In order to achieve the above objectives, the utility model provides following technical scheme：
A kind of filter with relief valve device, including filter core and two end caps, be provided on one of end cap into
Oily passage is provided with oil discharge passage on another end cap, relief valve device is provided in the oil discharge passage.
Preferably, the relief valve device includes：
The spring being arranged in the oil discharge passage；
Flame-arrester vent plug, the flame-arrester vent plug are connected to the spring close to one end of the filter core, and the oil discharge passage is close to institute
The one end for stating filter core is provided with the oil inlet being adapted to the flame-arrester vent plug；
Exhaust cap, the exhaust cap are arranged in the oil discharge passage, and are set close to the oil outlet of the oil discharge passage,
The exhaust cap forms the oriented exhaust cap close to the end of the oil outlet of the oil discharge passage and extends internally hangnail portion, institute
The one end of spring away from the filter core is stated to be extruded in the hangnail portion.
Preferably, the oil inlet of the oil discharge passage is taper.
Preferably, the exhaust cap is in interference fit in the oil discharge passage.
Preferably, the material of the exhaust cap is brass.
It can be seen from the above technical proposal that the filter in the utility model has relief valve device.The one of filter
Oil discharge passage is provided on a end cap, which is arranged in oil discharge passage.In the case where filter core is not blocked,
Oil enters from oil inlet passage in filter, after the filtering of filter core, is discharged from filter core；In the case where filter core is blocked, filter
Core inner pressure increases, and when pressure reaches certain value, relief valve device is opened, and oil is discharged from oil discharge passage.The utility model
In filter can be ensured that fuel-displaced unobstructed and oil pump capacity in the case where filter core is blocked, so as to ensure the steady of engine
Fixed operation.
Description of the drawings
In order to illustrate more clearly of the scheme in the utility model embodiment, will make below to required described in embodiment
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model,
For those skilled in the art, without creative efforts, other be can also be obtained according to these attached drawings
Attached drawing.
Fig. 1 is the structure diagram for the filter with relief valve device that one specific embodiment of the utility model provides.
Wherein, 1 it is exhaust cap, 2 be spring, 3 be flame-arrester vent plug, 4 is filter core.
Specific embodiment
The utility model provides a kind of filter with relief valve device, in the case where filter core is blocked, safety
Valve gear is opened so that oil is discharged, so that it is guaranteed that fuel-displaced unobstructed, it is ensured that oil pump capacity.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model
Embodiment.Embodiment based on the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, shall fall within the protection scope of the present invention.
Attached drawing 1 is refer to, in one specific embodiment of the utility model, the filter with relief valve device includes：Filter
Core 4, two end caps, oil inlet passage, oil discharge passage and relief valve devices.
Oil inlet passage and oil discharge passage are separately positioned on two end caps.Relief valve device is arranged in oil discharge passage.
In the case that filter core 4 is without being blocked, oil enters from oil inlet passage in filter, after the filtering of filter core 4, from 4 row of filter core
Go out；In the case where filter core 4 is blocked, the increase of 4 internal pressure of filter core, when pressure reaches certain value, relief valve device is opened,
Oil is discharged from oil discharge passage.Filter in the present embodiment can be ensured that fuel-displaced unobstructed and be gone out in the case where filter core 4 is blocked
Oil mass, so as to ensure the stable operation of engine.
In one specific embodiment of the utility model, relief valve device specifically includes：Spring 2, flame-arrester vent plug 3 and exhaust cap
1。
Spring 2 is arranged in oil discharge passage.Spring 2 is connected with flame-arrester vent plug 3 close to one end of filter core 4.Oil discharge passage is close
One end of filter core 4 has oil inlet, which coordinates with flame-arrester vent plug 3.It is fuel-displaced logical when flame-arrester vent plug 3 is located on oil inlet
Road is closed.After flame-arrester vent plug 3 leaves oil inlet, oil discharge passage conducting.Exhaust cap 1 is arranged in oil discharge passage, and close
