본 발명은 진공 벨로우즈 조립체 제조방법에 관한 것으로, 더욱 상세하게는 용량가변형 압축기의 용량제어밸브에 적용되는 진공 벨로우즈 조립체 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a vacuum bellows assembly, and more particularly, to a method for manufacturing a vacuum bellows assembly applied to a capacity control valve of a variable displacement compressor.

일반적으로, 벨로우즈(Bellose)는 주름형의 구조물로서 외부의 압력에 의해 팽창/수축을 수행하면서 그것과 연결된 구성요소에 힘을 가하는 구성요소이다.In general, a bellows is a corrugated structure which is a component that exerts a force on a component connected thereto while performing expansion / contraction by external pressure.

이와 같은 벨로우즈는 용량가변형 압축기의 용량제어밸브에 적용되며 도 1을 참고하여 개략적으로 설명한다.This bellows is applied to the capacity control valve of the variable displacement compressor and will be described schematically with reference to FIG.

도 1에 도시한 바와 같이, 용량가변형 압축기의 용량제어밸브(100)는, 몇 가지 연결공이 형성된 밸브하우징(110), 전자 솔레노이드(130), 상기 밸브 하우징(110)의 내부에서 이동 가능하게 설치되는 밸브체(120)를 포함하고 있다.As shown in FIG. 1, the displacement control valve 100 of the variable displacement compressor is installed to be movable inside the valve housing 110, the electromagnetic solenoid 130, and the valve housing 110 in which several connection holes are formed. The valve body 120 is included.

그리고, 상기 밸브 하우징(110)에는 밸브체(120)의 이동을 안내하기 위한 제1안내공(117)이 형성된다.In addition, a first guide hole 117 is formed in the valve housing 110 to guide the movement of the valve body 120.

특히, 상기 전자 솔레노이드(130)가 통전됨에 따라 밸브체(120)가 왕복 이동하면서 밸브하우징(110)에 형성된 제1안내공(117)을 개폐하는 구성으로 되어 있다.In particular, as the electromagnetic solenoid 130 is energized, the valve body 120 is configured to open and close the first guide hole 117 formed in the valve housing 110 while reciprocating.

상기 밸브하우징(110)에는 크랭크실의 압력(Pc)과 토출실의 압력(Pd)이 각각 작용하는 크랭크실 연결공(112)과 토출실 연결공(113)이 형성되어 있다. 그리고, 상기 토출실 연결공(113)과 크랭크실 연결공(112)은 상기 제1안내공(117)을 통해 서로 연통되는 구조로 되어 있다.The valve housing 110 has a crank chamber connecting hole 112 and a discharge chamber connecting hole 113 in which the pressure Pc of the crank chamber and the pressure Pd of the discharge chamber respectively act. The discharge chamber connecting hole 113 and the crank chamber connecting hole 112 have a structure in communication with each other through the first guide hole 117.

그리고, 상기 밸브체(120)는 턱부(121)를 경계로 하여 대경부(122)와 소경부(123)로 나뉘어져 있다.The valve body 120 is divided into a large diameter portion 122 and a small diameter portion 123 with the jaw portion 121 as a boundary.

또한, 상기 밸브체(120)의 소경부(123)의 그 끝단으로 슬리브(140)가 구비되며, 상기 슬리브(140)가 설치되는 상기 밸브하우징(110)에는 슬리브 보어(119)가 형성된다.In addition, a sleeve 140 is provided at the end of the small diameter portion 123 of the valve body 120, and a sleeve bore 119 is formed in the valve housing 110 in which the sleeve 140 is installed.

이에 따라, 상기 전자 솔레노이드(130)의 통전에 의해 밸브체(120)가 왕복운동함과 동시에, 밸브체(120)의 턱부(121)에 의해 토출실 연결공(113)과 크랭크실 연결공(112) 사이를 연결하는 제1안내공(117)의 입구가 개폐된다.Accordingly, the valve body 120 reciprocates by the energization of the electromagnetic solenoid 130, and the discharge chamber connecting hole 113 and the crank chamber connecting hole (by the jaw portion 121 of the valve body 120). The inlet of the first guide hole 117 connecting between 112 is opened and closed.

A portion of the tip of the sleeve 140 passing through the sleeve bore 119 of the valve housing 110 protrudes from the bellows accommodating part 170, and a bellows 160 is provided at the tip thereof.

상기 벨로우즈(160) 내부에는 팽창된 상태를 유지하도록 스프링(162)이 내장된다.A spring 162 is built in the bellows 160 to maintain the expanded state.

한편, 상기 벨로우즈 수용부(170)는 흡입실 압력(Ps)이 작용된다.On the other hand, the bellows receiving portion 170 is applied to the suction chamber pressure (Ps).

또한, 상기 벨로우즈(160)를 감싸도록 캡(165)이 더 구비되며, 상기 캡(165)은 상기 밸브하우징(110)과 나사결합되어 상기 캡(165)의 회전에 의해 상기 벨로우즈(160) 및 스프링(162)의 초기 설정값을 조정할 수 있게 된다.In addition, a cap 165 is further provided to surround the bellows 160, and the cap 165 is screwed with the valve housing 110 to rotate the bellows 160 by the rotation of the cap 165. The initial set value of the spring 162 can be adjusted.

이러한, 흡입압(Ps)이 작용하는 벨로우즈(160)는 축소 및 팽창하여 밸브체(120)의 이동을 보조하게 되는 것이다.This, the bellows 160, the suction pressure (Ps) acts to shrink and expand to assist the movement of the valve body (120).
