In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawing and specific implementation
The present invention is described in detail for example.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
Self_adaptive adjusting valve as shown in Figure 1, Figure 2, Figure 3, Figure 4 mainly includes shell 1, during the shell 1 is
Cavity body structure is respectively formed left working interface 11, outlet 12 and right working interface 13, the left work on shell 1
Interface 11, right working interface 13 will be connected on the outside of 1 inner cavity of shell and shell 1 respectively, the cross sectional shape of the outlet 12
It is preferred that using rectangular configuration.Check valve is installed in the hollow cavity of shell 1, reset spring 4 is set on the check valve and is passed through
Through-hole 8, the check valve are between the elastic force according to caused by the Fluid pressure and reset spring 4 for acting on check valve
Pressure difference and be correspondingly turned on or off, between the check valve and shell 1 by through hole 8 formed inner flow passage 10a, institute
The check valve stated forms external flow passage 10b, the inner flow passage 10a, external flow passage 10b energy by compression reseting spring 4
Pressure difference between enough elastic forces according to caused by the Fluid pressure and reset spring 4 for acting on check valve is adaptively closed
Or it opens.Specifically,
The check valve may include left check valve and right check valve, and the left check valve, right check valve are pacified respectively
In the hollow cavity of shell 1, reset spring 4 is set between left check valve and right check valve.Wherein, the left check valve
Including left plug 2 and left executive component 3, through hole 8 is opened up on the left executive component 3, as shown in Figure 5；The left side is stifled
First 2 are fixedly connected with shell 1, opposite sliding matching structure are formed between the left executive component 3 and shell 1, when left execution
When forming contact sealing structure between element 3 and left plug 2, the left working interface 11 and outlet 12 are disconnected.
When the action of hydraulic force of the fluid media (medium) in left working interface 11 in left executive component 3 and makes left 3 phase of executive component
It slides axially and compression reseting spring 4 to the right for shell 1, until the contact seal shape between left executive component 3 and left plug 2
State releases, and is sequentially communicated and is formed interior between the through hole 8, outlet 12 on the left working interface 11, left executive component 3
Portion runner 10a, as shown in Figure 1.
When left executive component 3 slides axially to the right relative to the continuation of shell 1, until between shell 1 and left executive component 3
When sealing state releases, at this point, the left check valve is in work fully open state, and right check valve is then in reset spring
It is in close state under 4 effects, therefore, the right working interface 13 and outlet 12 disconnect, and the inner flow passage 10a
It is in the open state, meanwhile, the left working interface 11 is directly connected to outlet 12 and forms external flow passage 10b, such as Fig. 2
It is shown.
Similarly, the right check valve includes right plug 6 and right executive component 5, is opened up on the right executive component 5
Through hole 8, as shown in Figure 5；The right plug 6 is fixedly connected with shell 1, shape between the right executive component 5 and shell 1
At opposite sliding matching structure, when forming contact sealing structure between right executive component 5 and right plug 6, the right work
Interface 13 and outlet 12 disconnect.
When the action of hydraulic force of the fluid media (medium) in right working interface 13 in right executive component 5 and makes right 5 phase of executive component
It slides axially and compression reseting spring 4 to the left for shell 1, until the contact seal shape between right executive component 5 and right plug 6
State releases, and is sequentially communicated and is formed interior between the through hole 8, outlet 12 on the right working interface 13, right executive component 5
Portion runner 10a, as shown in Figure 3.
When right executive component 5 slides axially relative to the continuation of shell 1, to the left until between shell 1 and right executive component 5
When sealing state releases, at this point, the right check valve is in work fully open state, and left check valve is then in reset spring
It is in close state under 4 effects, therefore, the left working interface 11 and outlet 12 disconnect, and the inner flow passage 10a
It is in the open state, meanwhile, the right working interface 13 is directly connected to outlet 12 and forms external flow passage 10b, such as Fig. 4
It is shown.
When reset spring 4 in the raw when, between left executive component 3 and shell 1, left executive component 3 and left plug 2
Between, between right executive component 5 and shell 1, between right executive component 5 and right plug 6 be respectively formed contact sealing structure, this
When, the left check valve, right check valve are in completely closed state, and therefore, the left working interface 11, right work connect
Mouth 13 is disconnected with outlet 12, and correspondingly, the inner flow passage 10a, external flow passage 10b are in closing shape
State.
In order to guarantee and improve the functional reliability and stability of left check valve, right check valve, the left executive component
3, right executive component 5 can use annular structural part, open up through hole 8 respectively in its bottom；Further, it can also be held on a left side
The intracavity bottom of units 3, right executive component 5 intracavity bottom be respectively formed installation step 9, as shown in figure 5, the installation
Step 9 matches connection with reset spring 4.
Further, the left plug 2, right plug 6 can be respectively fixedly connected with the opposite end in mandrel 7, described
Mandrel 7 extend through the through hole 8 on through hole 8 and right executive component 5 on left executive component 3, as Figure 1-Figure 4.
Wherein, between the mandrel 7 and left plug 2, between mandrel 7 and right plug 6, between left plug 2 and shell 1, right plug 6 with
Integrated molding structure is preferably used between shell 1, not only connection is reliable, but also can reduce parts machining process, with more preferable
The overall processing cost of ground reduction control valve.
It can be seen that being cooperated by left check valve and right check valve, and left check valve, right check valve can be with shells
Form inner flow passage 10a, external flow passage 10b between 1, inner flow passage 10a therein, external flow passage 10b can be according to acting on
Pressure difference between elastic force caused by the Fluid pressure and reset spring 4 of check valve adaptively closes or opens, thus
It is whole to enable the invention to carry out the modified tone of flow rank according to actual needs.When it is applied to variable valve timing regulating system, lead to
Cross inner flow passage 10a, external flow passage 10b is adaptively closed or opened, can achieve actual flow demand under adaptive operating condition
Purpose.In addition, compared with traditional control valve arrangement the spacer structure portion inside control valve can also be canceled, thus simple
The overall structure of control valve is changed, processing is more convenient, the inner space of control valve has been saved, moreover, also mitigating control valve
Weight, thus advantageously reduce control valve overall processing cost and improve control valve response speed.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
Made any modifications, equivalent replacements, and improvements etc. within the spirit and principles in the present invention should be included in guarantor of the invention
Within the scope of shield.
