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.
Claims18
A power plant comprising a turbine wheel rotatable about an axis;
- a transmission engaged with said turbine wheel;
- a turbine housing containing and journalling said turbine wheel and having a radially directed peripheral outlet including two axially spaced side walls;
- a tubular housing containing said turbine wheel, said transmission, and said turbine housing and including a radially inwardly opening port aligned with said outlet;
- and
- elastomeric means of low stiffness mounted on said spaced side walls for (a) sealing said outlet to said port, and (b) serving as an engine mount for mounting said turbine housing, and thus said turbine wheel, to said tubular housing.
A power plant comprising a turbine wheel rotatable about an axis;
- a transmission engaged with said turbine wheel;
- a turbine housing surrounding said turbine wheel and having a radially directed, peripheral outlet including two axially spaced side walls;
- a tubular housing containing said turbine wheel, said transmission, and said turbine housing and including a radially inwardly opening port aligned with said outlet;
- and
- a pair of low stiffness, elastomeric seal and turbine mounts, one on the radially outer extremity of each of said walls, sealing the associated wall about said port, each said seal and turbine mounting including a sealing surface engaging said tubular housing and a groove oppositely of said sealing surface and receiving a spring ring for biasing said sealing surface toward said tubular housing, a mounting end secured to the associated wall and an intermediate flexing section comprising at least one fold.
A power plant comprising a turbine wheel rotatable about an axis;
- a transmission engaged with said turbine wheel;
- a turbine housing surrounding said turbine wheel and having a radially directed, peripheral outlet including two axially spaced side walls;
- a tubular housing containing said turbine wheel, said transmission, and said turbine housing and including a radially inwardly opening port aligned with said outlet;
- and
- a pair of elastomeric seal and turbine mounts, one on the radially outer extremity of each of said walls and extending peripherally thereabout in sealing contact with said tubular housing about said port, each seal and turbine mount including at least one pressurizable chamber for receiving a fluid under pressure to bias the corresponding seal and turbine mount into said sealing contact.
