Description
Technical field
The invention belongs to engine component, and in particular to a kind of engine oil pump assembly of engine.
Background technology
Lubricating oil pump is the essential part of engine, and the effect of lubricating oil pump is that machine oil is to hair for engine provides machine oil
Motivation has the effect of cooling and lubricating, and machine oil continuously feeds the friction surface of each parts, reduces the friction and wear of part,
Ensure engine work.In engine operation process, charge oil pressure is usually constant, and this just brings some problems,
As engine speed is improved, the oil level for pumping into also increases therewith, and engine oil pressure also increases therewith, it may appear that because of engine oil pressure mistake
It is high and cause engine oil leakage, or even pipeline and cleaner are the problems such as burst.Now needing lubricating oil pump carries out pressure regulation, it is impossible to allow machine oil
Pressure is excessive, and otherwise engine is caused to damage.But regrettably current lubricating oil pump does not have the function of adjustment of oil pressure, often
Because the too high lubricating oil of oil pressure scurries into combustion chamber, in addition to influenceing engine performance because of burning quality, also make lubricating oil oil consumption
Amount increases.General lubricating oil pump is divided into gear type and rotator type, and proposed by the present invention is a kind of rotor-type oil pump assembly.
The content of the invention
The purpose of the present invention is to propose to a kind of engine oil pump assembly with adjustment engine oil pressure, by adjusting engine lubricating oil
The charge oil pressure on road, prevents the failures such as engine oil leakage from occurring.
It is to solve this problem the technology used in the present invention structure：Can adjust automatically engine oil pressure rotor-type oil pump
Assembly, including：Oil pump cover, oil pump casing, outer rotor, internal rotor, power transmission shaft, drive gear and pressure regulator valve etc., pressure regulation
Valve is made up of valve body, bonnet, pressure spring, steel ball and split pin.Side around transmission axis hole on oil pump cover is provided with
Oil inlet and oil input channel；Oil-out and oil road are provided with the opposite side of transmission axis hole.Around transmission on oil pump casing
Axle is provided with internal rotor, and outer rotor is placed in the outside of outer rotor, when internal rotor rotates, drives outer rotor rotation, inner and outer Rotator between cog
Form working chamber.Internal rotor and drive gear are fixed on power transmission shaft using interference fit.Pressure regulator valve is located at oil pump casing
One end.
Outer rotor can be rotated freely in oil pump body, and the two is provided with 4.5mm eccentric throws, because not having eccentric throw internal rotor
Outer rotor can not be driven, oil pocket can not be formed.When the inner rotor rotates, outer rotor rotation is driven, is formed between inner and outer Rotator
4 working chambers (such as Fig. 3).This four working oil chambers are formed in internal rotor rotation process, be it is dynamic (have four depressions with it is outer
Rotor is formed, and is not exist simultaneously).One working chamber from oil inlet turn over when, volume increase, produce vacuum, machine oil is through oil-feed
Mouth suction.Rotor continues to rotate, and when the working chamber is communicated with oil outlet, chamber internal volume reduces, oil pressure is raised, and machine oil is through fuel-displaced
Mouth is extruded.The present invention is provided with pressure regulator valve and relief hole on oil pump body, and when pressure exceedes setting, pressure regulator valve is opened, machine oil
By oil leak hole return engine crankcase, engine oil pressure is reduced, realize the effect of adjustment engine oil pressure.
The features of the present invention and the beneficial effect of generation are：Lubricating oil pump, can while ensureing to provide enough lubricating oils
The engine oil pressure of engine oil gallery is adjusted, the oil pressure for limiting oil circuit is too high, prevent engine oil pressure too high and cause machine
Oil seepage even pipeline and cleaner explosion；Meanwhile, it is also prevented from lubricating oil and excessively scurries into combustion chamber, increase lubricating oil consumption oil mass
Plus, influence engine performance.The fuel pump structure is compact, do not increase the external volume of oil pump casing, it is adaptable to polytype
Engine assembly.

Specific embodiment
Structural principle of the invention is described further below by way of specific embodiment.
Can adjust automatically engine oil pressure rotor-type oil pump assembly, its structure composition is：On oil pump cover 1 around
The side of transmission axis hole is provided with oil inlet 1-1 and oil input channel 1-2；Oil-out 1-3 and fuel-displaced is provided with the opposite side of transmission axis hole
Road 1-4.Internal rotor 4 is provided with around power transmission shaft on oil pump casing 2, outer rotor 3 is placed in the outside of outer rotor, internal rotor rotation
When turning, outer rotor rotation is driven, inner and outer Rotator between cog forms working chamber.Internal rotor and drive gear 7 are fixed using interference fit
On power transmission shaft 5, pressure regulator valve 6 is located at one end of oil pump casing.
Pressure regulator valve is sequentially provided with pressure spring 6-3 and steel ball 6-4 in valve body 6-2, bonnet 6-1 by split pin 6-5 with
Valve body assembling is integrated, and relief hole 6-6 is provided with the spring channels in valve body.
Fuel feed hole and power transmission shaft horizontal range L1=38mm；Vertical distance H1=37.5mm；Oil-feed bore dia D1=25mm；
Oil outlet and power transmission shaft horizontal range L2=15.5mm；Vertical distance H2=53mm；Fuel-displaced bore dia D2=17mm；Transmission axis hole
With pressure regulator valve central horizontal apart from L3=10.5mm；Vertical distance H3=44mm.
When engine runs, internal rotor is driven to rotate counterclockwise by power transmission shaft by drive gear, inner and outer rotors
Between cog forms working chamber.When a certain working chamber is turned over from oil inlet, volume increase, generation vacuum, machine oil are sucked through oil inlet.
When rotor continuation rotation makes working chamber be communicated with oil outlet, chamber internal volume reduces, lifting oil pressure, and high-pressure oil enters through oil outlet
In engine lubrication oil duct, lubrication and the cooling of engine are maintained.If engine speed is lifted, pump oil amount also increases therewith,
Engine oil pressure is further raised, but pressure exceed specified value when, it will be made to be reduced to normal value by pressure regulator valve.
The operation principle of pressure regulator valve is as follows, when engine oil pressure is below setting, suffered by the steel ball below pressure spring
Pressure is less than pressure spring elastic force, and steel ball blocks drain path, and pressure regulator valve is closed (such as Fig. 4), and machine oil directly leads to
Cleaner enters the main oil gallery of engine.When engine oil pressure exceedes setting, oil pressure is more than the elastic force of pressure spring, oil pressure
Steel ball jack-up above drain path, drain path are formed into passage with relief hole, high-pressure oil is flowed back to by relief hole and started
In machine body, so that pressure reduction (such as Fig. 5).When oil pressure is reduced to below specified value, pressure spring presses steel ball will
Drain path is re-closing off, and is achieved in pressure regulation.
The present invention is implemented on CY4102 serial diesel engines, and effect is ideal, has prevented because engine oil pressure is too high
The hidden danger for causing engine to break down, improves engine combustion quality.
