特許第5756842号公報Japanese Patent No. 5756842

特許文献１の背圧室は閉込み開始後の前記両圧縮室へ至る吸込領域とを連通し、両圧縮室内の圧力差により背圧室の圧力が変動する。背圧により旋回スクロールは固定スクロールへ押し付けられているため、旋回スクロールが揺動し体積効率および圧縮機効率の低下を招く恐れがある。 The back pressure chamber of Patent Document 1 communicates with the suction regions leading to the two compression chambers after the start of closing, and the pressure in the back pressure chamber fluctuates due to the pressure difference between the two compression chambers. Since the swivel scroll is pressed against the fixed scroll by the back pressure, the swivel scroll may swing, resulting in a decrease in volumetric efficiency and compressor efficiency.

体積効率および圧縮機効率の低下を防ぐスクロール圧縮機を提供することを目的とする。 It is an object of the present invention to provide a scroll compressor that prevents a decrease in volumetric efficiency and compressor efficiency.

上記事情に鑑みた本発明は、旋回ラップを有する旋回スクロールと、固定ラップを有する固定スクロールと、前記旋回ラップの内線と前記固定ラップの外線とで形成される第１の圧縮室と、前記旋回ラップの外線と前記固定ラップの内線とで形成される第２の圧縮室と、を備え、圧縮給油路に接続された孔は、前記第１の圧縮室へ連通する状態と、前記旋回スラップにより塞がれる状態と、を有することを特徴としたスクロール圧縮機。 In view of the above circumstances, the present invention has a swivel scroll having a swivel lap, a fixed scroll having a fixed lap, a first compression chamber formed by an inner line of the swivel lap and an outer line of the fixed lap, and the swivel. A second compression chamber formed by an outer line of the lap and an inner line of the fixed wrap is provided, and the hole connected to the compression lubrication passage is in a state of communicating with the first compression chamber and by the swirling slap. A scroll compressor characterized by having a closed state.

［スクロール圧縮機の概要］
スクロール圧縮機１は、作動流体を圧縮する固定スクロール２と旋回スクロール３、旋回スクロール３を回転させるクランク軸６、クランク軸６の主軸受２４を有するフレーム４、クランク軸６に回転力を付与するモータ７、これらを内包するケーシング８、を備えている。 [Overview of scroll compressor]
The scroll compressor 1 applies a rotational force to the fixed scroll 2 and the swivel scroll 3 for compressing the working fluid, the crankshaft 6 for rotating the swivel scroll 3, the frame 4 having the main bearing 24 of the crankshaft 6, and the crankshaft 6. A motor 7 and a casing 8 containing these are provided.

スクロール圧縮機１は、一端がスクロール圧縮機の外部に、他端が吸込み口２ｓに繋がる吸込パイプ５０を有する。吸込パイプ５０の一端から作動流体がスクロール圧縮機１内部に取り込まれると、他端の吸込み口２ｓから、固定スクロール２と旋回スクロール３とによって形成される吸込室９０に作動流体が導入される。吸込室９０に導入された作動流体は、スクロールにより圧縮されて、固定スクロール２の上部に位置する固定背面室１２０に吐出される。吐出された圧縮流体はケーシング８下方に流れて、ケーシング８下方に貯留された貯油部１２５の油を昇圧する。 The scroll compressor 1 has a suction pipe 50 having one end connected to the outside of the scroll compressor and the other end connected to the suction port 2s. When the working fluid is taken into the scroll compressor 1 from one end of the suction pipe 50, the working fluid is introduced into the suction chamber 90 formed by the fixed scroll 2 and the swivel scroll 3 from the suction port 2s at the other end. The working fluid introduced into the suction chamber 90 is compressed by the scroll and discharged to the fixed back chamber 120 located above the fixed scroll 2. The discharged compressed fluid flows below the casing 8 and boosts the oil in the oil storage unit 125 stored under the casing 8.

クランク軸６には、貯油部１２５に浸された給油パイプ６ｘの下端が配されており、旋回スクロール３とフレーム４との間に形成された背圧室１１０にまで貯油部１２５の油を汲み上げることで、背圧室１１０は油溜部として機能できる。背圧室１１０へ流入する油の圧力は、上述の経緯により吐出圧Pdとなるため、その油の流入によって背圧室１１０が昇圧する。背圧室１１０が昇圧し、これにより旋回スクロール３は固定スクロール２に押し付けられる。また、クランク軸６の上端に位置する偏心部６ａは、旋回スクロール３下面の旋回軸受２３に挿入される。旋回スクロール３は、クランク軸６の回転に伴い旋回運動して固定スクロール２に対して相対運動する。 The lower end of the oil supply pipe 6x immersed in the oil storage unit 125 is arranged on the crankshaft 6, and the oil of the oil storage unit 125 is pumped up to the back pressure chamber 110 formed between the swivel scroll 3 and the frame 4. As a result, the back pressure chamber 110 can function as an oil reservoir. Since the pressure of the oil flowing into the back pressure chamber 110 becomes the discharge pressure Pd due to the above-mentioned process, the back pressure chamber 110 is boosted by the inflow of the oil. The back pressure chamber 110 boosts the pressure so that the swivel scroll 3 is pressed against the fixed scroll 2. Further, the eccentric portion 6a located at the upper end of the crankshaft 6 is inserted into the swivel bearing 23 on the lower surface of the swivel scroll 3. The swivel scroll 3 swivels as the crankshaft 6 rotates, and moves relative to the fixed scroll 2.

［圧縮］
図２は実施例１の旋回スクロール３を固定スクロール２に配した状態の正面図である。旋回スクロール３は、平板状の旋回鏡板３ａと、旋回鏡板３ａの固定スクロール２側の面としての旋回面３ａ１と、そこから立設する旋回ラップ３ｂと、を有する。旋回スクロール３の上面側には固定スクロール２が配される。 [compression]
FIG. 2 is a front view showing a state in which the swivel scroll 3 of the first embodiment is arranged on the fixed scroll 2. The swivel scroll 3 has a flat swivel end plate 3a, a swivel surface 3a1 as a surface of the swivel end plate 3a on the fixed scroll 2 side, and a swivel lap 3b erected from the swivel surface 3a1. A fixed scroll 2 is arranged on the upper surface side of the swivel scroll 3.

固定スクロール２は、平板状の固定鏡板２ａと、固定鏡板２ａの下面側に位置し旋回ラップ３ｂの巻方向とは逆向きの渦巻き状に立設する固定ラップ２ｂと、圧縮流体を吐出する吐出穴２ｄと、固定ラップ２ｂより外周側に位置して円状の固定台板面２ｕを有する。固定ラップ２ｂの外周寄りには吸込パイプ５０の吸込み口２ｓが、また、中央付近には吐出孔２ｄが形成されている。これら固定ラップ２ｂおよび旋回ラップ３ｂを噛合わせることで、圧縮室１００が形成される。圧縮室１００は、旋回ラップ３ｂの内周面と固定ラップ２ｂの外周面との間としての第１の圧縮室１００aと、旋回ラップ３ｂの外周面と固定ラップ２ｂの内周面との間としての第２の圧縮室１００bとが形成される。 The fixed scroll 2 includes a flat plate-shaped fixed end plate 2a, a fixed wrap 2b located on the lower surface side of the fixed end plate 2a and erected in a spiral shape opposite to the winding direction of the swirl wrap 3b, and a discharge for discharging compressed fluid. It has a hole 2d and a circular fixed base plate surface 2u located on the outer peripheral side of the fixed wrap 2b. A suction port 2s of the suction pipe 50 is formed near the outer periphery of the fixed wrap 2b, and a discharge hole 2d is formed near the center. The compression chamber 100 is formed by engaging the fixed wrap 2b and the swirling wrap 3b. The compression chamber 100 is formed between the first compression chamber 100a between the inner peripheral surface of the swirl wrap 3b and the outer peripheral surface of the fixed wrap 2b, and the outer peripheral surface of the swirl wrap 3b and the inner peripheral surface of the fixed wrap 2b. A second compression chamber 100b is formed.

旋回スクロール３が旋回すると、旋回スクロール３と噛合う固定スクロール２の間の外辺部に吸込室９０が形成され、吸込室９０に流入した作動流体は、閉込み開始によって圧縮室１００へ移行していき、容積が縮小する。これによって圧縮室１００内部の作動流体は圧縮され、固定ラップ２ｂ，旋回ラップ３ｂ中央側に位置する吐出穴２ｄから固定背面室１２０へ流出する。 When the swivel scroll 3 swivels, a suction chamber 90 is formed on the outer side between the fixed scroll 2 that meshes with the swivel scroll 3, and the working fluid that has flowed into the suction chamber 90 moves to the compression chamber 100 when the confinement starts. The volume shrinks. As a result, the working fluid inside the compression chamber 100 is compressed and flows out to the fixed back chamber 120 from the discharge hole 2d located on the center side of the fixed wrap 2b and the swirling wrap 3b.

固定背面室１２０へ流出した作動流体の圧力を吐出圧Pdとする。固定背面室１２０へ流出した作動流体は、ケーシング８下方である貯油部１２５側の空間に流れて貯油部１２５に吐出圧Pdを加えるとともに吐出パイプ５５から外部へ吐出される。貯油部１２５に加えられた圧力により、油はクランク軸内に設けられた給油穴６ｂを上昇していく。この油によって昇圧されるため、背圧室１１０の圧力（背圧という。）は、吸込口２ｓや吸込部９５の圧力である吸込圧Psより高い。 The pressure of the working fluid flowing out to the fixed back chamber 120 is defined as the discharge pressure Pd. The working fluid flowing out to the fixed back chamber 120 flows into the space on the oil storage unit 125 side below the casing 8, applies a discharge pressure Pd to the oil storage unit 125, and is discharged from the discharge pipe 55 to the outside. Due to the pressure applied to the oil storage unit 125, the oil rises through the oil supply hole 6b provided in the crankshaft. Since the pressure is increased by this oil, the pressure in the back pressure chamber 110 (referred to as back pressure) is higher than the suction pressure Ps, which is the pressure of the suction port 2s and the suction portion 95.

なお、吐出穴２ｄの外周側には複数のバイパス穴２ｅが形成され、各々にバイパス弁２２が設けられている。バイパス弁２２は、圧縮室１００の圧力がケーシング８の内部の圧力よりも等しくなるかわずかに高くなると開弁するようになっている。
過圧縮条件では、圧縮室１００の内部の圧力が吐出圧Pdとなるため、図1に示すバイパス弁２２が開いて、バイパス穴２ｅを介して、圧縮室１００の内部の作動流体を固定背面室１２０へ流出させる。 A plurality of bypass holes 2e are formed on the outer peripheral side of the discharge hole 2d, and a bypass valve 22 is provided in each of the bypass holes 2e. The bypass valve 22 opens when the pressure in the compression chamber 100 becomes equal to or slightly higher than the pressure inside the casing 8.
Under the overcompression condition, the pressure inside the compression chamber 100 becomes the discharge pressure Pd. Therefore, the bypass valve 22 shown in FIG. 1 is opened to fix the working fluid inside the compression chamber 100 through the bypass hole 2e. Let it flow out to 120.

［圧縮給油路６０］
図３は図１のＳ部で囲む背圧弁付近の部分拡大縦断面図である。固定スクロール２には、背圧弁２６、圧縮給油路６０が設けられている。
上述のように、旋回スクロール３とフレーム４とで囲まれた空間としての背圧室１１０には油が貯留されており、背圧室１１０の油は、背圧弁２６が開放すると、圧縮給油路６０を通じて第１の圧縮室１００aに流れる。 [Compressed refueling path 60]
FIG. 3 is a partially enlarged vertical cross-sectional view of the vicinity of the back pressure valve surrounded by the S portion of FIG. The fixed scroll 2 is provided with a back pressure valve 26 and a compression oil supply passage 60.
As described above, oil is stored in the back pressure chamber 110 as a space surrounded by the swivel scroll 3 and the frame 4, and the oil in the back pressure chamber 110 is compressed when the back pressure valve 26 is opened. It flows through the 60 to the first compression chamber 100a.

背圧弁２６は、弁座として固定スクロール２に圧入された背圧弁ピース２６ａと、弁体と、弁体を移動させる弾性体とを有する。
圧縮給油路６０は、背圧室１１０に設けられた背圧室側開口部６０ａと、第１の圧縮室１００aに設けられた圧縮室側開口部６０ｂとを繋いでいる。圧縮給油路６０には背圧弁２６が設けられており、背圧室側開口部６０ａは、背圧弁ピース２６ａを貫通する穴である。 The back pressure valve 26 has a back pressure valve piece 26a press-fitted into the fixed scroll 2 as a valve seat, a valve body, and an elastic body that moves the valve body.
The compression oil supply passage 60 connects the back pressure chamber side opening 60a provided in the back pressure chamber 110 and the compression chamber side opening 60b provided in the first compression chamber 100a. A back pressure valve 26 is provided in the compression oil supply passage 60, and the back pressure chamber side opening 60a is a hole penetrating the back pressure valve piece 26a.

背圧弁２６は、背圧室１１０の圧力（背圧）が所定値Ｐｍ以上になると開弁するようになっており、背圧が吐出圧Pdより低く維持される。これにより、背圧は、吸込圧Ｐｓ超吐出圧Ｐｄ未満である中間圧Pm近辺になる。第１の圧縮室１００aによる圧縮が開始されると、途中で背圧弁２６が開放し、背圧室１１０の油が通過することになる。 The back pressure valve 26 is adapted to open when the pressure (back pressure) of the back pressure chamber 110 becomes a predetermined value Pm or more, and the back pressure is maintained lower than the discharge pressure Pd. As a result, the back pressure becomes near the intermediate pressure Pm, which is less than the suction pressure Ps and the super discharge pressure Pd. When the compression by the first compression chamber 100a is started, the back pressure valve 26 is opened on the way, and the oil in the back pressure chamber 110 passes through.

［背圧室１１０からの油の分散］
上記のような構成により、背圧室１１０へ流入した油は、圧縮給油路６０を経由して第１の圧縮室１００aへ流入する。圧縮室側開口部６０ｂの位置は第１の圧縮室１００a内であれば特に限られないが、図２に例示するように、本実施例では外周寄りの部分に設けている。 [Dispersion of oil from back pressure chamber 110]
With the above configuration, the oil that has flowed into the back pressure chamber 110 flows into the first compression chamber 100a via the compression oil supply passage 60. The position of the opening 60b on the compression chamber side is not particularly limited as long as it is inside the first compression chamber 100a, but as illustrated in FIG. 2, it is provided in a portion closer to the outer periphery in this embodiment.

（第１の圧縮室１００aへの油の供給）
圧縮室側開口部６０ｂ近傍の固定スクロール２には、固定台板面２ｕ内周側に位置する環状凹部７０ｂ０と、旋回鏡板３ａの外周縁に位置する湾状凹部７０ｂ１とが設けられている。環状凹部７０ｂ０は、旋回鏡板３ａが旋回運動するときの掃引領域よりも大きい外径を有する環状、好ましくは円環状の部分である。湾状凹部７０ｂ１は、環状凹部７０ｂ０より内周側に位置し、固定ラップ２ｂの最外周部分に凹状、好ましくは湾状に食い込んだ部分である。湾状凹部７０ｂ１は、常に旋回鏡板３ａの外側まで広がっているため、背圧室１１０と常に連通している。これにより、第１の圧縮室１００a側に油が貯留される。 (Supply of oil to the first compression chamber 100a)
The fixed scroll 2 near the opening 60b on the compression chamber side is provided with an annular recess 70b0 located on the inner peripheral side of the fixed base plate surface 2u and a bay-shaped recess 70b1 located on the outer peripheral edge of the swivel end plate 3a. The annular recess 70b0 is an annular, preferably an annular portion, having an outer diameter larger than the sweep region when the swivel end plate 3a swivels. The bay-shaped recess 70b1 is located on the inner peripheral side of the annular recess 70b0, and is a portion that bites into the outermost peripheral portion of the fixed wrap 2b in a concave shape, preferably in a bay shape. Since the bay-shaped recess 70b1 always extends to the outside of the swivel end plate 3a, it always communicates with the back pressure chamber 110. As a result, oil is stored in the first compression chamber 100a side.

実施例1の効果は、背圧弁２６に係る圧力は第１の圧縮室１００a内の圧力のみとなり、背圧弁２６の押付力が均一となり、背圧弁２６の作動力が安定する。これにより、背圧弁２６により制御されている背圧室１１０内の圧力は変動することなく、旋回スクロール３は安定した圧力を受けることができる。 The effect of the first embodiment is that the pressure related to the back pressure valve 26 is only the pressure in the first compression chamber 100a, the pressing force of the back pressure valve 26 becomes uniform, and the operating force of the back pressure valve 26 becomes stable. As a result, the pressure in the back pressure chamber 110 controlled by the back pressure valve 26 does not fluctuate, and the swivel scroll 3 can receive a stable pressure.

また、第１の圧縮室１００aは第２の圧縮室１００ｂよりも旋回スクロール３中心に近い位置にあるため、第１の圧縮室１００aのみに給油することで、旋回スクロール３をフレーム４側へ引き離そうとする力、転覆モーメントを小さくすることができる。 Further, since the first compression chamber 100a is located closer to the center of the swivel scroll 3 than the second compression chamber 100b, the swivel scroll 3 is pulled away to the frame 4 side by refueling only the first compression chamber 100a. The force to try and the overturning moment can be reduced.

以上により、旋回スクロール３の揺動や離脱などが発生しにくくなり、体積効率および圧縮機効率の低下を抑制することができる。 As a result, the swivel scroll 3 is less likely to swing or come off, and it is possible to suppress a decrease in volumetric efficiency and compressor efficiency.

実施例１は第１の圧縮室１００aへの油の供給を説明したが、第２の圧縮室１００bへの油の供給としてもよい(図４、５)。 Although the first embodiment has described the supply of oil to the first compression chamber 100a, it may be the supply of oil to the second compression chamber 100b (FIGS. 4 and 5).

実施例２の効果は、背圧弁２６に係る圧力は第２の圧縮室１００ｂ内の圧力のみとなり、背圧弁２６の押付力が均一となり、背圧弁２６の作動力が安定する。これにより、背圧弁２６により制御されている背圧室１１０内の圧力は変動することなく、旋回スクロール３は安定した圧力を受けることができる。 The effect of the second embodiment is that the pressure related to the back pressure valve 26 is only the pressure in the second compression chamber 100b, the pressing force of the back pressure valve 26 becomes uniform, and the operating force of the back pressure valve 26 becomes stable. As a result, the pressure in the back pressure chamber 110 controlled by the back pressure valve 26 does not fluctuate, and the swivel scroll 3 can receive a stable pressure.

また、旋回スクロールの構造上、第２の圧縮室１００ｂは第１の圧縮室１００aよりも吸込圧力から吐出圧力に至る工程となる圧縮工程が長いため、第１の圧縮室１００aよりも第２の圧縮室１００ｂに連通した方が背圧弁２６の押付力が更に均一となる。 Further, due to the structure of the swirl scroll, the second compression chamber 100b has a longer compression step from the suction pressure to the discharge pressure than the first compression chamber 100a, so that the second compression chamber 100b is second than the first compression chamber 100a. The pressing force of the back pressure valve 26 becomes more uniform when it communicates with the compression chamber 100b.

以上により、旋回スクロール３の揺動や離脱などが発生しにくくなり、体積効率および圧縮機効率の低下を抑制することができる。 As a result, the swivel scroll 3 is less likely to swing or come off, and it is possible to suppress a decrease in volumetric efficiency and compressor efficiency.
