Definitions

• the present invention relates to a power amplifier applicable to all types of engines, heat engines whatever the cycle or the mode of obtaining the fuel explosion or their number of cylinders, or any other engine, including hydraulic or electric motors, without any change in their mode of supply of motive power or in the technology concerning their lubrication or cooling; said amplifier being able to be placed both outside said motors, at the outlet of the motor shaft, and inside their casing then forming an integral part of their internal structure.
• each cylinder of an internal combustion engine for example, is transmitted to the operating shaft only by means of a lever arm which transmits the thrust of the engine piston by amplifying it in a notable proportion which depends on the relationship between them of the elements of this lever arm.
• the same heat engine has as many lever arms as it has pistons, said lever arms being contained in the casing modified for this purpose.
• this same power amplifier can be applied to any motor, including the internal combustion engines themselves being coupled outside their casing to the motor shaft itself, the power of which it increases without modifying the speed, as a reducer of any known type would do so.
• Figures 1 and 2 are schematic views in vertical section showing the application of the object of the present invention to a heat engine, in different phases of the cycle.
• Figures 3 and 4 are schematic views in vertical section showing another application in the same type of engine.
• Figures 5 and 6 are schematic views of the principle of the application of the object of the invention to a different type of engine.
• the object of the invention comprises the lever 1 with two arms which bears on the motor housing at 2 in a mobile manner and is articulated to one of its ends at the foot of the connecting rod 3 of the engine piston. Its point of applica tion 4 located at the other end of the lever 1, closer to the fulcrum 2 than is the articulation on the cylinder 3, is articulated on the head of the connecting rod 5 which actuates the engine crankshaft 6.
• a similar result can also be obtained by means of a lever with one arm 7 which bears on the motor frame at 8 in a mobile manner and is articulated at its other end at the foot of the connecting rod 9 of the piston. Its point of application 10 located between the two, closer to its fulcrum 8 than to the connecting rod 9 is articulated on the head of the connecting rod 11 which actuates the engine crankshaft 12.
• a connecting rod 13, corresponding to the expansion rod, is organized on the plate 14 made integral with the output shaft of said motor.
• the lever 15 is articulated on the connecting rod foot 13 which will play the role of "trigger rod", the other end 16 of the lever 15 being articulated on the head of the connecting rod 17 which will play the role of "rotating rod” the Villebrequin 18; the fulcrum 19 of the lever 13 itself being organized in such a way that the length of the secondary arm of the lever 15 is smaller than the length of its primary arm.
• the stroke of the piston may be increased, which results in the reduction of the diameter for the same displacement, hence a reduction in weight and a reduction in wear, as a result of the reduction in stresses due to the smaller piston surface.
• the present invention can be applied to any type of engine, whatever its energy source, and can be introduced into the construction of the engine associated with it when it exists, with a view to increasing the power available to achieve saving energy and reducing mechanical wear.
