[specific embodiment]

Referring to Fig. 1, what Fig. 1 was represented is structural representation of the present invention, a kind of automatic balance pipe, comprise body 5 and end cap 1, body 5 adopts nonferrous material, available iron material never, alleviating quality on the one hand, is that assurance iron core 4 can be avoided forming closed magnetic path between magnet and iron core 4 by magnetically-actuated on the other hand, body 5 adopts aluminum material in the present embodiment, have two apertures 51 on the body 5, after iron core 4 moved in the body 5, the hole 51 of an end was closed, 51 openings in the hole of the other end are in order to avoid form two airtight chambeies simultaneously.End cap 1 is a working of plastics, and there are three fins of symmetry at the end cap 1 endoporus place of keeping to the side, with annular groove wedging on the body 5 to realize connecting end cap 1 center drilling.

In described body 5, be provided with check valve, spring 3 and iron core 4, in the present embodiment, this check valve is soft colloidal materials, as shown in Figures 2 and 3, colloid check valve 2 lobed heads 21 also have cross mouth 22 at these plush copper 21 centers, this structure guarantees that the gas in the body 5 can outwards back down plush copper 21 and form exhaust outlet when pressurized, smoothly gas in the body 5 is discharged, when in the body 5 during iron core 4 counter motions, colloid externally gas pressure inwardly shrinks down, and the external diameter size of colloid check valve 2 is the same with hole size in the end cap 1, and cross is installed in the end cap 1, by the wedging of end cap 1 with body 5, colloid check valve 2 forms sealing with body 5 compactings.By the center drilling of end cap 1, expose and exhaust smoothly with the plush copper 21 of holding colloid check valve 2.

As shown in Figure 4; iron core 4 is a ferrous material; it is the object of magnetically-actuated; body 5 mass-unbalance and automatically reply the control object of balance; for guaranteeing its freely-movable in body 5 and the air-tightness in the motion process; has very little matched in clearance between iron core 4 and the body 5; this also is one of key parameter with the slow return characteristic of snap-action of the present invention; iron core 4 is contained in the body 5, and is matched in clearance between the body 5, can move freely; iron core 4 two ends have the little shaft shoulder 41; on the one hand be near end face so that magnetically-actuated is more reliable, protect spring 3 to be compacted avoiding on the other hand, prolong the service life of spring 3.

Two springs 3 at iron core 4 two ends are identical, freely be contained in the

body
