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.

또한, 상기 회전축(3)의 내측 회전 중심에 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 at the inner rotational center of the rotary shaft 3 raises the oil 13 stored in the case 1 so that the inside of the cylinder 6 and the inside of the upper flange 7 and the like. The oil pick-up member 14 to be supplied 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.

도2에 도시된 바와 같이, 상기 오일상승통로(3b)는 상기 회전축(3)의 중심선(O)상에 위치되어 있고, 참조 부호 E는 편심축(3a)의 중심선이고, W는 편심축(3a)을 포함한 회전축(3) 전체의 무게중심선이다.As shown in Fig. 2, the oil rising passage 3b is located on the center line O of the rotation axis 3, reference E is the center line of the eccentric shaft 3a, and W is the eccentric shaft ( It is the center of gravity line of the whole rotating shaft 3 including 3a).

여기서, 회전축(3)의 중심선(O)과 무게 중심선(W)과의 거리는 R1으로 표시된다.Here, the distance between the center line O and the center of gravity line W of the rotation shaft 3 is represented by R1.

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 편심축(3a) 및 롤러(5)의 편심 회전되고, 이 편심 회전에 따라 상기 롤러(5)의 외주면에서 코일스프링(도시안됨)의 탄발력을 받아 미끄럼 접촉하는 베인이 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 편심축(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, which is eccentrically rotated by the eccentric shaft 3a and the roller 5, which is rotated and is in sliding contact with the elastic force of the coil spring (not shown) on the outer circumferential surface of the roller 5 according to the eccentric rotation.

The rotary shaft 3 is rotated.

그러나, 상기한 바와 같은 종래의 압축기용 회전축은 그 회전 중심에 오일상승통로(3b)가 형성되어 있고, 그 하부에는 편심축(3a)이 형성되어 있는 바, 이 편심축(3a)의 편심력 때문에 상기 회전자(4)에 부하가 걸리고, 회전축(3)의 진동이 심하게 되는 문제점이 있었다.However, in the conventional rotating shaft for a compressor as described above, an oil rising passage 3b is formed at the center of rotation thereof, and an eccentric shaft 3a is formed at the lower portion thereof, so that the eccentric force of the eccentric shaft 3a is provided. Therefore, there is a problem that the load is applied to the rotor 4 and the vibration of the rotation shaft 3 is severe.

In the cylinder (6), the rotary shaft (3) is pushed into the rotating rotor (4) rotated under the influence of the magnetic field of the stator (2), and the eccentric shaft formed on the lower side of the rotary shaft ( The roller 5 provided in the outer peripheral surface of 3a) is provided.

상기 회전축(3)은 상기 회전자(4)의 중심에 삽입되어 회전하면서 그 내측으로 오일(13)를 공급하도록 오일 픽업부재(15)가 삽입된 오일상승통로(3b)가 형성되어 있는 바, 상기 회전축(3)의 오일상승통로(3b)는, 상기 회전축(3)의 회전 중심선(O)에서 상기 편심축의 중심선(E) 쪽으로 수평 이동시킨 위치에 형성되어 있다.The rotary shaft (3) is inserted into the center of the rotor (4) is provided with an oil lift path (3b) is inserted into the oil pickup member 15 is inserted so as to supply the oil 13 to the inside, The oil rise passage 3b of the rotation shaft 3 is formed at a position horizontally moved from the rotation center line O of the rotation shaft 3 toward the center line E of the eccentric shaft.

상기 회전축(3)의 오일상승통로(3b)는 상기 회전축(3)의 편심축(3a)을 포함한 전체의 무게 중심선(W)과 최대한 가까운 거리를 유지하도록 형성되어 있다.The oil rising passage 3b of the rotating shaft 3 is formed to maintain a distance as close as possible to the entire center of gravity line W including the eccentric shaft 3a of the rotating shaft 3.

여기서, 상기 회전축(3)의 회전 중심선(O)과 상기 편심축(3a)을 포함한 회전축(3)의 전체 무게 중심선(W)과의 거리는 R2로서, 종래의 R1보다 작다.Here, the distance between the rotation center line O of the rotation shaft 3 and the total center of gravity W of the rotation shaft 3 including the eccentric shaft 3a is R2, which is smaller than the conventional R1.

이와 같은 본 발명에 의한 압축기에서 그 작용 및 효과를 설명하면, 전원을 인가하면 고정자(2)에 자장이 형성되고, 이 형성된 자장의 영향으로 그 내측의 회전자(4)가 회전하게 되고, 동시에 상기 회전자(4)의 내측에 압입된 회전축(3)이 회전하게 된다.Referring to the operation and effects of the compressor according to the present invention, when a power is applied, a magnetic field is formed in the stator 2, and the rotor 4 inside thereof rotates under the influence of the formed magnetic field.
