CONSTITUTION: A discharge device of a compressor consists of: a discharge valve(20) closely adhered to or separated from a discharge port(7a) depending on suction/discharge of refrigerant; and a pressure trap(21) having plural outflow ports forming limiting moving up of the discharge valve and flowing refrigerant through the discharge valve. When a rotor and a rotatable shaft(3) are rotated by a magnetic field, a cam and a roller(5) are rotated with eccentricity. Refrigerant is compressed in a cylinder(6) by the eccentric rotation and then discharged through the discharge port. To suck the refrigerant, the discharge valve is closely adhered to the upper face of the discharge port. When the refrigerant is compressed, the discharge valve rises up in the pressure trap to discharge the refrigerant through the plural outflow ports. The discharge valve is not distorted and durability is improved.

It is installed to rotate, the roller 5 is inserted into the outer side of the cam 3a eccentrically formed below the rotating shaft 3, the cam 3a and the roller 5 is the inner side of the cylinder (6) It is installed to be rotated in the upper and lower sides of the cylinder 6, the upper and lower flanges (7) (8) for rotatably supporting the rotating shaft (3) is fastened and fixed.

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 삽입설치되어 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. It is inserted and 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 접촉하면서 실린더(6)내의 공간을 흡입공간과 압축공간으로 구획하도록 상기 롤러(5)와 미끄럼접촉하는 베인(15)이 설치되어 있다.As shown in Fig. 2, the cylinder 6 has a roller (5) provided on the outer circumferential surface of the cam 3a eccentric to the lower end of the rotation shaft 3 while making a rolling contact with the inner circumferential surface of the cylinder 6; 6) A vane 15 is provided in sliding contact with the roller 5 so as to divide the space within the suction space and the compression space.

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. The valve stop 6d is provided to limit excessive bending.

이와 같이 구성된 압축기는 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)의 편심회전에 의해 실린더(6)의 내부에서는 베인(15)이 스프링(16)의 탄발작용에 의해 슬라이드 운동하면서 상기 롤러(5)의 외주면과 미끄럼접촉하여 흡입공간과 압축공간을 구획 형성하게 되는 바, 상기 캠(3a)이 시계방향으로 회전을 반복하면서 작용하는 흡입력에 의해 상기 어큐뮬레이터(10) 및 흡입관(11)을 거쳐 상기 흡입구(6a)를 통해 냉매가 흡입되고, 상기 토출구(6b)를 통해 고온 고압으로 압축된 냉매가 토출되어 진다.The compressor configured as described above includes a cam 3a which is integrally rotated with the rotation shaft 3 when the rotor 4 and the rotation shaft 3 rotate by a magnetic field formed by applying current to the stator 2. Due to the eccentric rotation of the roller 5, the vane 15 slides in contact with the outer circumferential surface of the roller 5 while the vane 15 slides due to the springing action of the spring 16 to form a suction space and a compression space. 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.

그러나, 상기한 바와 같은 종래의 압축기에 있어서, 상기 상부 플랜지(7)의 형성된 토출구(6b)의 상부에는 냉매의 흡입시 밀착되어 폐쇄되고 냉매의 토출시에는 상측으로 휘어져 토출구(6b)를 개방시키는 토출밸브(6c)가 설치되어 있는 바, 상기 토출밸브(6c)는 반복되는 냉매의 흡입 및 토출에 따라 일정한 휘어짐을 반복하기 때문에 변형되기 쉬울 뿐만 아니아 그 제작 및 가공이 어려워 생산성 및 내구 신뢰성이 저하되는 문제점이 있었다.However, in the conventional compressor as described above, the upper part of the discharge port 6b formed in the upper flange 7 is in close contact with the suction of the refrigerant and closed upward, and the discharge port 6b is opened when the refrigerant is discharged. Since the discharge valve 6c is provided, the discharge valve 6c is not only deformable because it repeatedly deflects due to repeated suction and discharge of the refrigerant, and is difficult to manufacture and process, thereby increasing productivity and durability. There was a problem of deterioration.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로써, 본 발명의 목적은 토출밸브의 취부구조 및 형상을 변경하여 압축기의 생산성 및 내구신뢰성을 향상시킨 압축기의 토출 장치를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a discharge device of the compressor to improve the productivity and durability of the compressor by changing the mounting structure and shape of the discharge valve. have.

상기와 같은 목적을 실현하기 위하여 본 발명에 의한 압축기의 토출 장치는, 실린더내에서 회전하는 캠에 의하여 냉매를 흡입하여 고온 고압으로 압축된 냉매를 토출구를 통해 토출하는 압축기에 있어서, 상기 실린더내에서 압축된 냉매가 상부플랜지에 형성된 상기 토출구의 상면에서 냉매의 흡입 및 토출에 따라 토출구에 밀착 및 이격되는 원형의 판으로 된 토출 밸브와, 상기 상부플랜지에 압입되며, 그 내측에 상기 토출 밸브의 삽입 공간이 형성되어 상기 토출 밸브의 상측 이동을 구속함과 동시에 상기 토출구를 통해 토출되는 냉매를 유출시키는 다수개의 유출구를 가진 프레셔 트랩을 포함함을 특징으로 한다.In order to achieve the above object, a compressor discharge apparatus according to the present invention is a compressor that sucks a refrigerant by a cam rotating in a cylinder and discharges a refrigerant compressed at high temperature and high pressure through a discharge port.
