ABSTRACT:
Apparatus associated with a component part of the drive system of a turbine assembly reduces the power applied to its drive rotor in a direct and substantially instantaneous response to the speed of its rotation rising to a predetermined level. A turbine starter for an engine embodying this apparatus comprises a housing for its rotor and the drive system of which it forms a part, a flow path for a gaseous fluid, delivered from a source, to power the rotor and a control device in connection with the drive system a component part of which moves radially thereof and, when its speed of rotation rises to a predetermined level, triggers a substantially simultaneous restriction of the flow path through which fluid can be applied to power the turbine rotor, thereby to produce a resulting reduction of the speed of rotation of the turbine drive system. If under such conditions the starter is engaged with a related engine, it will automatically disengage. The apparatus inherently and automatically prevents the occurrence of a speed of rotation of the turbine drive system which might induce self-destruction and explosive fragmentation of its housing and/or its component parts. The construction and arrangement of the control apparatus is such that the components thereof automatically reset once the speed of rotation of the starter drive system is interrupted or falls to a safe level.
