A hermetically encased compressor comprising a casing (6) enclosing a motor-compressor unit (7, 8) supported therein by prop members (12) comprising, from the bottom of said casing upwards, a first cylindrical section (13) having a major diameter and a second cylindrical section (14) having a smaller diameter terminating in a frustoconical end portion (15) and being inserted into the lower end of a cylindrical spring (11) secured to the base of said motor-compressor unit. The relative dimensions of the various components are calculated with a view to reducing the noise generated by the suspension assembly during transient phases of the compressor. In particular, the laterral surface of the frustoconical portion (15) of each prop member is inclined at an agnle of 11<o> relative to the axis of the respective prop member. <IMAGE> |
