CRYOSTAT FOR MAGNETIC SUSPENSION VEHICLE Russian patent published in 1996 - IPC

FIELD: transport; magnetic suspension vehicles. SUBSTANCE: inner low-temperature vessel 1 is divided by partition into lower chamber 5 with superconducting magnet 9 and upper chamber 6 connected by throttling valve 10, check valve 11 and shutoff valve 12. End of inlet connection 13 of cryostat is located in lower chamber, and end of tubular heat exchanger embracing the screen and lower chamber, is connected with upper chamber. Throttling of gas in inner low-temperature vessel makes it possible to liquefy gas passing from lower chamber, accumulate liquid cooling agent in upper chamber and subsequent by discharge liquid through check valve from upper chamber into lower chamber. Level of liquid in lower chamber rises, thus providing cooling of superconducting magnet, and temperature of liquid gets reduced. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
