[New content] In order to eliminate or at least alleviate the problems encountered in the prior art, this design is designed to apply high torque to the work when reversing the unscrewing action, and to use the force during the positive and tight action. Pneumatic tool structure. The present invention is a pneumatic tool with a constant voltage limit, which mainly comprises a body, a cylinder and a rotor; the body is provided at the end of the plate for the action of tightening or unscrewing the work object. The gas red is set in the body of the gas, and the gas is provided with a positive airway, a first airway and a gas chamber, and the cylinder is provided with a positive air flow port connected between the positive airway and the air chamber, and a continuous connection By reversing the _ counter-wei tank of the neutron reduction chamber, the cylinder is opposite to the positive and reverse air passages - and there are several venting holes connected to the air chamber. The cylinder is provided with a dragon in the positive and negative holes. The paver is a rotatably arranged cylinder (4) and provides the effect of rotating the M295000 on the body of the rotor. The rotor is provided with a plurality of blades propelled by high-pressure gas on the circumferential side, and the gas system between the blades is borrowed. Relieve the pressure and release the gas outside, reduce the rotor torque. Other objects, advantages and novel features of the present invention will become more apparent from the detailed description and the accompanying drawings. [Embodiment] The techniques, means and functions used in this creation are described in the following. For better explanation, please refer to the detailed description. For the sake of explanation, the patent application is not subject to this. Structural limitations. Referring to the first to third figures, the present invention mainly includes a main body 1 , a cylinder 20 and a rotor 30 ; the cylinder 20 is provided with a plurality of steam pressure passages 25 and a plurality of voltage stabilizing passages 26 and 27 for making the cylinder 20 The gas is discharged to achieve the effect of limiting the torque of the rotor 3. Wherein: the body 10 has a handle 11 for holding, and a trigger head 12 is provided at one end for the purpose of tightening or unscrewing the work. The cylinder 20 is mounted in the body 10, and a cover 40 is respectively disposed at two ends of the gas red 2, and a wear-resistant piece 41 is further disposed between the cylinder 20 and the cover. The cylinder 20 is provided with a longitudinally extending positive air passage 21, a reverse air passage 22 and an eccentric air chamber 23. The cylinder 2 is further provided with a forward rotary groove 211' communicating between the forward rotary air passage 21 and the air chamber 23, and a reverse air passage 221 communicating between the reverse air passage 22 and the air chamber 23. Wherein, the size of the portion of the reverse air groove 221 communicating with the air chamber 23 is greater than the communication portion between the positive air transfer groove 211 and the air chamber 23 (as shown in FIG. 7 M295000). The cylinder 20 is provided on the side opposite to the positive and reverse air passages 2i, 22 with a plurality of exhaust holes 24 communicating with the air chamber 23. In the present embodiment, the exhaust holes 24 are biased toward the forward air passage. ! One side. The cylinder 2 is provided with two pressure relief passages 25 between the forward air passage 21 and the exhaust hole 24 (ie, the forward rotation position), and the pressure relief passages 25 provide less gas flow than the cylinders 2 The amount of gas supplied by the venting holes 24 is the amount of gas flow. The gas red 20 further defines a first plenum 26 between the forward air passage 21 and the pressure relief passage 25, and the first damper 26 consumes less gas than the pressure relief passages 25 The gas consumption of the person who consumes, in order to provide a regulatory effect. A second voltage stabilizing channel 27 is also disposed between the pressure relief channel 25 and the first voltage stabilizing channel 26, and the gas flux consumed by the second voltage stabilizing channel 27 is between the pressure relief channels 25 and The gas flow rate provided by the first plenum 26 prevents the intake air flow from being excessively large and provides a voltage stabilizing effect. In the present embodiment, the gas flow rate provided by the second plenum 27 is equal to the gas flow rate provided by the second plenum 26. • The rotor 30 is rotatably disposed in the air chamber 23 of the cylinder 2 to provide the effect of the body 10 rotating the head 12. The rotor 3 is further provided with a plurality of radially movable vanes 31 on the circumferential side. The vanes 31 are in contact with the inside of the air chamber 23 by the pushing of the high pressure gas, and drive the rotor 3 to rotate. Referring to the fourth figure, the state of the invention is reversed. When the high pressure gas (4) air passage 22 enters the air chamber 23 of the cylinder 20, it flows into the air chamber 23 via the reverse air passage 221. (The description is based on the Twelve-point M295000 clock direction above the drawing.) Since the reversed air groove 221 and the air chamber part extend from the eight o'clock direction to the eleven o'clock direction, the high voltage of the two communicating parts can be raised. The gas enters the plenum 23 to push the three points at ten o'clock and eight o'clock to drive the rotor 30 to reverse with high torque. The direction of the blade 舄 left thinker, the system is located at six or eight o'clock direction, the two blades w gas is still not exhausted outside the gas chamber 23, because of the position of the oxygen hole - 24 at the 6 o'clock direction, it still remains - The pressure drives the rotor 3 to reverse until the diaphragm 31 sweeps past the venting opening 24, and the gas exits the gas (4). In the process of unscrewing the work object, the effect of releasing the work object can be selected, and the work object is released and ugly, which is quite convenient to use. The milk is quickly rotated and is in the state of being used in the present invention. = When entering the air chamber 23 of the cylinder 2, it passes through the positive air chamber 23. Since the forward rotary vent is called the extension of the plenum 23 to the _clock direction (relatively reversed the vent 3, which is known to be short), the flow of gas into the plenum 23 is relatively reversed at two o'clock. Drive the rotor to rotate forward with a small torque of 乂圯. I gas will, as shown in the second figure) 'Push the high output of the blade 31 to the ^ / 乳 milk body through the first and second stable road 26, 27 release as a milk outside' at this time to prevent excessive intake , to achieve the design of the six-day and have a stable effect. That is, the blade 3J is subjected to high grinding gas, and the inside is lowered, so that the torque when the rotor 30 rotates forward is lower than that of 9 M295000 when the rotor 30 is reversed. /妾, when the rotor 30 continues to rotate forward and the blade 31 is swept over the pressure relief passage (as shown in the fifth figure), the high pressure gas that pushes the blade 31 will have a large amount of body discharged through the pressure passage 25 Outside the gas chamber 23, a complete release of C action is formed at this time to achieve a complete pressure relief effect. That is, the leaf 1 31 in the four o'clock direction almost loses the force propelled by the high pressure gas, so that the torque of the rotor 30 being turned forward is more significantly reduced. The gas between the two blades 31 in the direction of four or six o'clock is the fourth (four) Weikong 24 exhaust gas (four), and the other is located between six to ten, and the exhaust gas between the four blades 31 is released by the reverse air passage 22. To put it simply, when the rotor 3 is reversed, the two blades 31 are driven at six, eight, and ten o'clock directions, so that the effect of the large torque reversal can be obtained. When the rotor is rotating forward, since the pressure relief passages 25 and the condensing passages 26 and 27 exhaust the returning gas to the gas chamber 23, only one blade 曰 31 is driven to rotate + 3 两 in two o'clock direction. . In this way, during the process of tightening the work, the effect of rotating the work with a low torque is obtained, and the work object is not easily damaged after the work is tightened. As far as the above is concerned, it can be concluded that the creation has the following advantages: ^丨· The creation of the "pneumatic tool with constant pressure limit", wherein the size of the reversed gas groove and the gas chamber is greater than the forward rotation The communicating portion of the air groove and the air chamber is used to obtain a high torque when the rotor is reversed and a low torque when the rotor is rotated forward. 2. The "pneumatic tool with constant voltage limit and twist" of the creation, wherein the cylinder is provided with a pressure relief passage between the forward air passage and the exhaust hole to provide a pressure relief effect and to make the rotor rotate forward. Torque reduction. 10 M295000 3. The "Pneumatic Tool with Regulated and Twisted Torque" in this creation, in which the cylinder is also equipped with a first voltage stabilizer and a second stabilizer between the forward air passage and the pressure rail, and 4% The gas flow provided by the pressure passage is less than the gas flow provided by the uncompressed pressure to form a pressure release effect to achieve a voltage stabilization effect. From the point of view, this creation is extremely industrially useful, and there is no such thing as the same or similar creations appearing in domestic and foreign publications or in public use. It has already met the positive and negative requirements of the Patent Law and should be granted new patents. However, the above description is only a preferred embodiment of the present invention. When it is not possible to implement it, the number of tracks or the replacement of equivalent components, or the selection of the equivalent elements, Equal changes and modifications shall remain within the scope of this creation patent. ^ [Simple description of the map] The first picture: the three-dimensional appearance of the creation.
