The present invention relates to apparatus for the preparation and regulation or dosage of a mixture of ?uids especially adapted to theme duction of an explosive mixture for the supply of 2 A ._ a \ 2,296,970 I3 is pushed to the other extremity of its course as is shown in Fig. 3 it clearly appears that the maximum opening of valve I5 is obtained while valve I6 has not moved. It is also clear that in accordance with any intermediary location of the pin II’ in the regulating link 9, there will be a corresponding ratio between the two valve movements. Thus the flow of air can be regu lated to form a combustible mixture ,of appro priate proportions at all conditions of operation of an engine and this can be done in the case of a vehicle While the vehicle is in motion and fromv the driver's seat. The arrangement describedwith reference to the drawings can be utilised to obtain a homog eneous mixture of liquid with gas as for example a mixture of air and petrol or heavy oil for ‘petrol? driven or Diesel engines and can replace the usual carburetters for engines of all descriptions.’ The arrangement also notably improves upon the results obtained with existing mixers especially with regardto the intimate nature of the mixture on which depends the thermo-dynamic ei?ciency of the explosion. . I claim: 1. A centrifugal mixer for fluids comprising a centrifugal rotor, conduits for supplying the ?uid components to the rotor, valves controlling the said conduits, means for controlling one of said valves, said means comprising a slotted link, means for controlling the other of said valves, said means comprising a link adjustable in the slot of the ?rst link, and means for adjusting the be position of said second link to vary the propor tional openings of the two valves without effecting operation of the ?rst link. 2. A centrifugal mixer for ?uids for use for example in the preparation and supply of an explosive mixture comprising a centrifugal rotor, conduits for supplying the ?uid components to the rotor, valves controlling the said conduits, means to vary the ratio of the openings of the valves, and means coupling the valves to a slotted link, said link having two independent controls whereby the amount of mixture supplied and the relative proportioning of the components may be separately adjusted.
