용기(a)에 기밀사태로 덮어 끼워지는 덮개판(1)에 통기구멍(2)과 밸브 볼임고정 구멍(3)을 뚫어 형성한 밸브 시이트(4)를 형성하고, 이 밸브 볼임고정 구멍 (3)에 볼임고정 로드(5)를 빠지지 않는 상태로 덮어 끼우고, 이 볼임고정 로드(5)의 상단에 정상적인 상태에서는 통기구멍(2)을 폐색하고, 위쪽으로의 흡인력이 작용 하였을때 또는 중앙부를 아래쪽으로 눌렀을때 주변부가 부상하여 통기구멍(2)을 통기상태로 하는 유연성을 가지는 밸브반(6)을 형성한 것을 특징으로 하는 감압용기.A valve seat 4 formed by drilling a vent hole 2 and a valve ball fixing hole 3 is formed in a cover plate 1 to be covered with a gastight state in the container a, and the valve ball fixing hole 3 And cover the hole fixing rod (5) in the state of not falling out, and block the vent hole (2) in the normal state on the top of the ball fixing rod (5), and when the suction force upward A pressure reducing container characterized by forming a valve panel (6) having a flexibility to allow a periphery to rise when pressed downward to bring the vent hole (2) into a ventilated state. 핸들(8)을 형성한 피스턴 로드체(9)를 펌프통(7)에 대하여 왕복으로 당기고 눌러서 펌프통(7)의 하단 개구부에서 공기를 흡인하는 수압식(手押式)진공펌프에 있어서, 피스턴 로드체(9)의 하단부에, 피스턴 로드체(9)보다 직경이 큰 밸브부 (19)를 형성하며, 이 밸브부(19)에 0링타입의 링 밸브(20)를 끼워맞춤하는 밸브홈 (21)을 형성하고, 밸브홈(21)의 깊이를 밸브홈(21)내에 링벨브(20)를 끼워붙였을때, 링밸브(20)가 밸브부(19)의 둘레면 보다도 조금 돌출하여 펌프통(7)내를 기밀 상태로 구분하여 미끄러져 움직이도록 형성하고, 밸브홈(21)의 폭을 링밸브 (20)가 링밸브(20)보다도 조금 넓은 폭으로 형성하여, 밸브부(19)의 상벽부(19′)의 1개소를 홈바닥 깊이까지 절결하여 공기 빠지는 통로(22)를 형성하고, 이 공기 빠지는 통로(22)와 연결되어 통하는 상태로 밸브홈의 바닥부에 공기 빠지는 홈(23)을 형성하여, 펌프통(7)의 상단부와 피스턴 로드체(9)와 바깥둘레면과의 사이에 미끄러져 움직이는 것과 공기를 뺄수 있는 간격(24)을 형성시킨 것을 특징으로 하는 용기내를 감압하는 수압식(手押式)진공펌프.In a hydraulic vacuum pump that draws air from the lower end opening of the pump barrel 7 by pulling the piston rod body 9 having the handle 8 in a reciprocating manner and pressing the pump cylinder 7. At the lower end of the piston rod body 9, a valve portion 19 having a diameter larger than that of the piston rod body 9 is formed, and a valve for fitting a ring ring 20 of a zero ring type to the valve portion 19 is provided. When the groove 21 is formed and the depth of the valve groove 21 is fitted with the ring valve 20 in the valve groove 21, the ring valve 20 protrudes slightly from the circumferential surface of the valve portion 19. The inside of the pump cylinder 7 is formed so as to slide in a gastight state, and the width of the valve groove 21 is formed so that the ring valve 20 is slightly wider than the ring valve 20, and the valve portion 19 The upper wall portion 19 'of the upper wall portion 19' is cut to the depth of the groove bottom to form an air escape passage 22, and is connected to the air escape passage 22 to communicate with the valve groove. The groove 23 is provided with air deflation, and the gap between the upper end of the pump cylinder 7 and the piston rod body 9 and the outer circumferential surface and the gap 24 for releasing air are formed. A hydraulic type vacuum pump for depressurizing a container. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
