Embodiment
For making to have a better understanding and awareness structure characteristic of the present invention and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
A kind of oil filter assembly, comprise filter block 1 and filter tank 2, described filter tank 2 is threaded connection bottom filter block 1, filler opening 3, oil outlet 4 and return opening is provided with in described filter block 1, described filter block 1 is provided with fixed plate, described filler opening 3 and oil outlet 4 penetrate fixed plate, and described fixed plate is provided with some stiffening ribs, can ensure that filter cleaner is installed firmly conveniently like this.
Described filler opening 3 is communicated with oil inlet passage 5, described oil outlet 4 is communicated with oil discharge passage 6, described filter tank 2 comprises the shell 7 of upper end open, bypass valve 8 and filter core 9, the opening of described shell 7 is provided with thread plate 10, top and the thread plate 10 of described filter core 9 are conflicted, the bottom of described filter core 9 is connected with bottom filter tank 2 by supported spring 15, oil passageway 11 is formed between described filter core 9 and the madial wall of shell 7, the center-aisle 12 of filter core 9 is communicated with oil passageway 11, described thread plate 10 is provided with the machine oil import 13 be communicated with oil passageway 11, described oil outlet 4 passes through the opening in communication of shell 7 with the center-aisle 12 of filter core 9, bypass valve 8 is arranged in the center-aisle 12 of filter core 9, described bypass valve 8 is provided with Returnning spring 14.
It is inner that machine oil enters filter tank 2 from filler opening 3; flow through oil passageway 11; and pass through the filtration of filter core 9; the contaminant filters such as the dust in machine oil, iron filings are fallen; machine oil after filtration flows through filter core 9 intermediate flow channel, and in final ingress engine filter block 1, and then lubrication; the kinematic pair such as bent axle, connecting rod, camshaft, pressurized machine, piston ring, protection engine component.
After filter core 9 blocks, oil pressure will promote Returnning spring 14, and bypass valve 8 is opened, and excessive machine oil flows directly in oil filter base 1, thus ensure that motor can obtain the sufficient lubrication of machine oil all the time.Filter core 9 is connected in shell 7 by supported spring 15, and under the active force of supported spring 15, filter core 9 can be pressed on thread plate 10 all the time, and this cleaner assembly structural stability is reliable, and each parts are dismantled and upgraded simple and convenient.
Be provided with the joint 16 to downward-extension in the middle of described thread plate 10, described joint 16 is provided with the tapped hole connecting filter block 1, thus realizes strictly being tightly connected of filter tank 2 and filter block 1.
The outlet port of described shell 7 is provided with sealed cover 17, conflict with thread plate 10 bottom described sealed cover 17, described sealed cover 17 is provided with seal groove 18, described seal groove 18 is provided with seal ring 19, described seal ring 19 is connected with seal groove 18 snap-fit, the base area of seal groove 18 is larger, seal groove 18 bottom surface abuts with thread plate 10, stable connection is reliable, good airproof performance, installs seal ring 19, when machine oil is from filter cleaner ingress engine filter block 1 simultaneously in seal groove 18, seal ring 19 can play good sealing effect, prevents leakage of oil.
Described filter core 9 comprises upper cover 20, lower cover 21, filter core main body 22 and is provided with the center tube 23 of oil through, and described filter core main body 22 is conflicted by upper cover 20 and thread plate 10, and described filter core main body 22 is conflicted by lower cover 21 and supported spring 15.
Non-return valve block 24 is provided with between described filter core 9 and thread plate 10, described non-return valve block 24 comprises the ring portion 26 being sheathed on filter core 9 top marginal zone flange 25, the outer side wall of described flange 25 is extended with the spring sheet 27 of band arc, the end of described spring sheet 27 is resisted against the bottom surface of thread plate 10, and described machine oil import 13 aligns with spring sheet 27.After machine oil flows into filter tank 2 from filler opening 3, preferential impact non-return valve block 24, under the impact force of machine oil, non-return valve block 24 stretches, and occurs opening between non-return valve block 24 and thread plate 10, and machine oil is entered in oil passageway 11 by this opening.When machine oil stops supply, non-return valve block 24 again abuts with thread plate 10 under elastic-restoring force, filler opening 3 and oil passageway 11 is separated, can prevent the machine oil in filter tank 2 from refluxing.
The outer surface of described shell 7 is provided with the portion of screwing 28, described in screw horizontal section, portion 28 be regular polygon.The cross section profile of described shell 7 is greater than the cross section profile in the portion of screwing 28.The described horizontal section, portion 28 that screws is equilateral ten quadrilaterals.Owing to being provided with the portion of screwing 28, during mounting casing 7, directly screwing portion 28 turn spanner with adjustable spanner clamping and just can install, because shell wall is thicker, without the need to considering termination intensity, greatly reducing cost.
The working procedure of this oil filter assembly is:
1), after machine oil flows into filter tank 2 from filler opening 3, preferentially can impact non-return valve block 24, under the impact force of machine oil, non-return valve block 24 stretches, occur opening between non-return valve block 24 and thread plate 10, machine oil enters in oil passageway 11 by this opening, and the machine oil in oil passageway 11 flows through filter core 9, by the filtration of filter paper in filter core 9, and enter in the intermediate flow channel of filter core 9, then flow through tapped hole, finally enter
Enter in oil filter base 1, each component of lubricating engine.When machine oil stops supply, non-return valve block 24 again abuts with thread plate 10 under elastic-restoring force, filler opening 3 and oil passageway 11 is separated, can prevent the machine oil in filter tank 2 from refluxing.
2), after long-time use, filter core 9 easily blocks, now machine oil can not flow through from filter core 9, machine oil in oil passageway 11 can get more and more, when machine oil hydraulic is greater than the yield force of Returnning spring 14, Returnning spring 14 can compress, and bypass valve 8 moves under the pressure of machine oil, the direct gap from bypass valve 8 and attachment hole is flowed out by machine oil, direct ingress engine filter block 1.But now the machine oil of flow direction engine is not yet through filter element 9 net filtration, and this machine oil easily causes damage to motor.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and specification; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
