Abstract

válvula amortecedora seletiva à frequência, amortecedor de choque, e pistão para uso em um amortecedor de choques uma válvula amortecedora seletiva à frequência compreende um canal de fluxo controlado para prover uma conexão fluida entre uma primeira e uma segunda laterais da válvula; uma montagem de válvula controlada no canal de fluxo controlado; uma estrutura de válvula móvel que atua sobre a montagem de válvula controlada de modo a permitir a alteração de uma resistência ao fluxo; e uma câmara de volume variável, a estrutura de válvula móvel interagindo com a câmara de volume variável de modo que o movimento da estrutura de válvula móvel e uma alteração no volume da câmara de volume variável estejam inter-relacionados. a câmara de volume variável compreende uma abertura de saída, em operação, a jusante da montagem de válvula controlada e não compreende uma abertura a montante da montagem de válvula controlada em relação a um fluxo de fluido controlado no canal de fluxo controlado, a abertura de saída provendo uma resistência ao fluxo. uma pressão de fluido a montante da montagem de válvula controlada em relação ao fluxo de fluido controlado atua sobre a estrutura de válvula móvel de modo a induzir uma força sobre o membro de válvula móvel em uma direção para reduzir um volume da câmara de volume variável por meio do fluxo de fluido desde a câmara de volume variável através da abertura de saída.
