    Abstract: A compression system is disclosed having a compressor and a seal package including a non-contact seal and one or more radial shaft seals. In one form the non-contact seal is placed in proximity to a high pressure portion of the compressor. The offset of the non-contact seal from a shaft used to drive the compressor allows some amount of pressure reduced leakage air to pass. A radial shaft seal is coupled to the shaft axial aft of the non-contact seal on the other side of the compressor and oriented to discourage further passage of the leakage air past the radial shaft seal. A vent conveys leakage air to return to the compressor. A backup radial shaft seal can be used axially aft of the first radial shaft seal. A further radial shaft seal is disposed adjacent to the backup seal and oriented in the other direction to seal lubricant for a bearing.

    Abstract: The application is directed to a compressor having a housing with a fluid compression region to rotatably support a compressor rotor. The housing includes an inner wall formed as a thin wall positioned about the compression region and an outer wall spaced radially outward of the inner wall. A cooling chamber is formed in a space between the inner and outer walls. A rib formed on the inner wall projects into the cooling chamber to provide structural support and prevent thermal deformation of the thin inner wall during compressor operation.

    Abstract: Rotors for a rotary screw compressor having geometries that increase the efficiency of the compression process. The thermodynamic behavior of the rotors may be improved through an increase in the number of male and female lobes of the rotors and/or by an increased wrap angle, such as, for example, using wrap angles that exceed 360 degrees. By increasing the number of lobes, the rotors may have improved resistance to bending of the rotors that may otherwise occur when the temperature of the rotors is elevated and/or the rotor is utilized in relatively high pressure compression applications. The improved resistance to bending may allow the rotors to retain the relatively small size of the work spaces between intermeshed lobes of the rotors in which captured working fluid is being compressed.

    Abstract translation: 用于具有提高压缩过程效率的几何形状的旋转螺杆式压缩机的转子。 转子的热力学行为可以通过转子的凸形和凸形凸起的数量的增加和/或增加的包角（例如使用超过360度的缠绕角度）来改善。 通过增加叶片的数量，当转子的温度升高和/或转子用于相对高压的压缩应用中时，转子可能具有改进的转子抗弯曲性能，否则可能发生。 改进的抗弯曲性可允许转子在被压缩的捕获的工作流体的转子的相互啮合的叶片之间保持相对小的工作空间。
