It crosses the front-axle hole 29 and a rear spindle 38 is extended back by the swivel 30 and stretches into the rear axis hole 69, which is
It sticks in the protecgulum 50 and the rear cover 60.In other embodiment, the visual demand of quantity of the groove 32 changes, the blade 34
Quantity can similarly change corresponding to those grooves 32;The rear axis hole 69 can be stretched not through the rear cover 60, the rear spindle 38
The purpose for entering the rear axis hole 69 is the in fact rear heart in order to enable the swivel 30 that can more securely link together with the rear cover 60
Axis 38 can also be omitted and not set, and in this situation, which, which can also omit, does not set.
When using such as pneumatic impact spanner (not shown) of the pneumatic tool with the motor 1, user can set the air motor
To rotate forward or reversing, when high pressure gas (being more than 1 atmospheric pressure) imports in the cylinder 2, gas can enter via two air intake duct 24
In the room 22, in more detail, after gas first passes through two air inlet 62, then tri- tunnels Bing Fen, a part of gas is via this
Air inlet groove 42 flows into the room 22 (hereinafter referred to as flowing to A) after two, a part of gas enters after the two laggard conductance slot 66 again
Flow into the room 22 (hereinafter referred to as flowing to B), remaining a part of gas then (is hereinafter referred to as flowed into two air inlet runner 41
C), and then bis- tunnels Bing Fen again after flowing to the gas of C by two air inlet runner 41, a part of gas is via the air inlet before two
Groove 46 flows into the room 22 (hereinafter referred to as flowing to D), is left to flow again after a part of gas then enters the two advances conductance slot 56
Into the room 22 (hereinafter referred to as flowing to E);Wherein, flow to B and flow to E gas enter the room 22 after can blow those blades
34, make those blades 34 can be by being displaced outwardly and stick to the inner wall of the room 22 in those grooves 32, flowing to A at this time and flowing to D
Gas then push the blade 34 that those are stretched out, and then the rotor 3 is driven to be rotated in the room 22.
By taking rotating forward shown in Fig. 8 as an example, room 22 folded wherein between a blade 34a and adjacent blades 34b is hereby defined
For cavity C 1, folded room 22 is cavity C 2 between blade 34b and adjacent blades 34c, when high pressure gas via this two into
Air flue 24 enters in the room 22, blade 34a can be flowed to first the gas of B by the groove 32 towards it is extrapolated and stick in
The inner wall of the room 22, while blade 34a is blown by the gas for flowing through the rear air inlet groove 42 (flowing to A) and makes this turn
Son 3 starts to rotate clockwise, and blade 34b not yet passes the gas vent 28 at this time, after blade 34c does not also reach this
Exhaust groove 44;Fig. 9, Figure 10 are please referred to, with the rotation of the rotor 3, after blade 34b is by gas vent 28, chamber
Gas in C1 can be discharged via the gas vent 28 carries out first time exhaust, and it is recessed to reach the final vacuum by blade 34c Pu at this time
Slot 44, the gas in cavity C 2 can be discharged via the final vacuum groove 44 to carry out second and is vented, and when blade 34c is inside contracted
Can be by gas by squeezing into the final vacuum guide groove 68 in the groove 32, in other words gas can leave the appearance via two exhaust duct 26
Room 22, wherein the rotor 3 for each revolution, all circulation secondary the step of above-mentioned intake and exhaust.
In fact, gas is as follows via the detailed process that two exhaust duct 26 leaves the room 22, portion gas is first first
First time exhaust is carried out by those gas vents 28, then a part of gas is directly entered the final vacuum groove 44 by the exhaust outlet
64 discharges, a part of gas enter the final vacuum guide groove 68 then can be by before this by the exhaust outlet 64 discharge, other parts gas
Exhaust groove 48 and the front exhaust guide groove 58 are discharged by the exhaust outlet 64 again into the grate flow channel 43, and complete described second
Secondary exhaust.
Specifically, when user sets the pneumatic tool as reversion, gas can be by the external world through two exhaust
Road 26 enters in the room 22, and can be discharged to the external world through two air intake duct 24 by the room 22, that is to say, that two air intake duct 24
It is exchanged with the visual user's demand of function of two exhaust duct 26.
It is in elliptical cylinder-shape (i.e. section is oval) to be due to the room 22, when those blades 34 are stretched by the groove 32
It is that speed is relatively evenly retracted again when speed relatively evenly stretches out, reaches vertex, those blades 34 are stretched when going out or retracting
Indention journey more smoothes out, and shuttle speed is more uniform, first rapidly stretches out with blade in existing structure, emergency stop and about maintains again
Rapidly the stroke in retraction groove is different for a period of time, again on vertex, and the blade 34 in existing structure is opposite to be had and anxious accelerate, anxious slow down
Situation, in other words, the present invention is designed by the shape for changing room, have adjusted blade it is flexible when stroke characteristic or round-trip
When speed-time curve and the blade 34 and the groove can be reduced not only so that the movement of the blade 34 itself is more smooth
Frictional force between 32 wall surfaces further reduces the pivoting friction of the rotor 3, to promote the output power of the motor 1, and meanwhile it is each
Interelement smoothly interactive vibrations when also reducing motor operation, to reach the purpose of the present invention.In addition to this, due to horse
Up to the promotion of 1 efficiency, dealer can produce the air motor with existing structure same volume weight but outputting torsion bigger, or
Person has the air motor that torsion identical with existing structure exports but volume smaller, weight are lighter, great market potential.
In other possible embodiments, the design of two air intake duct 24 and two exhaust ducts 26 can change, for example,
Two air intake duct 24, two exhaust duct 26 can be located to the peripheral wall of the middle pipe 40, without passing through the protecgulum 50 or the rear cover 60,
The rotor 3 is pushed to rotate as long as high pressure gas can be imported in the room 22, and by the gas after promotion blade 34 by room 22
Middle discharge.For another example each air intake duct 24 can only by the air inlet 62, the one laggard conductance slot 66 and one, this be laggard
Gas groove 42 is formed, and does not include the air inlet runner 41, the preceding air inlet groove 46 and the advance conductance slot 56, so also
It may achieve the purpose of driving air motor rotation.Alternatively, each exhaust duct 26 can be only by 64, one final vacuum of exhaust outlet
Guide groove 68 and the final vacuum groove 44 are formed, and not comprising the grate flow channel 43, the front exhaust groove 48 and are somebody's turn to do
Front exhaust guide groove 58.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding change and deformations, but these corresponding changes and change in accordance with the present invention
Shape should all belong to the protection domain of appended claims of the invention.
