This paper describes an application of an electrical contact resistance method to measure contact conditions of sliding parts between a suction-side bush and a blade in a swing compressor, and examined the contact conditions under some operating conditions. In addition, solid contact ratios between the suction-side bush and the blade were calculated from the measured results of contact conditions. The solid contact ratios were compared with those of a vane tip in a rotary compressor. The results indicate that the sliding parts between the suction-side bush and the blade are in the mixed lubrication condition that the solid contact occurs in fluid lubrication. An upper edge side of the suction-side bush is noncontact even though discharge pressure or operating frequency of the compressor increases. Solid contact between a lower edge side of the suction-side bush and the blade increases with an increase of discharge pressure or a decrease of operating frequency of the compressor. The solid contact ratio between the suction side bush and the blade is less than that of the vane tip.
