Abstract
An exhaust brake unit comprises a case to be inserted into an exhaust gas line, a valve seat located inside the case so as to encircle an exhaust gas passage, a pair of cavities formed on opposite side walls along the exhaust gas passage, a pair of shafts mounted in the respective cavities, and a pair or swing flaps mounted on the respective shafts. Facing flaps open and close the exhaust gas passage through the action of being engaged with the valve seat and disengaged from it. The flaps are connected to an actuating means by way of a linking mechanism which can be variously modified. The flaps may have unequal areas and/or have a time lag between their opening movements to reduce the force and time required to open the flaps.
