Abstract

faces de vedação são submetidas a lubrificação de fluido e baixa fricção em um funcionamento constante, e o vazamento de um fluido vedado e a entrada de poeira nas faces de vedação são impedidos. em uma face de vedação de, pelo menos, uma peça deslizante de um par de peças deslizantes, uma ranhura de geração de pressão dinâmica 10 é forne-cida de modo a ser separada para não comunicar com um lado de fluido vedado e um lado de vazamento por partes de terra em ambas as faces de vedação, entre uma extremidade 10a no lado de vazamento da ranhura de geração de pressão dinâmica 10 e o lado de vazamento, uma ranhura de introdução de fluido 11 que comunica a ranhura de geração de pressão dinâmica 10 e o lado de vazamento é fornecida, e a área de seção transversal da ranhura de introdução de fluido 11 é definida menor do que a área de seção transversal da ranhura de geração de pressão dinâmica 10.
