Description

A kind of machine oil cooler
Technical field
The utility model relates to a kind of engine motor oil cooler, relates in particular to a kind of lube oil cooler for diesel engine with oil filter.
Background technique
At present, the machine oil cooler of diesel engine is to install an oil filter in addition again additional to cool off and filtration mostly, often increases pressure regulator valve and carry out pressure regulation on the body main oil gallery.And oil filter is the independent supply of material, such layout increases the complexity of diesel engine surface structure, influence the overall appearance aesthetic feeling of motor, and when appearing at more renew cartridge easily, originally loss and the pollution easily of the trapped fuel in the filter tank, because of bulky, take certain space simultaneously, influence the layout of other part.And when the slow-speed of revolution, can not rationally control the lubricant oil that flows into secondary oil duct, and guarantee the enough lubricants capacities of main oil gallery.CN2541608Y, CN2751144Y disclose motor with machine oil cooler and filter cleaner composite structure, but application performance particularly functional reliability need further to improve.
Summary of the invention
The technical problems to be solved in the utility model is the defective that overcomes prior art, provides a kind of simple in structure, saves the space, can avoid the modularization lube oil cooler for diesel engine that oil path failure occurs and can control diesel engine oil duct pressure and effectively filter.
The utility model motivation machine oil cooler comprises cooler seat 6, cooler core 1 and oil filter, oil filter directly is screwed in the top of machine oil cooler seat, cooler core 1 is installed and is put on cooler seat 6, lead on cooler core 1 inlet channel on the cooler seat 6 one-way valve 8 is set, one-way valve 8 ingress are provided with oil filter bypass valve 9, the bypass channel that oil filter bypass valve 9 outlet UNICOMs communicate with the oil filter inlet, the secondary oil duct 15 that communicates with main oil gallery 17 is set on the cooler seat 6, and secondary oil duct 15 inlets are provided with secondary oil duct inlet bypass valve 7.
In a kind of concrete structure of the utility model engine motor oil cooler, comprise machine oil cooler core 1 and oil filter 2, oil filter comprises oil filter body and oil filter bypass valve assembly 11 and oil filter core assembly 12, and oil filtration directly is screwed in the top of machine oil cooler seat.Be to seal between oil filter body and oil filter bypass valve assembly 11 and the machine oil cooler seat by screw-threaded coupling and by O RunddichtringO 10.The bottom of oil filter core assembly 12 is longer, and straight cutting is gone into the bottom of machine oil cooler seat 6, and seals by O type circle 13.Adopt the abnormity circle to seal between machine oil cooler seat and the machine oil cooler core.Adopt two kinds of abnormity circles to seal between machine oil cooler seat and the body, by the cooler seat with the plug-in installation of integrated type cooler.The part water route is integrated on the machine oil cooler seat.
A kind of improvement as the utility model engine motor oil cooler, oil filter core assembly 12 is described as follows: the core assembly bottom also has long guide rod, and have O type groove in the bottom, and being used for the sealing of working state, the oil after preventing to filter through filter cleaner is got back to oil sump; When needs more during renew cartridge, when up carrying element kit, just the lubricant oil that still remains in the filter core can have been avoided polluting and waste by the draining road 16 orifice flow oil return drain pans (direction shown in arrow among Fig. 4) of oil filter base bottom.
The work of several valves is used as following introduction in the utility model engine motor oil cooler: the effect of one-way valve 8 is to prevent that the oil of certain pressure from refluxing, and can ensure at slow-speed of revolution low-pressure state main oil gallery to still have lubricant oil to be lubricated.Acting as when machine oil cooler core 1 takes place to stop up of oil filter bypass valve 9 can be realized the oil circuit bypass, and machine oil can obstructed supercooling directly enters oil filter body and oil filter bypass valve assembly 11 filters (direction shown in Fig. 5 arrow); The effect of secondary oil duct bypass valve 7 is oily flows that secondary oil duct 15 is led in control.From the oil that the main oil gallery splitter section is come, by the pressure control of secondary oil duct bypass valve 7, thereby control flows is to the oil mass (shown in Fig. 3 arrow) of secondary oil duct.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, simple in structure, form modularization, help complete machine and arrange.
2, avoid oil path failure; Can effectively guarantee when low oil circuit pressure the lubricants capacity of main oil gallery.
3, save the space, easy to process.
4, can economize on oil, avoid oil duct to pollute.
5, can carry out sealing between machine oil cooler seat and the body effectively, and machine oil cooler
Sealing between seat and the machine oil cooler core prevents to leak.
