Fuel supply apparatus

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 (5c) 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 (J1) is pinched by a first fuel supply body (10) provided with a fuel inflow path (10b) and a first fuel distribution path (10a), and by the first throttle body (1), and the second fuel injection valve (J2) is pinched by a second fuel supply body (11) provided with a second fuel distribution path (11a) and the second throttle body (3), and
• wherein a fuel communicating pipe (16) for communicating of the first fuel distribution path (10a) of said first fuel supply body (10) and the second fuel distribution path (11a) of the second fuel supply body (11) communicates via an adjacent space formed between opposing side surfaces of a left side outer surface (1y) of the first throttle body (1) and a right side outer surface (3y) 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 (1x, 3x) of each of the throttle bodies (1, 3) in a vertical direction thereof.
