Abstract

1,249,262. Overspeed safety devices for diesel engines. ROBERT BOSCH G.m.b.H. March 19, 1970 [March 19, 1969], No.13312/70. Heading F1K. An overspeed safety device for a diesel engine, fitted with a fuel injection pump having a highpressure 14 and a low-pressure chamber, comprises an electromagnetically operated safety valve 20 which is connectible between the high- and low-pressure chambers and which is actuated by a signal from a speed measuring device 17 responsively to the engine speed exceeding a maximum permissible value. The safety valve may be connected to the inlet bore 24 of the highpressure chamber or in a live leading from the high-pressure chamber to the low-pressure chamber.
