Definitions

  • the subject invention is directed to a rotary compressor having a one-piece vane mounted in a cylinder having a bore of any one of known cross-sectional shapes specially devised for such one-piece vanes.
  • a hollow rotor is eccentrically located within the cylinder bore and includes two diametrically opposed slots for slid ably receiving the integral vane.
  • a valve plate including outlet valves and a side plate are respcctivaly located on opposite ends ofthc rotor and an oil pump for circulating lubricating oil is also provided in the housing of the compressor.
  • Such a compressor if its rotor is reversely rotated. can be directly used as a vacuum pump as it is.
  • a compressorT in the description ofthe invention and the appended claims comprehends a vacuum pump.
  • a first object of the invention is to provide a rotary compressor having a unitary vane and new and improved lubrication means.
  • the preferred embodiment of the invention is directed to a rotary compressor with a vane of one piece including a cylinder having a bore of any one of known crosssectional shapes specially designed for such a one-piece vane.
  • a hollow rotor is eccentrically located within the cylinder bore so as to be rotated on a fixed axis and is provided with two dimatricaily opposed slots for slidably receiving the vane which extends through the rotor.
  • Valve and slide plates are located on opposite ends of the rotor respectively and an oil pump is provided for circulating oil in the compressor.
  • the rotor is provided with an internal cavity of perfectly circular crosssectional shape.
  • the valve and side plates 7 and 13 are respectively provided with central recesses 41 and 41 of cylindrical shape for receiving the ends of the rotor 29 and oil openings 61 and 61 for supplying the lubricating oil by the oil pump 17 through the oil channels 51 and 53 into oil reservoirs 57 and 57' as described later on with reference to FIG. 5.
  • the oil openings 61 and 61' are preferably located near the fixed inscribing line. but may be located in any position other than said line provided that said oil openings are connected to any one of the oil channels.
  • the outer edge of vane it includes two elongated seal apexes 31 of small mass which extend axially of the cylinder and contact the surface 10 of the cylinder bore.
  • each reservoir 57 is displaced along the peripheral side wall 42 and fed with the lubricating oil through the oil opening 6i provided on the valve plate 7. when said oil opening opens into and communicates with the oil reservoir 57.
  • Corresponding reservoirs 57 are provided on the opposite end of the rotor for communication with opening 61' once during each revolution of the rotor.
  • the invention has substantial advantages over the prior known devices in that the oil reservoirs 57 and 57' are rotated with the rotor so that effective lubrication of all parts is achieved. For example. contacting surfaces between the valve and side plates with the ends ofthe rotor. the vane and said plates and the slots in the rotor and said vane. and the slots for the seal apexes 31. as well as contacting surfaces between the rotor and the cylinder bore on the fixed inscribing line and said bore and the outer ends ofthe vane. are all effectively lubricated.
