Abstract

método e sistema para descompressão de cilindro do motor. um sistema para acionar uma válvula do motor para descomprimir um cilindro do motor para a partida do motor e/ou a frenagem do motor é revelado. o sistema pode incluir um primeiro elemento, tal como um pistão externo, disposto acima de uma válvula do motor, que recebe um pistão interno estendido para dentro de um diâmetro produzido no primeiro elemento. uma ou mais molas podem predispor o pistão interno para uma posição predefinida no primeiro elemento. o pistão interno pode incluir uma superfície inferior que diretamente, ou através de um pino deslizante intermediário, atua uma válvula do motor em resposta à aplicação de pressão do fluido no pistão interno. o pistão interno pode ser usado para descomprimir um cilindro do motor para a partida do motor e/ou para realizar a frenagem do motor.
