Abstract

Patente de Invenção para <B>ABAFADOR/DEFLETOR DE LIMPADOR à VáCUO<D>. Um abafador e aparelho defletor de ar combinados para um limpador à vácuo inclui um corpo tendo primeira e segunda extremidades, a primeira extremidade adaptada para ser acoplada a um orifício soprador de um limpador à vácuo. Uma capa apresenta uma primeira extremidade que define uma descarga, e uma segunda extremidade que é acoplada à segunda extremidade do corpo, de modo que o corpo e a capa definem uma passagem para direcionamento de ar do orifício soprador para a descarga. A descarga pode ser geralmente afilada, tal que o ar que flui através da passagem a partir do orifício soprador é restringido. Um dispositivo está situado na passagem para abafamento do som. Em uma concretização, o dispositivo de abafamento de som compreende um divisor que cria câmaras de reflexão de som. Em outra concretização, uma almofada acústica funciona como o dispositivo de abafamento de som.
