As shown in Figure 1, Figure 2 and Figure 3, a kind of regulating valve, the bullet being successively set in valve opening including valve opening and from inside to outside
Spring 1, plunger 2 and blocking 3 offer oil inlet 5, drain tap 4 and feedback hydraulic fluid port 6, the oil inlet 5 and machine oil on the hole wall of valve opening
The high pressure chest of pump is connected to, and drain tap 4 is connected to low pressure chamber, feeds back the feedback oil communication of hydraulic fluid port 6 and main oil gallery, and plunger 2 is whole
In goblet shape, cylindrical portion 2a including inner end, intermediate stem 2b, outboard end round plate 2c, one end peace of spring 1
In cylindrical portion 2a, a transporting room is formed between stem 2b and the hole wall of valve opening, the outside of round plate 2c is equipped with one
The protrusion of blocking 3 can be contradicted, forms a feedback oil pocket between round plate 2c and blocking 3, feedback hydraulic fluid port 6 and feedback oil pocket connect
It is logical.
It needs to propose explanation about aforementioned regulating valve, schematic diagram when Fig. 2 is in close state for regulating valve, in figure
Cylindrical portion 2a blocks oil inlet 5, and the oil liquid in oil inlet 5 cannot be introduced into valve opening, can not between oil inlet 5 and drain tap 4
It is connected to by transporting room, the protrusion on round plate 2c contacts at blocking 3, at this point, the volume of feedback oil pocket is minimum；Fig. 3 is to adjust
The schematic diagram of valve in the open state, spring 1 is compressed in figure, and cylindrical portion 2a opens oil inlet 5, and oil inlet 5 passes through transfer
Room is connected to drain tap 4, the protrusion on round plate 2c with blocking 3 at a distance, at this point, the volume of feedback oil pocket is maximum.
The working principle for the regulating valve that above embodiment provides is as follows: when the oil pressure of main oil gallery is excessive, main oil gallery
Feedback oil pocket can be entered through feedback hydraulic fluid port 6 by feeding back oil, push plunger 2 that the elastic force of spring 1 is overcome to move inward, until cylindrical portion 2a
It is removed from the position for getting lodged in oil inlet 5, so that oil inlet 5 is connected to drain tap 4 by transporting room, at this point, the low pressure of lubricating oil pump
Chamber is connected to high pressure chest, and the oil liquid of slave oil pump out of the mouth discharge is reduced, so that the oil pressure in main oil gallery reduces, conversely, as master
When the oil pressure of oil duct is too small, the spring 1 of regulating valve, which resets, pushes plunger 2 to be displaced outwardly, and cylindrical portion 2a again blocks up oil inlet 5
Firmly, it can not be connected between the oil inlet 5 with drain tap 4 of regulating valve, the oil increasing of slave oil pump out of the mouth discharge, thus main oil
Oil pressure in road increases.
Compared to traditional regulating valve, the main improvement of the regulating valve in present embodiment is the structure of plunger 2, changes
It is in goblet shape that plunger 2 after is whole, the cylindrical portion 2a including inner end, intermediate stem 2b, outboard end round plate
2c, these three components of plunger 2 are the parts of shape rule, are very easy to processing, and be conducive to batch production, and three portions
Connection type between part is also very simple, can be achieved using welding, threaded connection or other conventional connection types, exactly plunger
2 have made above-mentioned simple improvement, can form feedback oil pocket between round plate 2c and blocking 3, open up so as to avoid in blocking 3
Oilhole and feedback oil pocket.It sees on the whole, the structure of the regulating valve in present embodiment is obviously simplified.It requires emphasis
It is that while structure is simplified, the effect of feedback oil pressure is also improved this regulating valve, and the pressure oil of main oil gallery exists
It is very big with the contact surface of round plate 2c after the feedback hydraulic fluid port 6 on valve opening hole wall enters feedback oil pocket, it can effectively push
2 compressed spring 1 of plunger opens oil inlet 5, realizes the effect of feedback regulation oil pressure.
When designing the plunger 2 in present embodiment, stem 2b and the junction of cylindrical portion 2a and round plate 2c are
Bevel structure, during oil liquid in lubricating oil pump flows into drain tap 4 from the oil inlet 5 of above-mentioned regulating valve, oil liquid can be on inclined-plane
It is buffered in structure, so that draining process slowly carries out, can both reduce the pressure oscillation of oil liquid, can also be reduced oily herein
The noise of liquid impact member.
Preferably, protrusion is also in the shape of a rod, and the length of stem 2b is 3 times of the length of protrusion.
Inordinate wear is generated in order to avoid the pump housing (aluminum material) of lubricating oil pump is directly contacted with spring 1, such as Fig. 2 and Fig. 3 institute
Show, spring base 7 can be installed in the bottom of valve opening, one end of spring 1 is mounted in spring base 7.
In regulating valve blocking 3 structure can there are many, the simple hexagonal socket head plug of selecting structure in present embodiment, such as scheme
Be equipped with shown in 2 and Fig. 3, at the aperture of valve opening the circular step to match with the head of the hexagonal socket head plug and with the interior hexagonal
The screw thread that the bar portion of plug screw matches, it is preferable that also place rubber washer 8 on circular step, when installation, the hexagon socket head cap screw
Bar portion passes through rubber washer 8 and screws in valve opening, and the head of hexagonal socket head plug is then fixed on circular step.
Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides
Formula realizes that any obvious replacement is in the protection model of the utility model under the premise of not departing from the technical program design
Within enclosing.
In order to allow those of ordinary skill in the art more easily understand the improvement of the utility model compared with the existing technology it
Place, some attached drawings of the utility model and description have been simplified, and for the sake of clarity, present specification is omitted one
A little other elements, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the interior of the utility model
Hold.
