SEAL AND METHOD OF FORMING THE SEAL

摘要

A fluid seal of the present invention is disposed between an outer surface, i.e. engine block or any other part that requires application of the assembly and a rotatable member, such as, for example a shaft, wherein the seal circumscribes the shaft and lubricated the shaft and the same rotates around the axis. The seal present a cross section with plurality of channels that allow maximum expose of the seal to a salt bath thereby improving curing process and physical characteristics of the seal. A method of forming such fluid seal is disclosed in the present application.

主权项

1. A seal device for providing a seal between a cylindrical member and a housing with the cylindrical member rotatable around a central axis and relative the housing, said seal assembly comprising:
a seal member including a body portion engaging the housing, said body defining a top surface and a bottom surface; a collar member extending from said body portion and circumscribing the cylindrical member; and said body portion including a plurality of first channels defined on said top surface and extending into a first direction and a plurality of second channels defined in said body portion and extending in a second direction different from said first direction with at least some of the first channels being fluidly communicated with said second channels to reduce weigh of said seal device, increase flexibility of said seal device and form a plurality of surfaces to be expose to a salt bath for improved curing before said seal devise is formed.
