Abstract:

An inlet duct and seal assembly is disclosed having, as its preferred application, the attachment of an intake air transfer duct to the throttle body of an internal combustion engine. The throttle body is provided with an inlet opening about which extends an annulus defining an outer annular wall. The inlet air duct has an opening which corresponds in diameter to that of the annular outer wall. A seal is disposed in the duct opening and includes an inwardly, radially directed wiper seal which is flexibly deformed between the annular wall and the duct opening when the duct opening is engaged over the throttle body inlet. A pivot clip extends from the inlet duct to engage a shelf on the throttle body to thereby position the duct opening with respect to the throttle body annulus to assure a proper seal and to simplify assembly of the components,.
