  • Patent number: 9835169
    Abstract: Actuator devices useable to change orientation of one or more vanes, including an actuator rod and an actuator device body configured to allow the actuator rod to move along the axis inside the actuator device body, and having an inlet flange configured to allow a third fluid to enter a space between the actuator device body and the actuator rod, and an outlet flange configured to allow the third fluid to exit the actuator device body. Besides providing a fluid seal between the first fluid and the second fluid, the third fluid may also heat the actuator rod thereby preventing ice formation.

  • Publication number: 20150330404
    Abstract: Sliding pads are installed at several convenient locations of a rotary machine comprising barrel casing, typically in the areas adjacent the external gasket on the outer diaphragm bundle periphery. The sliding pads, made of self-lubricating material, cast iron or others graphite filled materials, will be bearing the whole diaphragm bundle weight preventing any direct contact between barrel casing internal surface and diaphragm bundle external surface, both during assembly operations and also after the diaphragm bundle has reached its final location inside the barrel casing. In this way, it is possible to prevent possible damages to both diaphragm bundle and casing housing surfaces during diaphragm bundle insertion/extraction phase into/from the barrel casing.
