The purpose of this utility model can be realized by following technical proposal: a kind of wear-resisting high temperature resistance turbocharged engine
With valve oil seal, including skeleton and the rubber bodies being fixed on skeleton, it is characterised in that: if being provided with arterial highway annular inside rubber bodies
Sealing lip, if sealing lip cross section, arterial highway undulate, sealing lip back is provided with cannelure, is cased with Packing spring in cannelure, close
Being provided with back pressure lip below envelope lip, skeleton is provided with the annular flange being embedded in rubber bodies, and annular flange is positioned at sealing lip and back pressure
Between lip, flange inner ring surface being fixed with some bar shaped support bars being coated in rubber bodies, some support bars are along flange
Circumferentially distributed and the most extended, support bar between Packing spring and sealing lip, if support bar be bent to form with
The waveform that arterial highway sealing lip cross sectional shape is correspondingly arranged, and be corresponding in turn to arrange at sealing lip fold.
This valve oil seal uses multiple sealing lips, enhances the sealing lip enclasping force to valve guide rod, can preferably fit
Answer the working environment of turbocharged engine high pressure.Utilize simultaneously support bar and in support bar formed waveform curved
Rolling over, and fitted seal spring can improve multiple sealing lips stability, the back pressure lip below sealing lip is used for stopping pressure, reduces gas
Door conduit sintering, can reach more preferable self-lubricating state, promote the intake and exhaust performance of electromotor.
In above-mentioned one wear-resisting high temperature resistance turbocharged engine valve oil seal, also include back pressure spring, and
Support bar under some bar shapeds being coated in rubber bodies fixing with flange inner ring surface, some lower support bars divide along flange circumference
Cloth, and the most extended, and lower support bar end is bent to form kink outside back pressure lip, and back pressure spring housing is some curved
On outside the back pressure lip that folding part is corresponding.
Therefore can improve back pressure lip stability, avoid back pressure spring to eject simultaneously.
In above-mentioned one wear-resisting high temperature resistance turbocharged engine valve oil seal, described support bar and lower
Stay is that spring steel is made.
In above-mentioned one wear-resisting high temperature resistance turbocharged engine valve oil seal, described skeleton uses carbon nitrogen altogether
Ooze heat treatment mode to make.
Ensure that its hardness number is 350～580HV.
Compared with prior art, this utility model has the advantage that
This valve oil seal preferably adapts to the actual working environment of turbocharged engine, promotes the intake and exhaust of electromotor
Can, the burning making engine interior is more abundant.The service life making valve oil seal is extended, thus extends turbocharging and send out
The service life that motivation is overall.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, a kind of wear-resisting high temperature resistance turbocharged engine valve oil seal of this utility model, including
Skeleton 1 and the rubber bodies 2 being fixed on skeleton 1, if being provided with arterial highway annular seal lip 21 inside rubber bodies 2, if arterial highway sealing lip
21 cross section undulates, sealing lip 21 back is provided with cannelure 22, is cased with Packing spring 3, below sealing lip 21 in cannelure 22
Being provided with back pressure lip 23, skeleton 1 is provided with the annular flange 11 being embedded in rubber bodies 2, and annular flange 11 is positioned at sealing lip 21 and the back of the body
Between pressure lip 23, flange 11 inner ring surface is fixed with some bar shaped support bars 12 being coated in rubber bodies 2, some upper supports
