Abstract

resumo do pedido de patente de invenção para: "turbocarregador; e método de operação de turbocarregador". a propensão para vazamento de gás ao redor de uma haste que se estende através de um furo que conecta volumes de pressões diferentes, por exemplo, um alojamento de turbina de turbocarregador e o ar ambiente, é minimizada com a adição de um par de anéis de vedação inclinado por uma pressão do gás para fornecer uma vedação de fuligem e gás contínua. 1/1Summary of Patent Application for: "Turbocharger; and Turbocharger Operation Method". The propensity for gas leakage around a rod extending through a bore that connects different pressure volumes, for example, a turbocharger turbine housing and ambient air, is minimized by the addition of a pair of pressure rings. gasket inclined by a gas pressure to provide a continuous gas and soot seal. 1/1
