Abstract

The invention relates to a gap regulating device for a rotor housing of a turbomachine, comprising a number of housing segments (1) combined to form a ring, and a number of actuators (2) for actuating the housing segments (1) in the radial direction. A rocker arrangement (5) is used to transfer the actuating movement of each actuator (2) to the associated housing segment(s) (1). The housing segments (1) preferably consisting of sinter material are pre-tensioned for an expansion of the ring. The springs (4) required therefor are built into the housing segments and elastically connect two respective adjacent housing segments to each other.
