Abstract
The invention recites a microturbine system comprising a housing and a turbine including a rotary element having a shaft supported by the housing and rotatable about a rotary axis. A starter wheel is coupled to the shaft and rotatable in response to a stream of high-pressure fluid flowing from a high-pressure flow path. A pump is operable to provide a supply of lubricating fluid. The engine further includes a starter valve receiving the supply of lubricating fluid and being selectively operable to provide one of the stream of high-pressure fluid to the high-pressure flow path and a stream of low-pressure fluid to a low-pressure flow path.
