Abstract
A cryosorption pump comprises a pump housing; a supply conduit merging into the pump housing for introducing sorption material thereinto; an outlet conduit opening into the pump housing at a location below and spaced from the supply conduit; a plurality of heat conducting wall surfaces disposed in the pump housing; a refrigerator operatively connected to the wall surfaces for cooling them to a cryogenic temperature to which the sorption material situated between the wall surfaces is exposed; a regenerator connected to the outlet and supply conduits for regenerating sorbent-laden sorption material received from the pump housing by means of the outlet conduit and for admitting sorbent-free sorption material into the supply conduit; a first conveyor arranged in the outlet conduit for advancing sorbent-laden sorption material from the pump housing into the regenerator; and a second conveyor arranged in the supply conduit for advancing sorbent-free sorption material from the regenerator into the pump housing.
