Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of full-flow oil filter, mainly comprise filter block 1 and filter tank 2 two large divisions, be connected by the connecting thread 13 bottom filter block 1 between filter block 1 with filter tank 2, sealed by seal ring between filter block 1 and filter tank 2, described filter block 1 mainly comprises the main oil outlet 11 being arranged on middle part, and be arranged on the filler opening 12 of main oil outlet 11 both sides, described filter tank 2 is primarily of assembly seal ring 21, fixed plate 22, thread plate 23, inner seal ring 24, filter core 28, hold out against spring 211, spring pad 212, housing 25 forms, inner seal ring 24 is arranged between filter core 28 and thread plate 23, holding out against spring 211 is pressed on thread plate 23 by filter core 28 together with inner seal ring 24, described thread plate 23 circumferencial direction is provided with oil inlet hole 231.
Described filter core 28 is primarily of upper end cap assembly 26, filter element filtering cylinder 281, center tube 29, filter core lower end cap 210, and be arranged at filter tank 2 oil outlet 232 place and be integrated in upper end cap assembly 26 bypass valve arrangement composition, upper end cap assembly 26 is connected with filter element filtering cylinder 281, and filter element filtering cylinder 281 is connected with filter core lower end cap 210.
As shown in Figure 5, described bypass valve arrangement is primarily of upper end cap 2611, bypass valve seal ring 262, bypass valve back-up ring 263, bypass valve holds out against spring 265, case of by-pass valve seat 264 forms, upper end cap 2611 is connected with case of by-pass valve seat 264, bypass valve holds out against spring 265 and is pressed on bypass valve seal ring 262 by bypass valve back-up ring 263, bypass valve seal ring 262 and then be forced on upper end cap 2611, upper end cap 2611 center is provided with circular main oil-through hole 261, be positioned at upper end cap 2611 annular region that bypass valve seal ring 262 and upper end cap 2611 contact and along the circumferential direction have bypass oil-through hole, described bypass valve seal ring 262 is ring disk-like structure, central aperture.
Bypass oil-through hole diameter is between 1mm ~ 15mm, and hole count is 1 ~ 20.
Described upper end cap 2611 is shaping by sheet metal with case of by-pass valve seat 264, to rivet or welding manner is connected between upper end cap 2611 with case of by-pass valve seat 264.
Working principle of the present invention is as follows: as shown in Figure 2, when product is in normal working, lubricant oil is flowed into by the filler opening 12 of filter block 1, first flowing through the oil inlet hole 231 filter tank 2 being opened in thread plate 23 circumferencial direction arrives on front side of the filter of filter element filtering cylinder 281, flow through filter element filtering cylinder 281 afterwards, filtered by filter core 28, flowed out from oil outlet 232 by the lubricant oil after filter core 28 filters, enter the oil leab of motor.
As shown in Figure 3, when product occurs increasing suddenly close to life-span end of a period or flow of lubrication, bypass valve seal ring 262 will be washed open by lubricated oil, ensures fuel feeding and the stable rising of oil pressure of lubrication system.At this moment, most of lubricant oil flows into from the filler opening 12 of filter block 1, and the bypass oil-through hole 2611 via upper end cap 2611 flows into the oil outlet 231 of filter tank 2 thread plate 23, then from the lubricating oil path of oil outlet 11 inflow engine of filter block 1.Be integrated in the top load arrangement of upper end cap assembly 26 owing to have employed bypass valve, bypass valve from filter tank 2 oil outlet 232 very close to, effectively shorten the bypass circulation of machine oil filter tank 2; Simultaneously, the bypass valve of top load arrangement can effectively prevent from being tackled by filter core 28 and the objectionable impurities deposited because of the unlatching of bypass valve again lubricated oil wash away out and enter into lubricating oil path, cause objectionable impurities to the secondary pollution of lubricant oil, extend machine oil working life, reduce engine scuffing.
