일반적으로 왕복동식 압축기는 피스톤이 선형으로 움직이면서 가스를 흡입 압축하는 것으로, 이러한 왕복동식 압축기는 크게 구동모터의 회전운동을 피스톤의 왕복운동으로 전환시켜 가스를 흡입 압축하는 방식과, 구동모터가 직선으로 왕복운동을 하면서 피스톤을 왕복운동시켜 가스를 흡입 압축하는 방식이 있다.In general, a reciprocating compressor suctions and compresses gas while the piston moves linearly.

There is a method of inhaling and compressing gas by reciprocating the piston while reciprocating.

A lubricant oil cylinder 61B, a first lubricant spring 61C and a second lubricant spring 61D for elastically supporting both ends of the lubricant piston 61B, and a front surface of the front frame 21 are installed in a lubricant cylinder 61A.

Lubricating oil suction pipe (6) which is placed next to and inserted into the front frame (21) for mounting 1H).

윤활유흡입관(61H)은 얇은 원형관을 '기억자'모양으로 형성하여 일측 끝단을 전방프레임(21)의 흡입관삽입구(21b)에 압입하여 고정하고 있다. 또, 윤활유흡입관(61H)의 고정단 부근에는 압입정도를 제한하도록 접철부(61b)를 형성하고 있다.Lubricating oil suction pipe (61H) is formed by forming a thin circular tube in the 'memory' shape, one end is fixed to the suction pipe insertion port (21b) of the front frame (21). Moreover, the fold | fold part 61b is formed in the vicinity of the fixed end of the lubricating oil suction pipe 61H so that a press-in degree may be limited.

도면중 미설명 부호인 21a는 실린더구멍, P는 압축공간이다.In the figure, reference numeral 21a denotes a cylinder hole, and P denotes a compression space.

상기와 같은 종래 왕복동식 압축기는 다음과 같이 동작한다.The conventional reciprocating compressor as described above operates as follows.

즉, 왕복동모터(30)에 전원을 인가하여 외측고정자(31)와 내측고정자(32) 사이에 플럭스(flux)를 형성하면, 그 외측고정자(31)와 내측고정자(32) 사이의 공극에 놓인 가동자(33)가 플럭스의 방향에 따라 움직이면서 공진스프링유니트(50)에 의해 지속적으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 왕복운동을 하면서 압축공간(P)의 체적이 변화하여 냉매가스를 압축공간(P)으로 흡입 압축하였다가 토출하는 일련의 과정을 반복한다.That is, when a flux is formed between the outer stator 31 and the inner stator 32 by applying power to the reciprocating motor 30, the gap between the outer stator 31 and the inner stator 32 lies in the gap. As the mover 33 moves in the direction of the flux, the resonant spring unit 50 continuously reciprocates, and the piston 42 reciprocates in the cylinder 41 while the compression space P The volume of is changed and a series of processes of suction and compression of the refrigerant gas into the compression space (P) is repeated.

이때, 프레임유니트(20)와 함께 진동하는 윤활유펌핑부(61)의 윤활유피스톤(61B)이 윤활유실린더(61A)의 내부에서 상대운동을 하면서 케이싱(10) 내부의 윤활유를 펌핑하고, 이 윤활유는 윤활유흡입관(61H)을 통해 윤활유시트(61F)와 윤활유커버(61G)의 윤활통로(61a)로 흡입되어 윤활유밸브(61E)를 통해 윤활유로부(62)를 통과하면서 압축유니트(40)의 미끄럼부로 공급되었다가 다시 케이싱(10)으로 회수되는 것이었다.At this time, the lubricating oil piston 61B of the lubricating oil pumping unit 61 vibrating together with the frame unit 20 pumps the lubricating oil inside the casing 10 while making a relative movement in the lubricating oil cylinder 61A. It is sucked into the lubrication passage 61a of the lubricating oil sheet 61F and the lubricating oil cover 61G through the lubricating oil suction pipe 61H, and passes through the lubricating oil passage 62 through the lubricating oil valve 61E, thereby sliding the compression unit 40. It was supplied to the negative and then returned to the casing (10).

그러나, 상기와 같은 종래 왕복동식 압축기의 윤활유 공급 장치에 있어서는, 윤활유흡입관(61H)이 적정 깊이만큼만 삽입될 수 있도록 중간에 접철부(61b)를 형 성하여 조립하는 것이나, 이는 윤활유흡입관(61H)의 구조를 복잡하게 할뿐만 아니라 이로 인해 압입공정이 난해하여 생산성이 저하되는 문제점이 있었다.However, in the lubricating oil supply device of the conventional reciprocating compressor as described above, the folding portion 61b is formed in the middle so that the lubricating oil suction pipe 61H can be inserted only by an appropriate depth, but this is the lubricating oil suction pipe 61H. In addition to complicating the structure of this, there was a problem in that the indentation process is difficult to reduce the productivity.

또, 윤활유흡입관(61H)을 압입함에 따라 압입중에 이 얇은 윤활유흡입관(61H)이 깨질 우려가 있을 뿐만 아니라 가공오차나 조립오차로 인해 윤활유가 누설되면서 압축유니트(40)에서의 윤활유부족을 초래할 우려도 있었다.In addition, as the lubricant suction pipe 61H is press-fitted, not only this thin lubricant suction pipe 61H may be broken during the press-fitting operation, but also the lubricant may leak due to machining or assembly errors, resulting in a lack of lubricant in the compression unit 40.

상기와 같은 본 발명 왕복동식 압축기의 윤활유 공급 장치는 다음과 같은 작용 효과를 갖는다.The lubricating oil supply device of the reciprocating compressor of the present invention as described above has the following effects.

즉, 왕복동모터(30)에 전원을 인가하여 외측고정자(31)와 내측고정자(32) 사이에 플럭스(flux)를 형성하면, 가동자(33)가 플럭스의 방향에 따라 움직이면서 공 진스프링(52)(53)에 의해 지속적으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 왕복운동을 하면서 냉매가스를 압축공간(P)으로 흡입 압축하였다가 토출하며, 이 과정에서 전방프레임(21)과 함께 진동하는 윤활유실린더(61A)에 의해 윤활유피스톤(61B)이 상대운동을 하면서 펌핑력을 발생시켜 케이싱(10)의 윤활유를 윤활유흡입관(61H)을 통해 흡입하였다가 윤활유밸브(61E)를 통해 윤활유로부(62)로 토출하여 실린더(41)와 피스톤(42) 사이의 미끄럼부로 공급하고, 이 윤활유는 실린더(41)와 피스톤(42) 사이를 윤활한 다음 다시 윤활유로부(62)를 통해 케이싱(10)으로 회수되는 일련의 과정을 반복한다.That is, when a flux is formed between the outer stator 31 and the inner stator 32 by applying power to the reciprocating motor 30, the mover 33 moves in the direction of the flux and the resonance spring 52 is moved. Reciprocating continuously by means of (53), and the piston 42 reciprocates in the cylinder 41 while sucking and compressing the refrigerant gas into the compression space P and discharging it. The lubricant cylinder 61B vibrates with the front frame 21 to generate a pumping force while the lubricant piston 61B moves relative to suck the lubricant oil of the casing 10 through the lubricant suction pipe 61H. Discharges to the lubricating oil path part 62 through 61E, and supplies it to the sliding part between the cylinder 41 and the piston 42, and this lubricating oil lubricates between the cylinder 41 and the piston 42, and then back to the lubricating oil. A series of processes to be recovered to the casing 10 through the unit 62 And clothing.

여기서, 압축기를 조립할 때 전방프레임(21)과 중간프레임(22) 사이에 윤활유공급유니트(60)를 함께 조립하게 되는데, 이때 복잡하고 정교한 윤활유흡입관(61H)의 수평유로부(61H-1)를 전방프레임(21)에 일체로 성형함에 따라 윤활유공급유니트(60)를 용이하게 조립할 수 있을 뿐만 아니라 윤활유흡입관(61H)의 수직유로부(61H-2)를 수평유로부(61H-1)에 압입하더라도 수평유로부(61H-1)에는 압입깊이 등에서 여유가 많아 조립을 용이하게 할 수 있다.Here, when assembling the compressor, the lubricating oil supply unit 60 is assembled together between the front frame 21 and the intermediate frame 22. At this time, the horizontal flow path portion 61H-1 of the complicated and sophisticated lubricating oil suction pipe 61H is assembled. By integrally molding the front frame 21, the lubricating oil supply unit 60 can be easily assembled, and the vertical flow passage 61H-2 of the lubricating oil suction pipe 61H is press-fitted into the horizontal flow passage 61H-1. Even if the horizontal flow path portion (61H-1) has a large margin in the press-in depth, etc., it is easy to assemble.

또, 윤활유흡입관(61H)의 수평유로부(61H-1)에 인서트 사출하여 조립하는 경우에는 이물질에 의해 윤활유가 오염되는 것을 막을 수 있을 뿐만 아니라 윤활유흡입관(61H)을 더욱 용이하게 조립할 수 있어 가공오차나 조립오차에 의해 윤활유가 누설되는 것을 막아 압축유니트(40)의 실린더(41)와 피스톤(42) 사이의 건마찰을 미연에 방지할 수 있다. In addition, when insert-injecting and assembling the horizontal flow path portion 61H-1 of the lubricating oil suction pipe 61H, the lubricating oil can be prevented from being contaminated by foreign substances, and the lubricating oil suction pipe 61H can be assembled more easily. It is possible to prevent lubricating oil from leaking due to an error or assembly error, thereby preventing dry friction between the cylinder 41 and the piston 42 of the compression unit 40.
