Abstract

Sistema di sospensione per un compressore ermetico a moto alternativo comprendente un alloggiamento ermetico (2) supportante entro di esso un'unità (1) a motore-pompa che è mantenuta in sospensione mediante molle elicoidali (3) le loro estremità essendo rispettivamente e simultaneamente fissate all'alloggiamento (2) e all'unità a motore-pompa (1). Secondo l'invenzione, è previsto almeno un elemento (10, 20, 30, 40, 50, 60) per assorbire energia vibratoria di alta frequenza, ed è fissato a ciascuna molla elicoidale e in stretto contatto con almeno parte della superficie del filo metallico della molla, lungo un'estensione di quest'ultimo, al fine di assorbire e smorzare la risonanza di propagazione longitudinale delle onde attraverso tutta la molla, senza variare le caratteristiche di elasticità della molla alle basse frequenze.Suspension system for a hermetic reciprocating compressor comprising an hermetic housing (2) supporting within it a motor-pump unit (1) which is kept in suspension by means of helical springs (3) their ends being respectively and simultaneously fixed the housing (2) and the motor-pump unit (1). According to the invention, at least one element (10, 20, 30, 40, 50, 60) is provided for absorbing high frequency vibratory energy, and is fixed to each coil spring and in close contact with at least part of the surface of the metal wire of the spring, along an extension of the latter, in order to absorb and dampen the resonance of longitudinal propagation of the waves through the whole spring, without varying the elasticity characteristics of the spring at low frequencies.
