Abstract

The exhaust conduit (34) of an internal combustion engine, for example a diesel engine, includes an exhaust pressure governor valve (14, 33) that serves to create and control, especially for engine braking purposes, a back pressure in the conduit (34). The valve (14, 33) is characterised in that it comprises a pressure control element (20) defining a plurality of flow passageways (23) for the exhaust gas which are configured to cause the gas to expand as it flows through them, and a restriction member (19) operatively associated with the pressure control element (20) for selectively varying the number of the passageways (23) exposed to the gas flow whereby the back pressure generated in the conduit (34) upstream of the valve (14, 33) may be selectively varied.
