The invention is concerned with a safety device for a fuel driven engine which is lubricated by liquid lubricant under pressure. The invention is particularly concerned with such a safety device comprising a first operating member; a first spring acting on the first operating member to bias the latter into a first position; a pressure sensitive device adapted to be subject to the pressure of the liquid lubricant and being connected to the first operating member to move the latter from its first position to a second position when the pressure detected is more than a predetermined minimum; a second operating member normally movable freely relative to the first operating member from a first position to a second position; second spring means for biassing the second operating member into its first position; and detector means for detecting when a predetermined operation has taken place and for moving the second operating member into its second position when such predetermined operation has taken place. |
