Slot, the locating slot are located at sealing strip side.
Further, the locating slot has corresponding filling block.
Further, the close cellular type flexible layer and oil-yielding stratum make for polytetrafluoroethylene (PTFE), the close cellular type flexible layer
It is marked with lubricating oil in close hole.
Compared with prior art, the present invention has the advantages that：
1. by the braiding structure feature of oil-deflecting type polytetrafluoroethylene (PTFE) braiding layer, the elasticity of polytetrafluoroethylene (PTFE) is remained
Lubricating oil in close cellular type flexible layer can also effectively be discharged in the fuel-displaced micropore of oil-yielding stratum, and be squeezed in piston by feature
When, pressure can be efficiently used and squeeze out the lubricating oil in close cellular type flexible layer by the pore of oily micropore, be effectively increased piston work
The lubricity of work.
2. by the setting of locating slot, personnel can practical specification demands shearing tune is carried out to one end of locating slot on sealing strip
It is whole, can be embedding as in locating slot, formed sealing ring by locating button after adjusting, and extra locating slot is filled out using filling block insertion
It fills, to ensure sealing strip integrality, and will be formed in the embedding such as piston bush of sealing ring at corresponding filler.
