線１機に関するものである。DETAILED DESCRIPTION OF THE INVENTION 2. Field of Industrial Application The present invention relates to a refrigerant pressure line 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 compressors to be smaller and lighter.
以下、図面を参照しながら、従来のロータリ圧縮機の一
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、４１１開昭６１−２５５２９１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及び回転子３からなるモータ４が収納されている。FIG. 3 shows a cross section of a rotary compressor seen in No. 411, No. 61-255291, in which reference numeral 1 denotes a closed container in which a motor 4 consisting of a stator 2 and a rotor 3 is housed.

、１２は１１出［二１である。A cylinder 5 is fixed to the inner diameter of the rotor 3 and forms a compression chamber 6. The end is a cam portion formed on a fixed shaft (not shown) and has an elliptical cross-sectional shape. 8 is vane, 9
By causing the vane 8 to be crushed by the cam portion 7 using a spring, the compression chamber 6 is partitioned into a low pressure side. 10 is a suction hole, 11 is a suction port communicating with the suction hole 10 and the compression chamber 6, and 12 is an 11 outlet [21].

密閉容器１内に吐出される。In the above configuration, as the rotor 3 rotates, the cylinder 5
rotates. Since the vane 8 rotates together with the cylinder 5 while being pressed by the cam member, the compression chambers are cut into a high-pressure side and a low-pressure side, causing a continuous change in volume. Therefore, the low pressure gas flows from the suction hole 10 through the suction port 11 into the compression chamber 6.
After being sucked in and compressed, it is continuously discharged into the closed container 1 through the discharge port 12.

、モータ４のコストアップはまぬがれない。Problems to be Solved by the Invention However, according to this example, since the bay 78 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 vane 8 against the cam portion 7, the load of the spring 9 is in addition to the load necessary to press the vane 8, and a load corresponding to the centrifugal force. characteristics are required. The centrifugal force has a value several times greater than the load required to suppress the vanes 8, especially when the rotational speed becomes high due to an inverter, etc., and as a result, a large spring is required. Furthermore, 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.

In FIGS. 1 and 2, reference numeral 11 denotes a closed container that houses a motor 14 consisting of a stator 12 and a rotor 13. 15 is fixed to the closed container 11 by a shaft. The holder part has a radial groove part, 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 15. Reference numeral 2Q denotes a cylinder portion, which 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 2o, forming a compression chamber 21'. The rollers 24 are υ bearings, and the storage chamber 1
9 and the roller 22. Is 25 a vane? A slide 1 is mounted in the l"It' portion 18. 26 is a stub link that presses the vane 25 to the inside of the shrinking chamber 21.

It is fixed at 5. Reference numeral 31 designates nine suction holes formed in the shaft 15, and reference numeral 32 represents a suction port that communicates with the compression chamber 21 and the suction hole 31. 35 is a discharge valve formed inside the holder part 17.

容積変化を生じる。In the Kamidate configuration, as the rotor 13 rotates, the cylinder part 20 rotates, and the storage chamber 19 formed eccentrically with respect to the center of rotation rotates eccentrically, so that the compression chamber 21 formed by the roller 22 rotates as the holder part 1 ends. It spins around and rotates. FL
The vane 25 is pressed by the spring 26 of the contraction chamber 211d, and is applied to the high pressure side and the low pressure side, causing a continuous change in volume.

The compressed high-pressure gas is discharged into a discharge muffler 36 through a discharge valve 35, released into the closed container 1, and then discharged through a discharge pipe 37.

耗量は少ない。Therefore, since the vane 25 does not rotate, no centrifugal force is generated, and the spring 26 moves the vane 25 into the compression chamber.
1. Since it is sufficient to have the load necessary to press the inner side, it can be constructed using an extremely inexpensive coil splinter 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 by the rolling bearing 24 regardless of the rotation of the storage chamber 19, the sliding speed of the tip of the vane 25 is small, and the amount of wear is small.
