Abstract

"VáLVULA BORBOLETA SERVO-ASSISTIDA PARA UM MOTOR DE COMBUSTãO INTERNA PROVIDO DE UM SISTEMA DE REGULAGEM PARA A POSIçãO PARCIALMENTE ABERTA (LIMP-HOME). Uma válvula borboleta servo-assistida (1) para um motor de combustão interna compreendendo um assento de válvula (4), um corpo de borboleta (5) que se engata no assento de válvula (4), um eixo (6) ao qual o corpo de borboleta (5) é chavetado, um atuador elétrico (3) acoplado ao eixo (6), um membro elástico (23) adaptado para exercer um torque sobre o eixo (6) que tende a fazer girar o corpo de borboleta (5) na direção de uma posição "limp-home" e um corpo de apoio (29) que compreende um membro excêntrico (35) que forma uma superfície de apoio para um membro de apoio (28) do corpo elástico (23) a fim de fazer, na posição "limp-home" desejada, a rotação do corpo de borboleta (5) causada pelo corpo elástico (23) na ausência da ação do atuador elétrico (3).
