Abstract

"APERFEIçOAMENTO EM MOTOR DE COMBUSTãO INTERNA COM PISTãO ROTATIVO". O aperfeiçoamento em motor de combustão interna com êmbolo rotativo compreende um rotor (1), uma carcaça (2) com tampas (3), um anel separador do rotor (4) e um eixo de cames (5). O rotor (1) apresenta a forma de um tubo achatado, cuja seção transversal é de um círculo alongado, melhor definido como um perfil epitrocoidal. A carcaça (2) possui a forma externa de um cilindro com uma cavidade interna (21) que é dividida em três câmaras de trabalho (22), cada uma com formato de um segmento de cilindro, que são intercaladas por três lóbulos (23). As tampas do motor (3) apresentam uma abertura central (31), onde se acopla um anel separador (4) dotado de uma engrenagem pinhão (41) que guia a rotação do rotor (1). As tampas (3) ainda possuem três janelas alongadas (33) para admissão dos gases combustíveis e para escape dos gases de combustão. O anel separador (4) faz a ligação entre o eixo de cames (5) e o rotor (1), permitindo que o rotor (1) seja oco. Em um dos lados, o anel separador (4) possui uma engrenagem pinhão (41) que se acopla na coroa dentada (32) da tampa do motor (3). A montagem entre o anel separador (4) e o rotor (1) é feita por interferência. Um sistema de vedação entre as câmaras (22) e o rotor (1) impedem o escapamento lateral dos gases da combustão de uma câmara para a outra, tendo em vista que as pressões em cada uma delas se altera na medida em que o rotor (1) gira. O sistema de vedação consiste em uma haste (24) encaixada em uma sede posicionada no vértice do lóbulo (23) da carcaça (2), que define as extremidades da câmaras (22). Opcionalmente, o motor pode apresentar um segundo estator interno (7) que possui a forma de um prisma triangular com paredes arqueadas para fora, formando três lóbulos em ângulo, que ao girar define, simultaneamente, câmaras internas (8), dobrando a potência do motor."IMPROVEMENT IN INTERNAL COMBUSTION ENGINE WITH ROTATING PISTON". The development in a rotary piston internal combustion engine comprises a rotor (1), a housing (2) with caps (3), a rotor separating ring (4) and a camshaft (5). The rotor (1) has the shape of a flattened tube, whose cross section is of an elongated circle, better defined as an epitrocoidal profile. The housing (2) has the outer shape of a cylinder with an inner cavity (21) which is divided into three working chambers (22), each shaped like a cylinder segment, which are interspersed by three lobes (23). . The engine covers (3) have a central opening (31) where a separating ring (4) is coupled with a pinion gear (41) guiding the rotation of the rotor (1). The lids (3) also have three elongated windows (33) for fuel gas inlet and flue gas exhaust. The separator ring (4) connects the camshaft (5) and the rotor (1), allowing the rotor (1) to be hollow. On one side, the splitter ring (4) has a pinion gear (41) that engages with the gear cover (32) of the engine cover (3). Mounting between the separator ring (4) and the rotor (1) is by interference. A sealing system between the chambers (22) and the rotor (1) prevents the lateral exhaust of the combustion gases from one chamber to the other, since the pressures in each chamber change as the rotor ( 1) turns. The sealing system consists of a rod (24) seated in a seat positioned at the apex of the lobe (23) of the housing (2), which defines the ends of the chambers (22). Optionally, the motor may have a second internal stator (7) which is in the form of a triangular prism with outwardly arched walls forming three angled lobes which, while rotating, simultaneously defines internal chambers (8), doubling the power of the motor. motor.
