<p>The refrigeration set has a compressor unit with a piston working in a cylinder and driven by a shaft, the unit being accommodated in a hermetically sealed housing. Connected to the housing is a housing accommodating an axial magnetic coupling between the driving shaft and that actuating the compressor piston. The coupling housing is hermetically sealed from the outside by a separator plate in the air gap between the two coupling magnets. The two shafts can each have plates, opposite each other, and supporting annular permanent magnets. The external magnet diameter can be less than that of the plates, the space between the magnets and the plate flanges being filled with synthetic resin.</p> |
