ABSTRACT:
The inner compartment of a compressor for noxious fluids is isolated by means of the closure system when the compressor is stationary and disengaged from its driving means. The closure system is controlled by a magnetic attraction system, the external surface of which is uniformly constructed of magnetic material having a small thickness at the level of non-magnetic elements. A particularly noteworthy application of the system is in motor-compressor sets for the transfer of toxic and hazardous fluids employed in the nuclear engineering field.
