A water cooled steam jet for transferring fluid and preventing vapor lock, or vaporization of the fluid being transferred, has a venturi nozzle and a cooling jacket. The venturi nozzle produces a high velocity flow which creates a vacuum to draw fluid from a source of fluid. The venturi nozzle has a converging section connected to a source of steam, a diffuser section attached to an outlet and a throat portion disposed therebetween. The cooling jacket surrounds the venturi nozzle and a suction tube through which the fluid is being drawn into the venturi nozzle. Coolant flows through the cooling jacket. The cooling jacket dissipates heat generated by the venturi nozzle to prevent vapor lock.

[ I claim:] [1.] A cooled steam jet for transferring fluid comprising:a. a source of fluid to be transferred;b. a source of steam;c. a venturi nozzle comprising a convergent section, a diffuser section, and a throat portion disposed therebetween, said venturi nozzle being capable of producing a high velocity flow capable of creating a vacuum to draw the fluid from said source of the fluid to be transferred, said venturi nozzle being connected to said source of steam, said throat portion having a high velocity flow; andd. a cooling jacked disposed around said throat portion and said converging and diffuser sections of said veneturi nozzle, said cooling jacket having an inlet connected to said source of coolant and an outlet allowing said coolant to flow through said cooling jacket, thereby cooling said venturi nozzle to prevent vaporization of the fluid being transferred as the fluid is being drawn into said venturi nozzle.
