ABSTRACT:
A throttle body (61) has a first body part (62) containing an upstream portion of the through-bore (68) and a second body part (64) containing a downstream portion of the through-bore. The two body parts are joined together to register the downstream portion of the through-bore as a continuation of the upstream portion at respective confronting faces of the two body parts, capturing bearing assemblies (94, 96) of a throttle mechanism (92) between the confronting faces to thereby journal the shaft on opposite wall portions of the throttle body. A gasket (116) is disposed between the confronting faces to circumferentially seal the through-bore, including sealing between the bearing assemblies and the confronting face of the first throttle body part.
