ABSTRACT:
An apparatus for detecting fuel vapors in a turbojet engine oil tank is disclosed which incorporates a device in the oil tank which senses the presence of fuel vapors in the oil tank. The device has a housing defining an inner chamber in which a piston is slidably located. An actuating cartridge is also located in the chamber between an end wall of the housing and the piston. The cartridge comprises a material which expands in volume when subjected to heat and one which produces an exothermic reaction in the presence of fuel vapors. The housing defines one or more orifices to enable the atmosphere within the tank to communicate with the actuating cartridge.
