Abstract
The invention discloses an oil filter assembly capable of automatically adjusting oil pressure. According to the structure of the oil filter assembly capable of automatically adjusting the oil pressure, an oil inlet is formed in the right lower side of an oil filter base, and a pressure relief oil port is formed in the upper side of the oil inlet. An oil outlet for filtered oil is formed in the left side of the oil inlet of the oil filter base, an oil filter tank is arranged in the middle of the oil filter base and communicated with an oil inlet of an oil filter, and the filtered oil flows back to an engine body from an oil outlet of the oil filter tank. A pressure adjustment valve is arranged on the oil inlet of the oil filter base, cyclic oil of the engine body of an engine enters the oil filter to be filtered while no external pipeline is arranged, and the cyclic oil of the engine body of the engine enters the oil filter directly through an internal oil way of the oil filter base. The oil filter base is very compact in structure and is characterized in that a special external pipeline arranged when the cyclic oil enters the oil filter is omitted. Due to the arrangement of the pressure adjustment valve, the pressure of oil in the lubricating oil circulating system of the engine can be stabilized within a certain range, safety of the oil pipeline system of the engine is guaranteed, and oil cut-off accidents will not happen to all lubricating parts.
Description
Technical field
The invention belongs to engine accessory parts, be specifically related to a kind of oil filter of motor.
Background technique
Oil filter is the requisite parts of motor, because containing a certain amount of colloid, impurity, moisture and additive etc. in machine oil, the effect of oil filter is filtered out by these foreign material, thus to the machine oil that motor each lubricant housings conveying is cleaned.In addition, in engine working process, the grinding between each moving element, will bring in the abrasive dust of metal, air foreign material into and produce machine oil oxide again, this makes again the foreign material in machine oil increase gradually.If machine oil is without filtering, directly bring above-mentioned foreign material into lubricating oil path, so the friction surface of each kinematic pair, the wearing and tearing of part can be accelerated undoubtedly, reduce the working life of motor.But in the work of oil filter while guarantee is filtered, must the engine oil pressure of engine oil gallery.If the oil pressure of oil circuit is too high, oil pipe line will be there is and filter cleaner road breaks, meanwhile, make flow of lubrication excessive because oil pressure is too high and scurry into firing chamber, lubricating oil consumption oil mass being increased, affects engine performance.If therefore can adjust voluntarily the pressure in oil filter, be undoubtedly the difficult problem that each engine production producer urgently will solve.
Summary of the invention
The object of the invention is, propose a kind of can the oil-filter asgine oil conditioner of automatic adjusting machine oil pressure, to ensure the safety that engine operation is run.
For realizing this object the technical solution used in the present invention be: the right lower side of oil filter seat is provided with filler opening, is provided with pressure release hydraulic fluid port on the upside of filler opening.The oil outlet of oil after filter is arranged on the left side of oil filter seat filler opening, and oil filter is arranged on the middle part of oil rectifier seat and is communicated with oil filter filler opening, and the machine oil after filtration returns body from oil filter tank oil outlet.Pressure regulator valve is arranged on the filler opening of oil filter seat, and the ingress engine oil rectifier of engine body circulation machine oil filters and do not arrange external pipeline, is directly completed by the internal oil passages of oil filter seat.
Arrange pressure regulator valve at the filler opening of oil filter seat, when the oil pressure to be filtered from body exceedes specified value, pressure regulator valve is opened, and machine oil is directly by pressure release hydraulic fluid port return engine crankcase.Prevent from motor, occurring pipeline and filter cleaner explosion, also prevent from causing flow excessive because oil pressure is high and scurrying into firing chamber simultaneously, affect engine performance.
The beneficial effect of feature of the present invention and generation is: closely, key is the special external pipeline be provided with when eliminating circulation machine oil ingress engine oil rectifier to the structure of (1) oil filter seat.(2) setting of pressure regulator valve can make the engine oil pressure in engine lubrication oil circulating system be stabilized in certain scope, ensure that the safety of engine oil pipeline system, and makes each lubricating component there will not be oil-break accident.

Embodiment
Structural principle of the present invention to be described further by specific embodiment referring to accompanying drawing.
Can the oil-filter asgine oil conditioner of automatic adjusting machine oil pressure, comprise oil filter seat, oil filter tank (all referred to as engine filter in industry) and pressure regulator valve etc.Its structure is: the right lower side of oil filter seat 1 is provided with filler opening 1-1 (calling oil filter seat filler opening in the following text), is provided with pressure release hydraulic fluid port 1-2 on the upside of filler opening.The oil outlet 1-3 of oil after filter is arranged on the left side of oil filter seat filler opening, and oil filter 2 is arranged on the middle part of oil rectifier seat and is communicated with oil filter filler opening 1-4, and oil filter is fixed by inipple and oil filter seat.Machine oil after filtration returns body (as Fig. 1) from oil filter tank oil outlet 1-5.Pressure regulator valve 3 is arranged on the filler opening of oil filter seat, and the ingress engine oil rectifier of engine body circulation machine oil filters and do not arrange external pipeline, is directly completed by the internal oil passages of oil filter seat.Machine oil before filtration enters in the middle part of the sidewall of oil filter tank, flows out from oil filter tank top.
As embodiment, the distance H1=90.5mm of oil filter seat oil inlet hole and pressure release hydraulic fluid port; The distance H2=34mm of oil filter seat oil inlet hole and oil after filter oil outlet; The distance L1=77.5mm of oil filter tank oil outlet and oil filter seat filler opening; The oil outlet of oil after filter and the distance L2=131mm of oil filter seat filler opening, the aperture D=15mm of oil filter seat filler opening.
Machine oil to be filtered, by the filler opening of body ingress engine filter seat, enters machine filter by internal galleries from engine filter oil inlet hole.Machine oil is from the sidewall ingress engine filter of engine filter tank, by flowing out from the oil outlet of engine filter tank internal upper part after filter element filtering, then through the asphalt channel of engine filter seat inside, return body from the oil outlet of engine filter seat and complete filtration (as Fig. 2).
Before oil filtration, if because causing engine oil pressure too high in certain situation and exceeding specified value, now pressure regulator valve can be opened automatically, and machine oil directly returns crankcase from pressure release hydraulic fluid port.
The working principle of pressure regulator valve is as follows: when engine oil pressure is below specified value, and the pressure of spring pedestal 3-1 is less than the elastic force of pressure adjusting spring 3-2, and pressure regulator valve cuts out (as Fig. 3), the direct ingress engine frit of machine oil.When engine oil pressure exceedes specified value, the pressure of spring pedestal is greater than the elastic force of spring, and spring pedestal moves up, and sealing surface is opened (as Fig. 4), and part machine oil is flowed out by this place, flows back to crankcase by the pressure release hydraulic fluid port of oil filter seat.When pressure is reduced to specified value, spring pedestal is descending, reseals with valve body, completes pressure and regulates.
