Description

밀폐형 압축기의 밸브장치Valve device of hermetic compressor

본 발명은 밀폐형 압축기의 밸브장치에 관한 것으로, 더욱 상세하게는 압축기의 압축 작용시 냉매가스의 흡입 및 토출이 원활하게 이루지도록 한 밀폐형 압축기의 밸브장치에 관한 것이다.The present invention relates to a valve device of a hermetic compressor, and more particularly to a valve device of a hermetic compressor to facilitate the suction and discharge of the refrigerant gas during the compression action of the compressor.

일반적으로 밀폐형 압축기는 도 1에 도시된 바와 같이, 상,하부 케이스(1),(2)의 내부에 고정자(3)와 회전자(4)로 이루어지는 전동 기구부(5)와, 회전자(4)의 중앙에 압입 고정된 크랭크 샤프트(6)의 회전 동작에 의해 냉매를 흡입하여 압축시킨 후 토출시키는 압축 기구부(7)로 구성되어 있다.In general, the hermetic compressor includes an electric mechanism part 5 and a rotor 4 including a stator 3 and a rotor 4 inside the upper and lower cases 1 and 2, as shown in FIG. It consists of a compression mechanism part 7 which sucks and compresses a refrigerant | coolant by the rotation operation of the crankshaft 6 press-fitted in the center of the ().

압축 기구부(7)는 흡입관(8)을 통해 유입되는 냉매의 압축 공간을 이루는 실린더 블록(9)과, 이 실린더 블록(9)의 내부에서 크랭크 샤프트(6)의 회전에 의해 왕복 운동을 하는 피스톤(10)과, 실린더 블록(9)을 복개하는 실린더 헤드(11)와, 실린더 블록(9)과 실린더 헤드(11) 사이에 개재되어 실리더의 내부로 냉매를 흡입함과 아울러 압축된 냉매를 토출시키는 밸브장치(50)로 구성되어 있다.The compression mechanism 7 includes a cylinder block 9 which constitutes a compression space of the refrigerant flowing through the suction pipe 8 and a piston which reciprocates by the rotation of the crank shaft 6 inside the cylinder block 9. The cylinder head 11 covering the cylinder block 9 and the cylinder block 9 and the cylinder head 11 are interposed between the cylinder block 9 and the cylinder head 11 to suck refrigerant into the cylinder and to compress the refrigerant. It consists of the valve apparatus 50 which discharges.

상기 밸브장치(50)는 실린더 블록(9)의 상면으로부터 토출공(12a)이 형성된 흡입 밸브(12)와, 흡입 밸브(12)에 의해 개폐되고 중앙에 흡입공(13a)이 형성된 밸브 플레이트(13)와, 밸브 플레이트(13)의 흡입공(13a)를 기준으로 하단측 소정 위치에 형성된 토출공(13b)을 개폐하는 토출 밸브(14)와, 토출 밸브(14)의 개폐 영역을 규제하는 스톱 밸브(15)와, 토출 밸브(14)와 스톱 밸브(15)가 정위치에서 벗어나지 않도록 하는 키퍼(16) 등을 포함하여 구성되어 있다.The valve device 50 includes a suction valve 12 having a discharge hole 12a formed from an upper surface of the cylinder block 9 and a valve plate which is opened and closed by the suction valve 12 and has a suction hole 13a formed at the center thereof. 13, the discharge valve 14 for opening and closing the discharge hole 13b formed at a predetermined position on the lower side with respect to the suction hole 13a of the valve plate 13, and the opening and closing area of the discharge valve 14 The stop valve 15, the discharge valve 14, and the stop valve 15 are comprised including the keeper 16 etc. which do not leave a fixed position.

미설명 부호 17은 실린더 헤드(11)와 밸브 장치(50) 사이에 개재되어 냉매가스의 누설을 방지하는 실린더 헤드 가스겟이다.Reference numeral 17 is a cylinder head gasket interposed between the cylinder head 11 and the valve device 50 to prevent leakage of the refrigerant gas.

이와 같이 구성되어 있는 종래 기술에 의한 밀폐형 압축기는 압축기가 구동되어 크랭크 샤프트(6)가 회전되면, 피스톤(10)이 실린더내에서 왕복운동하여 냉매의 흡입, 압축 및 토출 과정이 이루어지는 바, 흡입관(8)을 통해 유입된 냉매는 흡입 머플러(8a)를 거쳐 실린더 헤드(11)의 흡입실(11a)로 유입되고, 계속해서 밸브 플레이트(13)의 흡입공(13a)을 통해 실린더의 내부로 흡입되어 피스톤(10)에 의해 압축된다.In the hermetic compressor according to the related art configured as described above, when the compressor is driven and the crankshaft 6 is rotated, the piston 10 reciprocates in the cylinder to inhale, compress, and discharge the refrigerant. The refrigerant introduced through 8) flows into the suction chamber 11a of the cylinder head 11 via the suction muffler 8a, and is then sucked into the cylinder through the suction hole 13a of the valve plate 13. And is compressed by the piston 10.

실린더내에서 압축된 냉매는 밸브 플레이트(13)의 토출공(13b)을 통해 토출 밸브(14)를 개방시키면서 토출되어 실린더 헤드(11)의 토출실(11b)과, 토출관(미도시)을 거쳐 압축기 케이스(1),(2)의 외부로 토출된다.The refrigerant compressed in the cylinder is discharged while opening the discharge valve 14 through the discharge hole 13b of the valve plate 13 to discharge the discharge chamber 11b of the cylinder head 11 and the discharge tube (not shown). It is discharged to the outside of the compressor case (1), (2).

상기와 같이 구성된 종래 밀폐형 압축기의 밸브장치에 있어서, 밸브 플레이트(13)의 중앙에 흡입공(13a)이 형성되어 있기 때문에, 냉매가스가 흡입공을 통하여 실린더 내부로 흡입되때, 흡입저항이 발생되지 않아 실린더 내부에는 냉매가스가 원활하게 흡입되어 피스톤(10)에 의해 압축된다.In the valve device of the conventional hermetic compressor configured as described above, since the suction hole 13a is formed in the center of the valve plate 13, the suction resistance is generated when the refrigerant gas is sucked into the cylinder through the suction hole. If not, the refrigerant gas is smoothly sucked into the cylinder and compressed by the piston 10.

그러나, 밸브 플레이트(13)의 중앙에 형성된 흡입공(13a)을 기준으로 하여 그 하부 방향으로 소정 거리 치우쳐져 한 개의 토출공(13b)이 형성되어 있기 때문에, 냉매 가스의 흡입시에는 흡입공을 통하여 흡입이 잘되나, 냉매가스의 토출시에는 그 토출이 원활하게 되지 않아 압축기의 성능이 저하되는 문제점이 있었다.However, since the one discharge hole 13b is formed in the lower direction with respect to the suction hole 13a formed in the center of the valve plate 13, one discharge hole 13b is formed. Although the suction is good, the discharge of the refrigerant gas is not smoothly discharged, there is a problem that the performance of the compressor is reduced.

본 발명은 상기와 같은 문제점을 해결하기 위해 압축기의 압축 작용시 냉매가스의 흡입 및 토출이 원활하게 이루지도록 한 밀폐형 압축기의 밸브장치를 제공하는 데 그 목적이 있다.An object of the present invention is to provide a valve device of a hermetic compressor to smoothly suck and discharge refrigerant gas during the compression operation of the compressor to solve the above problems.
