ABSTRACT:
An engine fuel flow shut-off system particularly adapted for off-highway dumper trucks includes a shutoff valve interposed in the fuel supply conduit to the truck propulsion engine and which is responsive to a pressure fluid control circuit to close. Compressed gas charge bottles operable from the operator's cab and from a ground position in proximity to the vehicle boarding ladder supply pressure fluid to the valve actuator to provide closure of the valve and closure of a second valve to interrupt engine lube oil pressure to an engine injector system governor. The vehicle on-board fire extinguishing system is also operably connected to the shutoff valve actuator by way of separate pressure fluid sources to effect closure of the fuel shutoff valve upon actuation of the fire extinguishing system from either the operator's cab or the ground position.
