Abstract

sistema de frenagem de motor usando válvula abastecida de mola. a presente invenção se refere a um sistema de frenagem de motor que inclui um trajeto de controle de escape entre um cilíndro do motor e um trajeto de descarga de escape. a válvula de escape tem um elemento de válvula localizado dentro do trajeto, um elemento de válvula operável entre uma posição fechada para fechar o trajeto de controle de escape, correspondendo a uma condição de operação do motor, e uma posição aberta para abrir o trajeto de controle de escape, correspondendo a uma condição de frenagem do motor. uma mola lança um elemento de válvula em direção da posição fechada. um retentor é arranjado para ser posicionar em duas posições de operação, a primeira posição de operação que evita a abertura de um elemento de válvula e a segunda posição de operação que permite a abertura de um elemento de válvula. uma cunha de acionamento é operável para mover entre a primeira posição e a segunda posição para mover o retentor entre as primeira e a segunda posições de operação.
