It is fastened and fixed to the cylinder (6) together with the upper flange (7), so that one side of the cylinder (6) does not flow into the cylinder (6) of the compressor, the liquid refrigerant generated by the load variation due to the suction of the refrigerant An accumulator (10) for storing liquid refrigerant is connected via a suction pipe (11), and the refrigerant gas discharged through the muffler (9) is provided on the upper side of the case (1) outside the case (1). A discharge tube 12 for discharging the gas is connected.

상기 실린더(6)에는 상기 흡입관(11)이 연결되는 흡입구(6a)와, 후술하는 베인(15)을 중심으로 한 압축공간에서 압축된 냉매가스를 토출시키도록 상기 상부플랜지(7)의 토출구(7a)와 연결되는 위치에 형성된 실린더용 토출구(6b)가 형성되어 있고, 상기 상부플랜지(7)의 상면에는 흡입구(6a)를 통해 냉매가 흡입될 때는 상기 상부플랜지(7)의 토출구(7a)에 밀착되어 폐쇄되고, 압축시에는 토출구(6b, 7a)를 통해 압축가스가 토출되도록 개방되는 토출밸브(6c)가 설치되어 있다.The cylinder 6 has a suction port 6a to which the suction pipe 11 is connected and a discharge port of the upper flange 7 to discharge the refrigerant gas compressed in a compression space centering on the vane 15 to be described later. A cylinder discharge port 6b formed at a position connected to 7a is formed, and when the refrigerant is sucked through the suction port 6a on the upper surface of the upper flange 7, the discharge port 7a of the upper flange 7 is provided. Close to each other, the discharge valve (6c) is provided to open the compressed gas is discharged through the discharge ports (6b, 7a) at the time of compression.

상기 실린더(6)의 내벽에 형성된 토출구(6b)에는 토출되는 가스의 소음을 저감시키도록 공명기(30)가 형성되어 있다. 상기 공명기(30)는 상기 토출구(6b)로부터 일전 간격 이격되어 상기 실린더(6)의 상하단으로 관통 형성된 공명홀(31)과, 상기 공명홀(31)과 상기 토출구(6b)와 연통되는 관통공(32)이 형성되어 있다.The resonator 30 is formed in the discharge opening 6b formed in the inner wall of the cylinder 6 so as to reduce the noise of the discharged gas. The resonator 30 is a resonance hole 31 spaced apart from the discharge port 6b by a predetermined distance and penetrated through the upper and lower ends of the cylinder 6, and a through hole communicating with the resonance hole 31 and the discharge hole 6b. 32 is formed.

또한, 상기 회전축(3)의 내측에 형성된 오일상승통로(3b)에는 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. 상기 오일상승통로(3b)의 상단부에는 회전축(3)의 외주면으로 오일(13)이 흐르도록 오일공(3c)이 형성되어 있다.In addition, the oil rising path 3b formed inside the rotary shaft 3 is raised to supply the oil 13 stored in the case 1 to the inside of the cylinder 6 and the inside of the upper flange 7. The oil pick-up member 14 is inserted. An oil hole 3c is formed at the upper end of the oil rise passage 3b so that the oil 13 flows to the outer circumferential surface of the rotation shaft 3.

상기 회전축(3)에 형성된 캠(3a)의 외주에 삽입된 롤러(5)는 상기 실린더(6)의 내부에서 회전하게 되는 바, 상기 롤러(5)의 외주면과 접촉되어 실린더(6)내부를 흡입 공간과 압축공간으로 구획하도록 베인(15)이 실린더(6)의 슬롯(20)에 삽입되어 있고, 이 베인(15)의 일측에는 실린더(6)의 외주면에 형성된 삽입구멍(19)으로 삽입되어 베인(15)에 탄발력을 가하는 코일스프링(21)이 슬롯(20)내에 삽입되어 있다.The roller 5 inserted into the outer circumference of the cam 3a formed on the rotating shaft 3 rotates inside the cylinder 6, and contacts the outer circumferential surface of the roller 5 so that the inside of the cylinder 6 A vane 15 is inserted into the slot 20 of the cylinder 6 so as to divide into a suction space and a compression space, and one side of the vane 15 is inserted into an insertion hole 19 formed in the outer circumferential surface of the cylinder 6. The coil spring 21 is inserted into the slot 20 to apply elasticity to the vane 15.

이와 같이 구성된 압축기는 고정자(2)에 전류가 인가됨에 따라 형성되는 자장에 의해 회전자(4) 및 회전축(3)이 회전되면, 상기 실린더(6)의 내부에서는 상기 회전축(3)과 일체로 회전되는 캠(3a) 및 롤러(5)의 편심 회전되고, 이 편심 회전에 따라 상기 롤러(5)의 외주면에서 코일스프링(21)의 탄발력을 받아 미끄럼 접촉하는 베인(15)이 실린더(6) 내의 공간을 흡입공간과 압축공간을 구획 형성하게 된다. 즉, 상기 베인(15)은 상기 흡입관(11)이 연결된 흡입구(6a) 및 토출구(6b)의 사이에 설치되어 있어, 상기 캠(3a)이 토출구 방향으로 회전하면, 그 흡입력에 의해 상기 어큐뮬레이터(10) 및 흡입관(11)을 거쳐 상기 흡입구(6a)를 통해 냉매가 흡입되고, 상기 실린더(6)의 토출구(6b)로 고온 고압의 냉매가 토출된다.When the rotor 4 and the rotating shaft 3 are rotated by a magnetic field formed by applying current to the stator 2, the compressor configured as described above is integrally formed with the rotating shaft 3 inside the cylinder 6. The vane 15 which is eccentrically rotated of the cam 3a and the roller 5 which are rotated, and is in sliding contact with the elastic force of the coil spring 21 on the outer circumferential surface of the roller 5 according to the eccentric rotation is the cylinder 6. The space inside the compartment forms a suction space and a compression space. That is, the vane 15 is installed between the suction port 6a and the discharge port 6b to which the suction pipe 11 is connected, and when the cam 3a rotates in the discharge port direction, the accumulator ( The refrigerant is sucked through the suction port 6a via 10) and the suction pipe 11, and the high temperature and high pressure refrigerant is discharged to the discharge port 6b of the cylinder 6.

이 때, 상기 흡입구(6a)를 통해 냉매가 흡입될 때, 상기 상부플랜지(7)의 상면에 있는 토출밸브(6c)는 하강하여 토출구(6b)에 밀착되고, 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 in through the suction port 6a, the discharge valve 6c on the upper surface of the upper flange 7 descends to be in close contact with the discharge port 6b, and the refrigerant is compressed in the compressed space to discharge the discharge port. When discharging through 6b, the discharge valve 6c is bent upward to open the discharge port 6b.

그리고, 상기 회전축(3)의 작동에 따라 회전되는 오일픽업부재(14)는 케이스(1)내에 저류된 오일(13)을 상기 회전축(3)의 오일상승통로(3b)로 상승시키고, 이 상승된 오일은 상기 오일상승통로(3b)와 회전축의 외주면과 관통되어 있는 오일공(3c)을 통하여 실린더(6)의 내측이나 상부플랜지(7)의 내측으로 오일(13)을 공급함으로써 원활하게 상기 회전축(3)이 회전되도록 한다.Then, the oil pick-up member 14 which is rotated according to the operation of the rotary shaft 3 raises the oil 13 stored in the case 1 to the oil rising path 3b of the rotary shaft 3, The oil is smoothly supplied by supplying the oil 13 to the inside of the cylinder 6 or the inside of the upper flange 7 through the oil hole 3c penetrating through the oil rising passage 3b and the outer circumferential surface of the rotating shaft. The rotary shaft 3 is rotated.

상기 실린더(6)에서 압축된 압축 가스가 토출구(6b)로 토출될 때, 토출되는 가스는 공명기(30)의 관통홀(32) 및 공명홀(31)로 유입되면서 가스의 소음이 저감된다.When the compressed gas compressed in the cylinder 6 is discharged to the discharge port 6b, the discharged gas flows into the through hole 32 and the resonance hole 31 of the resonator 30, thereby reducing the noise of the gas.

그러나, 상기한 바와 같은 종래의 압축기의 공명장치는, 실린더(6)내에서 압축된 냉매 가스가 상기 공명기(30)에서 1차적으로 공명된 후 토출구(6b, 7a)를 통해 토출되기 때문에 그 소음이 저감되는 효과는 있으나, 토출 효율이 저하되는 문제점이 있었다.However, the resonance apparatus of the conventional compressor as described above, because the refrigerant gas compressed in the cylinder (6) is first resonated in the resonator (30) and is discharged through the discharge ports (6b, 7a), the noise This effect is reduced, but there is a problem that the discharge efficiency is lowered.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로써, 본 발명의 목적은 압축기의 공명기를 상부플랜지에 소결하여 형성함으로써 압축기의 압축 효율을 향상시킨 압축기의 공명장치를 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 resonance apparatus of the compressor to improve the compression efficiency of the compressor by sintering the compressor resonator formed on the upper flange. .
