It reuses sealing material to be sealed, can also attain the results expected；Fuel Tanking Unit 6 and outer housing can also will be balanced by mold
1 integrally casting shaping, the utility model are not construed as limiting this.
Specifically, the balance Fuel Tanking Unit 6 includes shell 62, and the shell 62 forms the oil storage space；The bullet
Property component 61 include elastic device 611 and sealing element 612；
The inside of the sealing element 612 and the shell 62 slidably contacts with, and is configured to the oil storage space
Be separated into oil storage space 613 and lower oil storage space 614, and by the oil body stored in the upper oil storage space 613 and it is described under
Oil storage space 614 is isolated；
The elastic device 611 supports the sealing element 612, and is arranged in the lower oil storage space 614.
It should be noted that the oil liquid in the oil storage room 5 is merely stored in due to the setting of the sealing element 612
In the upper oil storage space 613, without entering in the lower oil storage space 614.
Since the elastic device 611 supports the sealing element 612, it can provide to the sealing element 612 and squeeze upwards
The power of pressure, and then oil liquid of the sealing element 612 into the upper oil storage space 613 is made to apply pressure.
Specifically, the pressure that oil liquid of the sealing element 612 into the upper oil storage space 613 applies is F=PS,
In, P is the pressure of oil liquid, and S is the area that the sealing element 612 is contacted with oil liquid.
When the original state of elastic device 611 is arranged, the pressure P of oil liquid can be applied to according to damper0, the sealing
The area S and the sealing element 612 that part 612 is contacted with oil liquid calculate spring with the frictional force f on the inside of the shell 62
It is applied to the power F of the sealing element 6121=P0S+f (perfect condition).
Preferably, in one embodiment of the utility model, the shell 62 is cylindrical body or cube, and the shell
The material of body 62 can be identical or different with the material of the outer housing 1.In various embodiments, the shell 62 uses
Unused material, such as alloy, steel, composite material etc..
Further, the shell 62 is integrally formed, to further increase intensity.
Preferably, in one embodiment of the utility model, the sealing element 612 is parallel to the bottom surface of the shell 62
One end of setting, the elastic device 611 supports the sealing element 612, and the other end is fixed on the inner bottom surface of the shell 62.
Wherein, since the sealing element 612 adapts to the oil storage space that the shell 62 is formed, it is preferably
Round or rectangle.
Preferably, the sealing element 612 is made of elastic material, such as elastic seal ring.

612 provide upward power.
Preferably, the elastic device 611 is parallel to the side of the shell 62, and one end supports the sealing element
612, the other end is fixed on the center of 62 inner bottom surface of shell.
The elastic device 611 can be spring, elastic pump etc..In one embodiment of the utility model, the bullet
Property device 611 be spring.
It should be noted that when the damper internal pressure increases, i.e., when the pressure P of oil liquid increases, the sealing element 612
The pressure F that oil liquid into the upper oil storage space 613 applies also is increased with it, therefore the elastic device 611 is compressed,
So that the sealing element 612 moves down, the volume of the upper oil storage space 613 increases, and the lower oil storage space 614
Volume reduces.
When the damper internal pressure reduces, i.e., when the pressure P of oil liquid reduces, the sealing element 612 is to the upper oil storage
The pressure F that oil liquid in space 613 applies also reduces therewith, therefore the elastic device 611 stretches, so that the sealing
Part 612 moves up, and the volume of the upper oil storage space 613 reduces, and the volume of the lower oil storage space 614 increases.
Damper provided by the utility model, due to being provided with balance Fuel Tanking Unit 6, so that the oil liquid in damper can flow
Enter into the balance Fuel Tanking Unit 6, and is additionally provided with elastic parts 61 in the balance Fuel Tanking Unit 6, it can be to balance Fuel Tanking Unit 6
The oil liquid of interior storage applies the pressure with damper internal pressure balance, it is achieved that the elastic variable of damper oil storage space, into
And it avoids the performance of damper oil mass is how many is influenced by injection.
Compared with the existing technology, damper provided by the embodiment of the utility model can be obviously improved stability and performance, and
Structure is simple, is with a wide range of applications.
