Definitions

  • FIG. 3 is a sectional view thereof taken along one A-A of FIG. 2 and viewed in the direction of the arrows, wherein the section is taken through the suction port;
  • FIG. 5 is a sectional view thereof taken through the discharge ports
  • FIG. 6 is a transverse sectional view of the compressor taken through the cylinder
  • FIG. 8 is a perspective view of the main bearing
  • FIG. 1 illustrates the rotary compressor 10 forming one embodiment of the present invention.
  • Compressor 10 includes an outer hermetic housing 12 including center portion 14 to which upper and lower caps 16 and 18 are connected, such as by welding.
  • a conventional suction accumulator 20 having inlet 22 and outlet suction line 24 is connected to the center portion 14 of compressor 10 by means of mounting strap 26 .
  • Compressed refrigerant is discharged from high pressure housing 12 through discharge line 28 .
  • Compressor 10 may be a component of a heating and/or cooling circuit and functions to compress the working fluid, such as a refrigerant, which may be a hydrofluorocarbon, chlorofluorocarbon, hydrochlorofluorocarbon, or carbon dioxide refrigerant, for example.
  • An elongate cam 46 which is preferably elliptical, is preferably integrally connected with crankshaft 14 , although alternatively it may be a separate element connected by any suitable means.
  • Shaft 64 is rotationally secured to rotor 28 and, as shown in FIG. 6 , cam 46 is in sealing engagement with the bore 50 of cylinder 34 .
  • Passages 94 and suction pressure channel 70 may possibly be used in conjunction with one another or, alternatively, employed separately.
  • suction pressure channel 74 is present and passages 94 are absent.
  • passages 94 are present and suction pressure channel 74 is absent.
  • elongate cam 46 also eliminates the need for an outboard journal bearing.
  • the outboard journal extends around the oil paddle and through an opening in the outboard bearing.
  • the interaction of the journal with the portion of the outboard bearing that defines the opening prevents off-centered movement of the crankshaft and eccentric during rotation of the crankshaft.
  • the interaction of opposing pressure forces on exterior surface 66 of cam 46 substantially eliminates the need for an outboard journal on crankshaft 48 .
  • the need to create a correspondingly highly machined journal and outboard bearing 40 is also eliminated.
  • the cost of manufacturing a rotary compressor in accordance with this embodiment of the invention is substantially reduced.
