A rotary regenerator of the drum-matrix-type. The regenerator matrix is located and supported by two parallel rollers engaging the matrix rims at the inner or hot face of the matrix adjacent the bulkhead. The main seals are pivoted adjacent the drive rollers so that they can rotate to align with the matrix notwithstanding expansion and distortion. The angular position of the main seals is determined by aligning rollers engaging the outer or cold face of the matrix and mounted on the main seal frame. These are biased into engagement with the matrix by springs. The particular subject matter is improved structure of the main seals including the frame, roller mounts, cooling provisions, side seals, the secondary seal, and connection of the frame to the regenerator bulkhead.
