Description
Technical field
This utility model is related to cleaner technical field more particularly to a kind of fuel filter pedestal.
Background technology
The flow path of conventional fuel oil filter base intermediate fuel oil is：Fuel oil is entered in pedestal oil-feed oil circuit through oil-in.
Fuel oil is opened and is located at the check valve arranged at oil inlet passage, is entered in pedestal mo(u)ld top half oil pocket by check valve, pedestal mo(u)ld top half oil pocket
In fuel oil flow out from oilhole, fuel oil open be located at the pedestal back side mo(u)ld bottom half oil pocket oil-out at arrange check valve, finally
Enter in cleaner from oil-out, filtered device is flowed out after filtering.
Fuel oil that fuel oil check valve at be impurity is flowed through every time, when the impurity in fuel oil is deposited at check valve
When, check valve will be caused in open mode, check valve sealing function fails, and handss can be caused to play pump not pressurize and cannot pump out
Oil.So will result in vehicle to be again started up difficulty or cannot start, handss need to be re-replaced and make pump, cause handss to beat the use longevity of pump
Life shortens.
For avoiding the failure of non-return valve function, extend the service life that handss make pump, it is necessary to flow through the fuel oil at check valve
For clean fuel oil.Therefore after designing new filter, pump oil pedestal becomes inexorable trend.
Utility model content
The purpose of this utility model is to provide pump oil pedestal after a kind of filter, flows through the fuel oil at check valve
For clean fuel oil, it is to avoid the disabler of check valve, extend the service life that corollary equipment handss make pump.
For achieving the above object, after filter of the present utility model, pump oil pedestal includes base body, base body upper left quarter
It is provided with for beating the upper cylinder that pump coordinates with handss, base body bottom face is provided with the lower round platform for coordinating with filter element；
Epicoele grease chamber, the first check valve and the second check valve, the first check valve and the second check valve point is provided with upper cylinder
It is not connected with epicoele grease chamber；
Fuel feed hole, oil return oil duct and cavity of resorption grease chamber is provided with lower round platform, and oil return oil duct is used for fuel-displaced with external filter element
Oil duct is connected, and cavity of resorption grease chamber is used for being connected with the oil-feed oil duct of external filter element；
The oil inlet passage flowed into for fuel oil is provided with pedestal body, and oil inlet passage forward extends out base body；Oil inlet passage with
Fuel feed hole is connected, and fuel feed hole connects the cavity of resorption grease chamber；
Connection oil duct and oil discharge passage is provided with pedestal body, and oil return oil duct is connected with epicoele grease chamber by the second check valve
Logical, epicoele grease chamber is connected with oil duct is connected by check valve, and connection oil duct is connected with oil discharge passage, and oil discharge passage is to extension
Go out base body.
Oil return oil duct is opened on the center of lower round platform.
After using the present invention, flow through check valve is no longer the filtered fuel oil containing impurity, but through filtration core
The cleaner fuels of impurity are filtered out, and are therefore avoided conventional check valve and the disabler for causing are piled up because firing well cuts, and then
Extend the service life that corollary equipment handss make pump.

Specific embodiment
As shown in figure 1, pump oil pedestal includes that base body 1,1 upper left quarter of base body are provided with after filter of the present utility model
For beating the upper cylinder 11 of pump cooperation with external handss, 1 bottom surface of base body is provided with the lower round platform 12 for coordinating with filter element；
Epicoele grease chamber 9, the first check valve 4 and the second check valve 5 is provided with upper cylinder 11, and the first check valve 4 and second is single
It is connected with epicoele grease chamber 9 to valve 5 respectively；
Fuel feed hole 3, oil return oil duct 7 and cavity of resorption grease chamber 10 is provided with lower round platform 12, and oil return oil duct 7 is used for and external filter element
Fuel-displaced oil duct be connected, cavity of resorption grease chamber 10 be used for be connected with the oil-feed oil duct of external filter element；
The oil inlet passage 2 flowed into for fuel oil is provided with base body 1, and oil inlet passage 2 forward extends out base body 1；Oil-feed is led to
Road 2 is connected with fuel feed hole 3, and fuel feed hole 3 connects the cavity of resorption grease chamber 10；
Connection oil duct 6 and oil discharge passage 8 is provided with base body 1, and oil return oil duct 7 is by the second check valve 5 and epicoele grease chamber 9
It is connected, epicoele grease chamber 9 is connected with oil duct 6 is connected by check valve 4, connection oil duct 6 is connected with oil discharge passage 8, fuel-displaced
