본 발명은 자동차용 공조장치의 냉매압축기로 사용되는 베인형 압축기에 관한 것이다.The present invention relates to a vane type compressor used as a refrigerant compressor of a vehicle air conditioner.

종래, 피압축가스의 흡입량을 조절하므로서 압축기의 능력을 가변제어할 수 있도록한 소위 가변용량셕 베인형 압축기로서 일본국 특개소 62-129523호 공보가 공지되어 있다.Conventionally, Japanese Patent Application Laid-Open No. 62-129523 is known as a so-called variable displacement vane type compressor that allows variable control of the compressor's ability by adjusting the suction amount of the compressed gas.

이러한 종래의 베인형 압축기는 제4도에서 나타냄과 같이 원형로우터(a)가 끼워진 로우터실(b)의 내주면을 타원형으로 한 캠링(c)과 제6도에서 나타냄과 같이 외주면부대칭위에 흡입구(d)에서 흡입한 피압축가스를 저압실축으로 누출시키는 절결부(e,e)를 갖고, 또한 저압실측압력과 고압실측압력의 차에 따라 정역 회전하여 전기절결부(e)의 위치를 변환시켜서, 압축개시시기를 변화시키므로서 토출용량을 가변 제어하는 회동제어판(f)을 구비한 것이다.Such a conventional vane type compressor has an inlet opening on the outer circumferential surface symmetry as shown in FIG. 6 and an elliptical cam ring (c) having an elliptical inner surface of the rotor chamber (b) into which the circular rotor (a) is fitted. has a cutout portion (e, e) for leaking the compressed gas sucked in d) to the low pressure chamber, and reversely rotates according to the difference between the low pressure measurement pressure and the high pressure measurement pressure to change the position of the electric cutout (e). And a rotation control plate f which variably controls the discharge capacity while varying the compression start time.

그리고, 로우터(a)가 제4도중 반시계방향으로 회전하므로서, 압축식(h)의 용적을 순차 확대하는 흡입행정에서 피압축가스가 흡입구(d)에서 서로 인접하는 베인(g,g)간에 흡입된 후, 압축실(h)의 용적을 축소하는 압축행정이고 전기 피압축가스가 압축되어서 토출구(j)에서 토출되는 것이다.Then, in the intake stroke in which the rotor a rotates counterclockwise in the fourth degree, the compressed gas h sequentially expands between the vanes g and g adjacent to each other at the inlet d. After being sucked in, it is a compression stroke that reduces the volume of the compression chamber h, and the electric gas to be compressed is compressed and discharged from the discharge port j.

전기회동제어판(f)이 토출용량방향(제4도중 시계방향)으로 최대한 회동하였을때, 절결부(e)의 양단부(e1,e2)가 흡입구(d)의 양단부(d1,d2)와 대응하게 위하하여서 압축개시점은 제4도중 (가)의 부분으로 되고, 토출용량 최대(전가동상태)로 됨, 또 전기회동제어판(f)이 토출용량 감소방향(제4도중 반시계방향)으로 최대한 회동하였을때 제5도에서 나타냄과 같이 절결부(e)의 양단부(e1,e2)가 흡입구(d)의 로우터 회전 방향전측단(d1)으로 부터 로우터 회전 방향측에 위치하고, 압축개시점 제5도중 (나)의 부분이 되어 토출용량최소로 됨. 이러한 토출용량최소운전시에 있어서, 전기절결부(e)의 로우터 회전방향후측단(e2)은 흡입구(d)의 로우터 회전방향전측단(d1)보다 거리 L만큼 로우터 회전방향전측에 편위되어 있기 때문에 이 거리 L 사이에 있어서 피압축가스가 베인(g)으로 눌러졌을때 옆으로 빠져나갈때가 없어서 여분의 압축작용이 행하여져서 이 압축작용이 로우터(a)의 회전에 대한 저항이 되고 있었다.When the electric rotation control plate f is rotated as far as possible in the discharge capacity direction (clockwise in FIG. 4), both ends e 1 and e 2 of the cutout e are opposite ends d 1 and d 2 of the suction port d. ), The compression start point becomes part of (a) in FIG. 4, the discharge capacity is maximum (full operating state), and the electric rotation control panel f is in the discharge capacity decreasing direction (counterclockwise during the fourth view). Direction), as shown in FIG. 5, the both ends e 1 and e 2 of the cutout e extend from the front end of the rotor rotation direction d 1 to the rotor rotation direction side as shown in FIG. It is located in the fifth part of compression starting point (B) and discharge capacity is minimum. In this discharge capacity minimum operation, the rotor rotation direction rear end e 2 of the electrical cutout e is biased in the rotor rotation direction front side by a distance L from the rotor rotation direction front end d 1 of the suction port d. Therefore, when the compressed gas is pushed by the vanes (g) between these distances L, there is no time to escape to the side, and an extra compression action is performed, and this compression action becomes a resistance to the rotation of the rotor a. .

본 발명은 상기 사정에 비추어서 착안한 것이고, 토출용량 최소시에 있어서의 여분의 압축작용을 삭제하고, 로우터의 회전에 대한 저항을 제거할 수 있도록 한 베인형 압축기를 제공하는 것을 목적으로 한다.The present invention has been conceived in view of the above circumstances, and an object of the present invention is to provide a vane-type compressor capable of eliminating the extra compression action at the minimum discharge capacity and eliminating the resistance to the rotation of the rotor.

상술한 문제점을 해결하기 위하여, 본 발명의 베인형 압축기는 원형로우터가 끼워진 로우터실내주면을 타원형으로한 캠링과 외주연부에 흡입구로 흡입된 피압축가스를 저압실측으로 누출시키기 위한 절결부를 갖고 또 저압실측 압력과 고압실측 압력의 차에 따라 정역회전하여 전기 절결부의 위치를 변화시켜서 압축개시시기를 변화시키므로서 토출용량을 가변제어하는 회동제어판을 구비한 베인형 압축기에 있어서, 전기회동제어판의 절결부는 그 회전방향전측단에서 거의 중간부까지의 제1부분과 이 거의 중간부에서 회전방향후측단에 이르는 제2부분으로 되고, 전기 제2부분과 전기회동제어판의 회동축심과의 사이의 거리를 전기 제1부분과 전기회동제어판의 회동축심과의 사이의 거리보다 길게 설정하고, 전기회동제어판이 토출용량증가방향으로 최대한 회동하였을때 전기 제1부분의 양단부는 전기흡입구의 양단부와 대응되게 위치함과 동시에 전기 제2부분의 로우터의 회전방향전측단부는 전기흡입구의 전기로우터 회전방향후측단부와 대응되게 위치하고, 또한 로우터 회전방향후측단부는 전기토출구와 대응되게 위치하고, 또 전기회동제어판이 토출용량감방향에 최대한 회동하였을때, 전기 제1부분의 양단부는 전기흡입구의 로우터 회전방향전측단에서 로우터 회전방향전측에 위치함과 동시에 전기 제2부분의 로우터 회전방향전측단부는 전기흡입구의 로우터 회전방향전측단에서 로우터 회전방향전측에 위치하고 또한 로우터 회전방향후측단부는 전기흡입구의 로우터 회전방향전측단에서 로우터 회전방향 후측에 위치할 수 있도록 구성한 것을 특징으로 한 것이다.In order to solve the above problems, the vane type compressor of the present invention has a cam ring having an elliptical shape of the inner circumference of the rotor chamber into which the circular rotor is fitted, and a cutout for leaking the compressed gas sucked into the low pressure chamber to the low pressure chamber. A vane-type compressor having a rotational control panel for varying the discharge capacity by varying the position of electrical cutout by changing the position of the electrical cutout by changing the position of the electrical cutout according to the difference between the low pressure chamber pressure and the high pressure chamber pressure. The notch consists of a first part from the front end of the rotational direction to the middle part and a second part from the almost middle part to the rear end of the rotation direction, and between the second electric part and the pivot shaft of the electric rotation control panel. The distance is set longer than the distance between the first electric part and the pivot center of the electric rotating control plate, and the electric rotating control panel is in the direction of increasing discharge capacity. When the motor is rotated as far as possible, both ends of the first electric part are positioned to correspond to both ends of the electric suction port, and at the same time, the front end of the rotational direction of the rotor of the second electric part is located to correspond to the rear end of the electric rotor rotation direction of the electric suction port. The rear end of the rotor rotational direction is located to correspond to the electric discharge port, and when the electric rotation control panel is rotated to the discharge capacity reduction direction as much as possible, both ends of the first electric part are located at the front of the rotor rotational direction at the front end of the rotor rotational direction of the electric suction port. At the same time, the front end of the rotor rotation direction of the second electric part is located at the front of the rotor rotation direction at the front end of the rotor rotation direction of the electric suction port, and the rear end of the rotor rotation direction is located at the rear of the rotor rotation direction at the front end of the rotor rotation direction of the electric suction port. It is characterized in that it is configured to be located.

토출용량 최소운전시, 절결부의 제2부분의 로우터 회전방향후측단이 흡입구의 로우터 회전방향전측단에서 로우터 회전방향후측에 위치하기 때문에 베인으로 눌린 피압축 가스는 제2부분에서 빠져나가기 때문에 여분의 압축작용은 행하여지지 않는다.During the minimum discharge capacity operation, the compressed gas pressed by the vane escapes from the second part because the rear end of the rotor direction in the second part of the cutout is located behind the rotor in the rotor direction in front of the rotor rotation direction. The compression action of is not done.

이하, 본 발명의 한 실시예를 제1도 내지 제3도에 의하여 설명한다.Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

It is a top view of the rotation control panel.

제1도 및 제2도중 (1)은 캠링이고, 그 로우터실(2)은 타원형으로 되어, 이 로우터실(2)내에 원형로우터(3)가 회전축(4)으로 회전이 자유롭게 장착되어 있다.1 and 2 are cam rings, and the rotor chamber 2 becomes elliptical, and the circular rotor 3 is rotatably mounted to the rotation shaft 4 in this rotor chamber 2.

전기캠링(1)의 로우터실(2)의 장축방향 양측에 위치하고 이 로우터실(2)의 내주면과 로우터(3)의 외주면의 사이에 압축식(6,6)이 획성되어 있다.Compression expressions 6 and 6 are defined between the inner circumferential surface of the rotor chamber 2 and the outer circumferential surface of the rotor 3 and located on both sides of the rotor chamber 2 of the electric cam ring 1.

전기캠링(1)의 단축방향 양측에는 토출구(7,7)가 설치되어 있다.Discharge ports 7 and 7 are provided on both sides of the electric cam ring 1 in the short axis direction.

전기캠링(1)의 양측에는 그 로우터실(2)의 장축부와 단축부의 사이에 위치하여서 흡입구(8,8)가 설치되어 있다.On both sides of the electric cam ring 1, suction ports 8 and 8 are provided between the long shaft portion and the short shaft portion of the rotor chamber 2.

전기캠링(1)의 축방향 한쪽면에는 회전제어판(9)이 정역회동이 자유롭게 설치되어 있다. 이 회동 제어판(9)은 제3도에서 나타냄과 같이 외주연부 양측 대칭위치에 절결부(10,10)를 가지고 있다.On the one axial side of the electric cam ring 1, the rotation control plate 9 is provided with forward and reverse rotation freely. This rotating control panel 9 has cutouts 10 and 10 at symmetrical positions on both sides of the outer periphery as shown in FIG.

이들 절결부(10)는 동일 구성으로서 회전방향전측단에서 거의 중간부에까지 이르는 제1부분(11)과 거의 중간부에서 회전방향후측단까지 이르는 제2부분(12)으로 되어 있다.These notches 10 have the same structure as the 1st part 11 which extends from a front end side to a substantially middle part in a rotation direction, and the 2nd part 12 which extends to a rear end side in a rotation direction from a substantially middle part.

전기 제2부분(12)과 전기회동제어판(9)의 회동축심과의 거리 L1을 전기 제1부분(11)과 전기회동제어판(9)의 회동축심과의 거리 L2보다 길게 설정하고 있다.The distance L 1 between the rotational shaft core of the electric second part 12 and the electric rotation control panel 9 is set longer than the distance L 2 between the rotation shaft core of the electric first part 11 and the electric rotation control plate 9. .

전기회동제어판(9)이 토출용량 증방향으로 최대한 회동하였을때 전기 제1부분(11)의 양단부(11a,11b)는 제1도에서 나타냄과 같이 전기흡입구(8)의 양단부(8a,8b)와 대응되게 위치함과 동시에 전기 제2부분(12)의 로우터 회전방향전측단부(12a)와 전기흡입구(8)의 로우터 회전방향후측단부(8b)와 대응 위치하고 또한 로우터 회전방향후측단부(12b)는 전기토출구(7)와 대응되게 위치한다.When the electric rotation control panel 9 is rotated as far as the discharge capacity increase direction, both ends 11 a and 11 b of the first electric part 11 are both ends 8 a of the electric suction port 8 as shown in FIG. 8 b ) and corresponding to the rotor rotation direction front end 12 a of the electric second part 12 and the rotor rotation direction rear end 8 b of the electric suction port 8 and correspondingly rotate the rotor. The direction rear end 12 b is located to correspond to the electrical discharge port 7.

또, 전기회동제어판(9)이 토출 용량감방향으로 최대한 회동하였을때 전기 제1부분(11)의 양단부(11a,11b)는 제2도에 나타냄과 같이 전기흡입구(8)의 로우터 회전방향전측단부(8a)에서 로우터 회전방향전측에 위치함과 동시에 전기 제2부분(12)의 로우터 회전방향전측단부(12a)는 전기흡입구(8)의 로우터 회전방향전측단부(8a)에서 로우터 회전방향전측에 위치하고, 또한 로우터 회전방향후측단부(12a)는 전기흡입구(8)의 로우터 회전방향후측단부(8b)에서 로우터 회전방향 후측에 위치한다.In addition, when the electric rotation control panel 9 is rotated as far as possible in the discharge capacity reduction direction, both ends 11 a and 11 b of the electric first part 11 rotate the rotor of the electric suction opening 8 as shown in FIG. direction of the front end (8 a) the rotor the rotor rotating direction of the rotary position, and at the same time electricity second portion 12 to the front side a front end in (12 a), the direction in the rotor rotation of the electric air inlet (8) the front end (8 a) located on the front side in the rotor rotation direction, and also the rotor rotating direction of the rear end portion (12 a) is located in the rotor rotating direction of the rear side in the rotor rotation the rear ends (8 b) the direction of the electric air inlet (8).

다음에 상기 구성으로 되는 본 발명의 베인형 압축기의 작동을 설명한다.Next, the operation of the vane compressor of the present invention having the above configuration will be described.

저압실(흡입실)측 압력이 소정치 이상으로 되면 회동제어판(9)이 저압실측 압력의 작용으로 토출용량증방향(제2도중 시계방향)으로 회동하여서 제1도의 상태로 되고, 압축개시점은 제1a도의 부분이 되고, 토출 용량최대(전가동)로 된다.When the pressure in the low pressure chamber (suction chamber) becomes equal to or higher than a predetermined value, the rotation control plate 9 rotates in the discharge capacity increase direction (clockwise in the second direction) under the action of the low pressure chamber pressure, and becomes the state of FIG. Becomes part of FIG. 1A, and becomes the discharge capacity maximum (full operation).

또, 저압실측 압력이 소정치 이하로 되면 회동제어판(9)이 고압실(토출실)측 압력의 작용으로 토출용량감방향(제1도중 반시계방향)으로 회동하여서 제2도의 상태가 되고 압축개시점은 제2b도의 부분이 되고, 토출용량최소(일부가동)로 된다.When the pressure in the low pressure chamber side is lower than or equal to a predetermined value, the rotation control panel 9 rotates in the discharge capacity reducing direction (counterclockwise in FIG. 1) under the action of the pressure in the high pressure chamber (discharge chamber) to be in the state of FIG. The starting point becomes a part of FIG. 2B, and the discharge capacity minimum (partially movable).

이러한 토출용량 최소 운전시에 있어서는 절결부(10)의 제2부분(12)의 로우터 회전방향후측단부(12b)가 흡입구(8)의 로우터 회전방향전측단부(8b)로부터 회전방향후측으로 위치하고 있기 때문에 베인(5)에서 피압축가스가 눌러도 이 피압축가스는 제2부분(12)에서 즉시 빠지기 때문에 여분의 압축작용은 행하여지지 않는다.In the minimum operation of the discharge capacity, the rotor rotation direction rear end portion 12 b of the second portion 12 of the cutout 10 is rotated rearward from the rotor rotation direction front end portion 8 b of the suction port 8. Since it is located, even if the compressed gas is pressed in the vane 5, the compressed gas is immediately removed from the second part 12, so that no extra compression action is performed.

따라서 로우터(3)의 회전에 대한 저항은 감소된다. 상술한 바와같이, 본 발명의 베인형 압축기는 원형로우터가 끼워진 로우터실 내주면을 타원형으로 한 캠링과 외주연부에 흡입구에서 흡입된 피압축가스를 저압실측으로 누출시키기 위한 절결부를 갖고, 또한 저압실측압력과 고압실측압력의 차에 따라 정역회동하여서 전기절결부의 위치를 변화시켜서 압축개시시기를 변화시키므로서 토출용량을 가변 제어하는 회동제어판을 구비한 베인형 압축기에 있어서, 전기회동제어판의 절결부는 그 회전방향전측단에서 거의 중간부에 이르는 제1부분과 이 거의 중간부에서 회전방향후측단에 이르는 제2부분으로 되고, 전기 제2부분과 전기회동제어판의 회동축심과의 사이의 거리를 전기 제1부분과 전기회동제어판의 회동축심과의 사이의 거리보다 길게 설정하고, 전기회동제어판이 토출용량방향으로 최대한 회동하였을때 전기 제1부분의 양단부는 전기흡입구의 양단부와 대응되게 위치함과 동시에 전기 제2부분의 로우터의 회전 방향 전측단부는 전기흡입구의 전기로우터 회전방향후측단부와 대응되게 위치하고, 또한 로우터 회전방향후측단부는 전기토출구와 대응되게 위치하고, 또 전기회동제어판이 토출용량 감방향에 최대한 회동하였을때, 전기 제1부분의 양단부는 전기흡입구의 로우터 회전방향전측단에서 로우터 회전방향전측에 위치함과 동시에 전기 제2부분의 로우터 회전방향전측단부는 전기흡입구의 로우터 회전방향전측단보다 로우터 회전방향전측에 위치하고 또한 로우터 회전방향 우측단부는 전기흡입구의 로우터 회전방향전측단보다 로우터 회전방향 후측에 위치하도록 구성한 것을 특징으로 한 것이다.Thus, the resistance to the rotation of the rotor 3 is reduced. As described above, the vane-type compressor of the present invention has a cam ring having an elliptical shape of the inner circumferential surface of the rotor chamber into which the circular rotor is fitted, and a cutout for leaking the compressed gas sucked from the suction port to the low pressure chamber side at the outer peripheral portion thereof, In the vane type compressor having a rotation control panel for varying the discharge capacity by varying the position of the electrical cutout by changing the position of the electrical cutout by reverse rotation according to the difference between the pressure and the high pressure measured pressure, the cutout portion of the electric rotation control plate Is the first part extending from the front end of the rotational direction to the almost middle part and the second part reaching the rear end of the rotational direction from the almost middle part thereof, the distance between the second electric part and the pivot axis of the electric rotation control panel. It is set longer than the distance between the first electric part and the pivot axis of the electric rotation control panel, and the electric rotation control panel is When rotated, both ends of the first electric part are located to correspond to both ends of the electric suction port, and at the same time, the front end part of the rotor in the second direction of rotation of the electric second part is located to correspond to the rear end of the electric rotor rotation direction of the electric suction part. The rear end of the direction is located to correspond to the electric discharge port, and when the electric rotation control panel is rotated to the discharge capacity reduction direction as much as possible, both ends of the first electric part are located at the front of the rotor rotation direction at the front end of the rotor rotation direction of the electric suction port. At the same time, the front end of the rotor rotation direction of the second electric part is located on the front side of the rotor rotation direction than the front end of the rotor rotation direction of the electric suction port, and the right end of the rotor rotation direction is located on the rear side of the rotor rotation direction than the front end of the rotor rotation direction of the electric suction port. It is characterized by the configuration.

따라서, 토출용량최소운전시, 절결부의 제2부분의 로우터 회전방향후측단이 흡입구의 로우터 회전방향전측단보다 로우터 회전방향후측에 위치하기 때문에 베인으로 눌린 피압축가스는 제2부분에서 빠져 나가기 때문에 여분의 압축작용은 행하여지지 않고, 로우터의 회전에 대한 저항이 감소한다는 효과를 성취한다.Therefore, during the minimum discharge capacity operation, the compressed gas pressed by the vane escapes from the second part because the rear end of the rotor in the second direction of the cutout is located behind the rotor in the rotor direction of the inlet. Because of this, no extra compression is done and the effect of reducing the rotor's resistance to rotation is achieved.
