Flowed to second chamber, while damping hole in the open state is fewer and fewer so that fluid enter the difficulty of second chamber by
Cumulative big, the fluid in first chamber enters second chamber and needs bigger power, so that the damping force for generating damper is bigger.
When plunger does extensional motion, the fluid of second chamber is flowed into liquid capsule, while damping hole in the open state is increasingly
More, so that fluid is gradually reduced by the difficulty that damping hole enters in liquid capsule, the fluid of second chamber is quickly reduced, so that the
Negative pressure in two chambers increases, and causes the fluid in second chamber to enter the damping force that liquid capsule is subject to and becomes larger.Therefore, of the invention

Make throttling element that plunger not followed to generate larger movement with the stretching of plunger, i.e., throttling element is in the range of position-limiting unit setting
It is mobile, avoid the problem that shock absorber fluids damping force reduces caused by throttling element is mobile in sleeve with the movement of plunger, protects
Demonstrate,prove the damping effect of damper.On the other hand, the setting of position-limiting unit can also realize that damper mentions under different shock conditions
For different damping forces.Specifically, throttling element can be by moving in the range of setting when washing machine generates smaller tremors
Mode increase while moving (ram compression) or reduce the quantity of the opening of (when plunger extensional motion) damping hole, and then reduce
The resistance that fluid back and forth flows in liquid capsule and second chamber, so that the damping force that damper provides in smaller tremors also reduces,
The phenomenon that vibration of reduction cylindric washer is transmitted to washing machine shell by damper in turn, guarantees running smoothly for washing machine, makes an uproar
Sound is small.It is big due to shaking when washing machine generates big shake, shake speed fastly, throttling element does not move substantially relative to sleeve at this time, phase

To two rows damping hole 133 is provided with, the angle between the axis of damping hole 133 and the axis of pipe structure 132 is 90 °,
It is exactly damping hole 133 perpendicular to horizontally arranged (according to orientation shown in Fig. 3).Pedestal 131 is in circumferential outer rim and the first chamber
The inner wall of room 112 matches, and if first chamber 112 is cylindrical cavity, pedestal 131 is cylindrical structure, and cylindrical type knot
The cross-sectional diameter of structure cross-sectional diameter and cylindrical cavity is roughly equal.
From the description above it can be seen that on the one hand, since the open end of liquid capsule 14 is fixedly connected with plunger 12, liquid capsule 14
Closed end be connected with sleeve 11, therefore, plunger 12 move back and forth during, plunger 12 can stretch or compress liquid capsule

One end that liquid capsule 14 and liquid capsule 14 are provided in 112 is sealingly connected to plunger 12, therefore, in plunger 12 relative to sleeve 11
During being slided, 4 meetings of hydraulic oil are flowed between liquid capsule 14 and second chamber 122, are avoided since hydraulic oil 4 is let out
The problem of damper 1 fails caused by dew.And what pedestal 131 matched in the inner wall of circumferential outer rim and first chamber 112
Set-up mode also enables pedestal 131 to limit the horizontal position of pipe structure 132 so that plunger 12 and throttling element 13 it
Between sliding more smoothly and stablize, avoid since throttling element 13 is during the work time due to there is the pipe structure of throttling element 13
The case where damper 1 fails caused by 132 appearance biasing phenomenons.
In other words, compared to the existing damper of rotating drum washing machine for carrying out damping using frictional force, of the invention subtracts
The damping force of the generation of device 1 damping force inconstant at any time is shaken, is changed with the amplitude of vibration, the vibration of vibration
Width is bigger, and the damping force for resisting the vibration that damper 1 generates is also bigger.And damper 1 of the invention can't be because of
Phenomena such as abrasion and the problem of cause damper 1 to fail after a period of operation, to efficiently solve existing skill
Damping force is unable to the problem of consecutive variations in art, substantially enhances the damping effect of damper 1, improves user and is washed using roller
The user experience of clothing machine.
Herein it should also be noted that, in the present embodiment with no restriction to the quantity and diameter of damping hole 133, for difference
For the damper 1 of model, the quantity and diameter of damping hole 133 are not quite similar.For example, for smaller damper
For 1, the diameter of damping hole 133 can be in the thickness section of a few tenths of a mm to several millimeters；And the damper 1 of relatively large-scale
It says, the diameter of damping hole 133 can be in several millimeters to more than ten millimeters of thickness section.
Those skilled in the art will also be appreciated that the preferred arrangement of above-mentioned throttling element 13 is used merely to explain this
The principle of invention, it is not intended that with limit the scope of the invention, under the premise of without departing from the principle of the invention, this field skill
Art personnel can also carry out any form of adjustment to above-mentioned set-up mode, to adapt to more specifical application.For example,
The section of damping hole 133 can also be ellipse or rectangle；Pedestal 131 can be fixed with pipe structure 132 by the way of being spirally connected
Connection；Angle between the axis of damping hole 133 and the axis of pipe structure 132 can be any angle, such as the axis of damping hole 133
The angle of line and the axis of pipe structure 132 in horizontal direction to the left is 45 °.
Referring next to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, wherein Fig. 4 is the damper for roller washing machine of the invention
The structural schematic diagram of position-limiting unit；Fig. 5 is partial enlargement diagram of the Fig. 3 at A.
As shown in figure 3, being additionally provided with position-limiting unit 15 on sleeve 11 in a kind of more preferably embodiment, limit
Unit 15 is be arranged throttling element 13 in a manner of movement in the range of setting relative to sleeve 11.Referring to Fig. 4 and Fig. 5, specifically
For, position-limiting unit 15 includes cylindrical body 151, claw 152, the second fixation hole 153 and slot structure 154, corresponding sleeve
The through-hole 113 (referring to Fig. 2) to match with claw 152 is provided on 11, and fixed with the first of the second fixation hole 153 cooperation
Hole 114 (referring to Fig. 5).Preferably, claw 152 and the second fixation hole 153 are four, and circumferentially equal along the inner edge of cylindrical body
Cloth, corresponding through-hole 113 and the first fixation hole 114 are also four.Position-limiting unit 15 passes through on the second fixation hole 153 and sleeve 11
The first fixation hole 114 be fixedly attached, such as be spirally connected by screw or pin shaft.Claw 152 then passes through matched through-hole 113
It protrudes into the first chamber 112 of sleeve 11, and claw 152 is greater than the thickness of pedestal 131 at a distance from 112 left end of first chamber
(referring to Fig. 5).It, being capable of left end in first chamber 112 and claw in this way, throttling element 13 is by the limit of position-limiting unit 15
It is moved in the range of being set out between 152 (i.e. in the range of length shown in Fig. 5 is x).Slot structure 154 can then limit
15 sets of unit be connected to sleeve 11 during make cylindrical body 151 generate elastic deformation (i.e. the inner edge of cylindrical body 151 is supportted
Open), and then while making 15 sets of position-limiting unit to be connected to sleeve 11, is easier.
The advantages of above-mentioned set-up mode is: on the one hand, position-limiting unit 15 is so that throttling element 13 is being set relative to sleeve 11
The set-up mode moved in fixed range makes throttling element 13 that plunger not followed to generate larger movement with the stretching of plunger 12, i.e.,
Throttling element 13 only moves in the range of position-limiting unit 15 is set, and throttling element 13 is avoided to move in sleeve 11 with the movement of plunger 12
The problem of 1 fluid damping forces of damper reduce caused by dynamic, guarantees the damping effect of damper.On the other hand, position-limiting unit
15 setting can also realize that damper 1 provides different damping forces under different shock conditions.Specifically, being produced in washing machine
When raw smaller tremors (such as roller 3 is when high-speed smooth is run), position-limiting unit 15 can pass through mobile side in the range of setting
Formula increases (when 12 compression movement of plunger) or reduces the quantity of the opening of (when 12 extensional motion of plunger) damping hole 133, and then subtracts
The resistance that small fluid back and forth flows in liquid capsule 14 and second chamber 122, so that the damping that damper 1 provides in smaller tremors
Power also reduces, and the vibration for reducing roller 3 is transmitted on washing machine shell by damper 1, guarantee washing machine run smoothly, noise
It is small.It is big due to shaking when washing machine generates big shake (when such as roller 3 is from stationary state setting in motion), shake speed fastly, this time limit
Bit location 15 does not move substantially relative to sleeve 11, is equivalent to without relative motion between position-limiting unit 15 and sleeve 11, fluid exists
Biggish resistance is generated when back and forth flowing in liquid capsule 14 and second chamber 122, so that damper 1 is capable of providing big damping force with fast
Speed reduces the vibration that washing machine generates.
It will be appreciated to those of skill in the art that the set-up mode of above-mentioned position-limiting unit 15 is not unique, without departing from
It is any that the set-up mode between throttling element 13 and sleeve 11 without relative motion can be made to fall into this hair in the case of the principle of the invention
Within bright protection scope.For example, referring to Fig. 6, Fig. 6 is the limit list of the damper for roller washing machine of the invention
The partial enlargement diagram of second of embodiment of member.As shown in fig. 6, being preferably carried out in mode in another kind, limit is single
Member 15 can also be the ramp projections structure being arranged in sleeve 11, and the pedestal 131 of throttling element 13 is to be pressed into bulge-structure
Mode is limited in the setting range between the bulge-structure and the left end of first chamber 112 that (length i.e. shown in Fig. 6 is
In the range of x), to realize ramp projections structure to the limit function of throttling element 13.
With further reference to Fig. 3, in a kind of more preferably embodiment, damper 1 further includes at least one elastic component,
At least one elastic component is arranged in a manner of preventing plunger 12 from sliding.Preferably, an elastic component has can be set in damper 1
16, and elastic component 16 can be set to all have compressive deformation when plunger 12 does compression movement, do stretching fortune in plunger 12
There is tensile deformation when dynamic.Orientation as shown in Figure 3, the both ends of elastic component 16 respectively with the right end annular surface of pipe structure 132 and
The right side of two chambers 122 is connected.Specifically, elastic component can be spring, leaf spring or elastomer block.
Have the advantage that in this way: the elastic force that elastic component 16 is generated when plunger 12 moves reciprocatingly can be further
The vibration that washing machine generates is offset, further enhances the damping effect of damper 1, this effect is when plunger 12 does compression movement
It is particularly evident.
Certainly, the quantity of elastic component and set-up mode and not exclusive, those skilled in the art can also make it accordingly
Adjustment, so that it adapts to more specifical application scenarios.If elastic component can also only be arranged two, one is set to the second chamber
In room (such as elastic component 16), another is then set in liquid capsule 14, both ends respectively with the right circular face of pedestal 131 and plunger 12
Second end be connected, such set-up mode can equally complete elastic force offset vibration effect.
Referring to shown in Fig. 7 and Fig. 8, Fig. 7 is partial enlargement diagram of the Fig. 3 at B；Fig. 8 is of the invention is used for
The partial enlargement diagram of second of embodiment of the sealing element of the damper of roller washing machine.
