Slot is set to one end that coil holder plugs tuyere, and the both ends of the discouraged micro-groove are inside and outside coil holder end face, described to let out
Airtight mounting pressure is set on the micro-groove that loses heart and forms the discouraged micro-hole.
So set, the discouraged micro-hole of the diameter very little needed for us can be formed simply very much.
Further preferably are as follows: the cross section of the discouraged micro-groove is triangular in shape.
It is arranged such, it is therefore intended that micro-groove cross section of losing heart is very small, and the setting of triangle is convenient for discouraged micro-groove to exist
Opening up on coil holder.
Further preferably are as follows: the discouraged micro-groove is linear, arc, waveform.
So set, discouraged micro-groove is made integrally to be in bar shaped, that is, the discouraged micro-hole formed is longer, so that air leakage amount
It floats smaller, is vented more linear.
Further preferably are as follows: one end that the coil holder plugs tuyere is provided with for keeping gas vent and discouraged micro-hole pair
There is limited step in position.
So set, axial limiting tuyere, so that the axle center of gas vent and inlet channel A are in same level, no
It can occur to cause to misplace because tuyere slides.
Further preferably are as follows: the gas vent periphery is provided with annular grooving.
So set, annular grooving is located at, it may not need and accomplish gas vent and inlet channel A without at accurate guarantee
In that can be connected on same axial line, assembling is easily facilitated.
Further preferably are as follows: be provided on the inner wall of the coil holder several for the radial fin for limiting iron core.
So set, keep stability of iron core when sliding axially, guarantee will not to occur when being powered double swerve and shadow
Ring leakproofness.
