産業上の利用分野
本発明は家庭用エアコン、冷蔵庫等に用いられる冷媒圧
縮機に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a refrigerant compressor used in household air conditioners, refrigerators, and the like.
従来の技術 近年、圧縮機の小型、軽量化の要望は極めて強い。Conventional technology In recent years, there has been an extremely strong demand for smaller and lighter compressors.
以下、図面を参照しながら、従来の回転型圧縮機の一例
について説明する。An example of a conventional rotary compressor will be described below with reference to the drawings.
第３図は、特開昭６１−２５’６２９１号に見られる回
転型圧縮機の断面を示すもので、１は密閉容器で固定子

２は吐出口である。FIG. 3 shows a cross section of a rotary compressor as disclosed in Japanese Patent Application Laid-Open No. 61-25'6291. Reference numeral 1 denotes a closed container in which a motor 4 consisting of a stator 2 and a rotor 3 is housed. 5
is a cylinder that is fixed to the inner diameter of the rotor 3 and forms a compression chamber 6. Reference numeral 7 denotes a cam portion formed on a fixed shaft (not shown) and has an elliptical cross-sectional shape. 8 is vane 1.9
By inserting the vane 8 into the cam portion 7 using a spring, the compression chamber 6 is partitioned into high and low pressure sides. 1o is a suction hole, 11 is a suction port that communicates with the suction hole 1o and the compression chamber 6;
2 is a discharge port.
上記構成において、回転子３０回転に伴い、シリンダ６

て低圧ガスは吸込孔１゜から吸込口１１を経て圧縮室６
に吸引され、圧縮された後、連続して吐出口１２を経て
密閉容器１内に吐出される。In the above configuration, as the rotor rotates 30 times, the cylinder 6
rotates. Since the vane 8 rotates together with the cylinder 6 while being suppressed by the cam portion 7-, the compression chamber 6 is partitioned into a high-pressure side and a low-pressure side, each of which continuously changes in volume. Therefore, the low pressure gas flows from the suction hole 1° through the suction port 11 to the compression chamber 6.
After being sucked in and compressed, it is continuously discharged into the closed container 1 through the discharge port 12.

しかしながら本例によれば、ベーン８はシリンダ５と共
に回転するため、遠心力が生ずる。この遠心力は、ベー
７８をカム部７に押圧するスプリング９の力と反対方向
にかかるため、スプリング９の荷重はペー７８を押圧す

特性を要求さの数倍の値となり、その結果、スプリング
９は巨大なものが必要となる。また、回転圧縮機の起動
時はスプリング９の荷重に打勝つ大きな起動トルクが要
求され、モータ４のコストアップはまぬがれない。However, according to this example, since the vane 8 rotates together with the cylinder 5, centrifugal force is generated. Since this centrifugal force is applied in the opposite direction to the force of the spring 9 that presses the bay 78 against the cam portion 7, the load of the spring 9 is in addition to the load necessary to press the bay 78, and a load corresponding to the centrifugal force. The value is several times higher than the required characteristic, and as a result, the spring 9 needs to be huge. Further, when starting the rotary compressor, a large starting torque is required to overcome the load of the spring 9, which inevitably increases the cost of the motor 4.
本発明は上記問題点に鑑み、コストの安い、より合理的

している。EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, reference numeral 11 denotes a closed container that houses a motor 14 consisting of a stator 121 and a rotor 13. 15 is fixed to the closed container 11 by a shaft. A holder portion 17 has a radial groove portion, is formed concentrically with respect to the shaft 15, and is fixed to the shaft 15. Note that the holder portion may be formed integrally with the shaft 16. A cylinder portion 20 is housed inside the rotor 13 and has a storage chamber 19 formed eccentrically with respect to the center of rotation. A roller 22 is rotatably stored concentrically in the storage chamber 19 of the cylinder portion 20 to form a compression chamber 21 . A vane 25 is slidably fitted into the groove 18. 26 is a spring and base 725
is pressed into the compression chamber 21. 27 is a sand plate that airtightly closes both sides of the roller 22, and holds the rotor 3 rotatably relative to the shirt 16. 3o is a suction pipe fixed to the shaft 15; 31 is a suction hole bored in the shaft 16; 32
is a suction port communicating with the compression chamber 21 and the suction hole 31. 3
4 is a discharge communication hole which communicates the high pressure (111,l) of the compression chamber 21 with the vicinity of the shaft 16 of the groove 18. 36 is a discharge valve formed in the middle of the discharge communication hole 34 in the holder part 17. A discharge muffler 36 is formed on the side plate 27 and communicates with the groove 18 near the shaft 15.
３７は吐出管で密閉容器１１に固定されている。37 is a discharge pipe fixed to the closed container 11.

化を生じる。In the above configuration, as the rotor 13 rotates, the cylinder section 20 rotates, and the storage chamber 19 formed eccentrically with respect to the rotation center rotates eccentrically, so that the compression chamber 21 formed by the roller 22 is rotated in the holder section 17. rotate around. The compression chamber 21 is partitioned into a high-pressure side and a low-pressure side by a vane 26 pressed by a spring 26, and the volume of each side changes continuously.

、摩耗量は少ない。Therefore, the low pressure gas is sucked into the compression chamber 21 from the suction pipe 3o through the suction hole 31 and the suction port 32, and is compressed. The compressed high pressure gas is discharged from the discharge communication hole 34 to the pulp 36
After passing through the groove portion 18 near the shaft 15 and being discharged into the discharge muffler 36 , it is released into the closed container 1 and then discharged through the discharge pipe 37 . Therefore, since the vane 25 does not rotate, no centrifugal force is generated. Furthermore, since the compressed gas passes through the groove 18 and backs up the vane 25, the spring 26 only needs to have the load necessary to press the vane 25 into the compression chamber 21 at the beginning of operation, so it is extremely inexpensive. It can be composed of a coil spring or the like. Furthermore, since the load on the spring 26 is small, the starting torque of the motor 14 can be kept very small, making it possible to use an inexpensive motor. Further, since the roller 22 rotates, the sliding speed of the tip of the vane 25 is low, and the amount of wear is small.
