5月參閲第四圖，高壓氣體流入缸室(25)時，係衝擊於前渦 輪(6〇)之葉片（62)，由於葉片之葉形之緣故，前渦輪將產生第 八圖所不之F方向之轉動，接著氣流復流向逆向輪(7〇)，並衝 擊於逆向輪之葉片（72)，使得逆向輪產生s方向；氣流接著流 向後渦輪(80)並衝擊其葉片（82)，後渦輪同樣以F方向轉動。 因此’該一渴輪(6〇)(8〇)及轉軸(5〇)係同向轉動；而逆向輪(7〇) 則反向轉動；前述之單向轴承(75)係確保逆向輪只能以s方向 轉動，使逆向輪與渴輪始终為不同的轉向。氣流於該三者 (60)(70)(80)間係連續的流動，最後，氣體復自排氣孔(34)排出 氣紅。In May, referring to the fourth figure, when the high-pressure gas flows into the cylinder chamber (25), it hits the blade (62) of the front turbine (6〇). Due to the blade shape of the blade, the front turbine will produce the eighth figure. The rotation in the F direction, followed by the reflow of the airflow to the reverse wheel (7〇), and impact on the blade (72) of the reverse wheel, so that the reverse wheel produces the s direction; the air flow then flows to the rear turbine (80) and impacts its blade (82) The rear turbine also rotates in the F direction. Therefore, the 'thirsty wheel (6〇) (8〇) and the rotating shaft (5〇) rotate in the same direction; the reverse wheel (7〇) rotates in the opposite direction; the aforementioned one-way bearing (75) ensures the reverse wheel only It can rotate in the s direction, so that the reverse wheel and the thirsty wheel always have different steering. The gas flow continuously flows between the three (60) (70) (80), and finally, the gas recirculates from the vent (34) to exhaust the gas red.
向壓氣體衝擊則滿輪(60)之葉片（62)促使前渦輪轉動後， 復經由葉片（62)之導引，流向逆向輪(7〇)而衝擊其葉片(72)，並 使逆向輪反向轉動。因葉片（62)與葉片（72)之葉形為反向，氣 流係形成一反向壓力衝擊於葉片（72)。同時，葉片（72)之容積 較渦輪(60)之葉片（62)之容積大，故氣流之壓力能有效的膨脹 推動逆向輪(70)，使其快速轉動。 接著，氣流復自逆向輪(70)流向後渦輪(80)，同樣的，該 二者(70)(80)亦為反向之轉動、葉片(72)與(82)之葉形相反，^ 及葉片（82)之容積大於葉片（72)之容積，故氣流以一反壓衝擊 後渦輪之葉片（82)，且氣體得以膨脹而推動葉片（82)，使得後 渦輪(80)具有相當的轉動動能。後渦輪之動能將回饋於同步轉 動之前渦輪(60)，增進氣缸整體之輸出動力。 復請參閱第五圖，缸體(20)於前渦輪(60)之位置，以流道 8 1327949 (30)為起點，沿著前難轉動方向依序具有_辅祕氣口⑽ 及二辅助排氣口(27)(28)，流道(3〇)係位於吸氣口(26)及第二排 氣口(28)間。於前渦輪(6〇)轉動之初，由於氣體未完全膨脹， f因轉速快，於吸氣口(26)之處將有外界的氣體被吸入缸室。 當轉動至排氣口(27)(28)時，因氣體已有所膨脹，而有些許氣 體自排氣口排出缸體。在前渦輪(60)之運轉行程中，於初始位 置(A)及終了位置(B)間係具有壓力差，此—壓力差係使前滿輪 易於產生轉動扭力。 缸體設置該等開口(26)(27)(28)時，氣缸即非密閉之空間， 可促^氣體流動之順暢性，因而降低渦輪於缸體内轉動時之阻 力，尚壓氣體之能量即不會損耗於對抗阻力，更有效率地驅動 氣缸。 又，外界氣體自吸氣口(26)補充入氣缸(1〇)時，係被氣把 所利用，故可減低氣缸對於高壓氣體之需求量，從而降低高壓 氣體之耗氣量。 一於軋缸作動時’該二渦輪_(8〇)及逆向輪(7〇)係相反方向 的兩速轉動，則渴輪轉動時施於轉軸之陀螺儀效應與逆向輪施 予轉軸之陀螺儀效應恰為反向硫消，達到平衡，該氣紅即不 會產生扭轉現象，保持穩定，可避免操作人員之疲累。 除了缸體之外，本發明之氣缸並無定子，而均為轉子(即 渦，與逆向輪），有別於習知氣缸。該反向轉動之逆向輪可增 進氣流之動能，提高氣缸之動力，且可防止氣動工具產生扭轉 現象。而喊π赫氣π使氣缸有效的發㈣動扭力，並 高壓氣體之耗氣量。 可理解的是，本發明不以裝設二個渦輪及一個逆向輪為 限，例如，可裝設三個渦輪及二個位於其間之逆向輪。 综上所述，本發明係為同類物品之首創，並具進步性功 9After the impingement of the gas, the blade (62) of the full wheel (60) causes the front turbine to rotate, and then passes through the guide of the blade (62), flows to the reverse wheel (7〇) and impacts the blade (72), and makes the reverse wheel Reverse rotation. Due to the opposite of the blade shape of the blade (62) and the blade (72), the airflow creates a reverse pressure impact on the blade (72). At the same time, the volume of the vane (72) is larger than the volume of the vane (62) of the turbine (60), so that the pressure of the airflow can effectively expand to push the reverse wheel (70) to rotate rapidly. Then, the airflow reverts from the reverse wheel (70) to the rear turbine (80). Similarly, the two (70) (80) are also opposite rotations, and the blades (72) and (82) are opposite in shape, ^ And the volume of the blade (82) is larger than the volume of the blade (72), so the airflow impacts the blade (82) of the turbine after a back pressure, and the gas expands to push the blade (82), so that the rear turbine (80) has an equivalent Turn the kinetic energy. The kinetic energy of the rear turbine will be fed back to the turbine (60) before the synchronous rotation, increasing the overall output power of the cylinder. Referring to the fifth figure, the cylinder (20) is located at the position of the front turbine (60), starting from the flow passage 8 1327949 (30), and has a _ auxiliary secret port (10) and two auxiliary rows along the front difficult rotation direction. The port (27) (28) and the flow path (3〇) are located between the intake port (26) and the second exhaust port (28). At the beginning of the rotation of the front turbine (6〇), due to the incomplete expansion of the gas, f is fast because of the high speed, and outside air will be drawn into the cylinder chamber at the suction port (26). When it is rotated to the exhaust port (27) (28), the gas has already expanded, and some gas is discharged from the exhaust port. During the running stroke of the front turbine (60), there is a pressure difference between the initial position (A) and the final position (B), which causes the front full wheel to be prone to rotational torque. When the cylinders are provided with the openings (26) (27) (28), the cylinder is a non-closed space, which can promote the smooth flow of the gas, thereby reducing the resistance of the turbine when rotating in the cylinder, and the energy of the gas. That is, it will not be worn out against resistance and drive the cylinder more efficiently. Further, when the outside air is replenished into the cylinder (1〇) from the intake port (26), it is used by the gas cylinder, so that the demand for the high pressure gas by the cylinder can be reduced, thereby reducing the gas consumption of the high pressure gas. When the cylinder is actuated, the two turbines (8 〇) and the reverse wheel (7 〇) are two-speed rotation in the opposite direction, and the gyro effect applied to the shaft when the thirsty wheel rotates and the gyro of the reverse wheel are applied to the shaft. The instrument effect is just the reverse sulfur elimination, reaching the balance, the gas red will not produce the torsion phenomenon, maintain stability, and avoid the fatigue of the operator. In addition to the cylinder, the cylinder of the present invention has no stator, but is a rotor (i.e., vortex, and reverse wheel), which is different from conventional cylinders. The counter-rotating reverse wheel increases the kinetic energy of the airflow, increases the power of the cylinder, and prevents the torsion of the pneumatic tool. And shouting π Hz π to make the cylinder effective (four) dynamic torque, and the gas consumption of high pressure gas. It will be understood that the present invention is not limited to the installation of two turbines and one counter-wheel, for example, three turbines and two counter-wheels disposed therebetween. In summary, the present invention is the first of its kind and has progressive merits 9
