Abstract

APARELHO E PROCESSO PARA CONTROLAR PRESSãO DE EXAUSTãO.São descritos um aparelho e um processo para controlar a pressão de exaustão em um motor de combustão interna (20) . Em uma concretização o aparelho pode compreender um alojamento (110), uma válvula (100) disposta no alojamento (110); um orifício formado na válvula (100) em que o orifício define um percurso de gás através da válvula 9100); e10 um eixo (130) disposto deslizavelmente em um furo formado na válvula (100), o eixo (130) movível entre uma primeira posição, na qual gás é substancialmente evitado de fluir atravésdo orifício, e uma segunda posição em que gás é permitido fluir através do dito orifício. A posição do eixo (130) pode ser seletivamente variada em resposta a uma força de acionamento.
