Abstract

1437669 Engine stop-gear SENTINEL DISTRIBUTORS INC 7 May 1974 [11 May 1973] 20150/74 Heading F1K I.C. engine emergency stop device comprises a valve A in the fuel supply lines 26 to the carburetter, the valve being held in the open position by oil pressure in a line 24 connected to the lubricating oil pump, the oil pressure being vented by either a valve B which opens if the engine coolant exceeds a predetermined temperature or a valve C, connected in parallel with valve B, if the coolant pressure drops below a predetermined pressure. Valve C comprises a valve disc 60 which prevents flow from inlet 36 to outlet 38 when it is in engagement with a seat 40. Coolant pressure acts on a diaphragm 64 and through rod 68 and spring 50 presses the valve disc on to its seat. If the lubricating oil pump output pressure falls or if either of valves B or C opens, the fuel supply is cut off.
