Abstract
Abstract The regulating device includes an active element, sensitive to the speed of rotation of the engine, an adjusting element for the flow of fuel per revolution connected to the active element, a sleeve connected flexibly to the active element and a linking mechanism attached on the active element, the sleeve and the adjusting element. Means for the setting of several values of the flow include a member provided with two inclined ramps and stop means provided with two ramps complementary to the preceding ramps. The regulating device may be of ''''any speed'''' or of the ''''mini-maxi'''' type. It can include control means which can be servocoupled to a parameter such as the density of the fuel used by the engine.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
218 words
Regulating device for the fuel flow per revolution of an internal combustion engine comprising an active element adapted to be displaced in a rectilinear direction from an initial position to a displaced position as a function of the speed of rotation of the engine, fuel flow adjustment means for the flow of fuel per revolution, connected to the active element, first elastic means constituted by a spring element urging said active element to said initial position, a rod substantially parallel to said rectilinear direction on which said elastic means is mounted, a support to which said rod is fixed so that its position along said rectilinear direction is adjustable, which enables adjustment of the flow of fuel per revolution, said device comprising, setting means for at least two set values of the flow per revolution mounted on the rod and including a member provided with at least one first inclined ramp, stop means mounted on said support and including at least one second inclined ramp complementary to said first ramp, and second elastic means urging towards one another said setting means and said stop means, the assembly being such that the cooperation of said ramps, on rotation of said member with respect to said support, causes a displacement of the rod and a variation of said set value.

Regulating device for the fuel flow per revolution of an internal combustion engine comprising an active element adapted to be displaced in a rectilinear direction from an initial position to a displaced position as a function of the speed of rotation of the engine, fuel flow adjustment means for the flow of fuel per revolution, connected to the active element, first elastic means constituted by a spring element urging said active element to said initial position, a rod substantially parallel to said rectilinear direction on which said elastic means is mounted, a support to which said rod is fixed so that its position along said rectilinear direction is adjustable, which enables adjustment of the flow of fuel per revolution, said device comprising, setting means for at least two set values of the flow per revolution mounted on the rod and including a member provided with at least one first inclined ramp, stop means mounted on said support and including at least one second inclined ramp complementary to said first ramp, and second elastic means urging towards one another said setting means and said stop means, the assembly being such that the cooperation of said ramps, on rotation of said member with respect to said support, causes a displacement of the rod and a variation of said set value.
Claim 3
Dependent Claim
15 words
Regulating device according to claim 1, wherein said device is of the ''''any speed'''' type.
Claim 4
Dependent Claim
14 words
Regulating device according to claim 1, wherein said device is of the ''''mini-maxi'''' type.
Claim 5
Dependent Claim
69 words
Regulating device according to claim 1, comprising control means for said member adapted to cause it to turn and to hold it in positions as close to one another as desired and for which the said inclined ramps cooperate, so that the rod can occupy longitudinal adjustment positions as close to one another as desired and the variations in the said value of the flow per revolution are continuous.
Claim 6
Dependent Claim
20 words
Regulating device according to claim 1, wherein said member is constituted by a nut including two diametrically opposite inclined ramps.
Claim 7
Dependent Claim
15 words
Regulating device according to claim 5 wherein said nut is provided with a control lever.
Claim 8
Dependent Claim
38 words
Regulating device according to claim 4 wherein said member is constituted by a nut including two diametrically opposite inclined ramps, said nut being provided with a control lever and each inclined ramp extends substantially over a semi-circular arc.
Claim 9
Dependent Claim
68 words
Regulating device according to claim 4, wherein said member is constituted by a nut including two diametrically opposite inclined ramps, said nut being provided with said control means and said control means comprise a lever, and a toothed wheel which meshes with a rack, this latter being mechanically connected to the lever of the said nut, so that longitudinal displacements of the rack cause rotation of said member.
Claim 10
Dependent Claim
21 words
Regulating device according to claim 1, arranged so that the set values of the flow are discontinuous and finite in number.
Claim 11
Dependent Claim
82 words
Regulating device according to claim 9, wherein said nut is provided with a control lever and the surfaces of said nut and of said stop means which co-operate to maintain the nut in a predetermined position are perpendicular to said rectilinear direction, so that the co-operation of the inclined ramps only takes place at the moment of passage from the predetermined position of the nut to another, said passage being actuated by a pull-rod connected mechanically to the lever of the nut.
Claim 12
Dependent Claim
32 words
Regulating device according to claim 1, wherein said control means comprise servocoupling means, phase-locked to a parameter, so that the longitudinal position of the rod depends on the value of said parameter.
Claim 13
Dependent Claim
19 words
Regulating device according to claim 11, wherein said parameter is the density of the fuel used by the engine.
