Abstract (en)
[origin: WO2009067992A2] The invention relates to a gap regulating device for a rotor housing of a turbomachine, comprising a number of housing segments combined to form a ring, and a number of actuators for actuating the housing segments in the radial direction. A rocker arrangement is used to transfer the actuating movement of each actuator to the associated housing segment(s). The housing segments preferably consisting of sinter material are pre-tensioned for an expansion of the ring. The springs required therefor are built into the housing segments and elastically connect two respective adjacent housing segments to each other.
