상기 밸브토출장치(17)에는 흡입머플러(20)가 설치되는데, 상기 흡입머플러(20)는 밸브토출장치(17)의 소음을 제거함과 동시에 압축기의 외부에서 전달된 작동유체를 압축실로 전달하는 역할을 한다.The suction discharging muffler 20 is installed in the valve discharging device 17. The suction muffler 20 removes the noise of the valve discharging device 17 and at the same time delivers the working fluid transferred from the outside of the compressor to the compression chamber. Do it.

구체적으로, 밸브토출장치(17)는, 도 2에 도시된 바와 같이, 압축실에서 압축된 작동유체를 토출하기 위한 토출포트(31a)가 형성된 밸브플레이트(31)와, 토출포트(31a)를 개폐하는 토출밸브(32)와, 토출밸브(32)의 동작을 제어하는 밸브스프링(33)과, 토출밸브(32)의 개폐영역을 제한하는 밸브스토퍼(34)와, 밸브스토퍼(34) 상에 설치되어 작동유체의 누출을 방지하기 위한 밸브패킹(35)과, 밸브패킹(35)을 고정하기 위한 토출머플러판(36)을 포함한다.Specifically, as shown in FIG. 2, the valve discharge device 17 includes a valve plate 31 and a discharge port 31a having a discharge port 31a for discharging the working fluid compressed in the compression chamber.

And a motor unit 11 including a stator 12 and a rotor 13 to be installed, and a compression mechanism unit 15 to be installed above the frame 10. However, the configuration of the compressor may be slightly different in the type and arrangement of the components, and the present invention can be applied to a compressor having such a different configuration.

그리고, 상기 압축기구부(15)에는 압축실로부터 작동유체를 전달하기 위한 본 발명의 주요 기술적 구성인 밸브토출장치(100)가 구비되어 있다. In addition, the compression mechanism (15) is provided with a valve discharge device 100, which is the main technical configuration of the present invention for delivering a working fluid from the compression chamber.

도 3에 도시된 바와 같이, 본 발명에 따른 압축기의 밸브토출장치(100)는 압축기구부(15)의 압축실에서 압축된 작동유체가 토출되는 토출포트(111)가 형성되며 이 토출포트(111)의 둘레에 고정홈(112)이 형성된 밸브플레이트(110)와, 상기 밸브플레이트(110)의 토출포트(111)를 개폐시키는 토출밸브(120)와, 상기 토출밸브(120)의 개폐영역을 제한하는 밸브스프링(160)과, 상기 토출밸브(120) 상에서 밸브플레이트(110)의 고정홈(112)에 결합되며 양단 테두리의 적어도 일부에는 고무탄성부(131)가 형성되어 있는 밸브스토퍼(130)와, 상기 밸브스토퍼(130) 상에 설치되며 상기 토출포트(111) 주위로 구멍(141)이 형성된 밸브패킹(140) 및, 상기 밸브패킹(140)을 개재하여 밸브스토퍼(130)의 양단과 중첩되게 배치되며 상기 토출포트(111) 주위로 구멍(151)이 형성된 토출머플러판(150)을 포함한다.As shown in Figure 3, the valve discharge device 100 of the compressor according to the present invention is formed with a discharge port 111 for discharging the working fluid compressed in the compression chamber of the compression mechanism 15, the discharge port 111 Valve plate 110 having a fixed groove 112 formed therein, a discharge valve 120 for opening and closing the discharge port 111 of the valve plate 110, and an opening / closing area of the discharge valve 120. Restricted valve spring 160 and the valve stopper 130 is coupled to the fixing groove 112 of the valve plate 110 on the discharge valve 120 and the rubber elastic portion 131 is formed on at least a portion of both edges ), A valve packing 140 formed on the valve stopper 130 and having a hole 141 around the discharge port 111, and both ends of the valve stopper 130 via the valve packing 140. And a discharge muffler plate 150 formed to overlap the discharge port 111 and having a hole 151 formed around the discharge port 111. .

특히, 본 발명의 실시예에 따르면, 상기 고무탄성부(131)가 밸브스토퍼(130)의 대략 직선형인 몸체부(132) 양단 테두리의 옆면과 상하면의 일부를 감싸는 구조로 되어 있다. 이를 위해, 인서트 사출성형과 유사하게 밸브스토퍼(130)의 양단에 고무소재를 입히거나 고무소재를 밸브스토퍼(130)의 양단에 도포하는 방식을 채택할 수 있다.In particular, according to an embodiment of the present invention, the rubber elastic portion 131 has a structure surrounding the sides and the upper and lower surfaces of the edges of both ends of the substantially straight body portion 132 of the valve stopper 130. To this end, similar to insert injection molding, a rubber material may be applied to both ends of the valve stopper 130 or a rubber material may be applied to both ends of the valve stopper 130.

더욱이, 상기 밸브스토퍼(130)의 양단 상하면을 둘러싸는 고무탄성부(131)는 동일한 폭의 띠 형태로 구성된 것이 좋다. 이와 같이 구성하면, 고무소재를 줄이면서도 결합을 위한 충분한 면적을 확보할 수 있다.In addition, the rubber elastic portion 131 surrounding the upper and lower ends of the valve stopper 130 may be configured in the form of a strip of the same width. With this configuration, it is possible to secure a sufficient area for bonding while reducing the rubber material.

물론, 도 5에 도시한 바와 같이, 고무탄성부(131)가 밸브스토퍼(130)의 양단 테두리의 옆면에만 피복되어 있어도 견고한 고정효과를 나타낼 수 있다.Of course, as shown in Figure 5, even if the rubber elastic portion 131 is coated only on the side surfaces of both edges of the valve stopper 130 can exhibit a rigid fixing effect.

한편, 밸브스토퍼(130)의 양단은 외측으로 볼록한 곡면으로 형성되어 있다. 특히, 밸브스토퍼(130)의 양단이 원호형 등의 곡면으로 형성되면 밸브스토퍼(130)의 양단이 밸브플레이트(110)의 고정홈(112)에 결합할 때 소정의 강도를 나타내면서도 견고한 결합이 가능하게 된다.On the other hand, both ends of the valve stopper 130 is formed to be curved outwardly convex. In particular, when both ends of the valve stopper 130 is formed into a curved surface such as an arc, etc. when both ends of the valve stopper 130 are coupled to the fixing groove 112 of the valve plate 110, a firm coupling is achieved while showing a predetermined strength. It becomes possible.

또한, 토출밸브(120)와 밸브스토퍼(130) 사이에는 밸브스프링(160)이 개재되어 있다.In addition, a valve spring 160 is interposed between the discharge valve 120 and the valve stopper 130.

상기 밸브스토퍼(130)와 밸브플레이트(110)의 결합은, 밸브스토퍼(130)를 고정홈(112)에 정확히 맞추고 손이나 간단한 타격 수단을 이용하여 밸브스토퍼(130)를 누름으로써 이루어진다.The valve stopper 130 and the valve plate 110 are coupled to each other by precisely fitting the valve stopper 130 to the fixing groove 112 and pressing the valve stopper 130 using a hand or a simple hitting means.

이러한 구성에 따라, 작동시에는 작동유체의 압력에 의해 토출밸브(120)와 밸브스프링(160)이 상향으로 절곡되면서 토출포트(111)를 개방하고, 이어서 밸브스토퍼(130)의 몸체부(132)의 중앙이 상향 이동함으로써 압축실에서 압축된 작동유체가 토출포트(111)를 통해 토출된다.According to this configuration, during operation, the discharge valve 120 and the valve spring 160 are bent upward by the pressure of the working fluid to open the discharge port 111, and then the body portion 132 of the valve stopper 130. ) Is moved upward, the working fluid compressed in the compression chamber is discharged through the discharge port 111.

이 경우, 밸브스토퍼(130)의 양단부에 형성된 고무탄성부(131)가 밸브플레이트(110)에 형성된 고정홈(112)에 견고하게 끼워지므로 압축기의 작동시에도 이탈되 는 경우가 없다. 더욱이, 밸브스토퍼(130)의 양단부는 밸브패킹(140)과 토출머플러판(150)에 의해 눌려서 고정되어 있기 때문에 이탈 방지가 확실하게 유지된다.In this case, since the rubber elastic portion 131 formed at both ends of the valve stopper 130 is firmly fitted into the fixing groove 112 formed in the valve plate 110, there is no case in which the compressor is released. Moreover, since both ends of the valve stopper 130 are pressed and fixed by the valve packing 140 and the discharge muffler plate 150, the separation prevention is reliably maintained.

한편, 작동유체의 토출이 완료되면 밸브스토퍼(130)와 밸브스프링(160)의 탄성복원력에 의해 토출밸브(120)가 하강하여 토출포트(111)를 폐쇄하게 된다.On the other hand, when the discharge of the working fluid is completed, the discharge valve 120 is lowered by the elastic restoring force of the valve stopper 130 and the valve spring 160 to close the discharge port 111.

즉, 2중의 탄성복원력을 가지는 토출밸브(120)를 통해 토출포트(111)를 신속하게 개폐시킬 수 있으며, 더불어 토출되는 가스의 역류를 신속하게 차단할 수 있다.That is, the discharge port 111 can be opened and closed quickly through the discharge valve 120 having the double elastic restoring force, and the reverse flow of the discharged gas can be quickly blocked.

전술한 바와 같은 구성의 본 발명에 따르면, 밸브스토퍼의 양단 테두리의 적어도 일부에 고무탄성부가 형성되어 있어 간단한 조립방법을 통해 밸브플레이트의 고정홈에 견고하게 고정될 수 있다.According to the present invention having the configuration as described above, the rubber elastic portion is formed on at least a portion of both edges of the valve stopper can be firmly fixed to the fixing groove of the valve plate through a simple assembly method.

이에 따라, 종래의 밸브스토퍼에 존재하는 날개부 등의 구조를 생략할 수 있어 재료비가 절감된다.As a result, a structure such as a wing portion existing in the conventional valve stopper can be omitted, thereby reducing the material cost.

또한, 본 발명에 따르면, 밸브스토퍼의 양단에 접촉하는 밸브패킹과 토출머플러판의 면적이 줄어들어 재료비와 자중을 줄일 수 있다.Further, according to the present invention, the area of the valve packing and the discharge muffler plate in contact with both ends of the valve stopper can be reduced, thereby reducing the material cost and the own weight.

또한, 본 발명에 따르면, 밸브스토퍼의 양단에 형성된 고무탄성부와 밸브플레이트의 고정홈 사이에 발생되는 진동과 소음이 현저하게 저감된다.Further, according to the present invention, vibration and noise generated between the rubber elastic part formed at both ends of the valve stopper and the fixing groove of the valve plate are significantly reduced.
