Engine brake for diesel IC engine - has operating device with hydraulic piston for decompression in area of TDC with hydraulic piston control line in chamber enclosed by cylinder head and cylinder head hood

摘要

Near the exhaust valve is arranged a separated decompression valve (3) and the path control (9) connected to it is integrated in the housing interior of the IC engine. The control line (10) is located in the chamber enclosed by the cylinder head (1) and the cylinder head hood (2) or in the cylinder head itself. The path control (9) is formed by a slider valve, the control slide of which is longitudinally displaceable and is transferable from an injection position connecting the injection pump with the injection nozzle (6) to an engine brake position connecting the injection pump with the decompression valve (3). USE/ADVANTAGE - Engine brake system for goods vehicle diesel engine which takes up little space and provides durable trouble-free braking.
