Description
Technical field
The present invention relates to machine oil sendout technical field, more particularly to a kind of engine and the adjustable oil of machine oil sendout
Road structure.
Background technology
Engine motor oil primarily serves the two kinds of effects of lubrication and cooling within the engine at present, and machine oil generally passes through lubricating oil pump
And corresponding oil duct is fed to each position for needing to lubricate and cool down.
Engine lubrication is divided into two parts：The components such as bent axle, major-minor shaft gear shafting lubrication (fuselage of engine) and
The distribution system of the components such as camshaft, rocking arm, valve lubricates (engine head), and 25% He is generally pressed in this two parts traditional technology
75% distribution.As engine speed raises, shafting lubrication changes in demand it is smaller, and distribution system lubrication demand change compared with
Greatly.Distribution system lubrication demand in high speed surges, but due to using the distribution limitation of fixed oil mass, distribution system in traditional technology
Component obtains less than more machine oil in high speed, causes distribution component easy to wear.
In addition, the cooling of engine heat engine part (engine head, cylinder head and cylinder body) is particularly important in high speed.It is sending out
When motivation runs at high speed, it is therefore desirable to which the heat engine part for having more machine oil to wash away engine takes away heat, reduces the heat of engine
Load, but due to using the distribution limitation of fixed oil mass in traditional technology, heat engine part obtains less than more in high speed
Machine oil, the thermic load for causing engine are larger.
The content of the invention
Based on this, it is necessary to provide a kind of engine and the adjustable oil channel structure of machine oil sendout, which can
The oil channel structure of tune can be supplied when oil pressure increases to a certain extent using the stifled movement of limit oil oil to increase oil mass, so as to
Improve the lubricant effect and cooling effect of privileged site；The engine employs above-mentioned oil channel structure, and engine is made to be carried in rotating speed
When height, pump oil amount increase, the oil level of entire engine can reallocate, and lubricating oil is more assigned to greater need for machine
The position of oil, it is possible to reduce abrasion of each moving component in high speed, and improve cooling effect, reduce thermic load, it carries significantly
The service life of high engine.
Its technical solution is as follows：
On the one hand, the application provides a kind of adjustable oil channel structure of machine oil sendout, including the first oil duct and described first
The second oil duct that oil duct is connected to each other and limit oil oil are stifled, the limit oil oil is stifled can automatically reset be arranged at first oil duct with
Between the second oil duct and oily stifled free end of limit oil is set towards the fuel-displaced direction of first oil duct, the limit
Oily oil is stifled to be equipped with the oily passage of limit, and the oil inlet of the oily passage of limit is arranged at the stifled free end of the limit oil oil and with described the
One oil duct communicates, and the oil outlet of the oily passage of limit is communicated with second oil duct；Wherein, when the stifled suffered oil pressure of the limit oil oil
During less than or equal to default oil pressure, first oil duct can only be communicated by the oily passage of the limit with the second oil duct；When the limit
When oily stifled suffered oil pressure is more than the default oil pressure, the limit oil oil is stifled between first oil duct and second oil duct
There are gap, first oil duct is communicated by the oily passage of limit and the gap with the second oil duct；Or when the limit oil oil
When stifled suffered oil pressure is more than the default oil pressure, the limit oil oil is stifled to be equipped with flow increasing passage, and first oil duct passes through the limit
Oily passage and the flow increasing passage are communicated with the second oil duct.
The adjustable oil channel structure of said engine oil sendout in use, using oil pressure pressure under various operating modes variation, utilize
The oily flow realized between the first oil duct and the second oil duct that blocks up of limit oil is adjustable, makes the oil mass being assigned on the second oil duct can basis
The variation of operating mode and be adjusted, meet the lubrication needs and cooling requirement of privileged site.It is specifically, machine oil sendout is adjustable
Oil channel structure be applied to engine in, in low speed, engine oil pressure is not enough to overcome reset force engine, and machine oil can only be from limit
Oily stifled limit oil passage flows through, and entire oil circuit is identical with fixed oil mass distribution at this time, each position oil mass distribution and former mechanism
Equally；When engine speed is increased to specific rotation speeds, the first gallery pressure reaches when can overcome reset force, and machine oil starts to jack up
Limit oil oil is stifled, and after limiting that oil oil is stifled and being jacked up, the limit oil oil is stifled first oil duct and second oil duct between generation
Gap, machine oil pass through simultaneously from the oily passage of limit and gap；Or and the limit oil oil is stifled is equipped with flow increasing passage, first oil duct leads to
It crosses the oily passage of limit and the flow increasing passage is communicated with the second oil duct, can equally increase the lubrication of the second oil duct and the machine of cooling
Oil mass, so as to improve the lubricant effect of privileged site and cooling effect.Further, as the oily oil of limit blocks liter, the first oil duct
Oil pressure declines, and the pump oil amount of lubricating oil pump increases, and the engine power of consumption is reduced, and will improve engine power.
Technical solution is illustrated further below：
In a wherein embodiment, mounting hole, the limit are equipped between first oil duct and second oil duct
Position oil is stifled to be slidably arranged in the mounting hole.
In a wherein embodiment, the inner wall of the mounting hole is equipped with annular seal, and the annular seal is leaned on

Point.
As shown in Figure 1, the adjustable oil channel structure 10 of the machine oil sendout, including the first oil duct 100 and the first oil duct 100
The second oil duct 200 for being connected to each other and limit oil oil stifled 300, limit oil oil stifled 300 can automatically reset be arranged at the first oil duct 100 with
Between the second oil duct 200 and free end 301 of limit oil oil stifled 300 is set towards the fuel-displaced direction of the first oil duct 100, limits oil oil
Stifled 300 are equipped with the oily passage of limit, limit oily passage oil inlet be arranged at limit oil oil stifled 300 free end 301 and with the first oil duct
100 communicate, and the oil outlet for limiting oily passage is communicated with the second oil duct 200；Wherein, when limit oil oil blocks up the first oil is come from suffered by 300
When 100 oil pressure of road is less than or equal to default oil pressure, in the raw, the first oil duct 100 can only be by limiting oily passage for elastic component
It is communicated with the second oil duct 200；When the oil pressure from the first oil duct 100 suffered by limit oil oil stifled 300 is more than default oil pressure, elasticity
Part is compressed, and there are gaps 330, the first oil duct 100 between limit oil oil stifled 300 and the first oil duct 100 and the second oil duct 200 to pass through
The oily passage of limit and gap 330 are communicated with the second oil duct 200；Or when oil pressure suffered by limit oil oil stifled 300 is more than default oil pressure, limit oil
Oil stifled 300 is equipped with flow increasing passage 320, and the first oil duct 100 is communicated by limiting oily passage and flow increasing passage 320 with the second oil duct 200.
The adjustable oil channel structure 10 of said engine oil sendout in use, using oil pressure pressure under various operating modes variation, profit
The flow realized with limit oil oil stifled 300 between first oil duct 100 and the second oil duct 200 is adjustable, makes to be assigned to the second oil duct 200
On oil mass can be adjusted according to the variation of operating mode, meet the lubrication needs and cooling requirement of privileged site.
