<p>Electrical inductive apparatus, such as a transformer, cooled by a liquid dielectric having a boiling point within the normal operating temperature range of the apparatus. A vapor lift pump, with few or no moving parts, recirculates the liquid dielectric through a conduit which extends between a supply reservoir and a distribution point, by means of a pressure to velocity energy conversion provided by an orifice in a chamber located in the supply reservoir. The use of a vapor lift pump enables significant improvement in the reliability and power requirements of the apparatus.</p> |
