Description
Technical field
A kind of oil filter of multistage filtering is the utility model is related to, relates generally to oil filter field.
Background technology
In engine working process, carbon distribution and gelatinous precipitate, water for being oxidized under metal filings, dust, high temperature etc. are no
It is disconnected to be mixed into lubricating oil.The effect of oil filter is exactly to filter these mechanical admixtures and colloid, protects oily cleaning to be lubricated, is extended
Its useful life.Oil filter should be strong with filtering ability, and circulating resistance is small, the performance such as service life length.When impurity is being filtered
On clear device filter core it is excessive after easily filter core is blocked, currently existing scheme is that a by-passing valve is added on cleaner, in cleaner
By-passing valve is opened after being blocked, and prevents that completely no machine oil from being filtered into each unit with this.But this solution
It is not by the machine of filtering after all although still organic oil enters each unit and is operated after cleaner is blocked
Oil, the infringement to each unit can be very serious, does not have redundant filter structure.
Utility model content
For above the deficiencies in the prior art, the utility model proposes a kind of oil strainer for the multistage filtering for having a redundant filter
Clear device.
To reach above-mentioned purpose, the technical solution of the utility model is：Including housing and conventional filter core, housing includes cylinder
Chamber is provided centrally with oil outlet with upper lid of the cooperation in cylinder chamber upper end, upper lid, and axle center hole and the oil outlet of the conventional filter core connect
It is logical, and axle center hole is coaxially disposed with oil outlet, is provided with fuel feed hole in the excircle of oil outlet, is provided with the downside of the fuel feed hole of upper lid
Check-valves is set, it is characterised in that the lower end of conventional filter core is provided with dividing plate, and the middle part of dividing plate is provided with corresponding with the axle center hole of filter core
Through hole, the lower surface of dividing plate is provided with redundant filter cylinder corresponding with through hole, and the axle center cylinder of the cartridge filter and conventional filter core is coaxial
Set, be provided with standby filter core in the excircle of redundant filter cylinder, piston cylinder ring be cased with standby filter core excircle, in piston cylinder ring
Lower section be provided with spring, the spring is by piston cylinder ring upwards against being provided with some filter bores, the mistake in the excircle of bulkhead through-hole
Filter opening is arranged on the top of piston cylinder ring.
Technical principle of the present utility model is as follows：When work, when conventional filter core is blocked, in engine oil pressure
Under effect, piston cylinder ring will move down, until the upper surface of piston cylinder ring drops to below the upper surface of standby filter core, now
Machine oil is filtered by standby filter core, and the oil duct of the machine oil by filtering internally flows to oil outlet.Usually due to conventional filter
Core does not block, and can not produce pressure and overcome spring force to pull down piston cylinder ring, therefore usually standby filter core will not work
Make, when thering is impurity to block conventional filter core also will not standby filter core remain to normal work.
The beneficial effects of the utility model are as follows：Using this programme can in fact existing frequently-used filter core can not normally altogether when
Standby filter core can replace conventional filter core automatically and work on, and avoid machine oil when conventional filter core blocks not straight by filtering
Connect across filter core and enter each unit, remain to keep certain filter effect.Standby filter core under the action of the spring, can be usually
It is protected not working, it is known that just start working when conventional filter core obstruction.
Further, transitional cylinder section is set in redundant filter cylinder excircle, the transitional cylinder section upper end is fixed on dividing plate lower end, mistake
Cross cylinder section lower end it is corresponding with standby filter core connection, transitional cylinder section can not by machine oil, its act on be when piston cylinder ring slightly towards
Directly standby filter core will not be exposed when lower slider, the cushion space of downward transition is provided for piston cylinder ring.
Further, drain path is additionally provided with the excircle of redundant filter cylinder, the drain path is arranged on redundant filter cylinder
Excircle, when drain path is exposed piston cylinder ring, when standby filter core fuel feeding or can not also be met with time
Obstruction, now starts drain path, and machine oil is directly by drain path across filter core.
Further, typical filter cylinder is provided with the centre of conventional filter core, the upper end of typical filter cylinder connects with upper lid lower surface
Connect, typical filter cylinder is connected with the oil outlet of upper lid, and the lower end of typical filter cylinder and the through hole of dividing plate connect, and typical filter cylinder is
Conventional filter core provides support, improves its bulk strength.
