When external device (ED) is vibrated, double diaphragm air compression dampers vibrate, and sleeve 1 is caused up and down reciprocatingly to be transported It is dynamic, make the first upper oil cavitie 12 and the 13 two-part volume variation of the first lower oil cavitie and oil pressure is made to change, causes upper diaphragm compressor reducer 2 With the deformation of elastic membrane in lower diaphragm compressor reducer 3, to complete suction and discharge process.Specifically, passing through lower air chamber 23, upper air The conversion of vibrational energy and air compression energy is realized in air inlet, the bleeding of chamber 32.
Specifically, when sleeve 1 is vibrated move upwards when, 12 space of the first upper oil cavitie increases, and negative pressure is formed, on second Oil in oil pocket 22 is back to the first upper oil cavitie 12, while the first bullet by the first adjustable throttling piece 24 and sleeve upper arm chamber 14 Power film 21 deforms upwards under the action of negative pressure, and lower air chamber 23 completes breathing process by the first breather check valve 25;Together When, 13 space of the first lower oil cavitie reduces, and pressure increases, can by sleeve underarm chamber 15 and second by 13 inner fluid of the first lower oil cavitie Flow regulating valve piece 34 is pressed into the second lower oil cavitie 33, while the second elastic membrane 31 is upwardly-deformed under oil pressure effect, makes air chamber 32 complete exhaust process by second exhaust check valve 36, and are inflated to external air accumulator, i.e., upper diaphragm compresses in the process 2 air-breathing of device, lower diaphragm compressor reducer 3 are inflated to air accumulator.
When sleeve 1 is vibrated to be moved downward, the direction of motion and the above process of fluid are on the contrary, lower diaphragm compressor reducer 3 Air-breathing, upper diaphragm compressor reducer 2 are inflated to air accumulator.Specifically, when sleeve 1 is vibrated move downward when, the first lower oil cavitie 13 Space increases, and forms negative pressure, and the oil in the second lower oil cavitie 33 is flowed back by the second adjustable throttling piece 34 and sleeve underarm chamber 15 To the first lower oil cavitie 13, while the second elastic membrane 31 deforms downwards under oil pressure effect, makes air chamber 32 by second Breather check valve 35 completes breathing process;Meanwhile 12 space of the first upper oil cavitie reduces, pressure increases, will be in the first upper oil cavitie 12 Fluid is pressed into the second upper oil cavitie 22 by sleeve upper arm chamber 14 and the first adjustable throttling piece 24, while the first elastic membrane 21 is in oil The lower deformation downwards of pressure effect makes lower air chamber 23 complete exhaust process by first exhaust check valve 26, and to external air accumulator Inflation.
It is as stronger in worked as the excitation vibrated moved upwards of sleeve 1 when external drive is stronger, lead to the second lower oil cavitie 33 When oil pressure is excessive, the second gate gurgle valve 38 is opened, and the fluid in the second lower oil cavitie 33 enters the second draining chamber by second pipe 37 303, complete buffering;When said external, which encourages, to disappear, under the effect of the second elevated pressure nitrogen air cavity 304, the 4th elastic membrane 302 is to the Two draining chambers, 303 direction movement auxiliary oil return, even if the fluid in the second draining chamber 303 is back to the second lower oil cavitie 33, second Gate gurgle valve 38 is closed.
Second adjustable throttling piece 34 is located at the lower section of second pipe 37, makes when 33 oil pressure of the second lower oil cavitie is excessive, suitable Profit completes buffering course.
It is as stronger in worked as the excitation vibrated moved downward of sleeve 1 when external drive is stronger, lead to the second upper oil cavitie 22 When oil pressure is excessive, the first gate gurgle valve 28 is opened, and the fluid in the second upper oil cavitie 22 enters the first draining chamber by first pipe 27 203, complete buffering;When said external, which encourages, to disappear, under the effect of the first elevated pressure nitrogen air cavity 204, third elastic membrane 202 is to the One draining chamber, 203 direction movement auxiliary oil return, even if the fluid in the first draining chamber 203 is back to the second upper oil cavitie 22, first Gate gurgle valve 28 is closed.
First adjustable throttling piece 24 is located at the top of first pipe 27, makes when 22 oil pressure of the second upper oil cavitie is excessive, suitable Profit completes buffering course.
Can by adjust the first adjustable throttling piece 24 adjust fluid into and out of the second upper oil cavitie 22 speed;Pass through adjusting Second adjustable throttling piece 34 adjusts fluid into and out of the speed of the second lower oil cavitie 33, and then it is empty to adjust the double diaphragms of the utility model The damping capacity of air pressure contracting damper.
The utility model in damper by adding air-breathing and compressing device, while damper is Vehicle damper, Unfavorable vibrational energy is stored by being converted into the compression energy of air, realizes the recycling of automobile vibrational energy.Compression is empty On the one hand gas can provide air source for the air spring of vehicle suspension, can replace traditional electric compressor, reduce electricity consumption, save The energy is reduced since air compressor machine starts the damage to automobile circuit repeatedly;On the other hand compressed air can be imported to vehicle hair The admission line of motivation realizes engine booster, improves combustion rate.
It should be noted last that:The technical solution of the utility model that the above embodiments are only illustrative and not limiting is appointed What to the utility model carry out equivalent replacement and do not depart from the spirit and scope of the utility model modification or part replace, It should cover within the scope of the utility model claims are protected.
