Abstract
Abstract Vibration and shock isolation, as well as working fluid flow path sealing in a turbine-type power plant having a turbine housing 18 with a radially directed peripheral outlet 38 is achieved by locating the turbine housing 18 within a tubular housing 44 with a radially inwardly opening port 46 aligned with the turbine housing outlet 38 and disposing elastomeric seal and turbine mounts 50, 52 mounted on spaced side walls 28 and 30 for sealing the outlet 38 to the port 46 and to serve as engine mounts for a turbine wheel 10 and the turbine housing 18.
