ABSTRACT:
There is disclosed a slide-type exhaust braking system for applying a braking function to a vehicle by blockading a passageway for an exhaust gas. This system includes an exhaust pressure adjusting hole passageway disposed at a bottom wall portion of a reciprocation passageway of a valve member in a body housing so that the hole passageway leads to a rear passageway. The system further includes an auxiliary valve member disposed at the hole peripheral portion, this auxiliary valve member being biased by springs. The exhaust pressure adjusting hole passageway is closed by pressing the auxiliary valve member with the piston rod and is opened with an upward movement of the piston rod. Impulsive forces acting on the auxiliary valve member are absorbed by shock-absorbing means provided at the tip of the piston rod or by virtue of a double valve structure.
