In a scroll compressor, a thrust ring is mounted between a movable-side flat plate part of a movable scroll and a housing. An upper surface of the thrust ring slides relative to a lower surface of the movable-side flat plate part and supports a thrust load from the movable scroll. A resinous coating is formed on the upper surface of the thrust ring which slides relative to the movable-side flat plate part. The resinous coating is composed primarily of fluorocarbon resin and polyamide-imide resin. The component percentage of the polyamide-imide resin in the primary component of the resinous coating is set, such that it is not less than 65% by mass nor more than 85% by mass.

Fluid machinery

A scroll compressor comprises an operating state detection part ( ) detecting an operating state, a variable-speed motor ( ), a control part ( ) and an unloading mechanism ( ) serving as capacity control means. The control part ( ) controls operation of the unloading mechanism ( ) and the rotational frequency of the motor ( ) in response to the operating state detected by the operating state detection part ( ). An air conditioner comprises the aforementioned scroll compressor, a condenser ( ), an expansion valve ( ) and an evaporator ( ).

Scroll compressor and air conditioner

A plurality of compression chambers are formed between first and second spiral bodies,and,, and refrigerant discharge timing advancing means is provided for advancing the timing at which refrigerant is discharged from a first compression chamber,which is one of a pair of compression chambers located nearest to the center, relative to the refrigerant discharge timing of the second compression chamber,. The refrigerant discharge timing advancing means includes an extension,of the first spiral body,and an opening advancing portion,of a discharge port
