Balanced Rotary Engine

Abstract

The invention relates to a balanced rotary engine consisting of a rotary engine comprising tangential pistons which improve engine performance, facilitate the lubrication of the engine components, enable the use thereof at high revolutions and condition same for two-stroke operation with full use of the combustion chamber, even with mixtures (diesel cycle) which explode spontaneously upon reaching high compressions with a suitable volume. According to the invention, the components are structured such that (i) the engine can also be self-powered and (ii) the air or mixture is drawn directly from the rear of the cylinder and, subsequently, injected into the combustion chamber of said cylinder or of the cylinder adjacent thereto.

1 . A balanced rotary engine consisting of an explosive engine comprising tangential pistons, a mechanism contained in a single chamber between two mechanically joined circular pieces, rotating in one direction and engaged with a crankshaft with rotation in the opposite direction, wherein the pistons act on the outer arm of a pivoted lever which pivots about a shaft, and with the other arm they carry a crankshaft with a single gudgeon which slides through a groove therein, essentially characterized in that in this mechanism with two or more pistons ( 11  or  21 ), each one acts on a gudgeon ( 14  or  24 ) of the independent crankshaft ( 15  or  25 ), angularly shifted from the other gudgeons the same number of degrees as the cylinders ( 16  or  26 ), and another group of cylinders consisting of the same number thereof can be added in any angular position with respect to the previous ones but which will have the same angular position with respect to one another so that their pistons can act on the same gudgeons as the previous group. This improvement is for the purpose of enabling balancing of the assembly during the rotation thereof.  
   
   
       2 . A balanced rotary engine consisting of an explosive engine comprising tangential pistons, characterized in that the crankshaft and the grooved arms of the pivoted levers actuating the gudgeons are located in a sealed central chamber separated from the rear chambers of each cylinder by the shaft on which the pivoted lever pivots for the purpose of facilitating lubrication of each element and improving the two-stroke operation thereof.  
   
   
       3 . A balanced rotary engine according to claims  1  and  2 , characterized in that it can operate in two or four-stroke cycles.  
   
   
       4 . A balanced rotary engine according to claims  1  and  2 , characterized in that the air or mixture is drawn from the rear chamber of the cylinder in the forward run of the piston through a check valve ( 28 ), compressed during the return thereof and injected into the combustion chamber of the cylinder through a duct ( 29 ) and a valve ( 216 ) controlled by a mechanism with a rocker ( 213 ), a cam ( 214 ) and rod ( 215 ) actuated by the shaft for joining the connecting rod ( 22 ) to the pivoted lever ( 23 ), after the combustion the gases exit to the exterior by a nozzle ( 217 ) made in the rear part of the chamber, in two-stroke operation with controlled or spontaneous explosion.  
   
   
       5 . A balanced rotary engine according to  claim 4 , characterized in that the intake valve ( 216 ) is actuated by gears or a belt and cam or other conventional mechanisms.
