초록 ▼

In an engine braking arrangement for an internal combustion engine with an exhaust gas turbocharger including a turbine arranged in the engine exhaust duct and a compressor driven by the turbine and arranged in the engine intake duct, a brake valve disposed in the exhaust duct upstream of the turbine and a pressure relief line extending from the exhaust duct upstream of the turbine rotor to an area downstream of the turbine and including a stop valve, the stop valve is a rotationally adjustable rotary valve operable by an actuating device depending on the intake pressure in the intake duct.

대표청구항 ▼

[ What is claimed is:] [1.]1. An engine braking arrangement for an internal combustion engine having intake and exhaust ducts with an exhaust gas turbocharger including a turbine with a rotor disposed in the exhaust duct so as to be driven by the exhaust gas generated by the internal combustion engine and, arranged in said intake duct, a compressor driven by said turbine, a brake valve disposed in said exhaust duct upstream of said turbine and being adjustable between open and closed positions and a pressure relief line extending from an area of said exhaust duct upstream of said turbine rotor and including a stop valve for opening or closing said pressure relief line, said stop valve being a rotationally adjustable rotary valve which is operable by an actuating device connected to said rotary valve for controlling said rotary valve depending on the intake pressure in said intake duct.
