Beschreibung
Zusammenfassung:	Suspension spring for a refrigeration compressor of the type which comprises a shell and a block, forming, with the stator of an electric motor, a stationary assembly which is mounted in the interior of the shell by means of an assembly of helical springs. The helical spring presents, for a predetermined dimensional range of one of the spring parameters defined by the spring average diameter, the pitch of its coils, the spring wire diameter and the active height, a ratio between at least two of each pair of the other three parameters, defined to provide, to said helical suspension spring, for a desired frequency band, a stiffness corresponding, at minimum, to that of structural reliability of the suspension, and an attenuation in its acoustic transmissibility, in relation to the springs dimensioned only as a function of their suspension structural requirements for a desired frequency band.
