Abstract

A compressor comprises a motor-compressor unit of the volumetric type mounted by means of spring suspension assemblies within a hermetically sealed metal casing (5) composed of a casing body (6) and a cover (7). The casing (5) is of an asymmetric configuration having at any point thereof a double curvature of different magnitude relative to two ortogonal planes intersecting at the center axis (8) of the casing, with a substantially cambered lateral surface (9) of substantially eliptic cross-sectional shape. The audible noise emitted by the compressor is substantially reduced. <IMAGE>
