The expression originates from the mechanical necessity of the steam engine, specifically the function of the relief valve. When the pressure within a boiler reached a level that threatened a structural explosion, the valve allowed the excess to escape into the atmosphere. The term describes this release of force, which prevented the total destruction of the engine by way of a controlled discharge.
