Elastic diaphragm 32 on end on.The area A of diaphragm 32MCross-sectional area A more than switching piston 31Z.Arranged by this
Execute, in the case of above-mentioned two passage 23,24 is loaded by negative pressure, make switching piston 31 move downward, and, passage 23,24
Between interface channel 33 open.
A kind of method of suction air on control and suck opening 17 comprises the steps of.First, to suction channel
23 load suction air pressure (such as ,-p1 approximates-200mbar).
Once suction opening 17 is covered by page 6, then produce negative pressure in passage 23, and described negative pressure holds page 6.This
Time, load suction air pressure (such as ,-p2 approximates-200mbar) to the second suction channel 24.Face with switching piston 31
Long-pending ASCompare, by the area A that diaphragm 32 is biggerMSwitching piston 31 is made to pull down and make interface channel 33 to open.
Therefore, being provided with negative pressure (such as ,-p approximates-200mbar) in whole switching mechanism 22, described negative pressure can be by
Page 6 is fixed.
In the next step, the suction air of first passage 23 is turned off and (that is, loading suction air to second channel 24
