It has been respectively communicated with upper air portion 2 and upper exhaust portion 19 on upper 18 outer wall of pneumatics chamber, has distinguished on lower 15 outer wall of pneumatics chamber
It is communicated with lower intake section 3 and lower exhaust portion 16.It is respectively arranged with breather check valve, upper exhaust portion on upper air portion and lower intake section
It is respectively arranged with exhaust check valve in lower exhaust portion.
The second through-hole 13 is provided on 12 outer wall of the venting cavity so that the air pressure in the venting cavity 12 and outside atmosphere
It presses identical, when being conducive to the oil pressure opposite outer atmospheric pressure in upper oil cavitie 5 and increasing or reducing, realizes the opposite of floating piston 4
Movement.
The diameter of first cavity is less than the diameter of the second cavity, and the diameter of pneumatics piston 17 is less than the diameter of floating piston 4,
Be conducive to improve air compression ratio.The area of the area Relative Floating piston 4 of pneumatics piston 17 is smaller, the compressed flow velocity of air
Bigger, air compression ratio is higher.
For with certain thickness sleeve lateral wall, the upper air portion 2 and upper exhaust portion 19 are divided on the outside of first cavity periphery
The upper air venthole 2 and upper exhaust venthole 19 that Wei not be connected to upper pneumatics chamber 18 through sleeve lateral wall, the lower intake section 3
It is respectively the lower air inlet venthole 3 being connected to lower pneumatics chamber 15 through sleeve lateral wall and lower exhaust venthole with lower exhaust portion 16
16。
The upper air venthole 2 and upper exhaust venthole 19 are respectively located at the upper end of the upper pneumatics chamber 18, institute
It states lower air inlet venthole 3 and lower exhaust venthole 16 is located at the lower end of the lower pneumatics chamber 15.To make the pneumatics
When piston 17 moves up and down, air inlet and exhaust work(can be smoothly realized in the upper pneumatics chamber 18 and the lower pneumatics chamber 15
Energy.
The upper air venthole 2 and lower air inlet venthole 3 are connected by check valve with extraneous air respectively；On described
It is vented venthole 19 and lower exhaust venthole 16 is prominent to outside sleeve lateral wall respectively, and pass through check valve and external air accumulator respectively
It is connected.
The venting cavity 12 is connected by the second through-hole 13 with extraneous air.
The first through hole 20 is uniform, arranged symmetrically in flow check piston 6, is conducive to make each in upper oil cavitie 5 and lower oil cavitie 7
Partial oil pressure is uniform.
First cavity and the second cavity are not connected to mutually, and upper pneumatics chamber 18 is not connected to mutually with lower pneumatics chamber 15, venting cavity
12 are not connected to mutually with upper oil cavitie 5, are advantageously implemented the vibration damping and air compression function of the present embodiment damper.
For with plate 21 in certain thickness sleeve, the power rail 14 between at the top of first cavity bottom and the second cavity
Plate 21 in sleeve are provided with the first gasket in power rail 14 and sleeve between plate 21.First gasket can ensure
In mutual disconnected state between one cavity and the second cavity.
It is provided with the second gasket between the part that piston rod 8 extends to 7 lower part of lower oil cavitie and sleeve 10.Second gasket
It can ensure between lower oil cavitie 7 and extraneous air in mutual disconnected state.
10 top of the sleeve is provided with location and installation portion 1, and 8 lower end of the piston rod is provided with lower location and installation portion
9.The present embodiment damper is connected on external device (ED) by upper location and installation portion 1 and lower location and installation portion 9.
When work, when sleeve 10 is vibrated to be moved downward, originally 4 relative sleeve 10 of floating piston is static, and throttling is lived
Plug 6 and 8 relative sleeve 10 of piston rod tool are there are one upward stroke, and 5 space of upper oil cavitie reduces, and 7 space of lower oil cavitie increases, due to
The presence of piston rod 8, the piston rod portion positioned at the bottom part down of lower oil cavitie 7 enter in lower oil cavitie 7, therefore, the sky of upper oil cavitie 5
Between reduction amount be equal to the space increase of lower oil cavitie 7 plus the new volume into the piston rod portion in lower oil cavitie 7, therefore, on
The space reduction amount of oil pocket 5 is more than the space increase of oil pocket 7, causes the oil pressure in upper oil cavitie 5 to increase, the oil in upper oil cavitie 5
Liquid pushes 4 relative sleeve 10 of floating piston to move upwards, and pushes 17 relative sleeve 10 of pneumatics piston upwards by power rail 14
Movement, and then the air of upper pneumatics chamber 18 is compressed, and the air of compression is discharged into external air accumulator by upper exhaust venthole 19
In, at the same time, lower pneumatics chamber 15 passes through lower 3 air inlet of air inlet venthole.
When sleeve 10 is vibrated to be moved upwards, originally 4 relative sleeve 10 of floating piston is static, flow check piston 6 and work
There are one downward stroke, 5 spaces of upper oil cavitie to increase for 8 relative sleeve 10 of stopper rod tool, and 7 space of lower oil cavitie reduces, due to piston rod 8
Presence, the part of piston rod being located at originally in lower oil cavitie 7 is moved to outside lower oil cavitie 7, and therefore, the space of upper oil cavitie 5 increases
Therefore the volume that a large amount of space reduction amounts equal to lower oil cavitie 7 add a part of piston rod being moved to outside lower oil cavitie 7 oils
The space increase of chamber 5 is more than the space reduction amount of oil pocket 7, and the fluid in lower oil cavitie 7 can not fill up upper oil cavitie 5 in time,
The oil pressure in upper oil cavitie 5 is caused to reduce, 4 relative sleeve 10 of floating piston moves downward under the action of negative pressure, and passes through power
Bar 14 drives 17 relative sleeve 10 of pneumatics piston to move downward, and compresses the air of lower pneumatics chamber 15, and the air of compression is passed through
Lower exhaust venthole 16 is discharged into external air accumulator, and at the same time, upper pneumatics chamber 18 passes through 2 air inlet of upper air venthole.
Therefore, suction and discharge process twice is completed within a vibration period of the present embodiment damper, when vibration continues
It can continuously be inflated to external air accumulator, realize that vibrational energy and air compress transformation of energy.
The present invention, will not while damper is Vehicle damper by adding air-breathing and compressing device in damper
The vibrational energy of profit is stored by being converted into the compression energy of air, realizes the recycling of automobile vibrational energy.Compressed air one
Aspect can provide air source for the air spring of vehicle suspension, can replace traditional electric compressor, reduce electricity consumption, save energy
Source is reduced since air compressor machine starts the damage to automobile circuit repeatedly；On the other hand compressed air can be imported vehicle startup
The admission line of machine realizes engine booster, improves combustion rate.
It should be noted last that：Technical scheme of the present invention that the above embodiments are only illustrative and not limiting is any right
The equivalent replacement and do not depart from the modification of spirit and scope of the invention or local replacement that the present invention carries out, should all cover in this hair
Within bright protective scope of the claims.
