Abstract

"MECANISMO DE BOCAL PARA UM DISPENSADOR DO TIPO DE AEROSSOL E PROCESSO PARA GERAR UMA DESCARGA DE FLUIDO DO TIPO DE AEROSSOL". é apresentado um mecanismo de bocal para gerar uma descarga de líquido do tipo de aerossol, mecanismo de bocal que assegura o movimento de líquido em um sentido durante a descarga e tem também um "volume morto" substancialmente zero na ponta do bocal. O mecanismo de bocal inclui uma parte de bocal flexível com uma saída e um canal de fluido, um eixo rígido alojado dentro da parte de bocal flexível, e um alojamento rígido circundando a parte de bocal flexível e expondo a saída. O eixo rígido forma interface com a saída de modo a se formar uma primeira válvula normalmente fechada, de um só sentido, assim como de modo a se definir uma câmara de redemoinho para acumular o líquido que foi canalizado do reservatório de líquido, antes de ser descarregado através da saída. A saída tem uma parede tubular com espessura que diminui ao longo do eixo geométrico de simetria alongado para a saída na direção da ponta da saída. O canal de fluido é posicionado em sentido circunferencial dentro da parte de bocal flexível de modo a se produzir uma ação de redemoinho do líquido distribuído para a câmara de redemoinho. Uma vez que a pressão sobre o líquido de redemoinho atinge uma pressão de limiar suficiente par deformar em sentido radial a parte da saída que forma a primeira válvula normalmente fechada, o líquido na câmara de redemoinho é descarregado através da saída. O mecanismo de bocal é acoplado a uma parte de corpo flexível que tem uma conformação substancialmente tubular e uma espessura de parede que diminui do fundo da parte de corpo na direção da parte de bocal flexível. O eixo rígido alojado dentro das partes de bocal flexíveis estende-se para baixo da parte de corpo flexível, de modo que uma segunda parte do eixo rígido forma interface com a parte de corpo flexível de modo a se formar uma segunda trajetória de comunicação de fluido entre o reservatório de líquido e a câmara de redemoinho.
