Abstract
A suction sound damper for a hermetically encapsulated compressor has a housing that is formed of at least an upper part (3), a lower part (1) and an insert (2), and having at least two chambers (7, 8) and a channel (9), connected thereto, leading from a lower inlet opening (10) to an upper outlet opening (11). The insert (2) has a side wall (18) which, together with a section (19) of the housing wall, forms a capillary gap (20) in which lubricating oil collects and is retained. This produces additional sound damping.
