Abstract

본 발명은 흡입밸브 및 토출밸브가 열리는 초기에 쉽게 열리도록 하여 흡입냉매량을 증가시키거나, 실린더내부의 압력이 과압축되지 않도록 하여 압축기의 전기입력을 줄이고 실린더 내부가스의 온도의 과열을 줄여 흡입측으로의 전열을 방지하는 효과와, 흡입밸브 및 토출밸브가 닫힐 때에 신속하게 닫힐 수 있도록 탄성계수를 증가시켜 역유동을 방지하여 압축기의 냉동능력을 증가시키도록 발명한 밀폐형 왕복동식 압축기의 밸브조립체에 관한 것으로, 냉매가스를 흡입 및 토출시키도록 흡입구(226a)와 토출구(226b)가 형성되어 실린더(223)와 실린더헤드(227)사이에 조립되는 밸브플레이트(226)와, 실린더(223)와 밸브플레이트(226) 사이에 고정단을 고정설치하여 자유단을 열리는 영향을 절곡되어 소성변형한 흡입측 백업스프링(228)과 밸브플레이트(226)와 흡입측 백업스프링(228) 사이에 고정단을 고정설치하여 밸브플레이트(226)의 흡입구(226a)를 자유단이 개폐시기에 따라 다르게 개폐되도록 하는 흡입밸브(224)와, 실린더헤드(227)와 밸브플레이트(226)사이에 고정단을 고정설치하여 자유단을 열리는 방향으로 절곡되어 소성변형한 토출측 백업스프링(229)과, 밸브플레이트(226)와 토출측 백업스프링(229) 사이에 고정단을 고정설치하여 밸브플레이트(226)의 토출구(226b)를 자유단이 개폐시기에 따라 다르게 개폐되독록 하는 토출밸브(225)와, 압축가스의 누설을 방지하는 패킹(230)으로 구성된 것이다.According to the present invention, the suction valve and the discharge valve can be easily opened at the initial stage of opening, thereby increasing the suction refrigerant amount, or preventing the pressure inside the cylinder from being overcompressed, thereby reducing the electrical input of the compressor and reducing the overheating of the temperature of the gas inside the cylinder. To the valve assembly of the hermetic reciprocating compressor invented to increase the refrigerating capacity of the compressor by preventing the reverse flow by increasing the elastic modulus so that the suction valve and the discharge valve can be closed quickly when the intake valve and the discharge valve are closed. The suction port 226a and the discharge port 226b are formed to suck and discharge the refrigerant gas, and the valve plate 226 and the cylinder 223 and the valve plate are assembled between the cylinder 223 and the cylinder head 227. The suction end backup spring 228 and the valve plate 226 that are plastically deformed by bending the effect of opening the free end by fixing the fixed end between the two ends 226. Inlet valve 224, the cylinder head 227 and the inlet valve 224 to securely install the fixed end between the suction side backup spring 228 so that the free end of the inlet 226a of the valve plate 226 according to the opening and closing time, The fixed end is fixed between the valve plate 226 and the fixed end is fixed between the discharge side backup spring 229 and the valve plate 226 and the discharge side backup spring 229 which are bent in the direction of opening the free end and plastically deformed. The discharge port 226b of the valve plate 226 is configured to have a discharge valve 225 for opening and closing the free end of the valve plate 226 differently according to opening and closing times, and a packing 230 for preventing leakage of compressed gas.
