AIR DAMPER WITH GRAPHITE COATED LIP SEAL. |
摘要 |
The air damper (10) includes a piston (18) reciprocating within a cylindrical housing (12). The piston (18) includes a lip seal (30) which is made of rubber or thermoplastic elastomer impregnated with a minimum of 3% molybdenum/seal part weight, or a minimum of 2% polytetrafluoroethylene or silicone/seal part weight or a minimum of 1% wax/seal part weight. The lip seal (30) is coated with a minimum of 0.5% /seal part weight graphite powder/molybdenum disulfide. The housing (12) is made with a minimum of 2% silicone impregnated thermoplastic or a minimum of 2% moly sulfide impregnated thermoplastic. This provides for increased smoothness of operation of the air damper (10), particularly at low speeds.
