Abstract
1."DISPOSITIVO PURIFICADOR DOS GASES POLUENTES EXPELIDOS PELO ESCAPAMENTO DOS AUTOMóVEIS COM MOTOR DE COMBUSTãO INTERNA". Conformado por um corpo principal desmontável, de forma cilíndrica de secção transversal variável circular e coaxial, com ambas extremidades abertas e comunicadas entre si, onde uma extremidade acopla-se ao escapamento e a outra, comunica-se com o meio ambiente, caracterizado pelo corpo principal estar conformado por duas monopeças encaixadas, a saber: um núcleo e uma cobertura cuja disposição determina no dispositivo, espaços interligados entre si, com o escapamento e com o meio ambiente; onde o núcleo apresenta um setor principal de forma tronco-cónica, sobre cuja superfície apresentam-se orifícios elípticos, apresentando ambas extremidades abertas, e conectado o de diâmetro maior com os dois setores cilíndricos anulares correlativos, tendo este último incorporado meios de ligação com a cobertura, continuando na descrição do núcleo, chega-se a um setor anular cónico para finalizar em um setor em forma de tubo, cuja superfície apresenta cortes paralelos em forma de estrias, configurando uma borda dentada, elementos de ligação com o escapamento; os setores, tronco-cónicos e anular contíguo, estão alojados no interior da cobertura em um trecho cujo diâmetro interno é levemente maior que o diâmetro externo do setor anular que encaixa no mesmo, por sua parte, a cobertura é formada por dois setores ocos cilíndricos e de diferentes diâmetros ligados por um rebordo em talude, estando o núcleo alojado no setor de diâmetro maior, cuja borda possui os meios de ligação com o núcleo; o setor de diâmetro menor é conformado por duas paredes separadas por uma câmara de ar intermediária, apresentando orifícios circulares distribuídos sobre a parede externa.1. "PURIFYING DEVICE FOR POLLUTING GASES EXPELLED BY THE EXHAUST OF AUTOMOBILES WITH INTERNAL COMBUSTION ENGINES". Conformed by a dismountable main body, with a cylindrical shape with variable circular and coaxial cross-section, with both ends open and communicating with each other, where one end connects to the exhaust and the other, communicates with the environment, characterized by the body main being made up of two fitted monoparts, namely: a core and a cover whose disposition determines in the device, spaces interconnected with each other, with the exhaust and with the environment; where the nucleus has a main sector with a trunk-conical shape, on whose surface there are elliptical holes, presenting both open ends, and connecting the larger diameter with the two correlative annular cylindrical sectors, the latter having incorporated means of connection with the cover, continuing in the description of the core, a conical annular sector is reached to end in a sector in the form of a tube, whose surface presents parallel cuts in the form of grooves, configuring a notched edge, connecting elements with the exhaust; the sectors, trunk-conical and contiguous annular, are housed inside the cover in a stretch whose internal diameter is slightly larger than the outer diameter of the annular sector that fits in it, for its part, the cover is formed by two cylindrical hollow sectors and of different diameters connected by a slope edge, the nucleus being housed in the sector of larger diameter, whose edge has the means of connection with the nucleus; the sector of smaller diameter is formed by two walls separated by an intermediate air chamber, with circular holes distributed over the external wall.
