摘要： A rotary machine has stationary upper and lower housings with circumferential grooves and a rotatable component, as well as annular sealing segments movable toward and away from the rotating components between large and small clearance positions. To prevent circumferential displacement of the lower side segments by gravity forces and to enable the lowermost segment in the lower housing to move vertically between inner and outer clearance positions, the side segments of the lower housing are supported by brackets resting on a support surface forming part of the horizontal midline at the juncture of the upper and lower housings. Consequently, the gaps between the lower ends of the side segments and the opposite ends of the lower segment in the open position of the segments remains, enabling the lower segment to move radially vertically inwardly upon closing the seals.
