[008] Visando superar e se diferenciar dos projetos do estado da técnica é que foi desenvolvido o presente "COMPRESSOR DE MEMBRANAS DE DOIS ESTÁGIOS DE BAIXA E MÉDIA PRESSÃO" o qual, no sentido de facilitar a leitura do texto será, a partir de então, citado apenas como "COMPRESSOR".  In order to overcome and differentiate itself from the state-of-the-art designs, the present "MEMBRANES COMPRESSOR OF TWO STAGES OF LOW AND MEDIUM PRESSURE" has been developed, which, in the sense of facilitating the reading of the text, will thereafter be , quoted only as "COMPRESSOR".

[009] A seguir, serão descritos os desenhos os quais serão posteriormente detalhados.  [009] The following will describe the drawings which will be further detailed.

[010] A Fig. 1 mostra o presente "COMPRESSOR" em vista lateral.  [010] Fig. 1 shows the present "COMPRESSOR" in side view.

[011] A Rg. 2 mostra o presente "COMPRESSOR* em vista lateral com corte longitudinal. [012J A Fig. 3 mostra o presente "COMPRESSOR" em um corte transversal do 1o estágio. [011] A Rg. 2 shows the present "COMPRESSOR * in lateral view with longitudinal section. [012J Fig. 3 shows this "COMPRESSOR" in a cross-section of the first stage.

[013] A Rg. 4 mostra o presente "COMPRESSOR" em vista parcial perspectiva com corte transversal do 2o estágio. [013] A Rg. 4 shows this "COMPRESSOR" partial perspective cross-sectional view of the second stage.

[014] De acordo com os desenhos, o "COMPRESSOR" é composto basicamente de uma estrutura composta de eixo de manivelas(l); lóbulo oblongo(2); diafragma de borracha(3); coletor de descarga(4); válvula de descarga do 2o estágio(5); válvula de admissão do 2° estágio(6); anel distribuidor de pressão(7); capa hemisférica do 2° estágio(S); carcaça bipartida do 1° estágio(9); rolete compressor- peristáltico(10); flange do mancai díanteíro(11); polia de acionamento(12); lençol radial de borracha(13); filtro de ar(14); carcaça do 2* estágio(l5) com câmaras hemisféricas(16); câmara toroidal do 1o estágio(17) e tubo de saída(18). [014] According to the drawings, the "COMPRESSOR" is basically composed of a composite crankshaft structure (1); lobe oblong (2); rubber diaphragm (3); discharge manifold (4); discharge valve of the second stage (5); second stage inlet valve (6); pressure distributing ring (7); hemispherical layer of the 2nd stage (S); 1-stage split housing (9); compressor-peristaltic roller (10); flange of the diesole bearing (11); drive pulley (12); radial rubber sheet (13); air filter (14); 2-stage housing (15) with hemispherical chambers (16); the toroidal chamber of the first stage (17) and the exit tube (18).

[015J O funcionamento do presente "COMPRESSOR" dá-se da seguinte forma. O ar é admitido peio filtro(14) e entra na câmara toroidal do 1° estágio(17) onde um lençol radial de borracha(13) é pressionado contra um ponto tangencial na carcaça(9) pelo rolete(10) descentralizado do eixo geométrico pelo virabrequim(l) que, ao girar, provoca um bombeamento peristáWço do ar (como nas máquinas de hemodiálise) para o anel d'istribuidor(7) que, no segundo estágio, insufla o ar dentro das câmaras hemisféricas(16) passando pelas válvulas de admissão(6) situadas sobre a capas hemlsféricas(8), estas estando pressurizadas recebem (uma por vez) o golpe (soco) do lóbulo oblongo(2) nos diafragmas(3) dispersando Q ar através das válvulas de descarga(5) para o anel coletor de descarga(4) até o tubo de saída(18). Há que se acrescentar que o tençol(13) é preso entre os canais de admissão e descarga por um clipe de chapa de aço (não mostrado), assim dividindo o lado aspirante do lado premente. O acionamento é feito através de um motor (não mostrado) que transmite rotação para a polia(12) que aclona o virabrequim(l) mancalizado dentro do flange(11).  [015J The operation of this "COMPRESSOR" is as follows. The air is admitted by the filter 14 and enters the toroidal chamber of the 1st stage 17 where a radial rubber sheet 13 is pressed against a tangential point on the casing 9 by the decentralized roller 10 of the geometrical axis by the crankshaft (1) which, upon rotation, causes a peristaltic pumping of the air (as in hemodialysis machines) to the distributor ring (7) which, in the second stage, blows the air into the hemispherical chambers (16) through the the inlet valves (6) located on the hemispherical layers (8), which are pressurized receive (one at a time) the blow (punch) of the oblong lobe (2) in the diaphragms (3) by dispersing the air through the discharge valves ) to the discharge collector ring (4) to the outlet pipe (18). It should be added that the tenlet 13 is secured between the inlet and outlet channels by a steel sheet clip (not shown), thus dividing the suction side from the pressing side. The drive is driven by a motor (not shown) which transmits rotation to the pulley (12) which hinges the crankshaft (1) which is locked inside the flange (11).

[016J Tomando por base os documentos citados no estado da técnica, chega-se às seguintes conclusões. [017] Em relação ao documento WO20Q9103217 (A1), este se refere a uma bomba de diafragma multiestágios de construção bastante distinta do presente "COMPRESSOR". On the basis of the documents cited in the prior art, the following conclusions are reached. [017] With reference to WO20Q9103217 (A1), this refers to a multistage diaphragm pump of construction quite different from the present "COMPRESSOR".

[018J Em relação ao documento US3,976,395 (A), este se refere a um compressor centrífugo de múltiplos estágios construído também de forma também bastante distinta do presente "COMPRESSOR", no qual um estator é composto de um conjunto de diafragmas interligados com furos cilíndricos dos detentores do labirinto. Assim sendo, como já dito, bastante distinto do presente prqjeto.  Referring to US3,976,395 (A), this refers to a multi-stage centrifugal compressor also constructed in a manner quite different from the present "COMPRESSOR", in which a stator is composed of a set of diaphragms interconnected with holes of the labyrinth holders. Thus, as already said, quite distinct from the present project.

[019] Em relação ao documento US2012100022 (A1), este se refere a uma máquina de diafragma dotada de vários cilindros com peto menos dois diafragmas adonados hidraulicamente. É, portanto, um equipamento que, apesar do funcionamento por diafragmas, mostra-se totalmente distinto em objetivação e construção do presente "COMPRESSOR*.  [019] In relation to US2012100022 (A1), this refers to a diaphragm machine provided with several cylinders with at least two hydraulically attached diaphragms. It is, therefore, an equipment that, despite the diaphragm operation, is totally different in objectification and construction of the present "COMPRESSOR *.

[020] Em relação ao documento WO0127475 (A1), tratasse o mesmo de um compressor de quatro estágios construído de forma bastante distinta do presente "COMPRESSOR", no qual um eixo descentralizado aciòna um rolamento central que vai acionando a cada 90° um eixo com mola que controla através de um diafragma a admissão e a saída de ar. With respect to WO0127475 (A1), it is the same as a four-stage compressor constructed quite differently from the present "COMPRESSOR", in which a decentralized shaft produces a central bearing which drives a shaft 90 ° each time with a spring that controls the intake and the exit of air through a diaphragm.

[021] Em conclusão, podô-se afirmar que o presente "COMPRESSOR [021] In conclusion, it may be stated that this "COMPRESSOR

DE MEMBRANAS DE DOIS ESTÁGIOS DE BAIXA E MÉDIA PRESSÃO", em razão de todas as suas peculiaridades técnicas que o distinguem significativamente em relação ao conteúdo destacado do estado da técnica, tanto do ponto de vista construtivo como do seu funcionamento, reúne totais condições para pleitear a concessão da Patente de Modelo de Utilidade. OF MEMBRANES OF TWO STAGES OF LOW AND MEDIUM PRESSURE ", because of all their technical peculiarities that distinguish it significantly in relation to the outstanding content of the state of the art, both from the constructive point of view as of its operation, meets total conditions to plead the grant of the Utility Model Patent.
