摘要： The fuel feed device includes a fuel injector controlled by an electromagnetic valve. A metering system has a rotary member adapted to send an energizing signal into the electromagnet during a fraction of each turn of the member. A signal generator is adapted to employ, on each turn of the rotary member, a release signal which lasts during a predetermined and constant fraction of a turn of the rotary member to produce the energizing signal whose duration varies in the same sense as that of the release signal and in the same sense as the degree of opening of an auxiliary throttle member in the intake pipe upstream of the main throttle. The auxiliary throttle opens automatically and progressively in proportion as the flow of air increases. The signal generator may comprise a threshold sensing device for the charge on a condenser fed by switch means controlled by the rotary member. The signal generator may comprise a computing device operated by pulses controlled by the rotary member.

摘要： The device has a main jet for normal operation and an idling circuit, both opening into the intake pipe and provided with calibrated orifices to adjust the richness of the air/fuel mixture. An adjustable throttle enables the idling mixture to be adjusted. The adjustable throttle can be bypassed through a passage to the mixing channel during deceleration. The passage has a closing member actuated by a capsule governed by the suction in the intake and by a member sensitive to the engine''s speed. When the bypass is closed the capsule is connected to atmospheric pressure. The capsule is fixed to an element compensating for altitude.
