Kind of axial limiting pin, which limit to filter screen and strainer retaining ring, is clearly present that structure is complicated, erroneous for installation with fixed mode
Defect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pump discharge feedback variable pumps, which can filter machine oil
In impurity, and structure is simple, easy for installation.
In order to solve the above-mentioned technical problem, present invention employs two kinds of technical solutions arranged side by side, the first technical solution is:
A kind of pump discharge feedback variable pump, including the pump housing and pump cover, the pump housing are equipped with oil inlet and oil outlet, set on the pump housing
There is the feedback oil duct communicated with the oil outlet, the exit of the feedback oil duct on the pump housing is equipped with a counterbore, described heavy
Hole is provided with a net-filter assembly, and the position that the counterbore is corresponded on the pump cover faying face is equipped with a shrinkage pool, the shrinkage pool
Aperture be less than the outer diameter of the net-filter assembly, the oilhole communicated with the shrinkage pool is additionally provided on the pump cover, the oilhole connects
It is connected to pilot valve and/or solenoid valve.
Second of technical solution of the invention is: a kind of pump discharge feedback variable pump, including the pump housing and pump cover, the pump housing
It is equipped with oil inlet and oil outlet, the pump housing is equipped with the feedback oil duct communicated with the oil outlet, anti-on the pump housing
The exit for presenting oil duct is equipped with a counterbore, and the counterbore is provided with a net-filter assembly, corresponds to institute on the pump cover faying face
The position for stating counterbore is equipped with a shrinkage pool, and the aperture of the shrinkage pool is greater than or equal to the outer diameter of the net-filter assembly, the shrinkage pool
Inner wall be equipped with multiple salient points concordant with pump cover faying face, be additionally provided with the oilhole communicated with the shrinkage pool on the pump cover,
The oilhole is connected to pilot valve and/or solenoid valve.
In above two technical solution, by installing net-filter assembly in the counterbore of the pump housing, prevent from machine oil
Granule foreign enters in pilot valve and/or solenoid valve, meanwhile, by the way that shrinkage pool is arranged on pump cover, and be respectively adopted design compared with
Salient point is arranged on shrinkage pool inner wall in small shrinkage pool aperture, and to realize the limit to net-filter assembly, total is simply ingenious,
It is also very convenient for assembling up.
