Abstract
A rotary regenerative heat exchanger including a rotatable disc-like matrix having an end seal comprising an arcuate portion and a diametral or chord-wise portion each comprising a pressure plate engaging the adjacent end face of the matrix and an axially-compressible resilient member acting between the housing of the heat exchanger and the pressure plate and defining a space internally of the seal portions communicating with a gallery defined by the housing and arranged to receive a pressurized fluid, the pressure plate of the transverse portion being compressively stressed between spaced parts of the pressure plate of the arcuate portion under cold conditions and the length of the pressure plate of the transverse portion being such that the pressure plates of the seal portions are substantially stress-free under hot working conditions.
