The reciprocating motors 20 and 20 mounted between the two reciprocating motors 20 and 20, the cylinders 30 mounted between the two reciprocating motors 20 and 20, and the reciprocating motors which are slidably inserted into the cylinders 30. Pistons (40) and (40), which are coupled to the movers (23) and (23) of the (20) and (20) to form a compression space (S), and suctions mounted on the front end surfaces of both pistons (40) and (40). Discharge valve assemblies 60 and 60 for mounting the valves 50 and 50 and the compression space S between both pistons 40 and 40 so as to be opened and closed, and the reciprocating motors 20 and 20. It includes a spring assembly (70, 70) for elastically supporting the movers (23) and (23) and the piston (40) (40) of the induction.

왕복동식 모터(20)(20)는 각각 원통형으로 형성하여 케이싱(10)에 고정하도록 외측 고정자(21)(21) 및 내측 고정자(22)(22)와, 그 외측 고정자(21)(21)와 내측 고정자(22)(22) 사이에 개재하여 좌우로 직진 왕복운동을 하는 가동자(23)(23)로 이루어져 있다.The reciprocating motors 20 and 20 each have a cylindrical shape and are fixed to the casing 10 by the outer stators 21 and 21 and the inner stators 22 and 22, and the outer stators 21 and 21. And the movable members 23 and 23 which reciprocate in a straight line from side to side through an inner stator 22 and 22.

외측 고정자(21)(21)는 도 2에 도시한 바와 같이 철편 여러 장을 묶어 고정자 묶음(21A)을 형성하고, 각 고정자 묶음(21A)의 양쪽 내측면이 서로 접하도록 지지링(21B)의 외주면에 방사상으로 적층하여 이루어져 있다.As shown in FIG. 2, the outer stator 21 and 21 bundle several pieces of iron to form a stator bundle 21A, and the inner side surfaces of each of the stator bundles 21A come into contact with each other. It is made by laminating radially on the outer circumferential surface.

가동자(23)(23)는 피스톤(40)(40)에 결합하여 외측 고정자(21)(21)와 내측 고정자(22)(22) 사이에 위치하는 마그네트 프레임(23A)(23A)과, 마그네트 프레임(23A)(23A)의 외주면에 장착하여 유도자기를 유도하는 다수 개의 마그네트(23B)(23B)로 이루어져 있다.The movers 23 and 23 are coupled to the pistons 40 and 40, and magnet frames 23A and 23A positioned between the outer stators 21 and 21 and the inner stators 22 and 22, It consists of a plurality of magnets 23B and 23B which are mounted on the outer circumferential surface of the magnet frames 23A and 23A to induce induction magnetism.

스프링 조립체(70)(70)는 마그네트 프레임(23A)(23A)에 밀착하여 피스톤(40)(40)과 함께 결합하는 스프링 지지대(71)(71)와, 스프링 지지대(71)(71)의 양 측면과 이에 대응하는 양쪽 외측 고정자(21)(21)의 일 측면에 양단이 각각 지지되는 수 개의 공진 스프링(72)(72)으로 이루어져 있다.The spring assemblies 70 and 70 are provided with the spring supports 71 and 71 which are in close contact with the magnet frames 23A and 23A and are engaged with the pistons 40 and 40 and the spring supports 71 and 71. It consists of several resonant springs 72 and 72, both ends of which are supported at both sides and at one side of both outer stators 21 and 21 corresponding thereto.

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

즉, 양쪽 왕복동식 모터(20)(20)에 전원을 인가하면, 각각의 피스톤(40)(40)이 실린더(30)의 내부에서 서로 반대방향으로 직선 왕복운동을 하고, 이와 동시에 냉매가스가 흡입관(SP)(SP)을 통해 케이싱(10)의 내부로 흡입되며, 이후 피스톤(40)(40)의 지속적인 왕복운동에 의해 냉매가스가 실린더(30)의 압축공간(S)으로 유입되어 압축되었다가 토출관(DP)을 통해 케이싱(10) 외부의 시스템으로 토출되는 일련의 과정을 반복하는 것이었다.That is, when power is applied to both reciprocating motors 20 and 20, the respective pistons 40 and 40 linearly reciprocate in opposite directions within the cylinder 30, and at the same time the refrigerant gas It is sucked into the casing 10 through the suction pipes SP and thereafter, the refrigerant gas is introduced into the compression space S of the cylinder 30 by the continuous reciprocating motion of the pistons 40 and 40 and compressed. Then, a series of processes of discharging to the system outside the casing 10 through the discharge pipe DP was repeated.

이러한 종래 대향형 왕복동식 압축기를 조립하는 과정은 대략 다음과 같다.The process of assembling such a conventional counter-reciprocating compressor is as follows.

먼저, 각 왕복동식 모터(20)(20)의 외측 고정자(21)(21)와 내측 고정자(22)(22)를 결합하여 함께 케이싱(10)에 압입하고, 그 외측 고정자(21)(21)의 일 측면과 이에 대향하는 스프링 지지대(71)(71)의 사이에 공진스프링(72)(72)을 장착하며, 스프링 지지대(71)(71)의 타 측면과 이에 대응하는 실린더(30)의 일 측면 사이에 다른 공진스프링(72)(72)을 장착하는 것이었다.First, the outer stators 21 and 21 and the inner stators 22 and 22 of each reciprocating motor 20 and 20 are combined and press-fitted into the casing 10 together, and the outer stators 21 and 21. Resonant springs 72 and 72 are mounted between one side of the spring supporter and the spring supporter 71 and 71 opposite to each other, and the other side of the spring supporter 71 and 71 and the cylinder 30 corresponding thereto. Another resonant spring 72, 72 was mounted between one side of the.

그러나, 상기와 같은 종래 왕복동식 압축기에서는, 각 왕복동식 모터(20)(20)의 외측 고정자(21)(21)를 케이싱(10)에 완전히 고정하지 않아 가동자(23)(23)와 피스톤(40)(40)의 왕복운동시 외측 고정자(21)(21)가 자력에 끌려 움직이면서 압축기의 신뢰성을 저하시킬 우려가 있었다.However, in the conventional reciprocating compressor as described above, the outer stators 21 and 21 of the respective reciprocating motors 20 and 20 are not completely fixed to the casing 10, so that the movers 23 and 23 and the piston are not. In the reciprocating motion of the 40 and 40, the outer stator 21 and 21 are attracted by the magnetic force, which may lower the reliability of the compressor.

본 발명은 상기와 같은 종래 대향형 왕복동식 압축기가 가지는 문제점을 감안하여 안출한 것으로, 왕복동식 모터의 고정자를 케이싱에 고정할 수 있는 대향형 왕복동식 압축기의 고정자 지지구조를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional counter-reciprocating compressor as described above, to provide a stator support structure of the counter-reciprocating compressor that can fix the stator of the reciprocating motor to the casing. There is this.

이에 도시한 바와 같이 본 발명의 대향형 왕복동식 압축기는, 흡입관(SP)과 토출관(DP)을 구비하고 후술할 왕복동식 모터(20)의 외측 고정자(21)를 지지하도록 좌우 양측에 각각 지지돌부(110)를 구비한 케이싱(100)과, 케이싱(100)의 내부 양측에 각각 장착하는 왕복동식 모터(20)와, 두 왕복동식 모터(20)의 사이에 장착하는 실린더(30)와, 실린더(30) 양측에 각 선단면이 마주보도록 하여 미끄러지게 삽입하고 상기한 왕복동식 모터(20)의 각 가동자(23)에 결합하는 피스톤(40)과, 양쪽 피스톤(40)의 선단면에 장착하는 흡입밸브(50)와, 양쪽 피스톤(40) 사이의 압축공간(S)을 개폐 가능하게 장착하는 토출밸브 조립체(60)와, 각 피스톤(40)의 양측에 각각 장착하여 각 피스톤(40)의 공진운동을 유도하는 공진스프링 조립체(70)들을 포함한다.As shown here, the counter-reciprocating compressor of the present invention includes a suction pipe SP and a discharge pipe DP and is supported on both left and right sides so as to support the outer stator 21 of the reciprocating motor 20 which will be described later. A casing 100 having a protrusion 110, a reciprocating motor 20 mounted on both sides of the casing 100, a cylinder 30 mounted between two reciprocating motors 20, The front end faces of the cylinders 30 are slid in such a manner that the front end faces each other, and the pistons 40 are coupled to the respective movers 23 of the reciprocating motor 20 and the front end faces of both pistons 40.

Resonance spring assemblies (70) to induce a resonant motion of the).

케이싱(100)은 원통형으로 형성하여 그 내주면 양 측에 상기한 지지돌부(110)를 각각 형성한다. 지지돌부(110)는 동일 원주상에 등간격으로 돌출하도록 케이싱(100)과 함께 일체로 성형하거나 또는 별도로 제작하여 용접 등으로후조립할 수 있다.The casing 100 is formed in a cylindrical shape to form the support protrusions 110 on both sides of the inner circumferential surface thereof. The support protrusion 110 may be integrally formed with the casing 100 so as to protrude at equal intervals on the same circumference, or separately manufactured by welding and the like.

지지돌부(110)는 외측 고정자(21)의 조립후 그 고정자(21)의 양측면이 밀착할 수 있도록 지지돌부(110) 사이의 간격이 고정자의 폭과 동일하게 형성하는 것이 바람직하다.The support protrusion 110 may be formed to have the same distance between the support protrusions 110 as the width of the stator so that both sides of the stator 21 may be in close contact after the assembly of the outer stator 21.

여기서, 외측 고정자(21)는 도 4에서와 같이 철편 여러 장을 묶어 고정자 묶음(21A)을 형성한 후 상기한 지지돌부(110)에 걸리지 않도록 케이싱(100)에 압입하므로 상기 지지돌부(110)는 외측 고정자(21)의 압입시 그 지지돌부(110)가 외측 고정자(21)의 고정자 묶음(21A) 사이로 통과할 수 있는 만큼의 폭으로 형성하는 것이 바람직하다.Here, the outer stator 21 bundles several pieces of iron pieces as shown in FIG. 4 to form the stator bundle 21A, and then presses the casing 100 so as not to be caught by the support protrusion 110. When the indentation of the outer stator 21, the support protrusion 110 is preferably formed in a width that can pass through between the stator bundle (21A) of the outer stator 21.

도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

도면중 미설명 부호인 21B는 지지링, 23A는 마그네트 프레임, 23B는 마그네트, 71은 스프링 지지대, 72는 공진스프링이다.In the figure, 21B is a support ring, 23A is a magnet frame, 23B is a magnet, 71 is a spring support, and 72 is a resonant spring.

상기와 같은 본 발명 대향형 왕복동식 압축기는 다음과 같이 조립한다.The opposite type reciprocating compressor of the present invention as described above is assembled as follows.

즉, 외측 고정자(21)와 내측 고정자(22)를 결합하여 케이싱(100)의 내부에 압입하고, 외측 고정자(21)의 일 측면에 안쪽 공진스프링(72)을 삽입한 다음 외측 고정자(21)와 내측 고정자(22) 사이에 피스톤(40)을 장착한 가동자(23)를 삽입하며, 가동자(23)의 스프링 지지대(71)를 사이에 두고 바깥쪽 공진스프링(72)을 삽입한 다음 피스톤(40)이 실린더(30)에 삽입하도록 그 실린더(30)를 케이싱(100)에 압입하여 고정한다.That is, the outer stator 21 and the inner stator 22 are combined and press-fitted into the casing 100, the inner resonance spring 72 is inserted into one side of the outer stator 21, and then the outer stator 21 is inserted into the casing 100. Insert the mover 23 equipped with the piston 40 between the and inner stator 22, insert the outer resonant spring 72 with the spring support 71 of the mover 23 therebetween. The cylinder 30 is press-fitted into the casing 100 to fix the piston 40 to the cylinder 30.

여기서, 도 4에 도시한 바와 같이 외측 고정자(21)를 케이싱(100)에 압입할때 외측 고정자(21)의 고정자 묶음(21A)들 사이로 케이싱(100)의 내주면에 구비한 지지돌부(110)가 통과하도록 한 후에 상기한 외측 고정자(21)를 돌려 그 외측 고정자(21)가 상기 지지돌부(110)에 걸려 지지되도록 한다.Here, as shown in FIG. 4, when the outer stator 21 is press-fitted into the casing 100, the support protrusion 110 provided on the inner circumferential surface of the casing 100 between the stator bundles 21A of the outer stator 21. After passing through the outer stator 21 is turned so that the outer stator 21 is caught by the support protrusion 110.

이렇게 하여, 고정자가 케이싱의 지지돌부에 걸려 피스톤의 운동방향에 대해 고정됨에 따라 압축기의 동작중에 상기한 고정자가 자력에 끌려 피스톤의 운동방향으로 움직이는 것을 미연에 방지할 수 있다.In this way, the stator is caught by the support protrusion of the casing and fixed to the direction of movement of the piston, thereby preventing the stator from being moved by the magnetic force in the direction of movement of the piston during the operation of the compressor.

본 발명에 의한 대향형 왕복동식 압축기의 고정자 지지구조는, 케이싱의 내주면에 고정자의 양측면을 밀착 고정할 수 있는 지지돌부를 형성하여 구성함으로써, 압축기의 운동중에 고정자가 가동자의 움직이는 방향으로 끌려 진동하는 것을 방지하여 압축기의 신뢰성을 높일 수 있다.The stator support structure of the opposing reciprocating compressor according to the present invention is formed by forming support protrusions on the inner circumferential surface of the casing, which can hold both sides of the stator in close contact, so that the stator is pulled and vibrated in the moving direction of the mover during the movement of the compressor.
