Power is concentrated.Blade 30 stretches into the discharge chambe 21, and the lower end of blade 30 is pressed on recess side 12.Bottom 11 has symmetrical cloth
The venthole 14 of the three groups of φ=4mm set, recess side 12 have the air admission hole 15 for three groups of φ=9mm being arranged symmetrically.Adjacent
Recess side 12 intersects at a near point 71, and the excircle of the rotor 20 of φ=62.5mm connects near point.The recess side 12 is by gradually
Burst at the seams 72 and the composition of circular arc line 73 positioned at the involute both sides, and arc-shaped the 73 of the adjacent recess side 12 is tangential on closely
Point 71.
With reference to Fig. 2 to 4, when rotor 20 rotates, blade 30 is pressed in the madial wall of recess side 12 under the influence of centrifugal force.
20mm blades 30 break away from the air admission hole 15 of discharge chambe 21 into then breakking away out from the venthole 14 of discharge chambe 21.Blade 30 is in cunning
Continuous compressed gas volume during dynamic, high pressure gas is discharged from venthole 14.Enter from air admission hole 15 with stylish gas,
Full of discharge chambe 21, prepare for the subsequent work period.Preferably, sliding slot 22 tilts backwards, is conducive to blade 30 and throws away.Blade
The structure of 30 lower ends is flat face 31 and the arcwall face positioned at R=1.5mm of 31 both sides of flat face, 3mm（32、33）.Arcwall face
33 contact recess sides 12.Recess side 12 is smooth inner arc structure, and the lower end of blade 30 is pressed in inner arc structure, machine
