Description

압축기용 밸브 어셈블리Valve assembly for compressor

본 고안은 밸브 어셈블리에 관한 것으로서, 보다 상세하게는 압축기용 밸브 어셈블리에 관한 것이다.The present invention relates to a valve assembly, and more particularly to a valve assembly for a compressor.

일반적으로, 압축기는 유체를 가압하여 유체의 압력, 온도 등을 소정 목적에 적합하도록 변경시키는 장치인 바, 이는 동작 형태에 따라 사판식, 피스톤식 등으로 구분된다.In general, the compressor is a device that pressurizes the fluid to change the pressure, temperature, and the like of the fluid to suit a predetermined purpose.

상기한 피스톤식 압축기는 도 2에 도시된 바와 같이 하우징(50)과, 상기한 하우징(50) 내부에 고정 설치된 스테이터(51)와, 상기한 스테이터(51)에 삽입되어 회전되도록 설치된 로우터(52)와, 상기한 로우터(52)의 축(53)에 연결 설치된 크랭크 축(54)과, 상기 크랭크 축(54)에 컨넥팅 로드(55)로 연결됨과 아울러 실린더 블록(56)의 보어(57)에 슬라이딩 가능하게 결합된 피스톤(58)과, 상기한 실린더 블록(56)과 밸브 어셈블리(59)를 개재한 상태로 결합된 실린더 헤드(60)로 구성되어 있다.As shown in FIG. 2, the piston-type compressor includes a housing 50, a stator 51 fixedly installed inside the housing 50, and a rotor 52 installed to rotate by being inserted into the stator 51. ), A crank shaft 54 connected to the shaft 53 of the rotor 52, and a bore 57 of the cylinder block 56 connected to the crank shaft 54 by a connecting rod 55. Piston 58 is slidably coupled to the (), and the cylinder head 60 coupled via the cylinder block 56 and the valve assembly (59).

즉, 로우터(52)가 회전함에 따라 크랭크 축(54)이 회전되고, 이와 결합된 피스톤(58)이 보어(57)를 왕복 운동하면서 외부 공기를 흡입 및 압축하면서 배출하게 되는 것이다.That is, as the rotor 52 rotates, the crankshaft 54 is rotated, and the piston 58 coupled thereto is discharged while inhaling and compressing outside air while reciprocating the bore 57.

여기서, 상기한 밸브 어셈블리(59)는 유체의 흡입 및 배출을 제어하게 되는 바, 이는 도 3과 도 4에 도시된 바와 같이 실린더 블록(56)과 밀착됨과 아울러 흡입 밸브(61)가 형성된 흡입 플레이트(62)와, 상기한 흡입 플레이트(62)에 밀착됨과 아울러 흡입공, 배출공(63, 64)이 형성되어 있는 밸브 플레이트(65)와, 상기한 밸브 플레이트(65)에 순차적으로 결합된 배출 밸브(66), 스토퍼(67), 키퍼 플레이트(68)와, 상기한 밸브 플레이트(65)의 상면에 결합되는 실린더 헤드(60)로 구성되어 있다.Here, the valve assembly 59 controls the suction and discharge of the fluid, which is in close contact with the cylinder block 56 as shown in FIGS. 3 and 4, and the suction plate on which the suction valve 61 is formed. (62), the valve plate 65 which is in close contact with the suction plate 62 and in which the suction holes and the discharge holes 63 and 64 are formed, and the discharge plate sequentially coupled to the valve plate 65. It consists of the valve 66, the stopper 67, the keeper plate 68, and the cylinder head 60 couple | bonded with the upper surface of the valve plate 65 mentioned above.

물론, 상기한 흡입공(63)은 흡입 플레이트(62)에 형성된 흡입 밸브(61)에 의해 간헐 제한되고, 배출공(64)은 상기한 배출 밸브(66)에 의해 간헐 제한된다.Of course, the suction hole 63 is intermittently limited by the suction valve 61 formed in the suction plate 62, and the discharge hole 64 is intermittently limited by the discharge valve 66 described above.

즉, 피스톤(58)의 왕복 운동 시 흡입 행정에서는 외부의 공기가 흡입되는 바, 피스톤(58)이 도면에서 좌측으로 이동하게 되면 흡입 밸브(61)가 당겨지면서 흡입공(63)과 이격되고, 이를 통해 외부 공기가 흡입된다.That is, in the suction stroke during the reciprocating motion of the piston 58, the outside air is sucked in. When the piston 58 moves to the left in the drawing, the suction valve 61 is pulled and spaced apart from the suction hole 63. This allows the outside air to be sucked in.

흡입 후 다시 피스톤(58)이 우측으로 이동하게 되면 보어(57) 내부의 공기가 압축되는 바, 소정 압력이 되면 상기한 공기가 배출공(64)을 통해 배출 밸브(66)를 밀어 내고 외부로 배출된다.When the piston 58 is moved to the right side again after the suction, the air inside the bore 57 is compressed, and when the pressure reaches a predetermined pressure, the air pushes the discharge valve 66 through the discharge hole 64 to the outside. Discharged.

이때, 상기한 배출 밸브(66)의 열림 정도는 상기한 스토퍼(67)가 배출 밸브(66)에 의해 상향되면서 키퍼 플레이트(68)에 접촉되는 것에 의해 제한됨으로써 배출 밸브(66)의 과다한 열림 및 이로 인한 밸브의 변형을 방지하게 된다.At this time, the opening degree of the discharge valve 66 is limited by being contacted with the keeper plate 68 while the stopper 67 is upwardly lifted by the discharge valve 66 and excessive opening of the discharge valve 66 and This prevents the deformation of the valve.

그러나, 상기한 바와 같이 직선상인 스토퍼를 배출 밸브와 키퍼 플레이트의 사이에 개재시켜 배출 밸브를 제어하게 되면 상기한 배출 밸브의 개방 동작에 의해 스토퍼가 압박됨과 아울러 종단 부분이 구부러지게 됨으로써 배출 밸브의 동작이 부정확하게 되는 문제점이 있다.However, when the discharge valve is controlled by interposing a straight stopper between the discharge valve and the keeper plate as described above, the stopper is pressed by the opening operation of the discharge valve and the end portion is bent to operate the discharge valve. There is a problem of this inaccuracy.

또한, 상기한 스토퍼와 배출 밸브가 구부러진 상태에서 접촉하게 됨으로써 소음이 발생되는 문제점이 있다.In addition, there is a problem that the noise is generated by contacting the stopper and the discharge valve in a bent state.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 압축기의 배출 밸브 동작 시 소음 발생 및 스토퍼와 밸브 파손을 방지할 수 있는 압축기용 밸브 어셈블리를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, to provide a valve assembly for a compressor that can prevent the generation of noise and breakage of the stopper and the valve during operation of the discharge valve of the compressor.

상기한 목적을 실현하기 위하여 본 발명은 밸브 플레이트에 배출 밸브와 스토퍼와 키퍼 플레이트를 순차 적층하여 구성한 압축기용 밸브 어셈블리에 있어서, 상기한 배출 밸브의 단부가 스토퍼와 접촉되는 위치에서 키퍼 플레이트와 면접촉하도록 스토퍼에 형성된 굽힘부를 포함함을 특징으로 한다.In order to achieve the above object, the present invention provides a compressor valve assembly comprising a discharge valve, a stopper, and a keeper plate sequentially stacked on a valve plate, wherein the end of the discharge valve is in surface contact with the keeper plate at a position in contact with the stopper. It characterized in that it comprises a bent portion formed in the stopper.

1 : 굽힘부66 : 배출 밸브1: bend 66: discharge valve

67 : 스토퍼68 : 키퍼 플레이트67: stopper 68: keeper plate

도 1은 본 발명에 따른 압축기용 밸브 어셈블리를 도시한 조립 단면도로서, 배출 밸브(66)의 최대 개방 시 스토퍼(67)의 종단이 키퍼 플레이트(68)와 면접촉하도록 스토퍼(67)에 굽힘부(1)가 형성되어 있다.1 is an assembly cross-sectional view showing a valve assembly for a compressor according to the present invention, the bent portion of the stopper 67 so that the end of the stopper 67 in surface contact with the keeper plate 68 at the maximum opening of the discharge valve 66 (1) is formed.

즉, 배출 밸브(66)가 스토퍼(67)를 밀어 올려 키퍼 플레이트(68)와 배출 밸브(66)가 밀착될 때 종단 부분에서 키퍼 플레이트(68)와 면접촉됨으로써 배출 밸브(66)의 압력에 의해 스토퍼(67)가 구부러지지 않게 되는 것이다.That is, when the discharge valve 66 pushes up the stopper 67 and the keeper plate 68 and the discharge valve 66 are in close contact, the discharge valve 66 is in surface contact with the keeper plate 68 at the end portion thereof, and thus the pressure of the discharge valve 66 is reduced. This stops the stopper 67 from bending.

물론, 상기한 굽힘부(1)의 형성 위치는 배출 밸브(66)의 종단이 스토퍼(67)와 접촉되는 부분이 된다.Of course, the formation position of the said bent part 1 becomes a part in which the end of the discharge valve 66 is contacted with the stopper 67.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 압축기의 동작과 동시에 크랭크 축(54)이 회전되면서 이와 컨넥팅 로드(55)로 연결된 피스톤(58)이 보어(57) 내부에서 왕복 운동하게 된다.Referring to the operation and effect of the present invention as described above, as the crank shaft 54 rotates at the same time as the operation of the compressor, the piston 58 connected to the connecting rod 55 reciprocates in the bore 57.

피스톤(58)이 왕복 운동하게 되면 외부 공기의 흡입 및 압축이 이루어지게 되는 바, 피스톤(58)의 좌측 이동 시 흡입 밸브(61)가 부압에 의해 당겨지면서 흡입공(63)이 개방되고, 이를 통해 외부 공기가 흡입된다.When the piston 58 reciprocates, the suction and compression of the outside air is made. When the piston 58 is moved to the left, the suction valve 61 is pulled by the negative pressure to open the suction hole 63. Through the outside air is sucked in.

외부 공기가 흡입된 후 피스톤(58)이 우측 이동하게 되면 공기가 압축되면서 소정 압력이 되면 배출 밸브(64)를 밀어 올리게 된다.When the piston 58 is moved to the right after the outside air is sucked, the air is compressed and the discharge valve 64 is pushed up when the predetermined pressure is reached.

이때, 상기한 배출 밸브(64)가 개방되면 이를 지지하고 있는 스토퍼(67)가 연동하게 되는 바, 상기한 스토퍼(67)의 굽힘부(1)가 키퍼 플레이트(68)에 접촉하게 되면 스토퍼(67) 및 배출 밸브(66)가 정지하게 된다.At this time, when the discharge valve 64 is opened, the stopper 67 supporting the interlock is interlocked. When the bent portion 1 of the stopper 67 comes into contact with the keeper plate 68, the stopper ( 67 and the discharge valve 66 is stopped.

여기서, 상기한 스토퍼(67)와 키퍼 플레이트(68)의 접촉 시 배출 밸브(66)가 압력을 가해도 굽힘부(1)와 키퍼 플레이트(68)가 면접촉하고 있는 상태가 되기 때문에 스토퍼(66)가 변형되지 않게 된다.Here, even when the discharge valve 66 exerts pressure upon contacting the stopper 67 and the keeper plate 68, the bent portion 1 and the keeper plate 68 are brought into surface contact with the stopper 66. ) Is not deformed.

또한, 상기한 스토퍼(67)의 형상이 변형되지 않게 됨으로써 종래와 같이 배출 밸브(66)와 스토퍼(67)의 접촉에서 발생되는 소음이 방지됨과 아울러 배출 밸브(66)의 열림 정도를 정밀하게 제어할 수 있게 됨으로써 압축기의 성능에 신뢰성이 향상되는 것이다.In addition, since the shape of the stopper 67 is not deformed, noise generated by the contact between the discharge valve 66 and the stopper 67 is prevented as in the prior art, and the opening degree of the discharge valve 66 is precisely controlled. By doing so, the reliability of the compressor is improved.

이상과 같이 본 발명은 스토퍼에 키퍼 플레이트와 면접촉할 수 있도록 굽힘부를 형성함으로써 스토퍼의 파손 및 소음을 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention has an advantage of preventing breakage and noise of the stopper by forming a bent part in surface contact with the keeper plate.
