    • A kind of gear is provided with shorter teeth, transition teeth and at least one longer tooth. The cross-section of the longer tooth is of a hawk beak shape, and the profile of the longer tooth is smoothly connected in series by a convex section, a tip section, a concave section, and a leading section The two sides of the longer tooth are each provided with a transition tooth which neighbors a shorter tooth on the opposite side of the longer tooth. The pair of engaging gears according to this invention have advantages of reducing the fluid leakage, canceling the inertia of the rotors, and minimizing the vibration and noise. This invention also discloses a fluid machine for conveying, compressing or expanding liquid or gaseous fluids, which includes a casing comprising a housing, an upper end cover and a lower end cover. At least one pair of engaging gears which includes one driving rotor according to this invention and one driven rotor according to this invention is accommodated in the housing. As a result, the leakage between the rotors can be reduced, therefore the compression ratio can be improved. In addition, over compression and under compression can be avoided in operation.
    • 一种齿轮具有较短的齿,过渡齿和至少一个较长的牙齿。 长齿的横截面为鹰嘴形状,长齿的轮廓通过凸部,前端部,凹部和前端部分串联连接。两侧较长 齿各自设置有过渡齿,该过渡齿在较长的齿的相对侧邻近较短的齿。 根据本发明的一对啮合齿轮具有减少流体泄漏,消除转子惯性并使振动和噪声最小化的优点。 本发明还公开了一种用于输送,压缩或膨胀液体或气体流体的流体机械,其包括壳体,其包括壳体,上端盖和下端盖。 根据本发明的包括一个驱动转子和根据本发明的一个从动转子的至少一对啮合齿轮容纳在壳体中。 结果,可以减小转子之间的泄漏,因此可以提高压缩比。 此外,在操作中可以避免过度压缩和欠压缩。

    • Internal combustion engine includes a rotary oxidizing gas compressor, a constant volume combustion chamber with pneumatically controlled intake and exhaust valves and a fuel injector, and a rotary combustion gas expander. Each of the rotary compressor and rotary expander has a pair of tangential rotors dependently rotatable in a housing, one rotor having a vane and the other a notch for allowing passage of the vane, to form a fluid tight segmented annular region through which the vane moves. The respective one of the intake valve and the exhaust valve admits a mass of high pressure compressible fluid to the region through a triangular port for expansion or from the region after compression, the mass of fluid being confined in a part of the region between the vane and the surface of the notched rotor and changing in pressure because of the change in arcuate length and volume of the confined part. The respective pairs of rotors are included on the same respective shafts. Two vanes may be included on the one rotor and two notches on the other. Two vaned rotors may cooperate with one notched rotor, the vaned rotors being on separate shafts.
    • 内燃机包括旋转氧化气体压缩机,具有气动控制的进气和排气阀的恒定体积燃烧室和燃料喷射器,以及旋转燃烧气体膨胀机。 旋转式压缩机和旋转式膨胀机中的每一个具有可沿壳体转动的一对切向转子,一个转子具有叶片,另一个转子具有用于允许叶片通过的切口,以形成流体密封的分段环形区域 。 进气门和排气门中的相应一个通过用于膨胀的三角形端口或压缩后的区域将大量的高压可压缩流体接纳到该区域,流体的质量被限制在叶片之间的区域的一部分中 和切口转子的表面,并且由于限制部件的弓形长度和体积的变化而改变压力。 相应的转子对包含在相同的轴上。 两个叶片可以包括在一个转子和另一个凹口上。 两个转子可以与一个带槽的转子配合,这些转子是分开的。
