Chamber 12a be seal chamber, the second air cavity 12b be communicated with the atmosphere by air guide channel 111a for come the pushing and rebound to compression bar 2
Process is described.
First refering to fig. 25,26, compression bar 2, which is in, pushes initial position.Gas in first air cavity 12a and the second air cavity 12b
Body pressure can be equal, can all be atmospheric pressure.Second cavity 1b memory is placed with content 800 or air, piston 15 with
Confined planes 202 are detached from, and are offseted with pedestal portion 172, and through-hole 15a is in close state.The conical body 160 of valve body 16 with open
Mouth 112a cone match, so that opening 112a is in close state.Since compression bar 2 by external force to push pushing initial position.
Referring again to Figure 27,28, compression bar 2, which is in, pushes middle position.With the pushing of compression bar 2, gas in the first air cavity 12a
Pressure start to reduce, in the second air cavity 12b the pressure of gas be equal to atmospheric pressure, the first air cavity 12a and the second air cavity 12b production
Raw gas pressure difference.In this course, the frictional force due to piston 15 by 112 inner wall of second shell portion is influenced, piston
15 on pillar 201 along the sliding in the direction far from pedestal portion 172, and separated with pedestal portion 172, so that through-hole 15a is opened.
The conical body 160 and opening 112a cone match of valve body 16, so that opening 112a is in close state.
When piston 15 along far from pedestal portion 172 direction slide into offset with confined planes 202 after, piston 15 start by bar
The driving of ontology 20 is to moving downward, to squeeze content 800 or air in the second cavity 1b.It is beaten since through-hole 15a is in
Open state, and the 112a that is open is in close state, the content 800 or air in the second cavity 1b can successively pass through through-hole
15a, drainage channel 171a, passing away 20a and assignment channel 93a and the second cavity 1b is discharged.Content in second cavity 1b
The discharge path of object 800 or air is as shown in the dotted arrow L in Figure 28.
Referring again to Figure 29,30, compression bar 2, which is in, pushes end position.At this point, content 800 in the second cavity 1b or
The second cavity 1b has been discharged in air to the maximum extent.The pressure of gas is reduced to minimum value, the first air cavity in first air cavity 12a
Gas pressure difference between 12a and the second air cavity 12b reaches maximum value.Through-hole 15a is still within opening state, and the 112a that is open
It is still within closed state.After the external force revocation that compression bar 2 is subject to, piston portion 21 can be in the gas pressure in the first air cavity 12a
It is sprung back under the action of the resultant force of the gas pressure in the second air cavity 12b, compression bar 2 is driven to spring back since pushing end position.
Figure 31,32,33 are turned finally to, compression bar 2 is in position in rebound.With the rebound of compression bar 2, in the first air cavity 12a
The pressure of gas starts to increase, and the pressure of gas is equal to atmospheric pressure, the first air cavity 12a and the second air cavity in the second air cavity 12b
12b still has gas pressure difference.In this course, the frictional force due to piston 15 by second shell portion 112 inner wall
Influence, piston 15 on pillar 201 along close to pedestal portion 172 direction sliding, separated with confined planes 202 and with pedestal portion
172 offset, so that through-hole 15a is closed.The conical body 160 of valve body 16 is separated with opening 112a, so that opening 112a is in
Opening state.
When piston 15 along close to pedestal portion 172 direction slide into offset with pedestal portion 172 after, piston 15 is by pedestal portion
172 drivings are to moving upwards, to increase the volume of the second cavity 1b.Since through-hole 15a is in close state, and it is open at 112a
Content 800 or air in opening state, vessel 91 can be inhaled into the second cavity 1b via opening 112a.
Content 800 or air in vessel 91 enter the path such as the void in Figure 33 of the second cavity 1b via opening 112a
Shown in line arrow M.
Compression bar 2 can recoil to Figure 25, push initial position shown in 26, so that compression bar 2 is suitable for being again depressed.It is pressing
With springback process, content 800 or air in vessel 91 are discharged vessel 91 for the multiple pressing of bar 2.
In another embodiment of the utility model, as shown in Figure 35 to Figure 43, for improve pump assembly 90 leakproofness,
The structure of sealing ring 13, inner housing 12 and gland 14 is changed.
Specifically, sealing ring 13 includes the annular seating 130 for surrounding the setting of bar body 20, annular epipharynx 131 and annular outer lip
132；Bar body 20 radially, annular seating 130 be arranged between bar body 20 and ring wall 123；In the axial direction of bar body 20
On, annular seating 130 offsets with roof 121；One end of annular epipharynx 131 and annular outer lip 132 is connect with annular seating 130 respectively,
The other end offsets with bar body 20 and ring wall 123 respectively.
As shown in Figure 37,42,43, it is recessed for V-arrangement that annular epipharynx 131 and annular outer lip 132 limit annular, cross section
The notch of slot, the groove is arranged towards gland 14.
After the other end of annular epipharynx 131 and annular outer lip 132 offsets with bar body 20 and ring wall 123 respectively, the first gas
Contacting for chamber 12a and ambient atmosphere is cut-off, the air pressure of the first air cavity 12a be equal to the inner circumferential space of annular epipharynx 131 with
And the air pressure in the external circumferential space of annular outer lip 132；Annular epipharynx 131 and annular outer lip 132 limit annular, cross section
It is equal to the air pressure of ambient atmosphere for the air pressure in the groove of V-arrangement.
During compression bar 20 moves to the pushing end position in Figure 36 from the pushing initial position in Figure 35, first
Air cavity 12a is gradually stretched, and internal air pressure is gradually reduced, and leads to inner circumferential space and the annular of annular epipharynx 131
The air pressure in the external circumferential space of outer lip 132 is gradually reduced, and then leads to inner circumferential space and the annular of annular epipharynx 131
The external circumferential space of outer lip 132 and annular epipharynx 131 and groove that annular outer lip 132 limits annular, that cross section is V-arrangement
Between pressure difference be gradually increased, be pressed on bar body 20 and ring wall respectively so as to cause annular epipharynx 131 and annular outer lip 132
123, and pressure increases with the gradually stretching of the first air cavity 12a, realizes dynamic sealing.
The process of above-mentioned dynamic sealing helps to reduce the resistance that bar body 20 moves, and can be improved pump assembly 90
Leakproofness.
