  • Compressor having external temperature sensor and method of manufacturing compressor
    Patent number: 11261866
    Abstract: A compressor includes a casing having a cylindrical portion, a compression mechanism fixed to an inner peripheral surface of the cylindrical portion, an external portion, a weld nut, and a bolt. The external portion includes a temperature reaction portion that reacts to a temperature change of the cylindrical portion. The external portion is mounted on an outer peripheral surface of the cylindrical portion. The weld nut is welded to the outer peripheral surface of the cylindrical portion to mount the external portion on the outer peripheral surface of the cylindrical portion. The bolt fixes the external portion to the weld nut.

  • Rotary compressor having a muffler with a discharge region to discharge compressed gas toward an outer surface of the crankshaft
    Patent number: 8282364
    Abstract: A rotary compressor includes a rotation compression element, a discharge port and a muffler. The rotation compression element is configured to compress gas as a result of rotation of a crankshaft about a rotation axis. The discharge port is configured to discharge the gas compressed by the rotation compression element. The muffler is arranged to cover the discharge port and surround the crankshaft. The muffler has a muffler crankshaft hole through which the crankshaft passes, and a muffler discharge region configured to discharge the compressed gas discharged from the discharge port toward an outer surface of the crankshaft.
