Title:
REFRIGERANT COMPRESSOR
Document Type and Number:
Japanese Patent JPH1182304
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a reliable refrigerant compressor by optimizing an assembly lubricant used at the time of the assembly of the refrigerant compressor so as to prevent the sliding parts in the refrigerant compressor from being initially worn at the start of the compressor and by suppressing the starting failure of the refrigerant compressor and the occurrence of substances clogging a cooling system. SOLUTION: A refrigerant compressor is structured so that 50 capacity % distillation temperature is 400 deg.C or higher and it uses a synthetic fluid base oil having an ether or carbonate structure in its molecules as an assembly lubricant. In this case, it is better to use the assembly lubricant containing at least one or more organic phosphoric acid compounds of 0.01 to 1.0 wt.% between acid phosphoric acid ester and phosphorous acid ester. Thus the initial wear inside a refrigerant compressor at the start of the compressor can be prevented, and the starting failure and the occurrence of substances clogging a cooling system can be suppressed.
