Compressor

A compressor comprising:

• a casing configured to store lubricating oil in an oil pool disposed in a bottom portion thereof;
• a compression mechanism disposed inside the casing to compress refrigerant;
• a drive shaft disposed inside the casing to drive the compression mechanism;
• a main frame air-tightly joined to an inner peripheral surface of the casing along an entire periphery of the inner peripheral surface, the main frame supporting the drive shaft such that the drive shaft is freely rotatable, and the compression mechanism being disposed on the main frame;
• a motor disposed under the main frame to drive the drive shaft;
• a flow path forming member disposed inside the casing to form an oil flow path at a space adjacent the inner peripheral surface of the casing, the oil flow path being arranged to carry a flow of lubricating oil, which lubricates sliding portions including the compression mechanism and the drive shaft, the oil flow path being disposed above the oil pool, and in any one of a space between the main frame and the motor, a space between the motor and the casing, and a space between the main frame and the casing;
• and
• a temperature measuring mechanism disposed outside the casing to measure a temperature of a section of an outer peripheral surface of the casing so as to measure a temperature of lubricant oil passing through the oil flow path before entering the oil pool,
• the motor including a stator fixed to the inner peripheral surface of the casing,
• the oil flow path having a space contiguous to the inner peripheral surface of the casing,
• the flow path forming member having a section contiguous to the inner peripheral surface of the casing,
• the temperature measuring mechanism measuring a temperature of a temperature measuring region that is a section of the outer peripheral surface of the casing corresponding to a back side of a section of the inner peripheral surface of the casing contiguous to the oil flow path and the flow path forming member, and
• at least a portion of the temperature measuring mechanism being disposed above or below a midpoint of the stator of the motor in an axial direction of the drive shaft.
