions of lubricant oil, the lubricant oil of the upper end deriving from catheter body is slipped away as early as possible, avoid the suction machine oil effect by valve and valve guide bushing gap in engine running further, effectively avoid the generation of motor " burn oil " and " outlet pipe lubricating oil leakage " fault.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 3 and 4, according to a kind of valve guide bushing of the utility model embodiment, comprise catheter body 1, the annular end face 12 of the upper end of catheter body 1 is crossing with inner hole wall 11 line of catheter body 1.So-called line intersects, namely the upper-end surface of the direct transtracheal catheter body 1 of the inner hole wall 11 of catheter body 1 forms annular end face, also the chamfering structure (participation Fig. 2) of original valve guide bushing top endoporus is namely cancelled, by this change, machine oil can not be accumulated on the top of valve stem and valve guide bushing, the suction machine oil effect by valve and valve guide bushing gap in engine running can be alleviated like this, effectively avoid the generation of motor " burn oil " and " outlet pipe lubricating oil leakage " fault.
As shown in Figures 5 and 6, as a kind of preferred embodiment, the annular end face 12 of the upper end of catheter body 1 is obliquely installed, particularly, annular end face 12 is α with the angle of horizontal plane, the annular end face 12 be obliquely installed can strengthen the guide functions to lubricant oil, avoids the suction machine oil effect by valve and valve guide bushing gap in engine running further.
As shown in Figures 7 and 8, as another kind of preferred embodiment, conical surface 13 is designed at the outer wall of the upper end part of catheter body 1, angle between conical surface 13 and annular end face 12 is β, conical surface 13 can strengthen the guide functions to lubricant oil equally, the lubricant oil of the upper end deriving from catheter body 1 is slipped away as early as possible, avoids the suction machine oil effect by valve and valve guide bushing gap in engine running further.
In a word, the valve guide bushing of the present embodiment, by cancelling former valve guide bushing top inner bore chamfering, namely the annular end face 12 of the upper end of catheter body 1 and inner hole wall 11 line of catheter body 1 crossing, further by design water conservancy diversion inclined-plane, strengthen the guide functions of lubricant oil, the lubricant oil of the upper end deriving from catheter body 1 is slipped away as early as possible, avoid the suction machine oil effect by valve and valve guide bushing gap in engine running further, effectively avoid the generation of motor " burn oil " and " outlet pipe lubricating oil leakage " fault.And this structure is simple, easily manufactures.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
