Abstract
The invention relates to refrigeration apparatus of the type having a casing which contains an electric motor and reciprocating compressor means. This type of apparatus is subject to creating undesirable vibrations and noises, the reduction of which is the object of the invention. This is done by adding additional mass to the casing which is equal to fifty per cent or more of the mass of the casing. The correspondingly greater mass inertia has the effect of causing the casing to absorb vibrations emanating from the interior of the casing to a lesser extent than before.
