Abstract
Patente de Invenção: <B>''SISTEMA DE ALIMENTAçãO DE GáS PARA UMA PISTOLA DE PULVERIZAçãO POR DETONAçãO"<D>. Este sistema de alimentação de gás para uma pistola de pulverização por detonação não possui válvulas ou dispositivos de vedação mecânicos para alimentar os gases ativos na combustão, ou outros compostos aditivos inertes tais como nitrogênio, argónio, hélio ou similar, tal alimentação dos gases ou compostos sendo realizada direta e separadamente na câmara de detonação (1) através de um conjunto de passagens independentes, uma para o oxidante e pelo menos uma para o combustível, cada passagem consistindo em uma câmara de expansão (8) e um número de condutos de distribuição (9) de seção transversal pequena e/ou comprimento grande. Cada câmara de expansão da passagem (8) é diretamente comunicada com a linha de suprimento correspondente (4) enquanto os condutos de distribuição (9) são convenientemente dispostos de modo que vários pontos de injeção de gás se abrem para dentro da superfície interna da câmara de combustão (1), resultando em uma alimentação contínua e separada de gases em vários pontos o que assegura que a mistura de combustível é feita direta e homogeneamente em uma câmara de combustão (1) e com fluxo suficiente para encher a câmara (1) em cada ciclo de detonação.Invention Patent: <B> '' GAS FEED SYSTEM FOR A DETONATION SPRAY GUN "<D>. This gas supply system for a detonation spray gun has no valves or mechanical sealing devices to power the gases active in combustion, or other inert additive compounds such as nitrogen, argon, helium or similar, such feeding of the gases or compounds being carried out directly and separately in the detonation chamber (1) through a set of independent passages, one for the oxidant and at least one for fuel, each passage consisting of an expansion chamber (8) and a number of distribution ducts (9) of small cross-section and / or large length. Each expansion chamber of the passage (8) is directly communicated with the corresponding supply line (4) while the distribution ducts (9) are conveniently arranged so that several points d and gas injection open into the internal surface of the combustion chamber (1), resulting in a continuous and separate supply of gases at various points which ensures that the fuel mixture is made directly and homogeneously in a combustion chamber ( 1) and with sufficient flow to fill the chamber (1) in each blasting cycle.
