Patent ID: 7614378

Claim:
An engine air induction duct connection comprising: a cuff, in cross-section, defining a symmetrical dovetail projection, the cuff and entire dovetail projection being a single rubber material, the dovetail projection located on an outside diameter of the cuff and perpendicular to a cuff longitudinal axis, the dovetail projection having a flat annular dovetail surface that is more distal from the cuff longitudinal axis and wider than a section of the dovetail that is between the longitudinal axis and the flat annular dovetail surface, the cuff further defining a groove formed into an inside diameter of the cuff and a clamp groove formed into the outside diameter of the cuff; a throttle body inlet defining a protuberance that resides within the groove; a nub integrally formed with the cuff, the nub protruding from the inside diameter of the cuff that contacts the throttle body inlet; a clamp, the clamp located within the clamp groove on the outside diameter of the cuff opposite to the protruding nub to provide a concentrated force at the nub on the throttle body inlet; and a duct wall, in cross-section, defining a dovetail recession in an inside diameter of the duct wall, the dovetail recession having a flat annular dovetail surface that contacts the flat annular dovetail surface of the cuff, wherein the entire dovetail projection of the cuff interlocks with the recession of the duct wall the cuff prevents contact between the throttle body inlet and the duct wall, and the groove is located adjacent to the dovetail.
