Description: |
| Abstract:
In apparatus wherein the fuel supply is cut off by a valve upon failure of the pressure of the lubricant supply, a dashpot is provided to delay the operation and manual or foot operated means are provided for opening the valve. A plunger 12 is subjected to the lubrisating-oil pressure passing through passages 13, 14 and is provided with a recessed part 25 which permits the flow of fuel through the passages 15, 16 in the position shown. The plunger has a head 19 which slides in a cylinder closed at the bottom by a plug 22 and open at the top to the fuel passage 15 through a restricted passage 21, or through a non- return valve 29 with restricted passages 30 in its body or in the valve seat. The head 19 is recessed to receive a spring under compression. When starting, a lever 28 engages a rod 17 secured to the plunger and depresses it. The plunger rises slowly owing to the dashpot until the pressure of the lubricant arrests it. Should the pressure fail, or build up too slowly, the fuel supply will be cut off. |
