Description

리니어 압축기의 흡입밸브 고정장치Intake valve fixing device of linear compressor

본 발명은 리니어 압축기의 흡입밸브 고정장치에 관한 것으로, 특히 흡입밸브의 고정시 제위치로부터 틀어지는 것을 방지하는데 적합한 리니어 압축기의 흡입밸브 고정장치에 관한 것이다.The present invention relates to a suction valve fixing device of a linear compressor, and more particularly to a suction valve fixing device of a linear compressor suitable for preventing the intake valve from being displaced in place.

알려진 바와 같이, 리니어 압축기는 크랭크축을 대신하여 마그네트 및 코일로 피스톤을 직접 왕복운동시켜 냉매를 압축시키는 것으로, 그 일례가 도 1에 도시되어 있다.As is known, a linear compressor compresses a refrigerant by directly reciprocating a piston with a magnet and a coil in place of the crankshaft, an example of which is shown in FIG.

이에 도시된 바와 같이, 종래의 리니어 압축기는 소정형상을 갖는 밀폐용기(C)의 내부에 횡방향으로 설치되어 냉매를 흡입하여 압축 및 토출하는 압축기 유니트(10)와, 그 압축기 유니트(10)의 외부에 고정되어 미끄럼부에 오일을 공급하는 오일 공급수단(20)으로 구성되어 있다.As shown in the drawing, the conventional linear compressor has a compressor unit 10 installed in the transverse direction inside the sealed container C having a predetermined shape to suck, compress, and discharge the refrigerant, and the compressor unit 10. It is fixed to the outside is composed of an oil supply means 20 for supplying oil to the sliding portion.

상기 압축기 유니트(10)는 리니어 모터(11)의 고정자(11A)에 일체로 결합되는 실린더(12)와, 상기 리니어 모터(11)의 가동자(11B)에 결합됨과 아울러 실린더(12)의 미끄럼면에 밀착 삽입되어 압축실(미부호)을 형성하며 선형으로 왕복운동을 하면서 냉매를 흡입 압축 토출시키는 피스톤(13)과, 상기 실린더(12)의 선단면에 복개되어 토출실(미부호)을 형성하는 헤드커버(14)와, 상기 피스톤(13)의 선단면에 체결되는 흡입밸브(15)와, 상기 피스톤(13) 및 헤드커버(14)의 사이를 구획하여 압축실 및 토출실을 구분하는 토출밸브 조립체(16)와, 그 토출밸브 조립체(16)를 지지하는 압축코일스프링(17)을 포함하여 이루어져 있다.The compressor unit 10 is coupled to the cylinder 12 which is integrally coupled to the stator 11A of the linear motor 11, and to the mover 11B of the linear motor 11 and to the sliding of the cylinder 12. Closely inserted into the surface to form a compression chamber (unsigned) and linearly reciprocating while injecting and discharging the refrigerant to the piston 13 and the end surface of the cylinder 12 is covered with a discharge chamber (unsigned) The compression chamber and the discharge chamber are divided by partitioning between the head cover 14 to be formed, the suction valve 15 fastened to the front end surface of the piston 13, and the piston 13 and the head cover 14. It comprises a discharge valve assembly 16, and a compression coil spring 17 for supporting the discharge valve assembly (16).

여기서, 상기 피스톤(13)은 그 내부에 피스톤(13)의 운동방향과 동일하게 냉매유로(13a)가 길게 형성되어 있고, 그 냉매유로(13a)의 단부, 즉 피스톤(13)의 머리부위에는 상기 냉매유로(13a)와 연통되어 흡입밸브(15)의 개폐부(15a)에 의해 차별적으로 개폐되는 흡입구(13b)가 형성되어 있다.Here, the piston 13 has a refrigerant passage 13a long in the same direction as the movement direction of the piston 13 therein, the end of the refrigerant passage 13a, that is, at the head of the piston 13 A suction port 13b is formed in communication with the refrigerant passage 13a and differentially opened and closed by the opening / closing portion 15a of the suction valve 15.

상기 흡입밸브(15)는 그 개폐부(15a)가 피스톤(13)의 흡입구(13b)에 대향된 채로 피스톤(13)의 선단면 중앙에 고정볼트(18)로 체결되어 있다.The suction valve 15 is fastened with a fixing bolt 18 at the center of the front end face of the piston 13 with its opening and closing portion 15a facing the suction port 13b of the piston 13.

도면중 미설명 부호인 18a는 고정볼트의 나사부이다.In the figure, reference numeral 18a is a thread of the fixing bolt.

상기와 같은 리니어 압축기에서 리니어 모터(11)에 전류가 인가되면, 상기 가동자(11B)가 직선 왕복운동함에 의해 피스톤(13)이 실린더(12)내를 왕복운동하게 되고, 그 피스톤(13)이 실린더(12)내를 왕복운동함에 따라 밀폐용기(C)내로 유입된 냉매가스가 피스톤(13) 중심에 형성된 냉매유로(13a)를 통해 실린더(12)의 압축실내로 흡입되어 압축된 이후에 토출되는 과정을 반복하게 된다.When current is applied to the linear motor 11 in the linear compressor as described above, the piston 13 reciprocates in the cylinder 12 by the linear reciprocating motion of the mover 11B, and the piston 13 After reciprocating in the cylinder 12, the refrigerant gas introduced into the sealed container C is sucked into the compression chamber of the cylinder 12 through the refrigerant passage 13a formed at the center of the piston 13 and compressed. The discharge process is repeated.

즉, 상기 피스톤(13)의 흡입행정시는 그 피스톤(13)이 리니어 모터(11)의 가동자(11B)와 함께 후진을 하게 되어 피스톤(11)의 냉매유로(13a) 및 토출구(13b)로 유입되는 냉매가스가 흡입밸브(15)를 강하게 밀어내게 되고, 그 냉매에 의해 흡입밸브(15)의 개폐부(15a)는 젖혀지면서 냉매가스를 압축실로 흡입시키게 된다.That is, during the suction stroke of the piston 13, the piston 13 moves backward together with the mover 11B of the linear motor 11, so that the refrigerant passage 13a and the discharge port 13b of the piston 11 are moved. The refrigerant gas flowing into the suction valve 15 is strongly pushed in, and the opening / closing part 15a of the suction valve 15 is retracted by the refrigerant to suck the refrigerant gas into the compression chamber.

이후에, 상기 피스톤(13)의 압축행정시는 그 피스톤(13)이 전진을 하면서 압축실에 충진된 냉매가스에 의해 흡입밸브(15)의 개폐부(15a)가 밀려 피스톤(13)의 흡입구(13b)를 닫게 되는 것이었다.Subsequently, during the compression stroke of the piston 13, the opening and closing portion 15a of the suction valve 15 is pushed by the refrigerant gas filled in the compression chamber while the piston 13 moves forward, so that the suction port ( 13b).

그러나, 상기와 같은 종래 리니어 압축기에 있어서는, 상기 흡입밸브(15)를 피스톤(13)의 선단면에 고정시키기 위하여 그 피스톤(13)의 선단면 중앙에 나사홈(미부호)을 형성하고, 그 나사홈에 흡입밸브(15)의 관통공(미부호)을 일치시킨 후 고정볼트(18)의 머리부로 흡입밸브(15)를 눌러 조이면서 나사부(18a)로 피스톤(13)의 나사홈에 체결시키는 것이었으나, 이는 상기 고정볼트(18)의 체결시 발생되는 토오크에 의해 흡입밸브(15)까지 물려 돌아가면서 피스톤(13)의 토출구(13b)와 흡입밸브(15)의 개폐부(15a)가 불일치됨에 따라 냉매가스의 누출이 발생되어 압축기 효율이 저하될 우려가 있었다.However, in the conventional linear compressor as described above, in order to fix the suction valve 15 to the front end surface of the piston 13, a screw groove (unsigned) is formed in the center of the front end surface of the piston 13, and Match the through hole (unsigned) of the suction valve 15 with the screw groove, and then tighten the suction valve 15 with the head of the fixing bolt 18 and fasten it to the screw groove of the piston 13 with the screw portion 18a. However, this is caused by the torque generated when the fixing bolt 18 is fastened to the suction valve 15, the discharge port 13b of the piston 13 and the opening and closing portion 15a of the suction valve 15 is inconsistent. As a result, leakage of the refrigerant gas may occur, thereby reducing the compressor efficiency.

따라서, 본 발명은 상기와 같은 종래 리니어 압축기의 흡입밸브 고정장치가 가지는 문제점을 감안하여 안출한 것으로, 상기 흡입밸브의 고정시 그 흡입밸브가 제위치를 유지하도록 하여 압축기 효율이 저하되는 것을 미연에 방지할 수 있는 리니어 압축기의 흡입밸브 고정장치를 제공하려는데 본 발명의 목적이 있다.Accordingly, the present invention has been made in view of the problems of the conventional suction valve fixing device of the linear compressor, it is not known that the compressor efficiency is reduced by maintaining the suction valve in place when the suction valve is fixed. It is an object of the present invention to provide a suction valve fixing device of a linear compressor that can be prevented.

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 122는 개폐부이다.Reference numeral 122 in the figure is an opening and closing portion.

상기와 같은 본 발명에 의한 흡입밸브의 고정장치는 다음과 같이 조립된다.The fixing device of the suction valve according to the present invention as described above is assembled as follows.

즉, 상기 피스톤(110)의 리벳구멍(113)에 흡입밸브(120)의 체결구멍(121)을 일치시킨 다음에, 그 체결구멍(121)측에서 리벳구멍(113)측으로 임의의 리벳몸통(131)을 삽입시키고 나서, 상기 피스톤의 내측에서 리벳몸통(131)의 단부를 지그 등으로 눌러 확장되도록 하여 흡입밸브(120)를 고정시킨다.That is, the rivet hole 113 of the piston 110 is matched with the fastening hole 121 of the suction valve 120, and then an arbitrary rivet body (from the fastening hole 121 side to the rivet hole 113 side) After inserting 131, the inlet valve 120 is fixed by pressing the end of the rivet body 131 with a jig or the like inside the piston to expand it.

이때, 상기 리벳머리(132)의 직경이 체결구멍(121)의 직경보다 크게 형성되어 흡입밸브(120)가 리벳머리(132)에 눌려 피스톤(110)의 선단면에 고정된다.At this time, the diameter of the rivet head 132 is formed larger than the diameter of the fastening hole 121, the suction valve 120 is pressed by the rivet head 132 is fixed to the front end surface of the piston (110).

이렇게 하여, 상기 흡입밸브(120)를 피스톤(110)의 선단면에 고정시키는 과정에서 별도의 토오크가 흡입밸브(120)에 가해지지 않게 되어 밸브(120)의 틀어짐이 미연에 방지될 수 있는 것은 물론, 상기 리벳몸통(131)의 외주면 및 그 리벳몸통(131)이 삽입되는 체결구멍(121)과 리벳구멍(113)에는 각각 걸림면(131a)과 걸림평면(121a,113a)이 형성되어 서로 형합되므로, 상기한 리벳체결 이후에 흡입밸브(120) 및 리벳(130)이 원주방향으로 돌아가지 않게 되어 흡입밸브(120)의 틀어짐이 방지되는 것이다.In this way, in the process of fixing the intake valve 120 to the front end surface of the piston 110, a separate torque is not applied to the intake valve 120, so that the distortion of the valve 120 can be prevented in advance. Of course, engaging surfaces 131a and engaging surfaces 121a and 113a are formed in the outer circumferential surface of the rivet body 131 and the fastening hole 121 and the rivet hole 113 into which the rivet body 131 is inserted, respectively. Since it is combined, the suction valve 120 and the rivet 130 do not rotate in the circumferential direction after the rivet fastening described above is prevented from twisting the suction valve 120.
