Abstract
ABSTRACT
In a refrigerator comprising a capsule having a motor compressor, a suction connector (4) passing through the capsule wall (1) terminates at a spacing from the inlet orifice (6) of a suction conduit (7). To form a single liquid separator apparatus, the inlet orifice (6) is surrounded by an annular flange (9).

In a known refrigerator of this ~ind (G~-PS 20 66 374), the suction connector which is led horizontally through the capsule wall terminates in the plane of thiR wall. A tube comprises a horizontal section coaxial with the suction connsctor, an aIc and a vertlcal section. me inlet or~fice is flared and extends somewhat beyond the vertical ~:ound~proofing wall. The other end of the tube passes through the lower horizont~l sound-proorin~ wall. me horizontal Eection has an oririce at the top con~tituting a direct connection to the sound-proofin~ chamber. In this const~uctlonl gaseou~ refrigerant supplled by uay of the suction connector is fed through tkeinlet orifice, the ftr~t portion of the horizontal tube ~ection and the ori~ice in thc tube wall into the ~uotion chamber, wherea~ droplets of liquid oarrled along into the inlet orifice, i.a. oil or liquid refrigerant, rema$n in the curved tube by reason of their in~tia, impinga on the w~ll of the arc and then clrip into the oil sump through the Yertioal seotion.
Thi~ const~ction has the advantage that a large part of the gaseou~ refrigerant supplied through the suction connector reaches the cuction s3und~proofer directly Bnd i~ therefore supplied to tho rsfri~erant co~p~3ssor at a comparatively low temperature ~hlch9 by ., .., ~
