Abstract
A compressor includes a casing accommodating a refrigerant passageway, a compression mechanism and a pipe. The compression mechanism is disposed in the interior of the casing to discharge compressed refrigerant into the refrigerant passageway. The pipe extends from inside of the casing to outside of the casing. The pipe includes two ends. One end is a closed end disposed in a predetermined position inside the refrigerant passageway. The other end of the pipe is an opened end disposed outside the casing. The pipe is preferably sized so that a measuring instrument can be inserted into the pipe through the opened end.
Claims20
A compressor for compressing refrigerant, the compressor comprising:
- a casing accommodating a refrigerant passage in an interior thereof;
- a compression mechanism disposed in the interior of the casing to discharge compressed refrigerant into the refrigerant passageway;
- and
- a pipe extending from inside of the casing to outside of the casing,
- the pipe including two ends, with one of the ends being a closed end disposed in a predetermined position inside the refrigerant passage and the other of the ends being an opened end disposed outside of the casing,
- the pipe passing through a space in the interior of the casing and extending from inside of the refrigerant passage to outside of the casing, and
- pressure in the space being different from pressure in the refrigerant passage.
A compressor for compressing refrigerant, the compressor comprising:
- a casing accommodating a refrigerant passage in an interior thereof;
- a compression mechanism disposed in the interior of the casing to discharge compressed refrigerant into the refrigerant passageway;
- a pipe extending from inside of the casing to outside of the casing;
- a motor disposed below the compression mechanism, the motor functioning as a driving source of the compression mechanism;
- and
- a guide plate disposed on an outer periphery of the motor, the guide plate being configured to guide the refrigerant compressed and discharged by the compression mechanism,
- the pipe including two ends, with one of the ends being a closed end disposed in a predetermined position inside the refrigerant passage, and the other of the ends being an opened end disposed outside of the casing, and
- the predetermined position of the closed end of the pipe is disposed between an inner wall of the casing and an outer surface of the guide plate.
A compressor for compressing refrigerant, the compressor comprising:
- a casing accommodating a refrigerant passage in an interior thereof;
- a compression mechanism disposed in the interior of the casing to discharge compressed refrigerant into the refrigerant passageway;
- a pipe extending from inside of the casing to outside of the casing;
- a motor disposed below the compression mechanism, the motor functioning as a driving source of the compression mechanism;
- a guide plate disposed on an outer periphery of the motor, the guide plate being configured to guide the refrigerant compressed and discharged by the compression mechanism;
- and
- a fixed member arranged to rotatably support a shaft connecting the compression mechanism and the motor,
- the pipe including two ends, with one of the ends being a closed end disposed in a predetermined position inside the refrigerant passage, and the other of the ends being an opened end disposed outside of the casing,
- the fixed member including a first recess disposed in a lower end of the outer periphery thereof, the first recess being recessed in a direction away from an inner wall of the casing,
- the guide plate including a second recess disposed in an upper end of an outer periphery thereof, the second recess being recessed in a direction away from the inner wall of the casing, and
- the predetermined position of the closed end of the pipe being disposed inside the first recess and/or the second recess.
A compressor for compressing refrigerant, the compressor comprising:
- a casing accommodating a refrigerant passage in an interior thereof;
- a compression mechanism disposed in the interior of the casing to discharge compressed refrigerant into the refrigerant passageway;
- a pipe extending from inside of the casing to outside of the casing;
- and
- a joint arranged to fix the pipe in an opening firmed in the casing such that the closed end of the pipe is inside of the casing,
- the pipe including two ends, with one of the ends being a closed end disposed in a predetermined position inside the refrigerant passage, and the other of the ends being an opened end disposed outside of the casing, and
- the joint holding the pipe so that a clearance is formed between the pipe and an inner peripheral edge of the opening of the casing.
