France, as- Neuilly-sur- Application June 28, 1937, Serial No. 150,836 In France July 9, 1936 1 Claim. (01. is7-1s2) for limiting the maximum speed 01' internal com- I bustion engines, biles of the type provided in the indu the one hand,

The invention has for its principal object so to construct such devices that it is possible to modify,
at will, the speed limit which the engine cannot exceed unless the apparatus is dismantled. According to a principal f eatureof the invention, such regulating devices include means by which it is possible to modify from a distance and at will, the effect of the resilient means op- Posed to the suction.
According to a means are provided which allow the tension or further feature, regulating the tension and the flexibility of the resilient means opposed to the suction to be modified by the longitudinal and/or rotary'movementof a trol and adapted means.
- part capable of being displaced by a remote conto act on the said resilient Another feature consists in interposing in the remote control for the resilient means, supplementary resilient means to modify at the same time the tension and the flexibility of the resilient system thus constituted. v v
A still further feature relates to the resilient means opposing the suction and comprises forming them from a helical spring, certain turnsof which are covered by a sheath having such a thickness (or vseveral successive sheaths having 7 such different thicknesses) that the pitchof the spring between the than that of the turns thus covered is greater non-covered turns. a determined initial tension to the This gives spring, 'the sheath prei'erably being able to slide along the turns in useful length of th by the said sheath.
such a manner thata more or less great e helical spring is ail'ected In order that the invention may be better understood, it will now to the accompanying drawings which be described with-reference are given by way'oi. example'and in which:
' Figs; 1 and 2 show.
carburettor-s with s in longitudinal section, two peed limiting devices conspeed limiting device constructed according to another embodiment of the invention.
The carburettor proper can be constituted in any appropriate manner and the speed limiting device is constituted particularly as already indicated in my pending application S. N, 745,350 filed ,September 22, 1934,'by providing it with a throttling member or butterfly valve I mounted freely and eccentrically on its axis 2 while it is influenced by a spring 3 which tends to move the butterfly valve towards its position of opening by applying it against an abutment moving with the operating member ,of the said butterfly valve. By its eccentric mounting the suction effect, existing in the suction piping 5 of the engine and which varies as a direct function of the speed of this latter, exerts on the two faces of the butterfly valve a differential eil'ect which tends somewhat to close the butterfly valve, when a specified speed is exceeded, in order to restore the speed of the engine to the prescribed value, without the driver having to modify the position of the operating member I.
The spring 3 is coupled, by one of its extremities, to the butterfly valve l and this directly or,
of a threaded socket l3,
preferably, through the intermediary of a small connecting rod 6 bearing on the butterfly ,valve by a removable projection "I, forcibly engaged in its carrier.
In the embodiment according to Fig. 1, thereis engaged between two adjacent turns of the other extremity of the spring, a transverse rod I, which is fixed diametrally in a sleeve 9 in such a way that the said rodl constitutes the holding' element of this other extremity of the said spring. The sleeve 9 is freely engaged in a tubular part I vided laterally on the body H of the carburettor, the larger part of the spring 3 being engaged inthe said tubular part I II. The sleeve 9 bears, by a six-sided flange 12 for example, against the said tubular part l0 through the intermediary witha six-sided flange 10, mounted in a fixed housing pro-' Q spring 3.
load, this speed can running light, for the reason that ll, and the free extremity of the said part l0, When the socket I3 is screwed or unscrewed, the sleeve moves axially in one direction or the other, which permits of modifying the tension of the spring 3 at will. On the other hand, by making the sleeve 3 turn in one direction or the other in the tubular part I0, "by acting on its flange H, the said sleeve isnot moved longitudinally as it is retained by the flange l2 but the transverse rod 8 is moved along the turns of the It is thus possible to increase or diminish the active length and, in consequence, the flexibility of the spring 3, by varying the number of turns which come beyond the retaining element, constituted by the rod 3. By making the sleeve 9 v grooves 22 located such a result to be obtained. In this case the sleeve 9 is eliminated and the extremities of the transverse rod 8 are engaged in helical in the tubular part II). This latter is capable of sliding in its housing provided on the fixed wall ll of the carburettor while being prevented from turning in the said housing by a screw 23 engaged in a longitudinal groove 24 of the part III. This latter. carries, on
and thesocket l3 turn at the same time,'for example with the aid of the cap l5, the number of turns is varied without substantially changing the tension of the spring 3.
The arrangement such as described therefore permits of regulating, by two independent means, the tension and the flexibility of the spring 3 respectively. When the regulation is efiected to give a maximum speed limit, the whole may be covered by a cap l which, by being'engaged on the six-sided flanges l2 and I4, simultanously holds the two regulating members 9 and l3 fixed and assures, at the same time, the fluid-tightness of the carburettor, the said cap l5 being kept in placeby the screwsllii which can, if necessary, be. provided with a lead seal in orderto prevent the dismounting of the cap by unauthorized persons,.for the purpose of modi fying the regulation.
; On the exterior face of the tubular part there is provided a toothed rack I! which meshes with a pinion l8 the axis IQ of which is mounted in the fixed wall II of the carburettor and which is controlled from a distance by any appropriate means, for example by an arm '20 which the driver can move angularly by an appropriate remote control, such as a Bowden cable, an assembly of rods or links articulated between themselves, or otherwise.
T The operatin member of this control is placed within reach of the driver and may be a knob,
handle, or a small lever or otherwise, mounted on the dash-board. By displacing the tubular part jlll by sliding, in consequence of the rotation of the pinion IS, in one direction or the other, there is obtained at the same time the movement by translation of the sleeve 9;which thus modifies the tension of the spring 3 from a distance.
iciosing, at a higher engine speed, in'such' a way that the maximum speed of the, engine is conse- {quently modified. On the other hand, by diminishing the tension of the spring 3, the speed limit of the engine is diminished.
In the embodiment described above, if the 2,100 R. P. M. when running light, but when it is desired, by acting on the remote control,,that
the minimum speed shall be 3,000 R. P. M. at full rise to 3,500 R. P.

L5 is turned its exterior face, a thread 25 on which is enl3 bearing against the free edge of the housing ofthe said part Hi. It results therefrom that if the nut I3 is caused to turn in one direction or the other, a modification of the tension of the spring 3 isobtained, similar to the regulation obtained with the threaded socket 13 of Fig. 1. I y
In order to be able to modify the number of turns and, consequently, the flexibility of the spring 3, the said helical grooves 22 open at the free edge of the tubular part l0 in such a way the transverse,
Leap I5 capable of turning with-respect 'to' the fixed wall ll whilebeing retained by a ring 2'l. In the internal face of the cap I5 longitudinal (or helical) grooves are provided in which the It results therefrom that when the cap through the intermediary of the arm' 20, there is obtained the movement by translation andby rotation, of the rod 8 along the grooves 22, which modifies the tension of the spring 3 and the useful length of this latter, the pitch of the grooves 22' being greater than the pitch of the turns of the spring. x i
A similar result is obtained by the embodiment according to Figs. 3 to 5, in which the rod 8 is engaged transversely in a stem 29 carrying a nut 30 bearing against a part 38 mounted by screws 3E (Fig; 4) on the body it oi the carburettor. By turning the nut 30 in one direction or the other, the tension of the spring 3 can be modi-- fled. By turning the stem 23 in the nut 30, for
example with the aid of a screw-driver which is engaged in its kerfed end 29 the transverse rod 8 is moved along the turns and the number of '1 a push-piece '33 sliding in the part 3!. This minimum speed is regulated for example at 2,000 push-piece is in contact with a spring blade 34,

The nut 30 is moved bya fork 32 integral with inclined with respect to the said push-piece and fixed by one'extremity to a member 35. This The embodiment according to Fig. 2 permits 7 the push-piece 33 through the intermediary .of a
remote control for example a Bowden cable M on which the driver acts. The whole can be giiierefore similar to that with the sleeve 9 of I g.'1.
In order to be able to regulate the tension covered by a cap l5 which assures the fiuidtightnessand which can be sealed.
In order to do away with the regulations indicated above, the remote control Zl forces the member 35 to the end (to the position shown on Fig. 5) in such a way that the push-piece 33.
