Embodiment
In the description of the invention, it is to be understood that the orientation or position relationship of the instruction such as term " interior ", " outer " are
Based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or dark
Show that the device of meaning or element there must be specific orientation, with specific azimuth configuration and operation, thus it is it is not intended that right
The limitation of the present invention.
In addition, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be mechanically connecting or being electrically connected
Connect or the connection of two element internals, can be joined directly together, can also be indirectly connected by intermediary, for
For one of ordinary skill in the art, the concrete meaning of the term can be understood as the case may be.
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and accompanying drawing
Bright, the content that embodiment refers to not is limitation of the invention.
Before specific structure description and explanation is carried out, it is necessary to do brief description to the invention thinking of invention：Hair
A person of good sense is when designing the engine oil pump of a specific model, due to the needs of enging cabin space arrangement, the peace of the lubricating oil pump
Full valve and flow control valve can only be in a very long and narrow spaces, as well known to a person skilled in the art oil pump capacity is adjusted
Section is primarily to solve the problems, such as that oil pressure is too high in engine main oil gallery（On the one hand hypertonia in engine main oil gallery needs
More engine powers are consumed to circulate, some sealing positions is on the other hand also easily caused and is sent out beyond pressure allowable value
Raw seepage）, thus flow control valve uses the feedback oil pressure of main oil gallery, safety valve is then to solve pumping out for lubricating oil pump
The problem of hypertonia of mouth, also the pressure of pump discharge is in general higher than the allowable pressure of main oil gallery, therefore in practice
The Opening pressure of safety valve and flow control valve is also different, and this just considerably increases the difficulty of combination valve design.In addition, just
Referred to Ru foregoing, because the space that the combination valve can take is an elongated shape, the function, again of two valve independence should be realized
Needing to take into account requirement of two valves for releasing and adjusting flow, this devises a combination valve with just courageously breaking through to inventor,
The combination valve shares a valve body, and plunger uses the design of combined plunger, and plunger spring has then used same spring, significantly
The occupancy for reducing volume.
As Figure 1-5, a kind of lubricating oil pump combination valve, including valve body 1, the hollow formation valve pocket of valve body 1, the valve body
1 is provided with oil inlet 2 and drain pan 3, and the oil inlet 2 connects with the pump discharge of lubricating oil pump, the drain pan 3 and engine
Oil sump or the external world are connected, and pilot plunger 4, safe valve element 5 and spring 6, the tune are sequentially provided with from left to right in the valve pocket
The front portion of segmented column plug 4 is additionally provided with the feedback oil pocket 7 of connection engine main oil gallery, and the afterbody of pilot plunger 4 is provided with drain path 8,
The drain path 8 connects oil inlet 2 and its right end face of pilot plunger 4, can be done directly on the oil liquid pressure in oil inlet 2
On safe valve element 5；
When it is described feedback 7 inner fluid hypertonia of oil pocket when, the pilot plunger 4 feedback the inner fluid of oil pocket 7 promotion under to
Move right, the oil inlet 2 connects with drain pan 3, so that the fluid of pump discharge releases to oil sump or the external world；
When the feedback oil pocket 7 inner fluid pressure is normal and pump discharge pressure is too high, the safe valve element 5 is in pump discharge fluid
Individually moved right in the presence of pressure, the oil inlet 2 connects through drain path 8 with drain pan 3, so that the oil of pump discharge
Liquid releases to oil sump or the external world.
As in Figure 2-4, the pilot plunger of combinations thereof valve and safe valve element can have various shapes, and its designing points exists
In the safe sealing surface corresponding with necessarily be formed between valve body or pilot plunger of valve element 5, the sealing surface is ensured in normal condition
Lower drain path is directly truncated with oil leak hole.
Preferably, the middle part of the pilot plunger 4 is annular recess, the annular recess phase of the oil inlet 2 and plunger
Logical, the afterbody of pilot plunger 4 is provided with the safe valve pocket 9 for accommodating safe valve element 5, and the drain path 8 connects annular recess
With safe valve pocket 9, the side wall of the safe valve pocket 9 is provided with some oil leak holes 10 communicated with drain pan 3.
Certainly, can also be not provided with turning into middle part in the middle part of pilot plunger has a structure of annular recess, such as can be with
The inclined oil hole of air shown in Fig. 6 is opened up in pilot plunger 4, after pilot plunger 4 is pushed to ad-hoc location by feedback oil pocket inner fluid,
The oil inlet is turned on oil leak hole by inclined oil hole of air, so as to realize the effect released.
Preferably, the safe valve element is spherical the anterior arc being provided with the cooperation of safe spool face of the safe valve pocket
Shape sealing surface, the safe valve element be able to can move forward and backward in the presence of pressure oil in safety valve intracavitary, so as to control described let out
The break-make of oily passage and drain pan.
Preferably, the safe valve element is cylinder, and the safe valve pocket is also cylindrical cavity, and the safe valve element exists
It is able to can be moved forward and backward in safety valve intracavitary in the presence of pressure oil, so as to control the break-make of the drain path and drain pan.
Further, the both ends of plunger spring 4 are equipped with pad.Pad is set to keep away at the both ends of plunger spring 4
Exempt from due to the problem of pilot plunger frequent movement causes the contact surface abrasion of plunger spring 4 and valve body, practical experience shows, this connects
Contacting surface abrasion easily causes spring breakage, thus can avoid directly wearing valve body to a certain extent using pad, reduces the later stage
The cost of maintenance.
Preferably, the angle position of the annular recess of the pilot plunger 3 is arc transition.
As shown in Figure 2, Figure 3 and Figure 4, when pilot plunger 3 is in frequent movement in the presence of main oil gallery feedback oil pressure, release
Lubricating oil in oil pocket also can frequently shake in oil pocket 6 of releasing, and CFD analog results show that the concussion can cause pump discharge
Oil pressure is unstable, and by the annular recess of pilot plunger 3 be changed to arc transition then can reply reduce its pressure oscillation.
Above-described embodiment is the preferable implementation of the present invention, and in addition, the present invention can be realized with other manner,
Any obviously replaced on the premise of not departing from the technical program design within protection scope of the present invention.
In order to allow those of ordinary skill in the art more easily to understand improvements of the present invention relative to prior art, this
Some accompanying drawings of invention and description have been simplified, and for the sake of clarity, present specification is omitted some other members
Element, those of ordinary skill in the art should be aware that these elements omitted also may make up present disclosure.
