Abstract

resumo "trava de balancim para controlar atuação de válvula de motor" sistemas e métodos atuadores de válvulas de motor usados para descom-primir um cilindro de motor durante a partida, parada de motor, e para frenagem com sangria são divulgados. um sistema exemplificante pode incluir um braço de balan-cim, montado de modo pivotante sobre um eixo de balancim, e uma estrutura mon-tada adjacente ao braço de balancim numa posição fixa em relação ao braço de ba-lancim. um pistão de trava pode ser disposto, de modo deslizante, entre o braço de balancim e a estrutura. o pistão de trava pode ser seletivamente estendido, para engatar no braço de balancim e na estrutura, para limitar o movimento pivotante do braço de balancim e manter as válvulas de motor numa condição aberta.
