Abstract
A slide type exhaust brake having an exhaust pressure regulating passage provided in that portion of the wall of a housing which defines the bottom of a guide passage for a reciprocating valve member such that the exhaust pressure regulating passage extends from the surface of the bottom wall to an exhaust gas flow passage at the downstream side of the valve member when disposed to close the flow passage. The inlet of the exhaust pressure regulating passage is opened or closed by an exhaust pressure regulating valve provided at the distal end of a piston rod of an air cylinder, the piston rod having the valve member movably engaged therewith, in response to the operation of the valve member for opening or closing the flow passage. By virtue of the above-described arrangement, the presence of the exhaust pressure regulating passage has no effect on the mechanical strength of the valve member, and since the inlet of the exhaust pressure regulating passage is opened or closed by the axial movement of the exhaust pressure regulating valve provided at the distal end of the piston rod, there is no fear of wear. Accordingly, it is possible to ensure the tight seal of the inlet of the exhaust pressure regulating passage when the flow passage is closed. Thus, it is possible to effectively maintain the braking function for a long period of time.
