Description
본 발명은 왕복동형 압축기에 관한 것으로서, 더욱 상세하게는 밸브플레이트의 구조를 개선하여 토출밸브의 작동이 원활한 왕복동형 압축기에 관한 것이다.The present invention relates to a reciprocating compressor, and more particularly, to a reciprocating compressor having an improved valve plate structure and smooth operation of a discharge valve.
일반적으로 왕복동형 압축기는 회전축의 편심회전운동을 피스톤의 왕복직선운동으로 전환시켜 실린더내의 유체를 압축하는 장치이다.In general, the reciprocating compressor is a device for compressing the fluid in the cylinder by converting the eccentric rotation of the rotary shaft to the reciprocating linear movement of the piston.
이러한 왕복동형 압축기의 압축부는 도 1에 도시한 바와 같이, 밀폐용기(1)의 하부에 마련되는데, 압축부(10)는 압축실(11a)을 형성하는 실린더와(11), 피스톤(12)을 구비한다. 또한, 실린더(11) 단부에는 외부와 연통된 흡입실(13a)과 토출실(13b)이 형성된 실린더헤드(13)가 설치되고, 실린더(11)와 실린더헤드(13)사이에는 흡입실(13a)과 토출실(13b)이 각각 압축실(11a)에 연통되도록 흡입공(20a)과 토출공(20b)이 형성된 밸브플레이트(20)가 개재된다. 그리고, 밸브플레이트(20)에는 흡입공(20a)과 토출공(20b)을 각각 선택적으로 개폐하는 흡입밸브(14)와 토출밸브(15)가 설치되고, 밀폐용기(1) 하부에는 피스톤(12) 등이 원활하게 작동되도록 오일이 저장된다.As shown in FIG. 1, the compression unit of the reciprocating compressor is provided under the sealed container 1, and the compression unit 10 includes a cylinder 11 and a piston 12 forming the compression chamber 11a. It is provided. In addition, a cylinder head 13 having a suction chamber 13a and a discharge chamber 13b communicating with the outside is provided at an end of the cylinder 11, and a suction chamber 13a is provided between the cylinder 11 and the cylinder head 13. ) And the valve plate 20 in which the suction hole 20a and the discharge hole 20b are formed so that the discharge chamber 13b may communicate with the compression chamber 11a, respectively. In addition, the valve plate 20 is provided with a suction valve 14 and a discharge valve 15 for selectively opening and closing the suction hole 20a and the discharge hole 20b, respectively, and a piston 12 below the sealed container 1. ) Oil is stored to keep the lights running smoothly.
한편, 실린더헤드(13)와 마주보는 밸브플레이트(20)의 일면에 설치된 토출밸브(15)는 도 2에 도시한 바와 같이, 얇은 금속판으로, 압축실(11a)의 압축된 유체의 압력에 의해 토출공(20b)을 개방시킨다. 그리고, 토출공(20b) 둘레에는 토출공(20b)이 닫혔을 때, 토출밸브(15)의 일측과 접하여 토출공(20b)이 밀폐되도록 토출밸브(15)를 향해 소정높이로 돌출된 접촉부(21)가 형성된다. 이 접촉부(21)는 토출밸브(15)와 접하는 접촉면(21a)이 평평하게 이루어져 토출밸브(15)가 닫히면 밀착된다.On the other hand, the discharge valve 15 provided on one surface of the valve plate 20 facing the cylinder head 13 is a thin metal plate, as shown in Figure 2, by the pressure of the compressed fluid in the compression chamber 11a The discharge hole 20b is opened. When the discharge hole 20b is closed around the discharge hole 20b, the contact portion protrudes toward the discharge valve 15 at a predetermined height so as to contact one side of the discharge valve 15 to seal the discharge hole 20b ( 21) is formed. The contact portion 21 is in close contact with the discharge valve 15 when the contact surface 21a in contact with the discharge valve 15 is flat.
그러나, 종래의 왕복동형 압축기에서 접촉부에 존재하는 오일로 인하여 토출공을 개방시키는 토출밸브의 작동이 원활하지 못한 문제가 발생한다. 다시 설명하면, 피스톤의 윤활을 위하여 압축부로 소정량 유입된 오일중 접촉부의 접촉면에 존재하는 오일의 점성 때문에 접촉부에 밀착되어 있다가 실린더내의 압축된 유체의 압력으로 토출밸브가 접촉면으로부터 이격됨에 있어 어려움이 따른다. 이렇게 토출밸브의 개방이 원활하지 못하게 되면 압축유체가 충분히 토출되지 못하여 압축유체의 토출량이 감소됨으로써, 냉동사이클의 성능을 저하시키게 되는 문제가 발생하게 된다.However, in the conventional reciprocating compressor, there is a problem in that the operation of the discharge valve for opening the discharge hole is not smooth due to the oil present in the contact portion. In other words, due to the viscosity of the oil present on the contact surface of the contact portion of the oil flowed into the compression portion for lubrication of the piston, it is difficult to separate the discharge valve from the contact surface by the pressure of the compressed fluid in the cylinder. Follow. If the discharge valve is not opened smoothly, the compressed fluid is not sufficiently discharged, and the discharge amount of the compressed fluid is reduced, thereby lowering the performance of the refrigeration cycle.
또한, 흡입공을 통해 유체가 실린더 내로 유입되면서 발생하는 압력으로 열렸던 토출밸브가 닫히는데, 강도높은 금속재질로 이루어진 토출밸브가 닫히면서 평평한 접촉면과의 충돌로 인하여 소음을 유발시키는 문제가 발생한다.In addition, the discharge valve opened by the pressure generated as the fluid flows into the cylinder through the suction hole is closed, the discharge valve made of a high-strength metal is closed, causing problems due to the collision with the flat contact surface.
본 발명의 목적은 토출밸브와 접촉하는 토출공 둘레의 접촉부에 홈을 형성하여 토출밸브의 개폐가 원활한 왕복동형 압축기를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a reciprocating compressor having a smooth opening and closing of a discharge valve by forming a groove in a contact portion around a discharge hole in contact with the discharge valve.
또한, 본 발명의 또다른 목적은 토출밸브가 닫히면서 접촉부와 충돌시 발생하는 소음을 저감시키는 왕복동형 압축기를 제공하는데 있다.In addition, another object of the present invention is to provide a reciprocating compressor which reduces the noise generated when the discharge valve is closed and collides with the contact portion.

이하에서는 첨부도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.
본 발명에 따른 왕복동형 압축기는 도 3에 도시한 바와 같이, 밀폐용기(100)의 내부에 유체의 압축행정이 행해지는 압축부(120)와, 압축부(120)가 작동되도록 동력을 발생하는 구동부(110)가 마련된다. 우선, 압축부(120)는 그 내부에 압축실(121a)이 형성된 실린더(121), 실린더(121)에 삽입되어 직선왕복운동함으로써, 유체를 흡입, 압축, 토출시키는 피스톤(122)을 구비한다. 그리고, 실린더(121)의 단부에는 그 내부에 흡입실(123a)과 토출실(123b)이 형성된 실린더헤드(123)가 설치되며, 실린더(121)와 실린더헤드(123)사이에는 압축실(121a)이 흡입실(123a)과 토출실(123b)로 각각 연통되도록 흡입공(131)과 토출공(132)이 형성된 밸브플레이트(130)가 개재된다.As shown in FIG. 3, the reciprocating compressor according to the present invention generates power so that the compression unit 120 and the compression unit 120 are operated to compress the fluid within the sealed container 100. The driver 110 is provided. First, the compression unit 120 includes a cylinder 121 having a compression chamber 121a formed therein, and a piston 122 that is inserted into the cylinder 121 and linearly reciprocates to suck, compress, and discharge fluid. . In addition, a cylinder head 123 having a suction chamber 123a and a discharge chamber 123b formed therein is installed at an end of the cylinder 121, and a compression chamber 121a is disposed between the cylinder 121 and the cylinder head 123. The valve plate 130 having the suction hole 131 and the discharge hole 132 is interposed so that the tube communicates with the suction chamber 123a and the discharge chamber 123b, respectively.
이와 같이 구성된 압축부(120)에서 압축행정이 행해지도록 동력을 발생하는 구동부(110)는 밀폐용기(100) 내부에 고정된 고정자(111), 고정자(111)내에 설치되어 고정자(111)와 전자기적으로 상호작용하는 회전자(112)를 구비한다. 그리고, 회전자 중심에 결합되어 회전자(112)와 함께 회전하도록 회전축(113)이 마련되고, 회전축(113)의 하부에는 피스톤이(122) 실린더(121)내를 직선운동하도록 편심부(114)가 설치된다. 이러한 편심부(114)의 동작은 그 일단부는 편심부(114)에, 그 타단부는 피스톤(122)에 결합된 커넥팅로드(115)에 의해 피스톤(122)에 전달된다. 또한, 밀폐용기(100)의 하부에는 구동부(110), 피스톤(122) 등의 운동이 원활하도록 윤활시키는 오일이 저장된다.The driving unit 110 generating power so that the compression stroke is performed in the compression unit 120 configured as described above is installed in the stator 111 and the stator 111 fixed inside the hermetic container 100, and the stator 111 and the electrons. It has a rotor 112 that miraculously interacts. Then, the rotating shaft 113 is coupled to the center of the rotor to rotate together with the rotor 112, the lower portion of the rotating shaft 113, the piston 122, the eccentric portion 114 to linearly move in the cylinder 121 ) Is installed. The operation of the eccentric portion 114 is transmitted to the piston 122 by the connecting rod 115, one end of which is connected to the eccentric portion 114, and the other end thereof. In addition, the lower portion of the sealed container 100 is stored oil for lubricating the movement of the drive unit 110, the piston 122 and the like smoothly.
이러한 왕복동형 압축기는 구동부(110)에 전원이 인가되면 회전자(112)와 함께 회전축(113)이 회전되고, 회전축(113)의 회전으로 편심부(114)가 편심회전된다. 이 편심부(114)에 의해 피스톤(122)이 실린더(121)내를 왕복직전운동하게 되며, 피스톤(122)의 후진에 의해 유체가 실린더(121)내로 유입된다. 그리고, 피스톤(122)의 전진에 의하여 유체가 압축되다가 소정압력이상이 되면 토출공(132)이 개방되면서 압축된 유체가 토출된다.In the reciprocating compressor, when power is applied to the driving unit 110, the rotating shaft 113 is rotated together with the rotor 112, and the eccentric portion 114 is eccentrically rotated by the rotation of the rotating shaft 113. The eccentric portion 114 causes the piston 122 to move immediately before and after the cylinder 121 reciprocates, and fluid is introduced into the cylinder 121 by the reverse of the piston 122. When the fluid is compressed by the advancement of the piston 122 and the pressure is greater than or equal to a predetermined pressure, the discharge hole 132 is opened and the compressed fluid is discharged.
이와 같이 동작되는 왕복동형 압축기의 밸브플레이트(130)에는 흡입공(131)과 토출공(132)을 통한 유체의 유출입을 조절하도록 흡입밸브(124)와 토출밸브(125)가 설치되고, 이 가운데 토출밸브(125)가 닫혔을 때, 도 4에 도시된 바와 같이, 토출밸브(125)의 일단부가 그에 형성된 접촉면(141)에 밀착되도록 토출공(132) 둘레에 돌출설치된 접촉부(140)가 마련된다. 이는 도 4와 도 5를 함께 참조하면서 설명한다.In the valve plate 130 of the reciprocating compressor operated as described above, a suction valve 124 and a discharge valve 125 are installed to control the inflow and outflow of fluid through the suction hole 131 and the discharge hole 132, among which When the discharge valve 125 is closed, as shown in FIG. 4, a contact portion 140 protruding around the discharge hole 132 is provided such that one end of the discharge valve 125 is in close contact with the contact surface 141 formed thereon. do. This will be described with reference to FIGS. 4 and 5 together.
이에 도시한 바와 같이, 우선, 토출밸브(125)는 얇은 금속의 판상으로, 일단부가 접촉부(140)에 선택적으로 밀착되면서 토출공(132)을 개폐시키고, 타단부는 밸브플레이트(130)의 일측에 고정된다. 이러한 토출밸브(125)가 토출공(132)을 닫았을 때, 토출공(132)이 밀폐될 수 있도록 돌출형성된 접촉부(140)는 토출밸브(125)와의 접촉면(141)이 평평하게 이루어진다.As shown in the drawing, first, the discharge valve 125 is a thin metal plate, and one end of the discharge valve 132 is opened and closed close to the contact portion 140, and the other end is one side of the valve plate 130. Is fixed to. When the discharge valve 125 closes the discharge hole 132, the contact portion 140 protrudingly formed so that the discharge hole 132 may be closed may have a flat contact surface 141 with the discharge valve 125.
한편, 접촉부(140)로 부터 토출밸브(125)가 이격되면서 토출공(132)을 개방시킬 때, 토출밸브(125)의 동작이 원활하도록 접촉부(140)에는 홈(142)이 형성된다. 이 홈(142)은 피스톤(122)의 윤활을 위해 압축부(120)로 유입된 오일의 점성에 의해 접촉부(140)로부터 토출밸브(125)가 이격되는 어려움을 방지하게 된다.On the other hand, when opening the discharge hole 132 while the discharge valve 125 is spaced from the contact portion 140, a groove 142 is formed in the contact portion 140 to facilitate the operation of the discharge valve 125. The groove 142 is to prevent the difficulty of the discharge valve 125 is separated from the contact portion 140 by the viscosity of the oil introduced into the compression portion 120 for lubrication of the piston (122).
이 홈(142)은 접촉부(140)의 접촉면(141)에 토출공(131)의 원주방향을 따라 형성되어 토출밸브(125)를 향해 개방된다. 이 홈(142)에 의해 토출밸브(125)의 개방시 오일의 점성에 의한 장애가 감소되고, 토출밸브(125)가 닫히는 과정에서 판상의 금속재질인 토출밸브(125)가 접촉면(141)에 충돌될 때는 홈(142)에 고여있는 오일에 의해 충돌소음을 저감시키게 된다.The groove 142 is formed along the circumferential direction of the discharge hole 131 on the contact surface 141 of the contact portion 140 and opens toward the discharge valve 125. The groove 142 reduces the obstacle due to the viscosity of the oil when the discharge valve 125 is opened, and the discharge valve 125, which is a plate-shaped metal material, collides with the contact surface 141 while the discharge valve 125 is closed. When the collision noise is reduced by the oil accumulated in the groove 142.
도 6은 본 발명에 따른 왕복동형 압축기의 타실시예로, 토출공(132)을 밀폐시키면서 홈(140')의 접촉면적을 넓혀 효과를 증가시킬 수 있다. 이 홈(140')은 토출공(132)의 원주방향을 따라 형성된 제 1홈(141'a)과, 제 1홈(141'a)에서 반경방향으로 바깥쪽을 향해 연장된 제 2홈(142'b)으로 구성된다. 이 때, 토출공(132) 둘레에는 접촉부(140)의 소정부분이 존재하기 때문에 토출밸브(125)가 닫혔을 때는 유체가 유출되지 않으며, 토출밸브(125)가 열리는 과정에서는 홈(142')에 의해 원활한 개방동작이 이루어진다. 또한, 이 홈(142')에 고여있는 오일에 의해 토출밸브(125)가 닫히는 과정에서도 충돌소음을 저감시키게 된다.Figure 6 is another embodiment of the reciprocating compressor according to the present invention, it is possible to increase the effect by widening the contact area of the groove 140 'while closing the discharge hole (132). The groove 140 'includes a first groove 141'a formed along the circumferential direction of the discharge hole 132 and a second groove extending radially outward from the first groove 141'a. 142'b). At this time, since a predetermined portion of the contact portion 140 exists around the discharge hole 132, the fluid does not flow out when the discharge valve 125 is closed, the groove 142 'in the process of opening the discharge valve 125 The smooth opening operation is achieved by. In addition, collision noise is also reduced in the process of closing the discharge valve 125 by the oil accumulated in the groove 142 '.
본 발명에 따른 홈의 형상은 이에 국한되지 않고, 유체가 유출되지 않는 범위내에서 여러 가지 형상으로 형성시킬 수 있다.The shape of the groove according to the present invention is not limited thereto, and may be formed in various shapes within the range in which the fluid does not flow out.
본 발명에 따른 왕복동형 압축기에서 토출밸브가 밀착되도록 토출공둘레에 설치된 접촉부에 홈이 형성된다.In the reciprocating compressor according to the present invention, a groove is formed in the contact portion provided in the discharge hole so that the discharge valve is in close contact.
따라서, 접촉부의 접촉면에 형성된 홈에 의하여 토출밸브가 원활하게 작동되며, 이로 인해 토출공을 통한 압축유체의 토출이 정상적으로 이루어지는 이점이 있다.Therefore, the discharge valve is smoothly operated by the groove formed in the contact surface of the contact portion, which is advantageous in that the discharge of the compressed fluid through the discharge hole is normally performed.
또한, 홈에 존재하는 오일로 인하여 토출밸브가 닫히면서 접촉부와의 충돌소음을 저감시키는 이점이 있다.In addition, the oil present in the groove has the advantage of reducing the noise of the collision with the contact while the discharge valve is closed.
