Seal ring and power steering valve device provided with it |
| abstract |
The present invention relates to a seal ring comprising 40nto 94 % by weight of polytetrafluoroethylene powder and 6 to 60 %nby weight of aromatic polyoxybenzoylester heat resistant resinnpowder or 40 to 94 % by weight of polytetrafluoroethylene powder, 3nto 30 % by weight of aromatic polyoxybenzoylester heat resistantnresin powder and 3 to 30 % by weight of molybdenum disulfidenpowder or 3 to 30 % by weight of tungsten disulfide powder. Thenseal ring has little deformation by bulging of the seal even whennused under pressure, can restrict the abrasion of a contactingnmaterial even when made of soft metal, providing a stable sealingneffect over a long period. Furthermore, the seal ring is low innfriction and change in sliding torque and therefore can significantlynimprove control and response of a device equipped with the seal ring.nAlso, the present invention provides a power steering valve device,nan automatic transmission which slides at a high rotation speednand a shock absorber which requires sealing in a reciprocatingnsliding environment, which are equipped with the above seal ring. |
