The upper and lower sides of the cylinder member 13, the cylinder member Upper and lower flanges 15 and 17 are disposed to fix 13, and an upper portion of the main body 1 is provided with a discharge pipe 19 for discharging the refrigerant compressed by the cylinder member 13. The accumulator 20 separating the liquid refrigerant and the refrigerant gas is disposed outside the main body 1 so that only the refrigerant gas of the refrigerant evaporated in the evaporator (not shown) is supplied to the compressor.
상기 어큐믈레이터(20)는 외관을 형성하는 케이스부재(21)로 이루어져 있고, 상기 케이스부재(21)의 상단측에는 상기 케이스부재(21)의 내부로 흡입되도록 냉매의 흐름을 가이드하는 주입관(23)이 배설되어 있고, 상기 케이스부재(21)의 내측 하단측에는 냉매가스가 공급되도록 냉매가스의 흐름을 가이드하는 스탠드파이프(25) 및 실린더부재(13)의 일단에는 냉매가 실린더부재(13)로 흡입되도록 냉매의 흐름을 가이드하는 흡입관(27)이 배설되어 있다.The accumulator 20 includes a case member 21 forming an appearance, and an injection tube for guiding the flow of the refrigerant to be sucked into the case member 21 at an upper end side of the case member 21 ( 23 is disposed, and a coolant is provided at one end of the stand pipe 25 and the cylinder member 13 to guide the flow of the coolant gas so that the coolant gas is supplied to the inner lower end side of the case member 21. The suction pipe 27 which guides the flow of the refrigerant so as to be sucked in is provided.
상기 실린더부재(13)에는 냉매가 흡입되는 흡입구(13a)가 형성되어 있고, 상기 흡입구(13a)의 타측에는 상기 흡입구(13a)로 유입된 냉매가 압축된 후, 토출되는 토출구(13c)가 형성되어 있고, 상기 실린더부재(13)의 내측에는 상기 실린더부재(13)의내부를 흡입실 및 토출실로 구획시키는 베인부재(25)가 고정 배설되어 있고, 상기 롤러부재(11)의 일측에는 상기 베인부재(25)의 일단에 외삽되어 냉매의 누설을 방지하는 부쉬부재(27)가 상기 롤러부재(11)의 왕복운동에 연동되어 직선이동 가능케 삽설되어 있다.(도 2참조)The cylinder member 13 has a suction port 13a through which the refrigerant is sucked, and a discharge port 13c is formed on the other side of the suction port 13a after the refrigerant flowing into the suction port 13a is compressed. The vane member 25 which divides the inside of the cylinder member 13 into the suction chamber and the discharge chamber is fixedly disposed inside the cylinder member 13, and the vane is disposed on one side of the roller member 11. A bush member 27, which is extrapolated to one end of the member 25 and prevents leakage of refrigerant, is inserted so as to move linearly in conjunction with the reciprocating motion of the roller member 11 (see FIG. 2).
이와 같이 구성된 종래의 압축기는 전원이 인가되면 고정자(3)에 자장이 형성도고 상기 고정자(3)에 형성된 자장에 의해서 회전자(5)가 회전하게 되면, 상기 회전자(5)와 일체로 결착된 회전축(9)이 회전하게 됨으로써, 상기 회전축(9)의 일측에 배설된 편심축(7)도 연동하여 고속으로 회전하게 된다.In the conventional compressor configured as described above, when power is applied, a magnetic field is formed in the stator 3, and when the rotor 5 is rotated by the magnetic field formed in the stator 3, the compressor 5 is integrally bound with the rotor 5. As the rotated shaft 9 is rotated, the eccentric shaft 7 disposed on one side of the rotary shaft 9 also rotates at high speed.
상기 편심축(7)이 회전함에 따라 상기 편심축에 외삽되어 있는 롤러부재(11)가 실린더부재(13)내에서 왕복운동을 하고, 상기 롤러부재(11)의 일측에 삽설되어 있는 부쉬부재(27)가 베인부재(25)의 외측을 따라 직선 왕복 운동한다.As the eccentric shaft 7 rotates, the roller member 11 extrapolated to the eccentric shaft reciprocates in the cylinder member 13, and a bush member inserted into one side of the roller member 11 ( 27 reciprocates linearly along the outside of the vane member 25.
따라서, 실린더부재(13)의 일단부에 형성된 흡입구(13a)를 통해서 흡입된 냉매를 고온고압으로 압축하고, 상기 고온고압으로 압축된 냉매는 실린더부재(13)의 일측에 형성된 토출구(13c)를 통하여 상부플랜지(15)의 외측으로 토출된다.Therefore, the refrigerant sucked through the suction port 13a formed at one end of the cylinder member 13 is compressed to high temperature and high pressure, and the refrigerant compressed to the high temperature and high pressure discharges the discharge port 13c formed on one side of the cylinder member 13. It is discharged to the outside of the upper flange 15 through.
상기 상부플랜지(15)의 외측으로 토출된 냉매는 도시하지 않은 가이드통로를 따라 상부로 이동되어 본체(1)의 상측에 배설된 토출관(17)을 통해 압축기 외부로 토출되고 공지의 냉매사이클에 의해 순환된 후, 액냉매를 포함하는 냉매가스는 상기 어큐믈레이터(20)의 케이스부재(21)의 상측에 구비된 주입관(23)을 통하여 유입된다.The refrigerant discharged to the outside of the upper flange 15 is moved upward along the guide passage (not shown) and discharged to the outside of the compressor through a discharge pipe 17 disposed on the upper side of the main body 1, and the refrigerant is discharged to a known refrigerant cycle. After being circulated by the refrigerant gas, the refrigerant gas including the liquid refrigerant flows through the injection pipe 23 provided above the case member 21 of the accumulator 20.
상기 주입관(23)으로 유입된 액냉매 및 냉매가스는 화살표 방향을 따라 케이스부재(21)의 저면부로 유입되고 상기와 같이 유입된 액냉매와 냉매가스중 분리된 냉매가스는 케이스부재(21)의 내측 중앙부에 배설된 스탠드파이프(25)로 유입되어 흡입관(27)을 통과하여 실린더부재(13)의 내측으로 유입된다.The liquid refrigerant and the refrigerant gas introduced into the injection tube 23 flow into the bottom surface of the case member 21 in the direction of the arrow, and the refrigerant gas separated from the liquid refrigerant and the refrigerant gas introduced as described above is the case member 21. It is introduced into the stand pipe 25 disposed in the inner central portion of the through the suction pipe 27 is introduced into the cylinder member (13).
그러나, 이와 같이 구성된 종래의 압축기는 실린더부재(13)의 내측에 반달형상의 토출구(13c)가 형성되어 토출볼륨의 손실을 일으킨다는 문제점이 있었다.However, the conventional compressor configured as described above has a problem in that a half-moon-shaped discharge port 13c is formed inside the cylinder member 13, causing loss of discharge volume.
따라서, 본 고안은 상술한 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 흡입실 및 토출실을 구획하는 베인부재의 일단에 배설된 부쉬부재를 개선하여 토출볼륨의 손실을 줄이고, 베인부재 주위의 실링면적을 증가시킴으로써, 누설로 인한 압축효율이 저하되는 것을 방지하는 베인 고정형 로터리 압축기를 제공하는데 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to improve the bush member disposed at one end of the vane member for partitioning the suction chamber and the discharge chamber to reduce the loss of discharge volume, An increase in the sealing area around the vane member provides a vane stationary rotary compressor which prevents the compression efficiency due to leakage from being lowered.
