The invention belongs to the technical field of internal
combustion engines and relates to a mechanical regulating type
turbine bleeding
system. The mechanical regulating type
turbine bleeding
system comprises a compressor, a
turbine, the engine, a connecting
pipe, a volume chamber, a moving member and an
elastic component, wherein two ends of a first connecting
pipe are communicated with a discharging
pipe of the turbine and the
left wall surface of the volume respectively, the two ends of a second connecting pipe are communicated with a discharging pipe of the engine and the
left wall surface of the volume respectively, the moving member is installed in the volume chamber and connected with the lower wall surface of the volume chamber through the
elastic component. During operation, the moving member can move up and down in the volume chamber. Under a low-speed working condition of the engine, the moving member moves downward, all the discharged air of the engine passes through the turbine, the air intake of the engine is relatively enlarged, and
combustion conditions of cylinders are good; and under a high-speed working condition of the engine, the moving member moves upward, part of the discharged air of the engine directly flows into the discharging pipe of the turbine, the air intake of the engine is relatively reduced, and
detonation pressures of the cylinders are reduced. The mechanical regulating type turbine bleeding
system is reasonable in design, simple in structure and suitable for turbine pressurization systems of engines.
