Title (EN) ALTERNATING ROTARY ENGINE
(FR) MOTEUR ROTATIF ET ALTERNATIF
(PT) MOTOR ROTATIVO E ALTERNATIVO
Abstract:
(EN) The alternating rotary engine is an interactive combination of an alternating system with a rotary system, i.e. one that uses the alternating system for intake and compression and the purely rotary system for power and exhaust, including a doubling of the intake stroke, referred to as phases. The present invention is an engine comprising a seat and a cylindrical extension of this seat, referred to as the core, that houses a system of two alternating pistons designed to supply, as in a conventional compressor, air or mixture (for electronic or carbureted injection respectively) to a rotor that rotates about said core, forming two chambers that each extend along almost half of the perimeter of the rotor, in which the rotor, using fins referred to as gates, generates the power and exhaust strokes, as well as a pre-intake phase and a pre-compression phase, these phases supplying said alternating piston system, by virtue of the geometry of the engine, with previously compressed air or mixture without the need for additional parts such as compressors.
(FR) L'invention concerne un moteur rotatif et alternatif, soit une combinaison interactive d'un système alternatif avec un système rotatif. En d'autres termes, il utilise le système alternatif pour l'admission et la compression, et le système rotatif pur pour l'expansion et l'échappement, y compris un dédoublement du temps d'admission, ce que l'on appelle "phases". La présente invention concerne un moteur comprenant un siège et une extension cylindrique de ce siège, que l'on appelle noyau, recevant intérieurement un système à deux pistons alternatifs ayant pour fonction de fournir, comme un compresseur classique, de l'air ou un mélange (selon injection électronique ou carburation) à un rotor qui tourne autour dudit noyau, formant deux chambres qui s'étendent chacune sur pratiquement la moitié du périmètre du rotor, ledit rotor, à l'aide d'ailettes appelées portes, produisant les temps d'expansion et d'échappement, outre une phase de pré-admission et une autre de pré-compression, ces phases alimentant, du fait de la géométrie même du moteur, ledit système à pistons alternatifs avec de l'air ou un mélange préalablement compressé, aucune partie additionnelle, telle qu'un compresseur, n'étant ainsi nécessaire.
(PT) Motor Rotativo E Alternativo, é uma composição interativa de um sistema alternativo com um sistema rotativo, ou seja, utiliza o sistema alternativo para admitir e comprimir e o sistema rotativo puro para expansão e exaustão incluindo um desdobramento do tempo de admissão denominadas fases. Esta presente invenção é um motor composto de uma sede e de uma extensão cilíndrica desta sede, designada miolo, que abriga em seu interior um sistema de dois pistões alternativos com a função de fornecer, como um compressor convencional, ar ou mistura (conforme injeção eletrônica ou carburada) para um rotor que gira em torno deste dito miolo formando duas câmaras que se estendem cada uma por praticamente metade do perímetro do rotor, rotor esse que, com auxílio de aletas denominadas comportas, produz os tempos de expansão e exaustão, além de uma fase de pré-admissão e outra de pré- compressão, sendo que essas tais fases alimentam, pela própria geometria do motor, o dito sistema de pistões alternativos com ar ou mistura previamente compressionados dispensando quaisquer partes adicionais, como compressores.
