Description of the invention (/) The field of surgery The present invention is roughly related to pneumatic tools. Of particular relevance to the present invention is a pneumatic tool ' with a reversible valve which has an overdrive gear for variable torque and speed. Related Art So far, various types of reversible valves, such as impact wrenches and pulse tools, have been used in pneumatic tools. For example, U.S. Patent No. 5,083,619, issued to Giardino et al. And assigned to Chicago Pneumatics, discloses an iron core reversible valve for reversing the direction of a motor in an impact wrench. A US patent No. 3,714,994 issued to Zoerner et al. And transferred to Gardner-Denver also discloses a reversible rotary valve. Also, refer to, for example, U.S. Patent No. 3,586,466 issued to Erickson, for a related technical field including an overspeed reversible mechanism for a hydraulic motor. All patent documents referred to herein are hereby incorporated by reference. One disadvantage of pneumatic tools is their ability to obtain various torques and speeds in the forward and reverse directions of the same tool. This is important for the construction, destruction or repair of large structures such as bridges. For example, one of these long-standing and under-appreciated issues is to provide enhanced torque and speed for removing lug nuts that are affected by corrosion, dirt or paint. Basically, a staff member will have two impact wrenches. The small impact wrench is mostly used for a lug nut 'so that the user does not feel tired and easy to operate. Large impact wrenches are used to remove more difficult lug nuts. Like this—a kind of large impact 3 This paper size applies Chinese National Standard (CNS) A4 (210 X 297 public love) (Please read the precautions on the back before filling this page) -JI f ϋ I n Intellectual Property of the Ministry of Economic Affairs Bureau staff printed A7 _B7__ Cooperatives V. Invention Description (>) The wrench is not only heavy and cumbersome, so it is only needed when removing the more laborious lug nuts. In addition, if it is only occasionally necessary to remove the more laborious lug nuts and carry two types of impact wrenches for backup, it is indeed a waste of time and inefficiency. So far, hydraulic motors with various torques and speeds have been disclosed. However, there are many disadvantages when using hydraulic devices as hand tools. For example, hydraulic tools maintain problems such as heat generated by friction. Another disadvantage is that the hydraulic fluid must be contained in a sealed system. If the hydraulic system is not adequately sealed, hydraulic fluid will leak from the system and cause slippery fluid to leak to the surface of the tool. Another disadvantage of hydraulic systems, as disclosed in U.S. Patent No. 3,586,466, is that when the torque increases, the speed decreases. This is because pressurizing the incompressible liquid in a single compartment between the rotor and the casing causes the rotor to rotate at a first speed and torque. However, when the two chambers are pressurized, because the hydraulic flow system is incompressible, the rotor will rotate at an increased torque and an increased speed without filling an area. In contrast, when air is affected by an enlarged area, it rapidly expands to fill the entire area. Therefore, pressurizing two cabins with air can result in an increase in torque and an increase in speed. A useful similarity is when a balloon filled with air is blasted with a needle tip. This is because the air in the balloon is compressed and quickly reaches equilibrium with the surrounding air. In contrast, when a balloon filled with water is poked, it does not burst but leaks slowly. This is because the water is not compressed. Relevant technologies provide pneumatic tools with reversible valves and hydraulic motors with different speeds and torques, but none of them have a reversible valve. 4 This paper is sized for China National Standard (CNS) A4 (210 X 297 mm) Li) (Please read the precautions on the back before filling out this page) Order: ： ----- · ---- line-.

Description of the Invention (々) The reversible valve has different speeds and torques, that is, overspeed gear. This kind of device is necessary to solve the problem that has been in the power tool industry for a long time and has not been sufficiently taken into account. Abstract: One advantage of the present invention is to overcome the drawbacks mentioned previously. To achieve this, the present invention provides a pneumatic tool comprising: a housing;-a rotor installed in the housing and rotatable; an output shaft connected to the rotor during operation; defined in the housing A pressure chamber between the rotor and the rotor; and a pneumatic reversible valve coupled during operation to control the rotor. The pneumatic reversible valve has an overspeed gear that provides increased torque and increased speed to the output shaft. In addition, the present invention provides a reversible valve for a pneumatic tool having: a housing; a rotor rotatably mounted in the housing; and a pressure chamber defined between the housing and the rotor, The pneumatic reversible valve includes an overspeed gear for the increased torque and increased speed of the rotor. An advantage of the pneumatic tool of the present invention is the ability to obtain increased torque and increased speed in the same tool. This is useful for problems such as the construction, destruction or repair of large structures such as bridges. A further advantage of the present invention is that it does not have the problem of a hydraulic device. Pneumatic tools do not increase temperature and heat like hydraulic devices. Instead, air flows through the tool to cool it due to expansion, which causes the tool to cool itself. In addition, pneumatic tools do not require closed systems like the inherent sealing problems inherent to hydraulics. Air enters a pneumatic tool through an inlet and is vented to the atmosphere through an exhaust. There is no leakage problem in general pneumatic tools. Because 5 paper sizes are applicable to China National Standard (CNS) A4 specifications (210 X 297 public love) ^ ------------------ line · I, (Please read the back Please fill in this page again) A7 ____B7__ 5. Description of the invention (>) Therefore, a pneumatic tool does not need a complicated sealing structure like a hydraulic motor. Another advantage of pneumatic tools is that when the torque increases, then Speed also increases. Another advantage of the present invention is that it allows the direction of the motor to be controlled and the forward and reverse directions of the overdrive gear. Another advantage of the present invention is that the reversible valve system can be used in different forms. For example, the reversible valve may be an iron-core suction valve or, preferably, a rotary reversible valve. Alternatively, a valve in the form of a combination of plunger and reversible rotation may be used. A rotary reversible valve of the present invention may include a rotatable flat element including at least three penetrating holes. The opening of the rotatable flat element directs air through a variety of fabric configurations, which allows selective delivery of compressed air to one or more ports. For example, the opening may be a T-shaped, Y-shaped, or a γ-shaped configuration together with an additional opening between the upper opening (such as an or flat flag shape). Another feature of the rotary reversible valve of the present invention is that when the reversible valve is in the form of a rotatable flat element, the valve includes a housing that extends beyond the motor and allows the operator to position it for rotation Way positioning grip. A pneumatic tool according to the present invention includes a pressure chamber defined between the housing and the rotor for providing an overspeed feature. Each pressure chamber contains a pressurized air to drive the motor 6 in a forward direction (please read the precautions on the back before filling out this page) ------- Order · ----- --- line | Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper is sized for the Chinese National Standard (CNS) A4 (210 X 297 mm) 401332 A7

Description of the invention (β) Inner casings 30 to restrict the openings into the motor casing 9. The valve housing 12 is sealingly (not shown) attached to the back of the motor housing 9 by bolts to provide compressed air through the opening 14 as shown in the fourth figure. A comparison of ten figures illustrates that the number of pressure chambers 19 provided to drive the motor 50 can be changed to adjust different size rotors, higher or lower speeds, and larger or smaller torques. However, for the sake of simplicity, the invention will hereinafter be described mainly with reference to a housing having two pressure chambers. As shown in the ninth figure, in order to constitute the pressure chamber 19, the surrounding periphery of the inside of the motor case 9 has staggered spaced recesses 15 and a cylindrical surface portion 16. When the rotor 50 is located inside the motor housing 9, pressure chambers 19A and 19B are defined between the rotor 50 and the recessed portion 15. In other cases, the rotor 50 rotates while seated in the cylindrical surface portion 16. The rotor 50 is driven by pressurized air entering through one or more of the mouths 35 to 38 formed in the motor housing 9. The pressurized air entering through the ports 35 to 38 rotates the rotor by moving a plurality of blades 54 located in the radial extension groove 52 of the rotor 50. What I understand is that although only eight blades 54 are shown in the drawing, it is also possible to use more or fewer blades. The fan blade is deflected outward by compressed air and centrifugal force transmitted to the innermost portion of the groove 52. Regardless of whether the fan blade 54 is inside the cylindrical portion 16 or the pressure chamber 19A_B, the outer end portion of the fan blade 54 is kept in contact with the inner periphery of the motor housing 9. In order to allow the compressed air to dissipate to the atmosphere, a copy of 10 paper sizes is provided around the periphery of the rotor compartment. It is applicable to China National Standard (CNS) A4 (210 x 297 mm). -------- 'Private -------- Order: --------- line-fs ^.

Description of the invention The exhaust port extends into the valve housing 12, as shown at 13A. Regarding the motor itself, each of the pressure chambers 19A and 19B includes two parts: the first ports 35 and 37 and the second ports 36 and 38. The first and second ports of each pressure chamber are located at opposite ends of its compartment. In order to guide the pressurized air to the ports 35 to 38, as detailed in the eleventh to thirteenth drawings, an inner casing 30 is arranged on the back of the rotor chamber 51. The inner casing 30 includes a plurality of openings 31-34 that allow pressurized air to pass through the valve casing 12 to the ports 35-38. The inner housing 30 is also provided with a bearing 72 provided with a steel ball 73 for supporting a shaft of the rotor (not shown). In addition, as shown in Figs. 12 and 13, the inner casing 30 is also provided with a circular lip end 39 which extends rearwardly into the valve casing 12 to rotationally guide the valve 20. This is discussed below. In operation, when the pressurized air passes through the openings 31 and / or 33 of the inner casing, respectively, the first ports 35 and 37 of the pressure chambers 19A and 19 B are either collectively in a first direction unless they are alone. The rotor is driven internally (for example, in a forward clockwise direction as shown in the eighth figure). Similarly, when the pressurized air passes through the openings 32 and / or 34 of the inner casing 30 respectively, the second ports 36 and 38 are jointly in a second direction (for example, as in the eighth The counterclockwise direction is not shown in the figure) to drive the rotor. When both ports contain pressurized air, the tool will be in an overspeed state.

Description of the invention ('ϋ) Overspeed selection valve 20 to determine which inner casing opening 31 ~ 34' and therefore which pressure chamber 35 ~ 38 The received air can be received from the valve housing I2. As shown in Figs. 5 to 7, the valve for a motor having two compartments may take various forms without departing from the scope of the present invention. Generally, the valve 20 has a rotatable flat element 18 containing a perforated protruding area 21 and a handle extension 29. As shown in the second to fourth figures, the valve 20 is a valve housing manifold 70 rotatably seated on the valve housing 12. A sealing material 100 closes the flat element 18 inside the valve housing manifold 70, and a sealing material 11 closes the handle extension 29 in a handle cavity 74 on the rear of the valve housing 12. in. After the valve housing manifold 70 is closed with sealing materials 100 and 110, the valve housing can receive the pressurized air introduced into the rotor 50 through the inner housing 30 and the valve 20, and then accommodate the valve housing through the opening 4 in vivo. Therefore, an operator can adjust the valve, and the handle extension 29 includes a handle 22 for rotating the valve described above on an outer portion of the valve housing. To guide the compressed air from the valve housing manifold 70, the valve 20 needs to be rotatably supported around the rounded lip end edge 39 of the inner housing 30. Each of the perforated protruding areas 21 on the valve 20 includes a perforated 25 to 27 extending through the flat member 18 and the protruding area 21. By rotating the valve 20, the perforations 25 to 27 can be aligned with the openings 31 to 34 of the inner casing to selectively transmit pressurized air to the selected port 35 through the openings 31 to 34 of the inner casing. 38. To adjust the drive of the motor by using compressed air through only one port, at least one perforation 27 must be positioned in order to determine the position of the valve. 12 This paper size is applicable _ National Standard (CNS) A4 (210 X 297) g) (Please read the precautions on the back before filling this page) Ί ------ Order: ------ line— 40ί332 A7 _______B7____ V.

In addition, in order to adjust the characteristics of the overspeed gear by transmitting compressed air through two ports, at least two penetration holes 25 and 26 on the opposite side and equal distance from the valve shaft must be provided. As shown in the three figures, in the position of the reversible overdrive, the valve perforations 25 and 26 are aligned with the inner housing perforations 32 and 34, respectively, to transmit the compressed air to the second ports 36 and 38. As depicted in the fifth to seventh figures, once the protruding perforated area 21 is positioned, the perforations 25 to 27, 125 to 127, and 225 to 227 can be changed accordingly. Changing the positioning of the perforation can change the position of the handle 22 of the valve. For example, as shown in the first figure, the valve 20 in the fifth figure can be provided with a specific position by being provided with a large perforated region 21 having a raised shape. In the sixth figure, the valve 20 includes four perforations 125 to 128 arranged in a roughly γ-shaped configuration, and the fourth perforation is arranged in the form of the same distance as the branch above the γ-shaped ( (I.e., in the shape of an or flat flag). In the seventh figure, the valve 220 includes three perforations 225 to 227 in a substantially T-shaped configuration. The number of perforations in the valve and therefore the number of positions that the valve can reach is determined by the number of chambers in the motor. In the two-chamber motor depicted, the valve 20 shown in the fifth figure can be positioned in at least four positions; for example, in the first position, the valve perforation 27 and the inner casing opening 31 Is pneumatically connected to drive the motor in the direction of advance through the first port 35; in the second position, the valve perforation 27 and the inner housing opening 34 are pneumatically connected to pass through the second port 38 and drive the motor in a reverse direction; in the 13th paper size the Chinese National Standard (CNS) A4 specification (210 X 297 public love) < Please read the precautions on the back before filling this page) -· ^ ----------- · ----- ^ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ______B7 ______ V.
