ABSTRACT:
The present invention is a damper seal which is used in sealing a tube, such as a fuel nozzle, into a housing, such as a fuel canister. The damper seal provides increased sealing capabilities as the pressure inside the housing increases and further dampens vibrations which may occur between the housing and the tube. The damper seal includes a damper portion having outer and inner longitudinally extending scallops to define outer and inner contact surfaces for the damper seal. The inner and outer scallops are circumferentially offset from each other to enhance the vibration dampening characteristics of the damper seal. In addition, inner and outer seals having a U-channel located therebetween are provided for sealing against a tube and a housing, respectively, wherein the U-channel facilitates a positive biasing of the inner and outer seals into engagement with cooperating surfaces in the presence of a fluid pressure.
