ABSTRACT:
An improved fluid seal device or pressure seal of the type suitable for uses such as sealing an annular space between an internal surface and a member having an outer cylindrical surface is described. The seal includes a reinforced body formed of fabric reinforced rubber and at least one dynamic lip made substantially of rubber. The lip protrudes from the seal so that a small portion of the lip contiguous to the body of the seal and containing fabric reinforcement is contacted by the movable member in addition to the movable member contacting the resilient portion of the lip. The resilient portion of the lip hinges along the interface between the resilient portion and the fabric reinforced portion to control break-away frictional forces between the seal and the member.
