Abstract
There is disclosed a slide type exhaust brake system including a housing accommodating a valve member formed with a plurality of exhaust pressure adjusting holes and having its intermediate beam wall formed with an exhaust pressure escape hole, and a piston rod to which an auxiliary valve mechanism composed of a support frame and a liner is locked. The end portions, bent upwards, of the liner are laid along the peripheral wall portions of the frame to prevent the exhaust gas from escaping from the adjusting holes, thereby eliminating an incipient delay in braking. The liner closes the exhaust pressure adjusting holes when closing an exhaust passageway by the valve member which is at the same time thrust forwards. When opening the exhaust passageway, the liner opens the adjusting holes, while the valve member is moved backwards. The liner surface is also formed with at least one through-hole. This arrangement is combined with an effect of enlarged area of the adjusting holes to cause a sufficient drop in exhaust pressure.
