Abstract

1379978 Engine stop gear SOC SURGERIENNE DE CONSTRUCTIONS MECANIQUES 8 Feb 1972 [11 Feb 1971] 5685/72 Heading F1K The invention relates to an emergency stop device for an internal-combustion engine. The engine fuel supply system includes a reservoir 2 of liquid fuel, a primary pump 3 having a suction pipe 4 connected to the fuel reservoir and a delivery pipe 5, an injection pump 7 having a supply chamber 8 in which the delivery pipe terminates and which is connected to the reservoir through a calibrated valve 10 (called a scavenging valve) adapted to be opened when the pressure in the chamber exceeds a predetermined threshold and at least one injector 11 receiving fuel from the injection pump and introducing it into the engine. The device comprises a hollow body 14 which is arranged to receive the neck of a bottle 16 of pressurized gas normally closed by a fluid tight diaphragm 17, which body is connected through a first non-return valve 19 to a point of the delivery pipe situated downstream of a second non- return valve 21, and the device having a sudden action mechanism 22 adapted to pierce the diaphragm in case of an emergency and thus create in the portion of the delivery pipe 5 situated downstream of the point, and in the supply chamber 8 of the injection pump, a rapid and momentary flow of gas which displaces the fuel therefrom towards the reservoir 2 through the scavenging valve 10 and thus causes stopping of the engine. The sudden action mechanism which pierces the diaphragm is released with the aid of a detector (not shown) operated by the emergency condition such as uncontrolled running of the engine. The detector may be linked to the sudden action mechanism by an electromagnetic or fluid-pressure operated device. The sudden action mechanism may comprise a weight 23 movable between an armed position wherein it is loaded by a spring 24 and retained by a bolt 25 and a released position.
