Abstract
1,048,332. Vacuum pumps. BALZERS PATENT-UND LIZENZ-ANSTALT. April 2, 1965 [April 17, 1964], No. 14016/65. Heading F1N. [Also in Division F4] In a vacuum pump, Fig. 2 (not shown), wherein gas to be evacuated from a receptacle 20 is condensed on the exterior surfaces of a closed metal shell 19, the shell is cooled by a closed circuit gas refrigerating plant disposed therein and comprising a compressor 21 supplying compressed gas through heat exchanger tubing 36, 40 to an expansion engine 24 which delivers cold low pressure gas to a chamber 43 located at the bottom of the shell. After taking up the heat of the condensing gases the gas e.g. helium, neon or hydrogen in the chamber 43 flows past the heat exchanger tubing 40 to the compressor inlet 46. The tubing 36 is cooled by liquefied air in a surrounding bath 35. The compressor 21 has a piston 22 driven partly by the working piston 27 of the expansion engine 24 and partly by an electric motor 33 disposed outside the shell 19. The compressor and expansion engine may be driven separately and the compressor may be mounted outside the shell. In a second construction part of the gas is expanded in the engine and part is expanded by passage through an expansion valve leading to the chamber 43 where it collects in liquefied form.
