  • the lubrication oil in the high pressure chamber 15 is fed by pressure difference to the compression chamber X along a compression-chamber-side outer peripheral portion of the support body 4 and a compression-chamber-side wall portion of the blade 21.
  • the outer peripheral portion, upper and lower end faces and receiving hole 41 of the support body 4 can be supplied with oil, and therefore the outer peripheral portion and upper and lower end faces of the support body 4 and further the receiving groove 41 on which the blade 21 slides can be effectively lubricated.
  • Fig. 5 shows the overall configuration of a horizontal rotary compressor having a high pressure dome according to a third embodiment.
  • a motor 102 composed of a stator 121 and a rotor 122 is arranged on one lateral side of the horizontal casing, and a compression element 104 driven by a drive shaft 103 extending from the rotor 122 is arranged on the other side within the casing 101.
  • the compression element 104 has a cylinder 105 having a cylinder chamber 151 therein, and a front head 106 and a rear head 107 are arranged on both sides of the cylinder 105 in the axial direction.
  • a tube-shaped roller 108 fitted on the eccentric portion 131 of the drive shaft 103 is installed, and on the roller 108 is integrally formed a blade 109 partitioning the cylinder chamber 151 into a compression chamber X communicating to a discharge port 152 provided on the cylinder 105 and a suction chamber Y communicating to a suction port 153 so that the blade 109 protrudes from the outer periphery of the roller 108 outward in the radial direction, and the blade 109 is swingably supported by a support body 110 rotatably provided in the cylinder 105.
  • the roller 108 revolves within the cylinder chamber 151, and gaseous fluid introduced through a suction tube 101a connected to the suction port 153 is sucked into the suction chamber Y and then compressed in the compression chamber X, and the compressed gas is then discharged from the discharge port 152, via a muffler provided on the outer side of the front head 106, to an internal space of the casing 101 and then to the outside through a discharge tube 101b opened to the motor 102 within the casing 101.
  • the blade 109 is disposed slantwise in an upper portion of the cylinder 105 apart from the oil sump O of the casing 101.
  • an oil chamber 154 being a closed space is formed on a rear side of the blade 109 for supplying oil to the blade 109, and a high-pressure oil supplied to the compression chamber X is input, by the pressure difference from a pressure of the compression chamber X, into the oil chamber 154 via a clearance defined between the blade 109 and the support body 110.
  • the oil input into the oil chamber 154 is then output therefrom into the suction chamber Y via a clearance defined between the blade 109 and the support body 110. Contacting portions of the blade 109 is lubricated through the input and output of the oil.
  • the blade 109 is supplied with oil from the oil chamber 154 disposed on the rear side of the blade, as described above, it is not necessary to make the blade 109 confront the oil sump O. This makes it possible to set the blade in any desired position in the cylinder 105. Consequently, the blade 109 can be arranged in an upper portion of the cylinder 105 apart from the oil sump O. This makes it possible to provide the discharge port 152 and suction port 153, which must be provided in the vicinity of the blade 109, in positions apart from the oil sump O. Therefore, the suction gas entering from the suction port 153 is prevented from being overheated by the high temperature oil in the oil sump O, whereby the reduction in volume efficiency is suppressed and the power is increased.
  • the arrangement of the blade 109 in the upper position in the cylinder 105 allows the suction port 153 to be provided in the cylinder high above the oil sump O, the work for connecting the suction tube 101a to the suction port 153 is readily done from one lateral side of the casing 101. Thus, workability can be increased. Furthermore, because there is no necessity to secure a space for the suction tube 101a on a lower side of the casing 101, the height of the casing 101 can be reduced when assembled.
  • an oil groove 111 radially extending therethrough, one longitudinal end of which is open to the inner peripheral surface of the roller 108 and the other end of which is open to the oil chamber 154 provided on the rear side of the blade 109.
  • this high pressure oil maintains the oil chamber 154 in a high pressure state all the time, the oil in the oil chamber 154 can be fed, by pressure difference, to the suction chamber Y which is held lower in pressure relative to the oil chamber 154, via the clearance between the support body 110 supported within the cylinder 105 and the blade 109.
  • the lubrication oil in the oil chamber 154 is fed, by pressure difference, to the compression chamber X as well via the clearance between the support body 110 and the blade 109.
  • the blade 109 can be lubricated more securely and therefore the lubrication performance for the blade 109 is enhanced.
  • the swing type rotary compressor according to the present invention is primarily employed in the refrigeration apparatus.
