Patent ID: 7028665

Claim:
A fuel supply apparatus comprising: a first intake path extending through a first throttle body and a second intake path extending through a second throttle body, said first intake path and said second intake path being arranged in adjacent in a horizontal direction and arranged so as to be parallel in longitudinal axial lines of the respective intake paths; a first throttle valve and a second throttle valve opening and closing said first and second intake paths, said first and second throttle valves being attached to a throttle valve shaft which is coaxially arranged so as to cut across the respective intake paths; and a first fuel injection valve arranged in one side outer surface of the first throttle body in such a manner that a lower injection hole is inclined toward a center of the first intake path, and a second fuel injection valve arranged in the other side outer surface of the second throttle body in such a manner that a lower injection hole is inclined toward a center of the second intake path, wherein the throttle valve shaft ( 5 ) to which the first and second throttle valves ( 8 , 9 ) are attached, is formed by one shaft and is arranged across toward the second intake path ( 4 ) from the first intake path ( 2 ), and a throttle drum ( 6 ) is fixedly arranged in a left end ( 5 c ) of the throttle valve shaft ( 5 ) protruding from a left side outer surface of the second throttle body ( 3 ), wherein said first fuel injection valve (J 1 ) is pinched by a first fuel supply body ( 10 ) provided with a fuel inflow path ( 10 b ) and a first fuel distribution path ( 10 a ), and by the first throttle body ( 1 ), and the second fuel injection valve (J 2 ) is pinched by a second fuel supply body ( 11 ) provided with a second fuel distribution path ( 11 a ) and the second throttle body ( 3 ), and wherein a fuel communicating pipe ( 16 ) for communicating of the first fuel distribution path ( 10 a ) of said first fuel supply body ( 10 ) and the second fuel distribution path ( 11 a ) of the second fuel supply body ( 11 ) communicates via an adjacent space formed between opposing side surfaces of a left side outer surface ( 1 y ) of the first throttle body ( 1 ) and a right side outer surface ( 3 y ) of the second throttle body ( 3 ) in a horizontal direction thereof, and between an upper side of the throttle valve shaft ( 5 ) and an upper end ( 1 x , 3 x ) of each of the throttle bodies ( 1 , 3 ) in a vertical direction thereof.
