Abstract

"VáLVULA DE ENTRADA DE AR PARA COMPRESSOR DE AR EM ESPIRAL GIRATóRIO SEM óLEO". é revelada uma montagem de válvula de entrada de ar para um compressor em espiral giratório. O compressor em espiral giratório inclui elementos em espiral estacionário e em órbita que são interengrazados e encaixados para formar pelo menos uma cavidade de compressão em espiral entre os mesmos, um mecanismo de acionamento aciona o elemento em espiral em órbita em uma órbita em torno do elemento em espiral estacionário, e um dispositivo de mancal anti-rotação mantém o elemento em espiral em órbita substancialmente não rotacional com relação ao elemento em espiral estacionário. A montagem de válvula de entrada de ar fornece um gás não comprimido (por exemplo, ar ambiente) ao aparelho de compressão e evita rotação para trás do elemento em espiral em órbita quando termina a energia para o mecanismo de acionamento. A montagem de válvula de entrada de ar inclui um pistão de válvula posicionado dentro de um canal de entrada de ar conduzindo à região de sucção do compressor em espiral giratório, o pistão de válvula tendo uma primeira posição que bloqueia o canal de entrada de ar e uma segunda posição desbloqueando o canal de entrada de ar. Um elemento de haste de válvula é conectado a um alojamento de válvula, o alojamento de válvula encerra uma cavidade de válvula onde o pistão de válvula é localizado, o pistão de válvula atua em conjunto com uma sede de válvula formada no alojamento de válvula, e superfícies de parada são fornecidas no pistão de válvula e haste de válvula para limitar movimento do pistão de válvula em direção à região de sucção do compressor em espiral giratório.
