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 at least one bearing assembly (94) of a throttle mechanism between the confronting faces to thereby journal a throttle shaft (72) on opposite wall portions of the throttle body. The two body parts also contain a by-pass air passage (114). In one form (FIGS. 1 and 2) an idle air control valve (58) associates with the by-pass passage; in another (FIGS. 3 and 4), an electric motor actuator (167) associates with the passage and with the throttle shaft.
