Be provided with pipeline 10a in the front end of valve body 10, one of them outlet of three-way valve 9 before pipeline 10a connects, another outlet of front three-way valve 9 is also connected inflow pipeline 8 and oil pump respectively with entrance.
working principle
After engine start, the lubricant oil transported by oil pump is to turbo machine fuel feeding, due to the firm entry into service of motor, the quantity and the pressure that are positioned at the exhaust-gas turbocharger machine oil of lubricating system end are not very high, main valve can not be backed down, bypass oil duct is in closed condition, and the machine oil now come by oil pump all enters pressurized machine, ensures that pressurized machine has enough lubricant oil.
After the pressure of lubricant oil is elevated to certain value, unnecessary machine oil flows to valve body by front three-way valve, first jack-up main valve, and compression main valve spring makes main valve rise.Now lubricant oil enters auxiliary-valve chamber by the central oilhole on base plate, and compression auxiliary-valve spring makes auxiliary-valve close.Final main valve rises to and props up adjustment end cap, closes end cap oilhole.
When main valve be elevated to expose side opening time, lubricant oil just enters oil storage tank by side opening.After machine oil is full of oil storage tank, unnecessary machine oil by oil returning tube through after three-way valve flow back to oil sump.The effect of metering hole prevents too much lubricant oil from flowing back into oil sump by oil returning tube, affects the lubricant oil quantity of turbo machine.
When after engine misses, oil pump fuel cut-off, turbo machine also will continue to operate a period of time, the engine oil pressure now acted on below main valve is 0, main valve moves down under the effect of main valve spring, opens end cap oilhole, and main valve is taken a seat closedown side opening.But the central oilhole in this process on base plate is unimpeded.
Due to oil pump fuel cut-off, the at this moment pressure balance of auxiliary-valve is broken, and the pressure below auxiliary-valve is 0, and auxiliary-valve spring starts to uphold, and under the effect of auxiliary-valve spring, auxiliary-valve is lifted off a seat, and oil circuit is connected.The lubricant oil of oil storage tank, under the effect of self gravitation, by the oil channel hole on the end cap of valve termination, auxiliary-valve, main valve central authorities oilhole, enters front tee union, finally flows to turbo machine.
After the outflow of lubrication oil of oil storage tank, in oil storage tank, space increases, and occurs vacuum, at this moment supplements air by oil returning tube, realize pressure balance, ensures that the lubricant oil of oil storage tank can all flow out.
Main valve spring tension is regulated by adjustment end cap.During precession end cap, main valve spring tension increases, and the pressure that main valve is opened also increases.This end cap has oilhole, and when main valve is opened maximum, close oilhole, when engine stoping operation, main valve is descending, and this oilhole is opened, and ensures that oil storage tank communicates with auxiliary-valve.Auxiliary-valve spring tension is regulated by the quantity adjusting packing ring.
