Реферат: ABSTRACT OF THE DISCLOSURE The invention relates to a cryogenic liquid pump provided with a pump body driven by a motor assembly and integrated in a cryogenic liquid tank, wherein said pump body is removable and can be put selectively in communication with the tank by sliding in a well, a first non-return valve making it possible when in the open position to transfer liquid from the tank to the pump body prior to evacuation thereof in the form of a liquid or a gas via an outlet orifice, and a second non-return valve making it possible, when in the open position, to establish a flow of cold gas from the gas overhead of the tank towards a rear end of the pump body from which it is exhausted to the outside via a sweeping/venting orifice. Preferably said sweeping/venting orifice is provided at its outlet with a device for adjusting the flow rate of cold gas leaving the pump body.
Removable and self-cooled integrated cryogenic liquid pump.
