Abstract
LA PRESENTE INVENCION PROVEE UNA CAMARA (20) DE COMBUSTION DE IMPULSOS MODELADA RELATIVAMENTE COMPACTA, LA CUAL REDUCE EFICIENTEMENTE UNA EXPLOSION INDESEABLE Y RUIDO DE COMBUSTION SIN NINGUN SILENCIADOR VOLUMINOSO. EN LA CAMARA DE COMBUSTION DE IMPULSOS DE LA INVENCION, SE GENERA UN SONIDO DE COMPENSACION EN UN CONDUCTO (14) DE ESCAPE SINCRONICAMENTE CON LA EXPLOSION Y COMBUSTION IMPULSIVA. EL SONIDO DE COMPENSACION TIENE UNA PRESION DE SONIDO IDENTICA A LA DEL RUIDO EN EL CONDUCTO DE ESCAPE, PERO UNA FASE OPUESTA A LA DEL RUIDO, POR LO CUAL COMPENSA EFECTIVAMENTE EL RUIDO EN EL CONDUCTO (14) DE ESCAPE Y REDUCE EFICIENTEMENTE EL RUIDO A PARTIR DEL ORIFICIO (15) DE SALIDA DEL ESCAPE.
