Abstract
resumo spoiler de turbilhão de fluxo trata-se de um spoiler de turbilhão de fluxo (100) que inclui um reservatório de óleo (32) em que o fluxo de ar de pressurização (90) se move em torno do reservatório de óleo através de uma cavidade de pressurização de reservatório (71), em que a cavidade tem uma entrada (73), uma chapa circunferencial (101) disposta transversalmente a uma porção da cavidade de pressurização próxima à entrada. a chapa circunferencial está disposta na dita entrada para a dita cavidade de pressurização de reservatório. a chapa circunferencial tem uma pluralidade de aberturas com espaçamento próximo (104). o ar de pressurização tem um componente radial (91) e um componente tangencial (93) em que a chapa circunferencial e a pluralidade de aberturas com espaçamento próximo reduzem substancialmente o componente tangencial do ar de pressurização, e ainda, em que o spoiler de turbilhão inibe a alteração de pressão excessiva no interior da cavidade de pressurização e inibe o vazamento de óleo em vedações (68, 70) adjacentes ao reservatório de óleo.
