  • the sliding-vane compressor of FIG. 1 has rotor 1 provided with vane slots 2 and vanes 3, as well as surrounding stator 4 with inlet opening 5 and outlet channel 6.
  • the rotor shaft is conventionally journalled in stator end sections (not shown) which also serve to enclose the compressor unit.
  • channel grooves 7 are formed on one or both surfaces of rotor body 1, each connecting the inner bottom of a vane slot 2 with its adjacent vane slot 2.
  • the arrows shown on vanes 3 show the direction of movement of vanes 3 during rotation of the compressor, while the arrows in vane slots 2 and channels 7 indicate the corresponding gas flow therein.
  • Suitable positioning and dimensioning of channel grooves 7, as shown, produces a throttling of gas pressure below vanes 3 which balances the pressure influencing vanes 3 in the opposite direction; at the same time, a gas flow occurs which prevents the gas pressure below outwardly moving vanes 3 from falling too low to effectuate full vane operation.
  • FIG. 4 has channel passages 8 formed within rotor body 1, replacing the surface channels of FIGS. 1-3 and serving exactly the same purpose.
  • FIG. 5 has channels 9 so located that the closing off of channels 9 by inwardly moving vanes 3 at a suitable moment of the operation cycle is ensured. During the continued inward movement of vanes 3, the gas enclosed is compressed and thus acquires the counter-pressure necessary for satisfactory vane function.
  • a rotary machine of the sliding vane type comprising:
  • a stator having an inner cylindrical surface
  • a vane mounted in each of said slots to move therein in an outward and inward direction in response to the increasing and decreasing volume of the working chamber to provide yieldingly sliding contact with the inner surface of the stator during the operating cycles of the rotor;
  • narrowed channels interconnecting said slots to provide restricted flow communication for the working medium from the inner closed end of the slots to a location on an adjacent slot spaced outwardly from the inner closed end thereof;
  • said channels being located so as to provide flow communication between two adjacent slots only during a predetermined movement of the vanes therein whereafter the vane by its inward movement interrupts flow through said channels and prevents communication between said two adjacent slots.
  • a rotary machine in which said channels extend from the bottom of one vane slot to an adjacent vane slot at a location having a radius greater than that corresponding to the bottom position of the innermost edge of the vane operating in said adjacent vane slot, and at a radius less than that corresponding to the outermost position of the innermost edge of the same vane.
  • a rotary machine in which said channels are effective to reduce fluid pressure beneath the inwardly moving vanes in response to the increased pressure exerted by the decreasing volume of the working chamber and to increase the pressure he neath the outwardly moving vanes in response to the increasing volume of the working chamber during the operating cycles of the rotor.
