The working principle or usage mode of by-pass valve actuator described in the utility model are as follows: the work of turbocharger is former
Reason is pressurizeed again to cylinder using the power of gas is discharged in cylinder, realizes power recovery.Specifically, when cylinder starts work
When making, by-passing valve is in close state, wheel rotation in the fuel gas drive turbine being discharged in cylinder at this time, and turbine
The rotation of middle impeller drives the wheel rotation in coaxial compressor, and the rotation of impeller is so that compressor is external in compressor
Boundary's air is absorbed, and is pipelined in cylinder, is pressurizeed to cylinder, is that the burning of fuel is more abundant.Institute
The air inlet pipe 12 for stating by-pass valve actuator is connected with compressor, and linkage bar assembly 3 is connected to by adjusting set 9 is set to turbine
On the by-passing valve of machine, when inner pressure of air cylinder is excessive, turbine internal lobe wheel speed is improved, and compressor inner impeller high speed is driven to revolve
Turn, and the high speed rotation of compressor impeller, increase compressor internal pressure, due to the air inlet pipe 12 and pressure of by-pass valve actuator
Connection inside contracting machine causes the pressure chamber air pressure in cover assembly 1 synchronous when compressor internal pressure increases to a certain extent
It increases, pushes the downward radial displacement of diaphragm 2, push and its downward radial displacement of close-connected linkage rod end cap 31, drive position

It drives by-passing valve valve mobile, opens by-passing valve.After by-passing valve is opened, turbine interior is connected to outside atmosphere, pressure
It reduces, therefore the wheel speed of turbine interior declines, drive the decline of compressor internal lobe wheel speed, supply that compressor into cylinder
Tolerance is reduced, and is adjusted internal cylinder pressure with this, is prevented cylinder load excessive, realizes voltage-reducing protection function.Work as inner pressure of air cylinder
When reduction, turbine internal lobe wheel speed is reduced, and compressor wheel rotational speed reduces, and reduces compressor internal pressure, due to bypass
It is connected to inside the air inlet pipe 12 of valve actuator and compressor, when compressor internal pressure increases to a certain extent, leads to upper cover
Pressure chamber air pressure in component 1 reduces, and keeps the driving linkage rod end cap 31 of spring 4 mobile to pressure chamber, and then drive and be located at linkage
The adjusting sleeve 9 of 32 bottom end of club shaft is mobile, closes by-passing valve.After by-passing valve is closed, turbine interior and outside atmosphere every
Absolutely, pressure improves, therefore the wheel speed of turbine interior rises, and compressor internal lobe wheel speed is driven to rise, make compressor to
Air demand increases in cylinder, adjusts internal cylinder pressure with this, realizes the pressure process to cylinder.
