Abstract
Abstract A combustion liner suitable for an automotive gas turbine has variable primary and secondary air admission ports through the wall of the liner. The areas of these sets of ports are varied jointly by two annular valve sleeve assemblies reciprocable on the surface of the liner. Each valve sleeve assembly comprises an outer rigid ring, four approximately quarter-cylindrical valve plates extending around the outer surface of the liner within the ring and coupled to the ring for reciprocation by it, and a leaf spring disposed between the ring and each valve plate to hold the valve plate in contact with the liner.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
Means for controlling flow of hot gas comprising, in combination, a substantially cylindrical body defined by a wall with ports through the wall adapted for flow of hot gas from one surface of the wall through the ports to the other surface of the wall and slide valve means movable relative to the body to vary the area of the said ports, wherein the improvement comprises slide valve means including a movable actuating ring extending around the body overlying the surface which is upstream in the direction of flow through the ports; a circumferential row of part-cylindrical valve plates disposed between the actuating ring and the body configured to slide on the surface of the body to throttle the said ports variably; means coupling the valve plates to the actuating ring for concurrent movement; and spring means mounted between the actuating ring and the valve plates reacting against the ring and the plates to press the plates against the body.
Claim 2
Dependent Claim
