본 고안 자동차의 PCV밸브 (POSITIVE CRANK-CASE VENTILATION VALVE)에 관한 것으로써, 몸체와 밸브의 사이에 요홈을 가지는 링을 설치하는 동시에 밸브의 머리부에 평면부를 형성하여서 몸체와 밸브의 사이에서 발생되는 소음을 극소화 한 것이다.The present invention relates to a PCV valve (POSITIVE CRANK-CASE VENTILATION VALVE) of an automobile of the present invention. The noise is minimized.
블로바이 가스 환원장치라 불리우는 PCV밸브(5, POSITIVE CRANK-CASE VENTILATION VALVE)는 첨부도면 제1도 내지 제2도에 도시된 바와 같이 흡입부몸체(1)와 배출부몸체(3)의 사이에 스프링(2)을 가지는 밸브(4)를 설치하여 엔진의 피스톤 작동에 따라 배출부몸체(3)에서 흡입력이 발생되면 밸브(4)가 스프링(2)을 압축하며 배출부몸체(3)로 당겨져 흡입부몸체(1)로부터 블로바이 가스(BLOW-BY GAS)가 빨려들어오게 되는바, 상기 블로바이 가스가 흡입부몸체(1)와 밸브(4)의 사이로 짧은 시간에 빨려들어 오는 과정에서 밸브(4)가 진동을 일으키며 흡입부몸체(1)의 벽면과 부딪히며 소음을 발생하게 되는 것이다.A PCV valve 5, called a blow-by gas reducing device, is provided between the suction part body 1 and the discharge part body 3 as shown in FIGS. 1 to 2 of the accompanying drawings. When a suction force is generated in the discharge body 3 according to the operation of the piston of the engine by installing a valve 4 having a spring 2, the valve 4 compresses the spring 2 and is pulled by the discharge body 3. The blow-by gas is sucked from the suction part body 1, and the blow-by gas is sucked between the suction part body 1 and the valve 4 in a short time. (4) causes the vibration and hit the wall of the suction body (1) to generate noise.
따라서 본원 고안은 종래의 이러한 문제점을 해결하기 위하여 안출된 것으로써, 흡입부몸체와 밸브의 사이에 길이방향의 요홈을 가지는 가이드링을 끼워서 밸브가 상기 가이드링을 따라 슬라이딩되므로써 블로바이 가스의 흡입시 밸브의 떨림현상이 발생되지 않도록 한 것이다.Therefore, the present invention has been devised to solve such a problem in the prior art, by inserting a guide ring having a longitudinal groove between the suction body and the valve, the valve slides along the guide ring, so that the blow-by gas is sucked in. This is to prevent the shaking of the valve.
이하 첨부도면을 참고하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 흡입부몸체(1)내에 스프링(2)을 가지는 배출부몸체(3)가 설치되고, 상기 스프링(2)의 내경상에는 밸브(4)가 설치되어서 이루어진 자동차용PCV밸브(5)가 있어서, 상기PCV밸브(5)는 스프링(2)의 외경과 흡입부몸체(1)의 사이에 길이 방향의 요홈(6)을 가지는 가이드링(7)이 설치되어서 이루어진 것이다.According to the present invention, an inlet body 1 includes an outlet body 3 having a spring 2, and an inner diameter of the spring 2 is provided with a valve 4 for an automobile PCV valve 5. In this case, the PCV valve 5 is formed by a guide ring 7 having a groove 6 in the longitudinal direction between the outer diameter of the spring 2 and the suction body 1.
이를 좀더 상세히 설명하면 첨부도면 제3도 내지 제4도는 본 고안의 구성상태를 도시한 것으로써, PCV밸브(5)는 흡입부몸체(1)의 내부 일단에 배출부몸체(3)의 일단이 스프링(2)을 가지고 삽입되어져 있으며, 상기 스프링(2)의 내부에는 머리부(8)가 상기 스프링(2)의 선단에 얹혀진 상태로 밸브(4)가 설치되며, 상기 스프링(2)과 밸브(4)의 머리부(8) 사이에는 가이드링(7)이 끼워지되, 상기 밸브(4)의 머리부(8)에는 평면부(9)가 형성되어 있는 동시에 가이드링(7)은 내경상에 길이방향의 요홈(6)을 형성하여서 밸브(4)의 머리부(8) 외경이 가이드링(7)의 최소 내경상에 밀착된 상태로 슬라이딩 가능하도록 되어져 있다. 물론, 상기 밸브머리부(8)의 평면부(9)는 이웃하는 각 평면부(9) 사이의 면적이 최소한 흡입부몸체(1)의 흡입구(10)보다 같거나 다소 큰 상태를 유지할 수 있는 범위내에서 형성되어지게 된다.3 to 4 illustrate the configuration of the present invention, the PCV valve 5 has one end of the discharge body 3 at the inner end of the suction body 1. It is inserted with a spring (2), the valve (4) is installed in the state that the head 8 is mounted on the front end of the spring (2), the spring (2) and the valve A guide ring 7 is fitted between the heads 8 of 4, and a flat part 9 is formed in the head 8 of the valve 4, and at the same time, the guide ring 7 has an inner diameter. The groove 6 in the longitudinal direction is formed in the groove so that the outer diameter of the head 8 of the valve 4 is slidable in close contact with the minimum inner diameter of the guide ring 7. Of course, the planar portion 9 of the valve head 8 may maintain a state in which the area between each neighboring planar portion 9 is at least equal to or slightly larger than the inlet 10 of the intake body 1. It will be formed within the range.
한편, 상기와 같이 구성된 본 고안의 작용효과를 설명하면, 상기 PCV밸브(5)는 통상의 상태에서 밸브(4)의 머리부(8)가 흡입부몸체(1)의 가스흡입구(10)를 스프링(2)의 탄성에 의하여 막아주고 있는 상태를 유지하게 되며, 밸브머리부(8)의 평면부(9)는 가이드링(7)의 요홈(6)을 향하도록 곡면부(11)가 가이드링(7)의 최소 내경내에 슬라이딩 가능한 상태로 접촉되어져 있다. 따라서, 엔진의 흡기행정으로 배출부몸체(3)에 흡입력이 발생하면 밸브(4)는 스프링(2)을 누르고 가이드링(7)을 따라 흡입부몸체(1)쪽으로 밀리면서 흡입부몸체(1)의 흡입구(10)를 개방하게 되므로써 블로바이 가스가 흡입구(10)를 통하여 밸브머리부(8)의 평면부(9)와 가이드링(7)의 요홈(6)사이로 유입되게 되고 가스의 유입이 끝나면 즉, 엔진의 흡기행정이 끝나면 상기 밸브(4)는 스프링(2)의 복원력에 의하여 원상복귀되므로써 흡입부몸체(1)의 가스흡입구(10)를 폐쇄하게 되는 것이다. 즉, 상기 밸브(4)는 머리부(8)의 최대외경을 형성하는 평면부선단의 곡면부(11)가 가이드링(7)의 최소내경을 형성하는 곡면부(11')에서 슬라이딩되면서 왕복운동되게 되는 것이다.On the other hand, when explaining the operation and effect of the present invention configured as described above, the PCV valve 5 is the head portion 8 of the valve 4 in the normal state to the gas inlet 10 of the suction body (1) The state of being blocked by the elasticity of the spring (2) is maintained, and the flat portion (9) of the valve head (8) guides the curved portion (11) to face the groove (6) of the guide ring (7) It is in contact with the sliding state within the minimum internal diameter of the ring 7. Therefore, when suction force is generated in the discharge body 3 by the intake stroke of the engine, the valve 4 presses the spring 2 and pushes the suction body 1 toward the suction body 1 along the guide ring 7. By opening the suction port 10 of), the blow-by gas is introduced between the flat part 9 of the valve head 8 and the groove 6 of the guide ring 7 through the suction port 10, and the gas flows in. After the end of the intake stroke of the engine, the valve 4 is returned to its original state by the restoring force of the spring 2 to close the gas inlet 10 of the intake body 1. That is, the valve 4 reciprocates while the curved portion 11 at the tip of the flat portion forming the maximum outer diameter of the head 8 slides on the curved portion 11 'forming the minimum inner diameter of the guide ring 7. You will be exercised.
물론, 밸브(4)가 가이드링(7)의 내벽에 밀착되어 빠르게 축방향으로 왕복운동 하므로써 발생되는 열은 블로바이가스에 기화 상태로 존재하는 오일로써 충분히 냉각 및 윤활작용될 수 있는 것이다.Of course, the heat generated by the valve 4 being in close contact with the inner wall of the guide ring 7 and rapidly reciprocating in the axial direction can be sufficiently cooled and lubricated with oil existing in the blow-by gas.
이상에서 설명된 바와 같은 본 고안은 밸브의 머리부가 가이드링의 내경에 밀착되어 슬라이딩 운동되므로써 상기 밸브가 축방향을 중심으로 좌우로 유동되는 현상 및 이로 인하여 상기 밸브가 흡입부몸체의 내부벽에 부딪히는 소음의 발생들을 방지할 수 있는 장점을 지니는 것이다.The present invention as described above is the phenomenon that the valve flows to the left and right about the axial direction due to the sliding movement of the head of the valve in close contact with the inner diameter of the guide ring and thereby the noise that the valve hits the inner wall of the suction body Has the advantage of preventing the occurrence of.
