Space between the crank chamber output hole 2 and the suction hole 1 is formed to be in close contact with the shaft 15 so that the gas flows only through the crank chamber output hole 2, and the pressure gas introduced through the suction hole 1 The diameter is slightly larger than the malleable shaft 15 so as to flow into the space formed between the upper housing 9 and the upper disk 12.

상기 스트리너(5)는 토출실과 연결되어 토출실로부터 냉매가스가 냉매가스 유입홀(3)로 유입되도록 원통형상의 틀 외부에 철망을 형성한다.The streamer 5 is connected to the discharge chamber to form a wire mesh outside the cylindrical frame so that the refrigerant gas flows into the refrigerant gas inlet hole 3 from the discharge chamber.

상기 스프링(7)은 볼밸브(6)와 조정스크류(8)사이에 위치하여 상기 스트리너(5)를 통해 유입된 냉매가스가 몸체(4) 내부 냉매가스유입홀(3)로 유입되는 것을 제어하는 볼밸브(6)의 상하동작을 자체 탄성력을 이용하여 가능토록 한다.The spring (7) is located between the ball valve (6) and the adjustment screw (8) is the refrigerant gas introduced through the streamer (5) is introduced into the refrigerant gas inlet hole (3) inside the body (4) The vertical motion of the ball valve 6 to be controlled is made possible using its own elastic force.

상기 조정스크류(8)는 스트리너(5) 하단부 내부에 나사결합되도록 구성되되, 내부 삽입정도는 상기 스프링(7)이 볼밸브(6)를 가압하는 힘을 사용 용도에 맞도록 삽입하고, 상기 스트리너(5)를 통해 유입되는 냉매가스가 관통되도록 홀(81)이 구성되며, 상기 홀(81)의 형상은 육각형, 사각형 및 원형 등 어떠한 형상으로 하여도 무방하다.The adjusting screw (8) is configured to be screwed into the lower end of the streamer (5), the internal insertion degree of the spring (7) to insert the force to press the ball valve (6) to suit the intended use, the The hole 81 is configured to penetrate the refrigerant gas flowing through the streamer 5, and the hole 81 may have any shape such as a hexagon, a rectangle, and a circle.

상기 상부하우징(9)과 하부하우징(10)의 결합을 위해 상부하우징(9) 하부 외주면보다 하부하우징(10) 외주면을 약간 크게 형성하며, 상부하우징(9)과 하부하우징(10)이 연결되는 부분은 납땜을 이용해 외부와의 기밀성을 유지한다.In order to couple the upper housing 9 and the lower housing 10, the outer peripheral surface of the lower housing 10 is slightly larger than the lower outer surface of the upper housing 9, and the upper housing 9 and the lower housing 10 are connected to each other. The parts are soldered to keep them airtight.

상기 다이어프램(11)은 도 4 및 도 5에 도시된 바와 같이 상기 흡입홀(1)을 통해 유입되는 압력가스의 유무에 의해 상하로 움직임에 따라 상기 다이어프램(11)의 유연성(복원력)이 떨어지는 것을 방지함은 물론 다이어프램(11)의 원활한 유연성 확보, 반복동작으로 인한 백화현상 혹은 미세한 갈라짐 현상을 방지하도록 원 중심부로부터 외곽 둘레까지 반원형태의 굴곡(11a)(11b)(11c)이 각각 형성되며, 다이어프램(11) 외곽쪽에 형성되어 있는 상기 반원형태의 굴곡(11c)은 35°이하로 제조하여 다이어프램(11)의 반복작용시 하부하우징(10)의 일측면에 접촉이 되지 않도록 함으로써 다이어프램(11) 반복 동작시 신뢰성을 높일 수 있다.As shown in FIGS. 4 and 5, the diaphragm 11 may be reduced in flexibility (restoration force) of the diaphragm 11 as it moves up and down by the presence or absence of pressure gas flowing through the suction hole 1. The semicircular bends (11a) (11b) (11c) are formed from the center of the circle to the outer periphery, respectively, to prevent the prevention, as well as to ensure smooth flexibility of the diaphragm (11), and to prevent whitening or minute cracking due to repetitive operation. The semi-circular curve 11c formed on the outer side of the diaphragm 11 is manufactured to be 35 ° or less so that the diaphragm 11 does not come into contact with one side of the lower housing 10 during the repeated action of the diaphragm 11. Reliability can be increased during repeated operation.

상기 다이어프램(11)은 반원형태의 굴곡(11a)(11b)(11c)을 각각 형성함으로써 다이어프램(11)의 반복 작용시 원 상태로 복원하는 신뢰성을 높임은 물론, 상기 흡입홀(1)을 통해 유입되는 압력가스의 유무에 의한 상하 움직임에 따라 발생되는 열화에 의해 수명이 단축되는 것을 방지하도록 열화에 강한 황동재료로 제조하는 것이 바람직하다.The diaphragm 11 forms semi-circular bends 11a, 11b, and 11c, respectively, to increase the reliability of restoring the original state when the diaphragm 11 is repeatedly operated, and through the suction hole 1. It is preferable to manufacture a brass material resistant to deterioration so as to prevent the life from being shortened by deterioration caused by the up and down movement due to the presence or absence of pressure gas.

도 3에 도시되어 있는 다이어프램(11)의 형상은 도 4에 도시된 다이어프램(11)을 상하부디스크(12)(13)와 결합 후, 코킹작업을 거친 상태를 나타낸 형상이다.The shape of the diaphragm 11 illustrated in FIG. 3 is a shape showing a state in which the diaphragm 11 illustrated in FIG. 4 has been coked with the upper and lower disks 12 and 13 and then coked.

도 6 및 도 7에 도시된 바와 같이 상하부디스크(12)(13)는 하나의 디스크를 사용하는 것으로 다이어프램(11) 위쪽에 위치시키는 상부디스크(12)와 다이어프램(11) 아래쪽에 거꾸로 하부디스크(13)를 위치시킨다.As shown in FIGS. 6 and 7, the upper and lower disks 12 and 13 use one disk, and the upper and lower disks 12 and 13 are positioned upside down on the diaphragm 11 and the lower disk upside down under the diaphragm 11. 13).

이러한 상하부디스크(12)(13)는 상기 다이어프램(11)의 중앙 부분에 형성된 굴곡(11a)(11b)과 부합되는 위치에 각각 원형에 가깝도록 돌출부위(12a)(12b)를 형성하되, 상기 상하부디스크(12)(13)가 접촉되는 부분 즉, 돌출부위(12a)(12b)는 일정면적을 두어 접촉면적을 일정하도록 함으로써 다이어프램(11)과의 긴밀성을 유지하도록 한다.The upper and lower discs 12 and 13 form protrusions 12a and 12b at positions corresponding to the bends 11a and 11b formed at the central portion of the diaphragm 11, respectively, so as to be close to a circle. The portion where the upper and lower discs 12 and 13 are in contact, that is, the protruding portions 12a and 12b, maintain a close area with the diaphragm 11 by keeping a constant contact area.

또한, 상하부디스크(12)(13)의 정중앙에 위치한 상기 돌출부위(12a)는 중심을 반원형으로 형성하여 상기 샤프트(15)와의 접촉성과 조립시 편리성을 향상시켜 작업성을 향상시켰다.In addition, the protruding portion 12a positioned at the center of the upper and lower disks 12 and 13 has a semicircular shape and has improved contactability with the shaft 15 and ease of assembly, thereby improving workability.

상기 샤프트(15)는 몸체(4) 내부 냉매가스유입홀(3) 입구에 위치한 볼밸브(6) 위치부터 상부디스크(12)까지 연결되도록 구성되어 있다. 따라서, 상기 몸체(4) 하부에 형성된 흡입홀(1)을 통해 유입되는 압력가스의 압력이 하부디스크(13) 하부에 형성된 스프링(14)의 장력보다 클 경우 다이어프램(11)과 함께 상하 부디스크(12)(13)가 아래쪽으로 이동하면, 샤프트(15)도 아래쪽으로 이동하여 볼밸브(6)가 냉매가스유입홀(3)로 유입되는 냉매가스를 차단하도록 한다.The shaft 15 is configured to connect from the position of the ball valve 6 located at the inlet of the refrigerant gas inlet hole 3 inside the body 4 to the upper disk 12. Therefore, when the pressure of the pressure gas flowing through the suction hole 1 formed in the lower portion of the body 4 is greater than the tension of the spring 14 formed in the lower disk 13, the upper and lower sub-disks together with the diaphragm 11 When 12 and 13 move downward, the shaft 15 also moves downward so that the ball valve 6 blocks the refrigerant gas flowing into the refrigerant gas inlet hole 3.

또한 상기 흡입홀(1)로부터 유입되는 가스 압력이 스프링(14)의 장력보다 클 경우 스프링(14)의 장력에 의해 상기 다이어프램(11)과 상하부디스크(12)(13)가 원위치로 복귀함과 함께 샤프트(15)는 상기 냉매가스유입홀(3)을 차단하고 있던 볼밸브(6)를 위쪽으로 밀어내는 역할을 한다.In addition, when the gas pressure flowing from the suction hole 1 is greater than the tension of the spring 14, the diaphragm 11 and the upper and lower disks 12, 13 are returned to their original positions by the tension of the spring 14. Together, the shaft 15 serves to push upward the ball valve 6 that has blocked the refrigerant gas inlet hole (3).

상기 샤프트(15)의 상하단부(16)는 볼밸브(6)와의 접촉면을 최소화하여 상기 다이어프램(11)의 동작으로 인해 볼밸브(6)의 개폐시 안정성을 유지시키고 상부디스크(12)과의 접촉부분 즉, 돌출부위(12a)와의 긴밀성을 유지시켜 다이어프램(11)의 동작을 상기 볼밸브(6)로 전달시 상부디스크(12)에 손상을 최소화하도록 원형모형으로 형성한다.The upper and lower end portions 16 of the shaft 15 minimize the contact surface with the ball valve 6 to maintain stability during opening and closing of the ball valve 6 due to the operation of the diaphragm 11 and with the upper disk 12. The contact portion, that is, maintains the tightness with the projecting portion (12a) is formed in a circular model to minimize the damage to the upper disk 12 when the operation of the diaphragm (11) to the ball valve (6).

상기와 같이 서술한 바와 같이 본 발명의 용량제어밸브의 동작을 보다 상세히 설명하면 다음과 같다.As described above, the operation of the capacity control valve of the present invention will be described in more detail as follows.

1)흡입홀(1)을 통해 유입되는 압력가스의 압력이 스프링(14)의 장력보다 클 경우1) When the pressure of the pressure gas flowing through the suction hole 1 is greater than the tension of the spring 14

먼저, 흡입홀(1)로부터 압력가스가 유입된다.First, the pressure gas flows in from the suction hole 1.

흡입홀(1)로부터 유입된 압력가스는 상부하우징(9)과 상부디스크(12) 사이에 형성된 공간으로 이동하며, 이렇게 유입된 가스의 압력에 의해 다이어프램(11)과 상하부디스크(12)(13)가 아래쪽 즉, 스프링(14)쪽으로 이동하게 된다.The pressure gas introduced from the suction hole 1 moves to the space formed between the upper housing 9 and the upper disk 12, and the diaphragm 11 and the upper and lower disks 12 and 13 are caused by the pressure of the gas introduced therein. ) Is moved downwards, ie towards the spring 14.

상기 다이어프램(11)과 상하부디스크(12)(13)가 아래쪽으로 이동함에 따라 몸체(4) 내부를 관통하고 있는 샤프트(15)가 아래쪽으로 이동하게된다.As the diaphragm 11 and the upper and lower disks 12 and 13 move downward, the shaft 15 penetrating the inside of the body 4 moves downward.

상기 샤프트(15)의 이동에 따라 스프링(7)의 탄성에 의해 스프링(7)이 볼밸브(6)를 아래쪽으로 밀쳐내어 상기 볼밸브(6)가 냉매가스유입홀(3)을 차단함으로써 스트리너(5)를 통해 토출실로부터 유입되는 냉매가스의 크랭크실내로의 유입이 차단된다.As the shaft 15 moves, the spring 7 pushes the ball valve 6 downward by the elasticity of the spring 7 so that the ball valve 6 blocks the refrigerant gas inlet hole 3. Inflow of the refrigerant gas from the discharge chamber through the nut 5 into the crank chamber is blocked.

2)흡입홀(1)을 통해 유입되는 압력가스의 압력이 스프링(14)의 장력보다 작을 경우2) When the pressure of the pressure gas flowing through the suction hole 1 is less than the tension of the spring 14

흡입홀(1)을 통해 유입된 스프링(14)의 장력보다 높은 압력가스가 줄어들거나 혹은 흡입홀(1)로부터 가스의 유입이 중단될 경우, 스프링(14)의 탄성력에 의해 아래쪽으로 이동해있던 다이어프램(11)과 상하부디스크(12)(13)가 원위치로 복원된다.When the pressure gas higher than the tension of the spring 14 introduced through the suction hole 1 is reduced or the inflow of gas from the suction hole 1 is stopped, the diaphragm moved downward by the elastic force of the spring 14. (11) and the upper and lower disks 12 and 13 are restored to their original positions.

상기 다이어프램(11)과 상하부디스크(12)(13)의 복원에 따라 상부디스크(12)와 접촉되어 있던 샤프트(15)가 위쪽으로 이동하게된다.As the diaphragm 11 and the upper and lower disks 12 and 13 are restored, the shaft 15 which has been in contact with the upper disk 12 is moved upward.

상기 샤프트(15)의 이동에 따라 냉매가스유입홀(3)을 차단하고 있던 볼밸브(6)를 위쪽으로 이동 즉, 밀어내게 된다.As the shaft 15 moves, the ball valve 6 which blocks the refrigerant gas inlet hole 3 is moved upward, that is, pushed out.

상기 볼밸브(6)가 위쪽으로 이동함에 따라 스트리너(5)와 조정스크류(8)에 형성된 홀(81)을 통해 몸체(4) 상부 공간으로 유입된 냉매가스가 냉가가스유입홀(3)을 통해 크랭크실내출력홀(2)을 통해 크랭크 실내로 유입되게 된다.As the ball valve 6 moves upward, the refrigerant gas introduced into the upper space of the body 4 through the hole 81 formed in the streamer 5 and the adjusting screw 8 is a cold gas inlet hole 3. Through the crank indoor output hole (2) is introduced into the crank room.

상술한 바와 같이 본 발명에 의한 용량제어밸브는, 스프링의 탄성을 이용하여 다이어프램과 디스크를 상하 이동시킴으로써 전기식 압력제어밸브에 비해 냉매 조절능력 성능을 획기적으로 향상시킴은 물론, 제조공정 단축 및 원가절감면에서 효율성을 극대화시키는 잇점이 있다.As described above, the capacity control valve according to the present invention uses the elasticity of the spring to move the diaphragm and the disk up and down to dramatically improve the refrigerant control capacity performance compared to the electric pressure control valve, as well as shorten the manufacturing process and reduce the cost. In terms of efficiency, there is an advantage.
