<p>The fuel feed is varied by an air pressure signal taken from a first and a second compressor connection (21, 22). The connections are joined by a restrictor (23) and a venturi (24) in series. A bellows (18) is subjected to pressure from the second compressor connection (P3) and a second bellows (19) is subject to a vacuum. A second venturi (25) is connected between the first venturi and the restrictor on its outlet side. The electro magnetic valve is excited by the compressor values to decrease the fuel flow. Stops (29, 30) form upper and lower (acceleration and retard) fuel flow limit values.</p> |
