<p>PURPOSE:To reduce the size of a braking means through the improvement of the engine brake action by providing a means to close an exhaust throttle valve interlocked to the closing action of an intake throttle valve. CONSTITUTION:An interlocking means comprises a spring 10 pressing an exhaust throttle valve 7 to open position and a lever 11 on an intake throttle valve 6 to press the exhaust throttle valve to close position. A rod 12 has a protrusion 15 to face a through hole 14 formed on a lever 13, said protrusion 15 fitting into the through hole 14 by the closing action of the intake throttle valve 6 to press the lever 13 giving closing pressure to the valve 7 thereby controlling the flow of the exhaust introduced in an exhaust tubine 3 to rapidly reduce the rotation of the turbine and to reduce the supercharging by a compressor 5.</p> |
