Title: Improvements in and relating to turbine type starters for internal-combustion engines
Inventor: GRAHAM DOUGLAS HARRY
IPC: F02C7/26
Filed: 1948-03-08
Abstract: 652,472. Turning gear. BRITISH THOM: SON-HOUSTON CO., Ltd. March 8. 1948, No. 7124. '[Class 7(v)] [Also in Group XXVI] In a turbine-type starting-motor for internal-combustion engines, including gas turbine power plant, having a bladed turbine wheel A adapted to be driven by a stream of gas under pressure, the wheel is mounted so that it can be moved into the path of the gas by the force of torque reaction exhibited by the engine and out of the gas path, to prevent over-speeding, by a spring-loaded member, such as fork F, in opposition to the force set up by the torque reaction. The wheel A with blades B is carried in bearings mounted in the fork F, the latter having shafts J which provide pivotal mounting for the fork assembly An output gear H is mounted coaxially with shafts J and is in constant mesh with a gear G on the starter outputshaft. To' prevent over-speeding of -the wheel A, the fork assembly is pivoted so that the blades B can move to a reduced torque position almost out of the gas stream emanating from a nozzle C. The pivotal movement may be effected by either manual means, a centrifugal device, a stretching disc as in Specification 624,223 or an electric solenoid. Stops are provided to limit the movement of the fork. The turbine wheel, when stationary, is held nearly out of the gas stream by the spring-loading of the fork, so that when starting takes place, the torque applied to the starter drive is small, thus allowing a smooth engagement of the drive with the engine. Torque reaction from the gear or the starter-turbine shaft then overcomes the spring-loading of the fork and causes the latter to swing the turbine wheel to a position where it is subjected to the full gas-flow. After the engine has been started, the removal of the load from the starter causes the torque reaction to disappear and the turbine wheel moves to the low-torque position thus reducing the speed to which the unloaded starter can attain. The gas is obtained from an electrically operated cartridge, and it may be arranged that the firing switch can be operated when the turbine wheel is in the low-torque position. The ratio between the low and full torque values is equal to the ratio between the inertia of the starter and, that of the starter plus engine.
