본 고안은 냉매가스등의 가스를 압축하는 일측하는 압축기에 있어서 특히 흡입압력의 맥동을 저감하는 기구에 관한 것이다.The present invention relates to a mechanism for reducing the pulsation of suction pressure, in particular, on one side compressor that compresses gas such as refrigerant gas.
실린더블록에 여러개의 신린더 안지름을 형성하고, 이 실린더안지름의 각각에 피스톤을 끼워넣은 다음, 이 피스톤을 사판 등을 개재하여 각기 일정한 의상차를 가지고 왕복운동 시키는 형식의 압축기는 워블형, 스와사폴레이트형등이 잘알려져 있다. 이런 종류의 압축기에 있어서는 배관을 개재하여 차실내의 증발기에 전달 되어 이상음을 발생하는 원인으로 된다.Compressors are formed in a cylinder block with multiple inner diameters, and a piston is inserted into each of the inner diameters of the cylinder. Rate types and the like are well known. In this kind of compressor, it is transmitted to the evaporator in the vehicle via a pipe and causes abnormal sound.
그때문에 이 흡입압력의 백동을 저감하는 고안이 종래에 있어서도 여러가지가 제안되어 있었다. 그중의 하나로서, 일본국 특개소 58-9874호 공보로 공개 게재된 것이있다.For this reason, various proposals have been made in the related art for reducing the cupric of the suction pressure. One of them is published in Japanese Patent Laid-Open No. 58-9874.
이것은 흡입가스를 실린더헤드내의 저압실에 도입하는 흡입구에서 각 실린더안지름에 대응하여 밸브플레이트에 형성된 흡입구멍까지의 거리가 길어짐에 따라서 통로 저항을 작게 하고 각 실린더마다의 흡입가스량을 같게 하여 맥동의 평균화를 도모하고있다.As the distance from the inlet port through which suction gas is introduced into the low pressure chamber in the cylinder head to the suction hole formed in the valve plate corresponding to each cylinder diameter becomes longer, the passage resistance is reduced and the amount of gas in each cylinder is equalized so that the pulsation is averaged. Promoting
그런, 상기한 종래예에 있어서는 흡입구에서 각 흡입구멍까지의 거리가 다르므로 흡입압력의 맥동의 위상이 일치하여 이에 따라 그 맥동이 증폭되어서 커다란 이상음을 발생하는 일이 있었다.In such a conventional example, since the distance from the suction port to each suction hole is different, the phases of the pulsation of the suction pressure coincide with each other, so that the pulsation is amplified to generate a large abnormal sound.
그래서 본 고안은 흡입압력의 맥동이 일치하는 것을 방지하고 그렇게 함으로써 확실하게 그 맥동을 저감할 수 있도록 하는 것을 과제로 하고 있다.Therefore, the subject of the present invention is to prevent the pulsation of the suction pressure from coinciding and to reliably reduce the pulsation by doing so.
그리하여, 본 고안의 가장 특징으로 하는 바는 실린더헤드를 이 실린더헤드에 형성된 흡입구와 연통하는 제1저압실과 밸브플레이트의 흡입구멍과 연통하는 제2저압실과 밸브플레이트의 배출구멍 및 실린더헤드에 형성된 배출구와 연통하는 고압실로 분할 수다을 개재하여 분할하며, 또한 이 분할수단에 제1저압실과 제2저압실과를 연통하는 흡입연통구멍을 형성하여 이 흡입연통구멍이 적어도 2개의 흡입 구멍으로 부터 같은 거리로 한점에 있다.Thus, the most characteristic feature of the present invention is the first low pressure chamber communicating with the inlet formed in the cylinder head, the second low pressure chamber communicating with the suction hole of the valve plate, the discharge hole of the valve plate and the outlet formed in the cylinder head. The high pressure chamber communicates with the high pressure chamber, and divides it through a chattering section. In addition, a suction communication hole communicating with the first low pressure chamber and the second low pressure chamber is formed in the dividing means so that the suction communication hole is one point at the same distance from at least two suction holes. Is in.
따라서, 흡입구로부터의 흡입가수는 먼저 제1저압실에 유입된 다음, 분할수단의 흡입연통 구멍을 개재하여 제2저압실에 유입되고, 이 제2저압실에서 실린더로 흡압되는 것으로 흡입연통 구멍이 2개의 흡입구멍으로부터 같은 거리에 있으므로, 그 흡입연통 구멍을 통과하는 흡입가스의 시간이 차이져서 그로인하여 생기는 맥동에 의상차를 갖게 하여 그 때문에 상기한 바 과제를 달성할 수 있었다.Therefore, the suction singer from the suction port first flows into the first low pressure chamber, and then enters the second low pressure chamber via the suction communication hole of the dividing means, and the suction communication hole is sucked into the cylinder from the second low pressure chamber. At the same distance from the two suction holes, the time difference of the suction gas passing through the suction communication hole was different so that a pulsation caused by the suction gas was provided, thereby achieving the above-described problem.
다음에 본 고안의 실시예를 도면에 따라 설명한다. 제1도∼제4도에서 본 고안의 한실시예를 나타내었는바 압축기는 잘알려진 워블형으로서 실린더블록(1)에는 예컨데 5개의 실린더안지름(2)이 평행으로 형성되었으며, 각각의 실린더안지름(2)에 피스톤(3)의 피스톤 헤드(3a)가 각기 미끄러져 움직이기 자유롭도록 끼워 넣어져 있다.Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 shows an embodiment of the present invention, the compressor is a well-known wobble type, for example, five cylinder inner diameters 2 are formed in the cylinder block 1 in parallel, and each cylinder inner diameter ( 2) The piston head 3a of the piston 3 is fitted so that each slides freely.
피스톤헤드(3a)에는 피스톤로드(3b)가 연결되었고, 이 피스톤로드(3b)의 타단은 도해에 없는 시판에 걸어 맞추거나 그렇지 않으면 맞닿게 하고 있으며, 서로 이웃하는 피스톤(3)이 일정한 의상차로써 실린더안지름(2)내에서 왕복 운동하도록 되어 있다.A piston rod 3b is connected to the piston head 3a, and the other end of the piston rod 3b is engaged or otherwise abuts on the market, which is not illustrated, and the adjacent pistons 3 are uniformly outfitted. As a result, the cylinder reciprocates within the inside diameter 2.
밸브플레이트(4)는 실린더블록(1)와 나중에 설명하는 실린더헤드(5)와의 사이에 끼워져서 실린더헤드(5)와 함께 연결보울트(6)로 실린더블록(1)의 일단에 굳게 장착되어 실린더안지름(2)의 일단을 폐쇄하는 형태로 되어 있으며, 실린더안지름(2), 피스톤 헤드(3a)의 끝면 및 벨브플레이트(4)의 내면등으로 압축실(7)이 구성되어 있다.The valve plate 4 is sandwiched between the cylinder block 1 and the cylinder head 5 described later, and is firmly mounted to one end of the cylinder block 1 together with the cylinder head 5 by a connecting bolt 6. One end of the inner diameter 2 is closed, and the compression chamber 7 is constituted by the inner diameter of the cylinder 2, the end face of the piston head 3a, the inner surface of the valve plate 4, and the like.
이 밸브플레이트(4)에는 흡입구멍(8)과 배출구멍(9)이 실린더안지름(2)의 맞서는 부위에 각기 형성되었으며, 이 때문에 흡입구멍(8)과 배출구멍(9)과의 수는 각기 5개로 되어 있다.In the valve plate 4, the suction hole 8 and the discharge hole 9 are respectively formed in a portion where the cylinder diameter 2 is opposed to each other. Therefore, the number of the suction hole 8 and the discharge hole 9 is respectively different. There are five.
흡입구멍(8)은 실린더블록(1)와 밸브플레이트(4)와의 사이에 끼워진 별모양의 흡입밸브(10)에 의하여 폐쇄되어 있다.The suction hole 8 is closed by a star-shaped suction valve 10 sandwiched between the cylinder block 1 and the valve plate 4.
이 흡입밸브(10)는 개폐가 자유로우며, 피스톤(3)이 후퇴하여 압축실(7)의 용적을 확대하는 흡입행정에서는 흡입구멍(8)을 열고 압축실(7)에 가스를 흡입하며, 피스톤(3)이 전전하여 압측실(7)의 용적을 축소하는 압축배출 행정에서는 닫쳐진다.The suction valve 10 can be opened and closed freely, and in a suction stroke in which the piston 3 retracts to enlarge the volume of the compression chamber 7, the suction hole 8 is opened to suck gas into the compression chamber 7, The piston 3 is closed and is closed in the compression discharge stroke in which the volume of the pressure chamber 7 is reduced.
한편, 배추구멍(9)도 마찬가지로 별모양의 배출밸브(11)에 의하여 폐쇄되어 있으나, 밸브플레이트(4)의 표면에 마련되었으며, 이 배출밸브(11)의 등부분에는 밸브스토퍼(12)가 배치되었고, 이 밸브스토퍼(12)와 하께 부착나사(13)로써 실린더블록(1)에 고정되었으며, 흡입행정에서는 배출구멍(9)을 닫는데 반하여 압측배출 행정에서는 제한된 개구면적으로 배출구명(9)을 열도록 하고 있다.On the other hand, the cabbage hole (9) is similarly closed by a star-shaped discharge valve (11), but is provided on the surface of the valve plate (4), and the valve stopper (12) is provided at the back portion of the discharge valve (11). The valve stopper 12 is fixed to the cylinder block 1 with an attachment screw 13, and the suction hole 9 is closed in the intake stroke, whereas in the pressure discharge stroke, the outlet opening 9 is restricted. ) To open.
실린더헤드(5)는 부착나사(13)을 중심으로 하는 원형의 격벽(14)이 일체로 형성되었으며, 이 격벽(14)으로 실린더헤드내, 즉 밸브플레이트(4)와 실린더헤드(5)에 둘러쌓인 부분을 주연측의 저압공간(15)과 가운데축의 고압실(16)로 분할하고 있다.The cylinder head 5 has a circular partition 14 formed integrally with the attachment screw 13 integrally formed therein, and the partition 14 is formed in the cylinder head, that is, in the valve plate 4 and the cylinder head 5. The enclosed part is divided into the low pressure space 15 on the peripheral side and the high pressure chamber 16 on the middle axis.
고압실(16)은 밸브스토퍼(12)를 둘러쌓는 형태로 형성되어서 모든 배출구멍(9)과 연통한다.The high pressure chamber 16 is formed to surround the valve stopper 12 so as to communicate with all the discharge holes 9.
또, 이 고압실(16)은 실린더헤드(5)의 끝면 중앙에 형성된 배출구(17)와도 연통하고 있으며, 이 배출구(17)는 각 배출구멍(9)으로부터 위치에 있다.The high pressure chamber 16 also communicates with a discharge port 17 formed at the center of the end face of the cylinder head 5, and the discharge port 17 is positioned from each discharge hole 9.
저압공간(15)은 실린더헤드(5)의 내벽에 고정된 분할판(18)으로써 압축기의 길이방향으로 제1저압실(15a)과 제2저압실(15b)로 분할되어 있다.The low pressure space 15 is divided into a first low pressure chamber 15a and a second low pressure chamber 15b in the longitudinal direction of the compressor by a partition plate 18 fixed to the inner wall of the cylinder head 5.
제1저압실(15a)은 실린더헤드(5)와 분할판(18)으로 둘러쌓여서 구성되었으며, 실린더헤드(5)의 끝면에 형성된 흡입구(19)와 연통하고 있다.The 1st low pressure chamber 15a was comprised by the cylinder head 5 and the partition plate 18, and is in communication with the suction port 19 formed in the end surface of the cylinder head 5. As shown in FIG.
제2저압실(15b)은 밸브플레이트(4), 실린더헤드(5) 및 분할판(18)에 둘러쌓여서 구성되었으며, 모든 흡입구멍(8)과 연통하고 있다. 그리고 제1저압실(15a)과 제2저압실(15b)과는 분할판(18)에 형성된 흡입연통구멍(20)을 개재하여 연통하고 있다.The 2nd low pressure chamber 15b was comprised by the valve plate 4, the cylinder head 5, and the partition plate 18, and communicates with all the suction holes 8. As shown in FIG. The first low pressure chamber 15a and the second low pressure chamber 15b communicate with each other via the suction communication hole 20 formed in the partition plate 18.
이 흡입연통구멍(20)은 서로 이웃하는 흡입구멍(8),(8)에서 같은 거리에 있도록 주방향으로 일정간격을 두고 모두 5개를 형성하고 있다.The suction communication holes 20 are formed five at regular intervals in the circumferential direction so as to be at the same distance from the suction holes 8 and 8 adjacent to each other.
다음에 상기 실시예를 있어서의 작용에 대하여 설명한다. 더우기, 제1도 및 제3도에 백색의 화살표는 흡입가스의 흐름을 흑색의 화살표는 배출가스의 흐름을 각기 나타낸다.Next, the operation in the above embodiment will be described. Furthermore, in Figs. 1 and 3, the white arrows indicate the flow of intake gas and the black arrows indicate the flow of exhaust gas, respectively.
그리고 도해에 없는 구동축이 회전하면, 피스톤(5)이 각기 72도의 의상차로써 실린더안지름(2)을 왕복 운동한다. 각피스톤(3)이 흡입행정으로 들어가면 압축실(7)의 용적이 확대하므로 이 압축실(7)의 압력이 낮아지고, 흡입밸브(10)가 열려서 이 압축실(7)에 가스가 흡입된다. 이때 흡입가스는 흡입구(19)에서 제1저압실(15a)에 유입하여 이 제1저압실(15a)내에서 일시 저장되었다가 흡입연통구멍(20)을 개재하여 분배된 형태로 제2저압실(15b)에 이르며, 이 제2저압실(15b)에서 흡입구멍(8)을 개재하여 압축실(7)에 이른다.And when the drive shaft which does not show in figure rotates, the piston 5 reciprocates the cylinder inside diameter 2 by 72 degree | times, respectively. When the angular piston 3 enters the suction stroke, the volume of the compression chamber 7 is enlarged so that the pressure in the compression chamber 7 is lowered, and the suction valve 10 is opened to inhale gas into the compression chamber 7. . At this time, the suction gas flows into the first low pressure chamber 15a from the suction port 19 and is temporarily stored in the first low pressure chamber 15a, and is distributed through the suction communication hole 20 in the second low pressure chamber. 15b, it reaches the compression chamber 7 via the suction hole 8 in this 2nd low pressure chamber 15b.
다음에 배출행정으로 들어가면 압축실(7)의 압력이 높아져서 배출밸브(11)가 열리어, 고압으로된 배출가스가 배출구멍(9)으로부터 고압실(16)을 통하여 배출구(17)에서 배출된다.Next, when entering the discharge stroke, the pressure in the compression chamber 7 is increased so that the discharge valve 11 is opened, and the discharge gas with high pressure is discharged from the discharge port 17 through the high pressure chamber 16 from the discharge hole 9. .
상술한 바와 같이 흡입구(19)에서 흡입구멍(8)으로 이르기까지의 사이에 흡입가스가 흡입연통구멍(20)을 통과하지만 이 흡입연통구멍(20)은 서로 이웃하는 흡입구멍(8),(8)으로부터 같은 거리에 형성되어 있다.As described above, the suction gas passes through the suction communication hole 20 from the suction port 19 to the suction hole 8, but the suction communication hole 20 is adjacent to each other. It is formed at the same distance from 8).
따라서, 하나의 흡입연통구멍(20)에 있어서는 예컨데 좌측의 흡입구멍(8)으로 흡입가스의 흐름이 대략 끝났을 단계에서 우측의 흡입구멍(8)으로 흡입가스의 흐름이 개시되는데, 그 좌우의 흐름에는 피스톤(3)의 왕복 운동에 대응한 의상차가 생기므로 이 때문에 흡입압력의 맥동이 완충하는 것을 방지 할 수 있다.Therefore, in one suction communication hole 20, the flow of the suction gas is started to the suction hole 8 on the right side at the stage where the flow of the suction gas is almost finished to the suction hole 8 on the left side. Since a dressing difference corresponding to the reciprocating motion of the piston 3 is produced, it is possible to prevent the pulsation of the suction pressure from being buffered.
제5도에서, 본 고안의 다른 실시예를 나타낸 것으로, 전술한 실시예와 비교하면 실린더헤드(5)내를 분할하는 수단을 달리하고 있다.In FIG. 5, another embodiment of the present invention is shown, which differs in means for dividing the inside of the cylinder head 5 as compared with the above-described embodiment.
즉, 이 실시예에 있어서는 실린더헤드(5)를 제1실린더헤드(5a)와 제2실린더해드(5b)와의 2단으로 분할하였으며, 제1실린더헤드(5a) 내에 제1저압실(15a)과 제1고압실(16b)이 제1격벽(14a)으로써 구획형성되었고, 제2실린더헤드(5b)내에 제2저압실(15b)과 제2고압실(16b)이 제2격벽(14b)으로써 구획 형성되었는바, 제1저압실(15a) 및 제1고압실(16a)과, 제2저압실(15b) 및 제2고압실(16a)은 제2의 실린더헤드(5b)의 끝면으로서 분할되어 있다.That is, in this embodiment, the cylinder head 5 is divided into two stages of the first cylinder head 5a and the second cylinder head 5b, and the first low pressure chamber 15a in the first cylinder head 5a. And the first high pressure chamber 16b is partitioned by the first partition 14a, and the second low pressure chamber 15b and the second high pressure chamber 16b are located in the second cylinder head 5b. The first low pressure chamber 15a and the first high pressure chamber 16a, the second low pressure chamber 15b and the second high pressure chamber 16a are defined as end faces of the second cylinder head 5b. It is divided.
제2의 실린더헤드(5b)의 끝면에는, 흡입연통구멍(20) 이외에도, 제1고압실(16a)과 제2고압실(16b)과를 연통하는 배출연통구멍(12)이 형성되었으며, 이 배출연통구멍(21)을 개재하여 배출가스가 2단으로 배출되도록 되어 있다. 더우기 전술한 실시예와 동일부분에 대하여는 도면에 동일 부호를 부쳐서 그 설명을 생략하였다.On the end surface of the second cylinder head 5b, in addition to the suction communication hole 20, a discharge communication hole 12 communicating with the first high pressure chamber 16a and the second high pressure chamber 16b is formed. The exhaust gas is discharged in two stages through the discharge communication hole 21. Furthermore, the same parts as in the above-described embodiment are denoted by the same reference numerals in the drawings and the description thereof is omitted.
이상에서 설명한 바와 같이 본 고안에 의하면 혼힙구에서 흡입구멍으로 이르기까지에 흡입가스가 제1저압실, 흡입연통구멍 및 제2저압실을 통하도록 함과 동시에 흡입연통구멍을 흡입구멍으로부터 같은 거리에 형성하였으므로 흡입압력의 맥동의 의상이 일치하는 것을 방지할 수 있으며, 그 때문에 흡입압력의 맥동에 기초한 진동, 이상음의 발생을 저감할 수 있다.As described above, according to the present invention, the suction gas passes through the first low pressure chamber, the suction communication hole, and the second low pressure chamber from the horn to the suction hole and at the same distance from the suction hole. Since it is formed, it is possible to prevent the clothes of the pulsation of the suction pressure from matching to each other, so that the generation of vibration and abnormal sound based on the pulsation of the suction pressure can be reduced.
