Description

밀폐형 압축기의 흡입 및 토출밸브 어셈블리{SUCKING AND DISCHARGE VALVE ASSEMBLY OF A AIRTIGHT COMPRESSOR}SUCKING AND DISCHARGE VALVE ASSEMBLY OF A AIRTIGHT COMPRESSOR}

본 발명은 밀폐형 압축기의 흡입 및 토출밸브 어셈블리에 관한 것으로서, 보다 상세하게는 코킹작업의 횟수를 줄임과 아울러 불필요한 부품의 사용을 줄일 수 있는 밀폐형 압축기의 흡입 및 토출밸브 어셈블리에 관한 것이다.The present invention relates to a suction and discharge valve assembly of a hermetic compressor, and more particularly, to a suction and discharge valve assembly of a hermetic compressor that can reduce the number of caulking operations and reduce the use of unnecessary parts.

일반적으로 압축기는 기계적 에너지를 압축성 유체의 압축에너지로 변환시키는 것으로, 저압의 증발기에서 냉매가스를 흡입하고, 이 압력을 응축압력까지 증가시키는 작용을 하는 것으로서, 왕복압축기. 회전압축기. 터보압축기형이 있다.In general, a compressor converts mechanical energy into compressed energy of a compressive fluid. The compressor absorbs refrigerant gas in a low pressure evaporator and increases the pressure to a condensation pressure. Rotary compressors. There is a turbo compressor type.

압축기는 냉장고나 공기조화기 등에 사용되고 있으며, 냉장고에 사용되는 경우 냉장고 내부를 저열원으로 하고, 외부를 고열원으로 하는 저비등점의 냉매의 포화증기를 고압으로 압축하여 응축기로 유동시키게 된다.The compressor is used in a refrigerator or an air conditioner, and when used in a refrigerator, the inside of the refrigerator is used as a low heat source, and the saturated steam of a low boiling point refrigerant having the outside as a high heat source is compressed to a high pressure and flowed to a condenser.

응축기에서는 고온, 고압의 냉매로부터 증발의 잠열이 냉장고 외부의 고열원으로 방출되어 액체상태의 냉매가스로 상변화를 일으키고, 이 액상의 냉매가스가 팽창밸브를 통과하여 저온, 저압으로 스로톨링된 후 증발기로 유입된다.In the condenser, latent heat of evaporation is released from the high-temperature and high-pressure refrigerant to a high heat source outside the refrigerator, causing a phase change to a liquid refrigerant gas. The liquid refrigerant gas is throttled to low temperature and low pressure through an expansion valve. It enters the evaporator.

한편, 증발기에서 저온, 저압의 냉매가스는 대부분 액상으로 냉장고 내부의 저열원으로부터 잠열을 흡수하여 포화증기상태의 냉매가스로 상변화를 일으킨 후 다시 압축기로 유입됨으로서 냉동사이클을 구성하게 되며, 압축기에는 고압가스의 토출을 위해 개폐되는 흡입 및 토출밸브 어셈블리가 구비된다.On the other hand, the refrigerant gas of low temperature and low pressure in the evaporator mostly absorbs latent heat from the low heat source inside the refrigerator as a liquid phase, changes phase into a saturated vapor refrigerant gas, and then flows back into the compressor to form a refrigeration cycle. A suction and discharge valve assembly is provided that opens and closes to discharge the high pressure gas.

An exploded perspective view showing the main part of the valve assembly.

도시된 바와 같이, 종래의 밀폐형 압축기의 흡입 및 토출밸브 어셈블리(10)는 밸브커버(11)하측에 다수의 철판(12,13)이 순차적으로 브레이징 용접되고, 철판(13)의 하측에 흡입 및 토출포트(14a,14b)가 형성되는 밸브플레이트(14)가 결합되며, 토출포트(14a)를 개폐시키는 토출밸브(15)와 토출밸브(16)의 개폐영역을 탄성적으로 한정시키는 백킹스프링(16)과 토출밸브(15)의 응답특성을 향상시키는 밸브스토퍼(17)가 순차적으로 서로 겹쳐져서 밸브플레이트(14)상에 코킹에 의해 설치된다.As shown, the suction and discharge valve assembly 10 of the conventional hermetic compressor has a plurality of iron plates 12 and 13 are sequentially brazed and welded to the lower side of the iron plate 13 under the valve cover 11. The valve plate 14 having the discharge ports 14a and 14b are coupled to each other, and the backing spring elastically restricts the opening / closing area of the discharge valve 15 and the discharge valve 16 to open and close the discharge port 14a. 16 and the valve stopper 17 which improves the response characteristic of the discharge valve 15 are sequentially overlapped with each other and are installed by caulking on the valve plate 14.

흡입 및 토출밸브 어셈블리(10)는 외측의 토출측에 고온 및 고압의 냉매가스가 토출시 압력의 맥동에 의한 소음발생을 감소시키는 토출머플러(20)가 설치된다.The suction and discharge valve assembly 10 is provided with a discharge muffler 20 that reduces noise generated by pulsation of pressure when the refrigerant gas of high temperature and high pressure is discharged on the discharge side of the outside.

이와 같은 종래의 밀폐형 압축기의 흡입 및 토출밸브 어셈블리(10)의 밸브스토퍼(17)는 일단이 토출밸브(15)와 백킹스프링(16)의 각각의 일단과 함께 리벳(R)으로 코킹되어 밸브플레이트(14)상에 결합되며, 타단은 역시 리벳(R)으로 코킹되어 밸브플레이트(14)상에 결합된다.The valve stopper 17 of the suction and discharge valve assembly 10 of the conventional hermetic compressor is cocked with a rivet R together with one end of each of the discharge valve 15 and the backing spring 16 to the valve plate. Coupling on (14), the other end is also cocked with rivets (R) to engage on valve plate (14).

따라서, 종래의 밀폐형 압축기의 흡입 및 토출밸브 어셈블리(10)는 양단이 코킹되어 밸브플레이트(14)상에 결합되는 밸브스토퍼(17)로 인해 코킹작업 횟수가 증가할 뿐만 아니라 리벳(R)의 사용량이 증가하여 조립공정이 복잡해질 뿐만 아니라 제조단가를 상승시키는 문제점을 가지고 있었다.Therefore, the suction and discharge valve assembly 10 of the conventional hermetic compressor not only increases the number of caulking operations but also the amount of the rivet R due to the valve stopper 17 coupled to the valve plate 14 at both ends. This increase has not only complicated the assembly process but also has a problem of increasing the manufacturing cost.

본 발명은 상술한 종래의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 밸브스토퍼를 철판에 일체로 형성함으로써 코킹작업의 횟수를 줄임과 아울러 불필요한 부품의 사용을 줄여서 조립공정을 단순화시킴과 아울러 제조단가를 절감시키는 밀폐형 압축기의 흡입 및 토출밸브 어셈블리를 제공하는데 있다.The present invention is to solve the above-mentioned conventional problems, an object of the present invention is to simplify the assembly process by reducing the number of caulking operations and reducing the use of unnecessary parts by integrally forming the valve stopper on the iron plate To provide a suction and discharge valve assembly of the hermetic compressor to reduce the unit cost.
