Abstract (en)

[origin: WO8906317A1] A cryogenic condensation pump comprises a casing (1) inside which are mounted a reservoir (3) for the cryogenic agent-liquid nitrogen, a heat-carrying envelope (4) and a herring-bone screen (5) all together forming a radiation screen (3, 4, 5), and a pumping-out element (6). The reservoir (3) for the cryogenic agent and the pumping-out element (6) are provided with suspension tubes (9) and (10), respectively. Each suspension tube (9, 10) is provided, respectively, with units (11-a) and (11-b) for its fastening to the casing (1), and with units (12-a) and (12-b) for its fastening, respectively, to the reservoir (3) for the cryogenic agent and to the pumping-out element (6). The suspension tube (10) of the pumping-out element (6) is provided with a supporting bushing (37), whereas in the cap (7) of the reservoir (3) for the cryogenic agent is fixed an annular element (38) contacting with the supporting bushing (37). The casing (1) of the pump, the radiation screen (3, 4, 5) and the pumping-out element (6) are made of light metals.
