Abstract

"peça manual dental com mecanismo regulador de pressão". a presente invenção refere-se a uma peça manual dental que possui uma luva de broca, uma seção de cabeça, uma passagem de fornecimento de ar para introduzir o ar comprimido para a seção de cabeça para acionar a luva de broca, e uma passagem de descarga de ar para descarregar o ar comprimido. a passagem de fornecimento de ar inclui um furo traspassante que se estende axialmente através da parte terminal traseira da peça manual e um membro regulador de pressão tubular e um tubo de fornecimento de ar conectado em série entre o furo traspassante e a seção de cabeça. o membro regulador de pressão possui uma abertura para permitir a comunicação com a passagem de descarga de ar e um corpo de válvula anular disposto de modo axialmente deslizável para abrir /fechar a abertura. quando a pressão do ar comprimido que passa através da passagem de fornecimento de ar excede um predeterminado nível, o corpo de válvula é deslizado para abrir a abertura para descarga do ar comprimido para regular a pressão do ar comprimido a ser fornecido à luva de broca.
