자동차의 진공식 제동 배력장치용 첵밸브Check valve for vacuum braking booster of automobile

본 고안은 기관에서 발생하는 최고의 부압을 유지하고 주행할 때 흡기 매니폴드안의 부압의 변화에 다른 영향을 방지하기 위하여 설치하는 자동차의 진공식 제동 배력장치용 첵밸브에 관한 것으로, 더 상세히는 브레이크 부우스터와 흡기 매니폴드를 연결하는 호스에 설치된 자동차의 배력식 브레이크용 첵밸브에 관한 것이다.The present invention relates to a check valve for a vacuum braking power booster of a vehicle installed to maintain the highest negative pressure generated in an engine and to prevent other influences on the negative pressure change in the intake manifold. It relates to a check valve for a hydraulic brake of a vehicle installed in a hose connecting a woster and an intake manifold.

제1도는 종래의 첵밸브 설치상태를 보인 자동차의 진공식 제동 배력장치의 구성도이다.1 is a configuration diagram of a vacuum brake power supply apparatus for a vehicle showing a conventional check valve installation state.

제1도에 도시한 바와같이, 진공식 제동 배력장치는 브레이크 부우스터(10)를 사용하며, 진공은 일반적으로 흡기 매니폴드(20)의 흡입 부압을 이용한다. 종래의 첵밸브(40)는 브레이크 부우스터(10)와 흡기 매니폴드(20)를 연결하는 호스(30)의 중간에 설치되며, 기관에서 발생하는 최고의 부압을 유지하고 주행할 때 흡기 매니폴드(20)안의 부압의 변화에 따른 영향을 방지하는 기능을 한다.As shown in FIG. 1, the vacuum braking booster uses the brake booster 10, and the vacuum generally uses the suction negative pressure of the intake manifold 20. As shown in FIG. The conventional check valve 40 is installed in the middle of the hose 30 connecting the brake booster 10 and the intake manifold 20, and maintains the highest negative pressure generated in the engine and runs when the intake manifold ( 20) It prevents the influence of the change of negative pressure inside.

그런데, 종래의 첵밸브(40)는 분리형으로서 호스(30)의 중간에 설치되기 때문에 호스(30)와의 연결부위로 공기의 누출이 발생되고 밸브(42)가 강체로 되어 있기 때문에 밸브(42)와 본체(41)의 밸브시트(43)와의 밀착이 불량하여 브레이크의 제동능력을 저하시키는 요인이 되었다.However, since the conventional check valve 40 is detachably installed in the middle of the hose 30, air leaks to the connection portion with the hose 30, and the valve 42 is made of a rigid body. Adhesion between the valve seat 43 of the main body 41 and the main body 41 is a factor of lowering the braking ability of the brake.

본 고안은 이러한 종래의 문제점을 해소하기 위한 것으로, 첵밸브를 브레이크 부우스터와 일체형으로 설치하여 공기의 누출을 방지하고 밸브와 밸브시트의 밀착이 양호한 구조로 된 자동차의 진공식 제동 배력장치용 첵밸브를 제공하고자 한다.The present invention is to solve such a conventional problem, 첵 for the vacuum braking power booster of automobiles in which the valve is integrally installed with the brake booster to prevent the leakage of air and the valve and the valve seat are in close contact. To provide a valve.

본 고안은 브레이크 부우스터(100)와 흡기 매니폴드(200)의 사이에 설치되는 자동차의 진공식 제동 배력장치용 첵밸브(400)에 있어서, 원통형 본체(410)와 상기 본체(410)에 내장되는 벨로즈형의 밸브(420)를 구비하고 상기 브레이크 부우스터(100)의 본체(410)에는 보스(110)와 상기 보스(110)의 중앙과 그 주변에 관통공(120)과 부압홀(130)을 형성하여 상기 본체(410)는 보스(110)에 연결하고 상기 밸브(420)는 관통공(120)에 연결하여, 흡기 매니폴드(200)의 부압에 따라 상기 부압홀(130)이 개방될 수 있도록 한 것에 그 특징이 있다.The present invention is built in the cylindrical body 410 and the main body 410 in the check valve 400 for a vacuum braking power booster of a vehicle installed between the brake booster 100 and the intake manifold 200. The bellows-type valve 420 is provided, and the main body 410 of the brake booster 100 includes a boss 110 and a through hole 120 and a negative pressure hole in and around the boss 110. 130 to form the main body 410 is connected to the boss 110 and the valve 420 is connected to the through hole 120, the negative pressure hole 130 in accordance with the negative pressure of the intake manifold 200 Its feature is that it can be opened.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

제2도는 본 고안에 따른 첵밸브 설치상태를 보인 자동차의 진공식 제동 배력장치의 구성도이다.2 is a block diagram of a vacuum braking power supply system of a vehicle showing a check valve installation state according to the present invention.

제2도에 도시한 바와같이, 첵밸브(400)는 브레이크 부우스터(100)에 일체로 설치되고 그 일측이 흡기 매니폴드(200)와 호스(300)와 연결된다.As shown in FIG. 2, the check valve 400 is integrally installed in the brake booster 100 and one side thereof is connected to the intake manifold 200 and the hose 300.

첵밸브(400)의 본체(410)는 원통형으로써 그 일측에 브레이크 부우스터(100)의 보스(110)에 나사체결되며, 밸브(420)는 고무재로써 일측이 개방된 자루형태로 형성함과 동시에 벨로즈형으로 형성하여 신축될 수 있도록 하였다. 밸브(420)의 내면 바닥부위에 부착된 원판형 강판(421)은 밸브(420)의 개폐작용을 원활하게 하기 위한 것이다.본체 The main body 410 of the valve 400 is cylindrical and screwed to the boss 110 of the brake booster 100 at one side thereof, and the valve 420 is formed in a bag shape with one side opened with a rubber material. At the same time, it was formed bellows so that it could be stretched. The disk-shaped steel sheet 421 attached to the bottom of the inner surface of the valve 420 is for smoothly opening and closing the valve 420.

보스(110)는 본체(410)를 브레이크 부우스터(100)에 결합시키기 위한 것으로 리턴스프링이 설치되는 쪽에 형성한다. 그리고 보스(110)의 중앙에 형성된 관통공(120)은 밸브(420)의 개방부위를 결합시키기 위한 것이며 관통공(120)의 주변에 형성된 수개의 부압홀(130)은 흡기 매니폴드(200)의 부압작용시 밸브(420)에 의하여 개방될 수 있도록 한 것이다.The boss 110 is for coupling the main body 410 to the brake booster 100 and is formed on the side where the return spring is installed. In addition, the through hole 120 formed at the center of the boss 110 is used to couple the open portion of the valve 420, and the several negative pressure holes 130 formed around the through hole 120 are intake manifolds 200. It is to be opened by the valve 420 during the negative pressure of the.

이와같이 본 고안은, 흡기 매니폴드(200)에 부압작용시 밸브(420) 내에 공기가 들어가 팽창되면서 부압홀(130)이 개방되므로 첵밸브(400)가 열린상태가 되고, 정압이 작용하면 밸브(420)가 압축되어 부압홀(130)이 폐쇄되므로 첵밸브(400)가 닫힌상태가 된다.As such, the present invention, when the negative pressure acts on the intake manifold 200, the air enters the valve 420 and expands so that the negative pressure hole 130 is opened, so that the valve 400 is opened and the positive pressure acts on the valve ( 420 is compressed and the negative pressure hole 130 is closed, so the valve 400 is in a closed state.

상술한 바와같이 본 고안에 따른 첵밸브(400)는 브레이크 부우스터(100)와 일체형으로 설치되므로 공기의 누출을 방지할 수 있고 벨로즈형으로 된 밸브(420)의 신축작용에 의하여 부압홀(130)을 개폐하므로 오작동의 우려가 거의 없다.As described above, the check valve 400 according to the present invention is installed integrally with the brake booster 100 so that air leakage can be prevented and the negative pressure hole can be prevented by the expansion and contraction of the valve 420 made of a bellows type. There is almost no risk of malfunction due to opening and closing of 130).
