Device for cooling of the electric motor of a half hermetic refrigeration compressor

摘要

in the well-known cooling of the electric motor by eingespritztes refrigerant is a separate line with a separate expansionsventil necessary. in the use of oil, which is soluble with the refrigerant hard, there must be an additional oil refrigerant - trenneinrichtung are provided, of the oil in the compressor back must be conducted.the invention is in a simple way the flow of liquid refrigerant to the cooling, as well as the u00f6lru00fcckfu00fchrung of separator for compressor allows. $a after the invention is as the separator oil separator (4) trained and the electric motor (12) de line (10) is u00f6lablau00df (5) of the u00f6labscheiders (4) connected.the invention is in $a refrigeration with cooling of the electric motor by eingespritztes refrigerant in refrigerant, which is soluble with oil difficult to apply.
