Abstract
"CONJUNTO DE VEDAçãO". Uma vedação para ser alojada em uma gaxeta de vedação em um pistão compreende o componente de vedação primário anular, o componente de vedação secundário anular disposto em sentido radial para dentro do componente de vedação primário, e um par de anéis de sustentação afastados entre si em sentido axial, dispostos em uma relação de afastamento mutuo em sentido axial em lados opostos do componente de vedação primário e tendo partes radiais internas, respectivamente, postas em contato com o componente de vedação primário, de modo a se travarem os anéis de vedação na gaxeta de vedação do pistão.
