A cryogenic fluid system includes a vessel and a pumping system positioned for submerging within cryogenic fluid within the vessel. The pumping system includes an electric drive structured to move a pumping element within a pumping chamber to pump cryogenic fluid out of the vessel. A cooling jacket forms a heat exchange cavity about the electric drive such that heat is rejected externally of the storage vessel.

Cryogenic fluid system and method of operating same

A submersible pumping system in a machine system includes a pumping element, and a drive mechanism for actuating the pumping element. The drive mechanism has an electromagnetic element with a superconducting state at or below a critical temperature. A temperature control jacket and cooling mechanism are provided to pump heat from a heat exchange cavity to cool the drive mechanism to or below a critical temperature less than an ambient temperature in a cryogenic environment.

Machine system having submersible pumping system, and method

An expansion tank () for a vehicle cooling system () of an engine using a liquid coolant () includes a tank body () defining a first volume (V) containing coolant (), wherein the coolant defines a variable coolant elevation level (CEL) within the tank body. The tank body () also defines an upper volume () containing air. A bladder () is disposed in the tank body () and defines a second volume (V) containing air. The bladder () includes a flexible membrane () actuated by an actuator (). When the engine is stopped or is below a predetermined temperature, the flexible membrane () is moveable to a first position (FP) which lowers the coolant elevation level (CEL), and when the engine is started or reaches a predetermined temperature, the flexible membrane () is moveable to a second position (SP) which raises the coolant elevation level. A communicating line () is in fluid communication between the upper volume () and the second volume (V) to fluidly communicate air therebetween.

Expansion tank for vehicle cooling system

A first loop contains engine coolant passageways () and a first radiator (). A second loop contains a first EGR cooler (). A third loop contains a second EGR cooler (), a second radiator (), a charge air cooler (LP), a first valve (), and a second valve (). Valve () apportions coolant flow entering an inlet (A) to parallel flow paths, one including second radiator () and the other being a bypass around radiator (). The apportioned flows merge into confluent flow to both an inlet of charge air cooler (LP) and a first inlet (B) of valve (). Valve () has an outlet (C) communicated to an inlet of second EGR cooler (). The first condition of valve () closes a second inlet (A) to coolant flowing toward both the second inlet (A) and inlet (A) while opening inlet (B) to outlet (C). The second condition of valve () opens second inlet (A) to coolant flowing toward second inlet (A) and inlet (A) of the valve () while closing first inlet (B) of valve () to outlet (C) of valve ().
