Abstract

866,867. Engine stop-gear. BROWN, BOVERI & CIE A.G. July 21, 1959 [June 28, 1958], No. 24975/69. Class 122 (4). A turbine overspeed trip device comprises a centrifugally-actuated striking pin 2 centred and supported in a transverse bore in the turbine shaft 1 by two spaced disc-shaped plate springs 3. The plate springs are fixed at their inner and outer peripheries respectively to the pin and to the shaft by nuts 7 and 4 respectively and are preferably of spiral form with the turns 10, Fig. 2, increasing in width with increase in spiral radius. The pin 2 is loaded to its inoperative position, as shown in Fig. 1, by a helical spring 9 and at overspeed the pin moves axially outward against the resistance of the spring 9 and the springs 3 to impinge on a latch (not shown) and cause the turbine stop valve to close.
