と同心状に設けられている。 An example of a conventional compressor of this type will be explained with reference to a sectional view shown in FIG. The one shown in Fig. 1 is commonly called a rolling piston type, and in Fig. 1, 1 is a cylinder, 2 is a rolling piston, 3 is a crankshaft, 4 is a vane, 5 is a spring, and 6 is a vane groove. , 7 is a spring holder,
8 is a suction chamber, 9 is a compression chamber, 10 is a suction port, 11 is a discharge port, 12 is a discharge valve, 13 is a suction pipe, 14 is a suction muffler, and 15 is a shell. Note that 0 is the center of rotation when the crankshaft 3 is connected to, for example, a motor (not shown), and 0' is the center of the eccentric part of the crank.Although not clearly shown in FIG.
The bearing part fitted with cylinder 1 is centered at 0.
It is arranged concentrically with.

室９の容積は零となる。 A conventional positive displacement compressor is configured, for example, as described above, and refrigerant from outside air or a device such as a refrigeration cycle is sucked into the suction chamber 8 through the suction muffler 14, the suction pipe 13, and the suction port 10. As the rolling piston 2 centered at the eccentric portion between 0 and 0' rotates, for example, in the direction of arrow A in FIG. Continue to increase. On the other hand, as the rolling piston 2 rotates as described above, the volume of the compression chamber 9 decreases, so the pressure of the gas in the compression chamber 9 increases, pushing down the discharge valve 12 and flowing out. In FIG. 1, when the rolling piston 2 presses the vane 4 to the right without the protruding portion 4a, that is, when the vane 4 is completely accommodated in the vane groove 6, the suction stroke and compression At the same time as the stroke ends, the next suction stroke and compression stroke begin. That is, in this state, the volume of the suction chamber 8 becomes the maximum value obtained by subtracting the volume of a cylinder having the same external shape as the rolling piston 2 from the space formed by the inner wall of the cylinder 1, and the volume of the compression chamber 9 becomes zero.

していた。 By the way, in the positive displacement compressor configured as described above, the pressure difference between the compression chamber 9 and the suction chamber 8 is
0', it not only generates a rotational moment around 0 to 0', but also causes the rolling piston 2
Since the same amount of pressure is applied to the crankshaft 3 as the pressure acting on the eccentric part of the crankshaft 3 connected to the rolling piston 2, a load is generated between the rolling piston 2 and the eccentric part of the crankshaft 3. Further, the same load is generated between the crankshaft 3 and a bearing portion (not shown) on which the crankshaft 3 is supported, and the crankshaft 3 has the drawback of sometimes damaging the bearing.
また、０を中心とし、０〜0′を腕とするクラン
ク軸３の偏心部分にローリングピストン２の質量

バランスウエイト等を取付けてバランシングを行
なわなければならないという欠点を有していた。 In addition, the mass of the rolling piston 2 is unevenly distributed on the eccentric part of the crankshaft 3 with 0 as the center and arms as 0 to 0', so in order to achieve smooth rotation, a balance weight or the like must be attached to perform balancing. It had the disadvantage that it had to be done.

とができない欠点があつた。 Further, since only one rotation and one compression can be performed, the fluctuation frequency of the gas compression torque serving as the vibration source matches the rotational speed of the driving source, such as a motor. Therefore, when trying to isolate vibration by moving the frequency of the gas compression torque fluctuation away from the natural frequency of the vibration isolation system, that is, the vibration isolation spring, etc., it is necessary to set the natural frequency of the vibration isolation spring sufficiently far from the frequency of the gas compression torque fluctuation. had a drawback that could not be avoided.

式の容積形圧縮機を得ることを目的とする。 This invention was made to eliminate the above-mentioned drawbacks of the conventional technology.In principle, no bearing load occurs, there is no need for mechanical balancing at all, and the frequency of the gas compression torque is reduced during design. The purpose of the present invention is to provide a new type of positive displacement compressor that can be arbitrarily selected, reduce vibrations, and easily realize compactness and weight reduction.

The top portion of the smooth peak 28 of the wavy portion 29 corresponds to the line segment 20.

とは容易に推定できるであろう。 Therefore, the space V 1 in FIG. 2 corresponds to the suction chamber, the space V 2 corresponds to the compression chamber, and the plane 25 corresponds to the vane, and the three-dimensional object is rotated by an appropriate driving source, and the three-dimensional object is It can be easily assumed that a positive displacement compressor can be constructed by constructing a cylinder housing that covers an object and installing an inlet, a discharge port, etc.

Although there are two spaces corresponding to the compression chambers, for example V 2 , it is immediately understood that the number of peaks and valleys in the wavy surfaces 21 and 22 may be one or more than three. In that case, plane 25
The same number of vanes as the number of peaks or valleys are required.

This rotating body 30 has a similar shape to that shown in FIG. In other words, the rotary body 30 is nothing but an object housed in the cylinder housing. In other words, the corrugated portion 29 is integrally formed in the body to be stored, which is the rotating body 30. Reference numeral 31 denotes a cylinder housing consisting of a cap-shaped cylindrical portion with one end open and a closing plate that closes the opening of the cylindrical portion, and its inner peripheral surface is in sliding contact with the cylindrical surface 24 of the rotating body 30, and is located at the upper end thereof. The tops of the peaks 28 of the corrugated portions 29 of the rotating body 30 are in sliding contact with the inner surface of the closing plate, and these tops constitute a sealing portion 32 .

縮行程に入り、圧縮室９となる。 In the example shown in FIGS. 3 to 5, a wavy portion 29 having two peaks 28 similar to the case shown in FIG.
The rotating body 30 equipped with
8, the compression chamber 9 is formed between the top of the peak 28 of the corrugated portion 29, that is, the seal portion 32, and the vane 4, which is pressed against the corrugated portion 29 by the spring 5. As the rotating body 30 rotates, its volume decreases, the pressure rises, and the gas contained therein pushes up the discharge valve 12 and flows into the discharge port 36 from the discharge port 11. On the other hand, the gas sucked into the suction chamber 8 from the suction port 35 via the suction port 10 increases its volume, and
When 2 coincides with vane 4, inhalation is completed. On the other hand, at this time, the volume of the compression chamber 9 becomes zero, and compression is completed. After completing the suction stroke, the suction chamber 8 immediately enters the compression stroke and becomes the compression chamber 9.
この例のように、圧縮室９が２つある場合、あ

生じないことが理解される。 As in this example, when there are two compression chambers 9, or even when there are two or more, the corrugated portions 29 of the rotating body 30 are arranged at equal pitches, so that the pressure in the compression chambers 9 is maintained with respect to the rotating shaft 33. It is understood that since the pressure in the suction chamber 8 also cancels out with respect to the rotating shaft 33, no load is generated between the rotating shaft 33 and the bearing 34 provided in the cylinder housing 31.
また、回転体３０は等ピツチの波状部２９およ
び回転軸３３を有しているので、回転軸３３のま
わりには、静的にも動的にもバランスがとれてい
ることは明らかで、バランスリングはモータ３８
で駆動する場合にも全く不要となることが分か
る。 Furthermore, since the rotating body 30 has the equally pitched wavy portions 29 and the rotating shaft 33, it is clear that the rotating shaft 33 is statically and dynamically balanced. The ring is motor 38
It can be seen that it is completely unnecessary even when driven by
ところで、回転体３０は、例えば第６図のよう
に、２つ以上の等ピツチの波状部２９をもつもの
でもよいので、一回転中に吸入圧縮吐出の行程を
多数回に選ぶことが可能となり、定速運転の場合
の気体圧縮トルク脈動の周波数を任意に選択でき
ることも明らかである。 By the way, the rotary body 30 may have two or more equally spaced undulating portions 29, as shown in FIG. 6, for example, so that it is possible to select a number of suction, compression and discharge strokes during one rotation. It is also clear that the frequency of the gas compression torque pulsations in the case of constant speed operation can be arbitrarily selected.
ここで、第２図、第６図に示す如く、等ピツチ

体本体を小さくでき、軽量化が可能となる。この
ように等ピツチの波状部２９の山２８の数、すな
わちシール部３２の数を適切範囲で増加させるこ
とによつて、小形計量化が可能となる。 Here, as shown in FIGS. 2 and 6, a case will be considered in which the ridges 28 of the wavy portions 29 of equal pitch, that is, the number of seal portions 32 are different. For example, if the corrugated portion 29 has two peaks 28 as shown in FIG. 2, one suction compression is performed in 1/2 rotation, and two suction compressions are performed in one rotation. Further, when the corrugated portion 29 has three or more peaks 28 as shown in FIG. 6, suction compression is performed once in 1/3 rotation, and suction compression is performed three times in one rotation. Therefore, for example, when driven by a motor 38 with the same rotational speed and inhaling and discharging the same volume of gas, the rotating body 30 having the corrugated portion 29 having three peaks 28 shown in FIG. 6 rotates faster. The main body can be made smaller and lighter. In this way, by increasing the number of ridges 28 of the equally pitched wavy portion 29, that is, the number of seal portions 32 within an appropriate range, it becomes possible to reduce the size and weight.
尚、図示した実施例において、必要に応じて潤
滑機構が付加できるのは言う迄もない。 It goes without saying that a lubrication mechanism can be added to the illustrated embodiment if necessary.
実施例では回転体３０は波状部２９を片側に有
するもののみについて説明したが、回転体３０の
軸方向に沿つてその両側に波状部２９を形成して
もよい。この場合には、回転体３０に加わる軸方
向の圧力が相殺され、結果として回転体３０に加
わる軸方向の圧力が極めて小さくなる。 In the embodiment, the rotating body 30 has only the corrugated portion 29 on one side, but the corrugated portion 29 may be formed on both sides of the rotating body 30 along the axial direction. In this case, the axial pressure applied to the rotating body 30 is canceled out, and as a result, the axial pressure applied to the rotating body 30 becomes extremely small.
この発明は以上説明したとおり、同一パターン

で、低振動かつ軽量化が図れるという極めて優れ
た容積形圧縮機を可能にする効果がある。 As explained above, this invention is configured so that the storage object having the same pattern of wavy portions is rotated to change the volume of the space formed by the vane, the wavy portion, and the storage object, so that the bearing load is basically reduced. This has the effect of making it possible to create an extremely superior positive displacement compressor, which does not require a mechanical balance ring or the like, and is low in vibration and lightweight.
