Abstract (en)

[origin: EP0879967A2] The pumping machine assembly has a hot (1) and a cool (2) section, separated by a heat barrier as a pair of spaced flange plates (5,6) linked together by one or more force transmission metallic units (9). The bonding has a sufficient minimum cross section surface for the force transmission requirements. The two plates (5,6) are bonded together by a tubular body (11), surrounding the shaft (4) or a shaft bush (12), with a narrow gap between them. Ring recesses in one or both plates (5,6) hold force transmission units (9) and/or a thermal insulation material (15).
