Device a vaporization of helium ii, in particular used for carrying the objects is very low temperature

摘要

P cryogenic device for carrying the objects to be very low temperatures, in which, by application of the action of the barrier effect of the thermomechanical superfluid helium ii coming from a storage tank is converted into steam, by means of a throttle element with a narrow passage, and passes into an exhaust pipe in which a vacuum can be. The throttle element is made in the form of a valve with a valve element can be moved with respect to a sleeve of the valve, the valve member and the sleeve forming the two of them, in the range of adjustment valve, a passage gap width of less than 10 mu and whose length can vary in the range of adjustment, the adjustment of the flow of the output of the valve takes place by modifying the length of the gap. / p
