Abstract
237,209. Akt.-Ges. Brown, Boveri, et Cie. July 21, 1924, [Convention date]. Stop-gear.-The supply of steam to a turbine is reduced or stopped when abnormal distributions of steam pressure exist in the turbine. A valve k controlling leakage from the pressure oil system of the governor transmitting devices is positioned by pistons f, g which are subjected to the pressures obtaining at the points d, e in the turbine. When the relation of these pressures is normal the valve k is closed, otherwise the valve is opened and the throttle valve operated independently of the governor. Other forms of the operating means for the valve k suitable for other arrangements of turbine stages are described. In place of a valve k, the movement of the pistons f, g may be communicated mechanically to the governor or to an emergency stop valve.
