Abstract

"ABSORVEDOR DE CHOQUE DE êMBOLOS DUPLOS". A presente invenção refere-se a um êmbolo de dois estágios que tem uma construção de êmbolo geminado onde um êmbolo produz uma alta força amortecedora e o segundo êmbolo produz uma baixa força amortecedora. Em posições especificadas ao longo do tubo de pressão, passagens de desvio são formadas para permitir o fluxo de fluido em torno do êmbolo de alta força amortecedora para proporcionar uma baixa força amortecedora ou uma marcha suave. Nas áreas do tubo de pressão onde inexistem quaisquer passagens de desvio, o êmbolo de alta força amortecedora proporciona uma alta força amortecedora ou uma marcha estável. Na área do tubo de pressão onde inexistem quaisquer passagens de desvio, o êmbolo de alta força amortecedora e o êmbolo de baixa força amortecedora ambos contribuem para a alta força amortecedora.
