Description
Technical field
The utility model relates to engine lubrication system, specifically a kind of net-filter assembly and the net-filter assembly is used
Lubricating oil pump.
Background technique
It all can include usually feedback cavity and feedback oil duct, feedback cavity is position for becoming the vane type lubricating oil pump of discharge capacity
Long and narrow cavity between rotor cavity wall and variable sliding block, feedback oil duct are arranged on pump case, are used for pump discharge or main oil
The pressure oil in road is introduced into feedback cavity, and the oil pressure in feedback cavity acts on variable sliding block, when the oil pressure in feedback cavity is sufficiently large
When, the elastic force of variable spring can be overcome to push variable sliding block mobile, conversely, variable sliding block is then made in the elastic force of variable spring
With lower return, the output displacement that the change of variable slide position can be achieved with lubricating oil pump is variable.
It since feedback cavity is between rotor cavity wall and variable sliding block, and is a long and narrow cavity, and in machine oil
Inevitably there are the particulate matters such as impurity again, after the impurity in machine oil enters in feedback cavity, variable will be caused
Inordinate wear or even clamping stagnation between sliding block and rotor cavity wall, the change of lubricating oil pump insensitive so as to cause the feedback of feedback cavity
Discharge capacity responds not in time.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of net-filter assemblies and one kind to use the net-filter assembly
Lubricating oil pump.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution: a kind of net-filter assembly, is used for machine oil
Pump, the rubber ring including metal shell and in metal shell, the hollow portion of the rubber ring are equipped with strainer, outside the metal
Shell is made of one piece of circular bottom plate and an annular wall, and the circular bottom plate is equipped with through-hole, and the circular bottom plate is located at the ring
The other end of one end of shape wall, the annular wall is equipped with inside turnup structure.
The utility model is about the technical solution of lubricating oil pump: a kind of lubricating oil pump, including pump case, and the pump case is equipped with anti-
Oil duct is presented, the inlet of the feedback oil duct is equipped with net-filter assembly described in the utility model.
As a preferred option, the metal shell of the net-filter assembly is mounted on the pump case in an interference fit
It feeds back at oil-passage inlet.
The beneficial effects of the utility model are: net-filter assembly provided by the utility model includes the rubber of metal shell and the inside
Cushion rubber, this structure can prevent rubber deformation and fix, can be mounted on pump case in an interference fit, by this
The net-filter assembly of kind structure is mounted at the feedback oil-passage inlet of lubricating oil pump, is prevented from the granule foreign in machine oil and is entered instead
It presents intracavitary.
