In other respects the construction of these two carburettors is much alike, and the purpose aimed at similar—viz., to obtain a more sensitively compensated action for different throttle openings> and in supplying the correct proportion of diluent air to form an approximately c onstant mixture over a wide range of speeds. large flexible diaphragm shown in Fig. 23, this exposing a considerable area to the varying depressions caused by difference of suction effect
