Summary of the invention
The purpose of this utility model provides a kind of oil spraying device of diesel oil engine assembly oil inlet hole high pressure oil filtrating equipment, characteristics are: simple and reasonable, can effectively purify elimination impurity to high pressure oil, prevent the wearing and tearing of oil sprayer oil nozzle idol part, make the high pressure oil sufficient combustion, improve combustion efficiency, save power, guarantee the motor proper functioning, reduce environmental pollution, and high pressure oil is played certain resistance reverse action, make diesel engine work more steady.Can extensively on the oil sprayer oil inlet hole of automobile, the various models of tractor diesel engine, install and use.
Main technical schemes of the present utility model is: a kind of oil spraying device of diesel oil engine assembly oil inlet hole high pressure oil filtrating equipment, comprise oil inlet hole, and it is characterized in that in oil inlet hole, being provided with high pressure oil and cross filter core.
The described filter core the best of crossing is a filtration nook closing member, and this filtration nook closing member is provided with the position structure that cooperates with the oil inlet hole inwall, and is provided with the filtration slit between filtration nook closing member and oil inlet hole inwall.Cross filter core and also can be porous material core etc.
The preferred construction of described filtration nook closing member is: filter the oil-feed end of nook closing member and fuel-displaced end all with oil inlet hole inwall secure fit, and the oil-feed end of filtering nook closing member is provided with oil-feed tank, the fuel-displaced end of filtering nook closing member is provided with out oil groove, the diameter at the middle part of filtration nook closing member is less than the oil inlet hole diameter, form the oil strain gap therebetween, and oil-feed tank and go out oil groove and all be connected with the oil strain gap the one side relative with oil-feed tank that oil groove is located at the filtration nook closing member.Be that oil-feed tank and going out has a buffering to filter wall between oil groove.Going out oil groove also can be located at and filter nook closing member and same one side oil-feed tank.
Described oil strain gap is that 0.05 ~ 0.2mm is good.
Described oil-feed tank extends to the middle and lower part of filtering nook closing member, and going out oil groove, to extend to the middle and upper part of filtering nook closing member be good.Be oil-feed tank and go out oil groove and laterally link to each other, can increase the buffering voltage regulation result by filtering wall.
Described oil-feed tank can be more than 2, go out oil groove also for identical more than 2, each oil-feed tank and go out oil groove in radially corresponding interlaced arrangement.Oil-feed tank and go out oil groove and also can be 1.
Described oil-feed tank and go out oil groove and be 3 for good is arranged in 120 ° of staggered forks of correspondences radially.
Characteristics of the present utility model are: can effectively purify high pressure oil, elimination impurity, prevent the wearing and tearing of oil sprayer oil nozzle idol part, make the high pressure oil sufficient combustion, fuel-economizing improves combustion efficiency, save power, guarantee the motor proper functioning, reduced the discharging of CO, SO2, NO2 and particulate, reduce environmental pollution; And can produce certain or bigger counterseal phenomenon (effect) to high pressure oil, unlikely even part and the firing chamber of flinging of oil makes oil pressure stable, reduces detonation, reduces pinking, makes diesel engine work steady, reduces vibration, reduces noise, improves the working life of diesel engine.Can extensively on the oil sprayer oil inlet hole (comprising the straight formula oil inlet hole of staggered form oil inlet hole or one) of automobile, the various models of tractor diesel engine, install and use.Especially steady, the purification to the single cylinder high-pressure oil feed is an innovation greatly.
Be described further below in conjunction with embodiment, but not as to qualification of the present utility model.
