그리고, 상기 상부플랜지(7)의 상측에는 실린더(6)내에서 압축된 냉매가스를 토출시키는 머플러(9)가 체결고정되어 있으며, 상기 실린더(6)의 일측에는 냉매의 흡입에 따른 부하 변동으로 발생하는 액상의 냉매가 압축기의 실린더(6)내로 유입되지 않도록 액상의 냉매를 저장하는 어규뮬레이터(10)가 흡입관(11)을 개재하여 접속되어 있고, 상기 케이스(1)의 상측에는 상기 머플러(9)를 통하여 토출된 냉매가스를 케이스(1)의 외측으로 토출시키는 토출관(12)이 접속되어 있다.In addition, a muffler 9 for discharging the refrigerant gas compressed in the cylinder 6 is fastened and fastened to the upper side of the upper flange 7, and on one side of the cylinder 6, the load fluctuates due to the suction of the refrigerant. An accumulator 10 for storing the liquid refrigerant is connected via a suction pipe 11 so that the generated liquid refrigerant does not flow into the cylinder 6 of the compressor, and the muffler is disposed above the case 1. The discharge tube 12 which discharges the refrigerant gas discharged | emitted through 9 to the outer side of the case 1 is connected.
또한, 상기 회전축(3)의 내측에는 케이스(1)내에 저류된 오일(13)을 상승시켜 상기 실린더(6)의 내측 및 상부플랜지(7)의 내측등으로 공급하는 오일픽업부재(14)가 삽입 설치되어 있다.In addition, an oil pick-up member 14 which raises the oil 13 stored in the case 1 to the inside of the rotation shaft 3 and supplies the inside of the cylinder 6 and the inside of the upper flange 7 is provided. Insertion is installed.
도2에 도시된 바와 같이, 상기 실린더(6)에는 상기 회전축(3)의 하단에 편심된 캠(3a)의 외주면에 설치된 롤러(5)가 상기 실린더(6)의 내주면과 구름 접촉하도록 설치되어 있고, 상기 롤러(5)와 미끄럼 접촉하면서 실린더(6)내의 공간을 흡입 및 압축공간으로 구획하는 베인(15)이 실린더(6)의 내측벽에 그 중심을 향해 형성된 슬롯(16)내에 설치되어 있으며, 상기 베인(15)은 그 일측에 연결된 스프링(17)에 의해 슬롯(16)내의 측벽과 미끄럼접촉하고 있다.As shown in FIG. 2, the cylinder 6 is provided with a roller 5 provided on the outer circumferential surface of the cam 3a eccentrically disposed at the lower end of the rotating shaft 3 so as to be in contact with the inner circumferential surface of the cylinder 6. And a vane 15, which slides in contact with the roller 5 and partitions the space in the cylinder 6 into the suction and compression space, is provided in the slot 16 formed toward the center of the inner wall of the cylinder 6, The vane 15 is in sliding contact with the side wall in the slot 16 by a spring 17 connected to one side thereof.
즉, 상기 실린더(6)에는 상기 베인(15)의 일측에 냉매를 흡입하도록 상기 흡입관(11)과 연결된 흡입구(6a)가 형성되고, 상기 베인(15)의 타측에는 압축된 냉매가스가 토출되는 토출구(6b)가 형성되어 있다.That is, the cylinder 6 has a suction port 6a connected to the suction pipe 11 so as to suck the refrigerant on one side of the vane 15, and the compressed refrigerant gas is discharged to the other side of the vane 15. The discharge port 6b is formed.
도3에 도시된 바와 같이, 상기 실린더(6)내에서 고온 고압으로 압축된 냉매가 상기 토출구(6b)를 통해 토출될 때, 토출구(6b)의 상부에는 그 토출 냉매에 의해 상측으로 휘어져 상기 토출구(6b)를 개방하고 흡입시에는 폐쇄되도록 작동하는 토출밸브(6c)가 일측이 체결부재(99)에 의해 고정 설치되어 있고, 상기 토출밸브(6c)의 상측에는 상기 토출밸브(6c)의 상측으로 과도한 휘어짐을 제한하도록 밸브멈추개(6d)가 설치되어 있다.As shown in Fig. 3, when the refrigerant compressed at high temperature and high pressure in the cylinder 6 is discharged through the discharge port 6b, the discharge port 6b is bent upwards by the discharge refrigerant above the discharge port 6b. A discharge valve 6c which opens 6b and operates to be closed at the time of suction is fixedly installed at one side by a fastening member 99, and an upper side of the discharge valve 6c above the discharge valve 6c.

Bar is formed, the refrigerant is sucked through the inlet 6a via the accumulator 10 and the suction pipe 11 by the suction force acting while the cam (3a) is rotated in the clockwise direction, the discharge port Through 6b, the refrigerant compressed to high temperature and high pressure is discharged.
이 때, 상기 흡입구(6a)를 통해 냉매가 흡입될 때, 상기 토출구(6b)의 상면에 있는 토출밸브(6c)는 토출구(6b)에 밀착되어 토출구(6b)를 폐쇄시키고, 압축공간에서 냉매가 압축되어 토출구(6b)를 통해 토출시에는 상기 토출밸브(6c)는 상측으로 휘어지면서 토출구(6b)를 개방하게 된다.At this time, when the refrigerant is sucked through the suction port 6a, the discharge valve 6c on the upper surface of the discharge port 6b is in close contact with the discharge port 6b to close the discharge port 6b and the refrigerant in the compressed space. Is compressed and discharged through the discharge opening 6b, the discharge valve 6c is bent upwards to open the discharge opening 6b.
그리고, 상기 회전축(3)의 작동에 따라 회전되는 오일픽업부재(14)는 케이스(1)내에 저류된 오일(13)을 상승시켜 회전축(3)의 외주면을 통하여 토출시킴으로써 실린더(6)의 내측이나 상부플랜지(7)의 내측으로 오일(13)을 공급하여 원활한 회전 작동이 이루어지게 되는 것이다.In addition, the oil pick-up member 14 rotated according to the operation of the rotating shaft 3 raises the oil 13 stored in the case 1 and discharges it through the outer circumferential surface of the rotating shaft 3 to thereby form the inner side of the cylinder 6. Or by supplying the oil (13) to the inside of the upper flange (7) is a smooth rotation operation is made.

다음에, 이와 같이 구성된 본 발명의 작용을 설명한다.Next, the operation of the present invention configured as described above will be described.
고정자(2)에 전류가 인가됨에 따라 형성되는 자장에 의해 회전자(4) 및 회전축(3)이 회전 작동하면, 상기 회전축(3)과 일체로 회전되는 캠(3a) 및 롤러(5)가 편심 회전하게 되고, 상기 롤러(50의 외주면에는 상기 실린더(6)의 내주면 일측에 형성된 슬롯(16)내에서 스프링(17)의 탄발력에 따라 슬라이딩되는 베인(15)이 미끄럼 접촉하여 흡입구(6a)가 형성된 흡입공간과 토출구(6b)가 형성된 토출공간을 구획하게 된다.When the rotor 4 and the rotating shaft 3 are rotated by a magnetic field formed by applying current to the stator 2, the cam 3a and the roller 5 which are integrally rotated with the rotating shaft 3 are The vane 15 slid in contact with the elastic force of the spring 17 in the slot 16 formed on one side of the inner circumferential surface of the cylinder 6 is eccentrically rotated, and the suction port 6a ) And the discharge space in which the suction space and the discharge port 6b are formed.
이 때, 상기 롤러(5)와 접촉되는 베인(15)은 압축공간 즉, 토출구(6b)가 형성된 공간으로부터 흡입공간 즉, 흡입구(6a)가 형성된 공간으로 냉매를 압축하게 되고, 이 압축된 냉매는 토출구(6b)를 통해 토출되어 상기 상부플랜지(7)의 상면에 결착된 토출밸브(6c)를 통해 토출되는 바, 이 냉매는 토출되는 과정에서 소음이 발생하게 된다.At this time, the vane 15 in contact with the roller 5 compresses the refrigerant from the compression space, that is, the space in which the discharge port 6b is formed, to the suction space, that is, the space in which the suction port 6a is formed. Is discharged through the discharge port 6b and discharged through the discharge valve 6c attached to the upper surface of the upper flange 7, and the refrigerant generates noise during the discharge process.
이 냉매는 상부플랜지(7)와 머플러용 상부부재(21)의 사이에서 그 토출 소음이 감쇠되는 데, 상기 토출밸브(6c)를 거쳐 나온 냉매는 상부플랜지(7)의 중앙부를 향하는 배플 돌기(20)들을 거쳐 상기 머플러용 상부부재(21)에 형성된 토출구멍(21a)을 통해 토출됨으로써 그 토출소음이 저감되는 것이다.The refrigerant is attenuated by the discharge noise between the upper flange 7 and the upper member 21 for the muffler, and the refrigerant passing through the discharge valve 6c has a baffle protrusion toward the center of the upper flange 7 ( Discharge noise is reduced by discharging through the discharge hole 21a formed in the upper member 21 for the muffler through the 20.
상기한 바와 같이, 본 발명에 의한 압축기용 상부플랜지의 소음 감쇠 장치에 의하면, 상기 상부플랜지를 압축기의 본체내에 용접 결착하고, 상부플랜지의 상면에 다수의 배플 돌기를 형성하고, 상부플랜지의 상부에 토출구멍을 가진 머플러용 상부부재를 설치하여 구성함으로써 실린더의 조립시 용접으로 인한 실린더의 변형을 방지함과 동시에 소음기의 형상을 상부플랜지에 일체로 소결하여 제작함으로써 제작비가 절감되며, 토출소음을 감쇠시키는 효과가 있다.As described above, according to the noise attenuation apparatus of the upper flange for the compressor according to the present invention, the upper flange is welded and bound in the main body of the compressor, a plurality of baffle projections are formed on the upper surface of the upper flange, and the upper flange By installing the upper member for the muffler with the discharge hole, it prevents the deformation of the cylinder due to welding during the assembly of the cylinder and simultaneously manufactures the silencer by sintering the shape of the silencer into the upper flange to reduce the manufacturing cost and reduce the discharge noise. It is effective to let.
