Description

자동차의 에어브리더 {Air breather in an automobile}Air breather in an automobile

본 발명은 자동차의 에어브리더(air breather)에 관한 것으로서, 보다 상세하게는 작업자가 용이하게 에어배출 작업을 할 수 있도록 하고, 에어브리딩시 에어의 역방향 유입을 방지하는 자동차의 에어브리더에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air breather of an automobile, and more particularly, to an air breather of an automobile, which enables an operator to easily perform an air discharge operation and prevents reverse inflow of air during air breathing.

일반적으로 자동차의 브레이크 장치나 클러치 장치 등의 작동을 위한 유압 장치는, 도 1에 도시된 바와 같이, 액체인 작동유를 매개체로하여 각 기구를 작동시키므로 외부로부터 유압라인에 기체가 유입되거나, 작동유의 기화로 인해 내부에 기포가 발생하면 작동유를 통한 기구의 작동이 제대로 이루어지지 않는다. 따라서, 이러한 유압장치는 유압라인에 형성된 기포를 배출시키기 위한 에어브리더(1)가 설치된다.In general, a hydraulic device for operating a brake device or a clutch device of an automobile, as shown in FIG. 1, operates each mechanism through a hydraulic fluid as a medium, so that gas is introduced into the hydraulic line from the outside, or If bubbles are generated inside due to vaporization, the operation of the mechanism through the working oil will not work properly. Therefore, such a hydraulic device is provided with an air breather 1 for discharging bubbles formed in the hydraulic line.

종래의 자동차의 에어브리더는, 도 2 및 도 3에 도시된 바와 같이, 실린더(2) 및 본체(3)를 포함한다.A conventional air breather of a motor vehicle includes a cylinder 2 and a main body 3, as shown in Figs.

실린더(2)는 내주면의 일부분에 나사가 형성된 구멍(2a)이 소정 깊이로 형성되고, 이 구멍(2a)의 저면부는 원추 형상으로 테이퍼져 있다. 또한, 구멍(2a)의 저면부의 중앙을 통해 유체가 유동하여 구멍(2a)의 내부로 유입될 수 있도록 구멍(2a)의 직경보다 작은 직경을 갖는 통로(2b)가 형성되어 있다.The cylinder 2 has a hole 2a in which a screw is formed in a part of the inner circumferential surface to a predetermined depth, and the bottom portion of the hole 2a is tapered in a conical shape. In addition, a passage 2b having a diameter smaller than the diameter of the hole 2a is formed so that fluid can flow through the center of the bottom portion of the hole 2a and flow into the inside of the hole 2a.

본체(3)는 실린더(2)의 내주면에 형성된 구멍(2a)의 나사와 결합하도록 외주면에 나사가 형성되고, 통로(2b)에 대응되는 일단에 본체(3)의 직경보다 작은 직경을 가진 테이퍼진 돌출부(3a)를 가진다. 이 돌출부(3a)가 통로(2b)를 개폐하게 된다. 또한, 본체(3)의 내부에는 'T'자 형상의 연통로(3b)가 형성되어 있다.The main body 3 has a screw formed on the outer circumferential surface to engage with the screw of the hole 2a formed on the inner circumferential surface of the cylinder 2, and a taper having a diameter smaller than the diameter of the main body 3 at one end corresponding to the passage 2b It has a true protrusion 3a. The protrusion 3a opens and closes the passage 2b. In addition, a communication path 3b having a 'T' shape is formed inside the main body 3.

이러한 구성으로, 일반적으로 두사람이 한조가 되어 한사람이 페달을 밟아 실린더(2) 내부의 압력이 증가된 상태를 유지한다. 이때, 다른 한사람이 나사결합된 본체(3)를 풀어 본체(3)의 돌출부(3a)가 실린더(2)로부터 떨어져 유체가구멍(2a)의 내부로 흘러나오게 된다. 실린더(2)의 구멍(2a)으로 유출된 유체가 이 연통로(3b)를 통해 에어와 함께 실린더(2) 외부로 배출된다. 이 과정을 수차례 반복 실시한다. 더이상 에어가 배출되지 않으면, 본체(3)를 실린더(2)에 결합한다.In such a configuration, two people are generally a pair, and one person presses a pedal to maintain a state in which the pressure inside the cylinder 2 is increased. At this time, the other person unscrews the main body 3, which is screwed on, and the protrusion 3a of the main body 3 is separated from the cylinder 2 so that the fluid flows into the inside of the hole 2a. The fluid which flows out into the hole 2a of the cylinder 2 is discharged | emitted out of the cylinder 2 with air through this communication path 3b. Repeat this process several times. When no more air is discharged, the body 3 is coupled to the cylinder 2.

그러나, 상기와 같은 종래의 자동차의 에어브리더는 에어의 배출을 위해 본체를 풀고 조이는 작업을 반복적으로 실시해야 하며, 2인 1조가 되어 실시하기 때문에 서로의 싸인이 맞지 않아 에어가 역방향으로 유입되는 단점이 있었다.However, the air breather of the conventional vehicle as described above should be repeatedly performed to loosen and tighten the body for the discharge of air, and because it is carried out in a pair of two people, the air is introduced in the reverse direction because the sign is not matched with each other There was this.

본 발명은, 상기와 같은 점들을 감안하여 안출된 것으로, 에어브리딩 작업을 혼자서도 할 수 있고, 에어브리딩시 에어의 역방향 유입을 방지하는 자동차의 에어브리더를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide an air breather for an automobile which can perform air breathing work alone and prevent the reverse flow of air during air breathing.

Preferably, it comprises a housing having a through hole in communication with the passage of the cylinder and coupled between the cylinder and the body to guide the spring.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 자동차의 에어브리더는, 도 4 및 도 5에 도시된 바와 같이, 실린더(10), 본체(20), 밸브볼(30) 및 스프링(40)을 포함한다.As shown in FIGS. 4 and 5, the air breather of the vehicle according to the present invention includes a cylinder 10, a main body 20, a valve ball 30, and a spring 40.

실린더(10)는 내주면에 나사가 형성된 구멍(10a)이 소정 깊이로 형성되고, 이 구멍(10a)의 저면부의 중앙을 통해 구멍(10a)의 직경보다 작은 직경을 갖는 통로(10b)가 형성된다.The cylinder 10 has a hole 10a having a screw formed in the inner circumferential surface thereof to a predetermined depth, and a passage 10b having a diameter smaller than the diameter of the hole 10a is formed through the center of the bottom portion of the hole 10a. .

본체(20)는 외주면에 실린더(10)의 내주면에 형성된 구멍(10a)의 나사와 결합되고, 통로(10b)에 대응되는 일단에 테이퍼진 돌출부(20a)가 형성되어 통로(10b)를 개폐하며, 내부에는 'T'자 형상의 연통로(20b)가 형성된다.The main body 20 is coupled to the screw of the hole 10a formed on the inner circumferential surface of the cylinder 10 on the outer circumferential surface, and a tapered protrusion 20a is formed at one end corresponding to the passage 10b to open and close the passage 10b. Inside, a communication path 20b having a 'T' shape is formed.

밸브볼(30)은 본체(20)의 돌출부(20a)에서 상부에 위치하여 실린더(10)의 통로(10b)를 개폐한다.The valve ball 30 is located at an upper portion of the protrusion 20a of the main body 20 to open and close the passage 10b of the cylinder 10.

스프링(40)은 본체(20)의 돌출부(20a)와 밸브볼(30) 사이에 설치되어 탄성적인 압력을 가하게 된다.The spring 40 is installed between the protruding portion 20a of the main body 20 and the valve ball 30 to apply elastic pressure.

바람직하게는, 실린더(10)의 통로(10b)와 연통되는 관통홀(50a)을 가지고, 실린더(10)와 본체(20) 사이에 결합되어 스프링(40)을 안내하는 하우징(50)이 삽입, 결합된다.Preferably, a housing 50 having a through hole 50a communicating with the passage 10b of the cylinder 10 and coupled between the cylinder 10 and the main body 20 to guide the spring 40 is inserted. , Are combined.

이러한 구성으로, 에어브리딩시 본체(20)를 2∼3㎜ 열고 에어브리딩을 위해 페달을 수차례 밟으면, 실린더(10)에서 발생된 높은 유압이 밸브볼(30)을 밀어올려 유체가 에어와 함께 본체(20)의 연통로(20b)를 통해 유출되게 된다. 이때, 페달에서 발을 떼더라도 본체(20)의 돌기부(20a)의 선단에 설치된 스프링(40)의 탄성력에의해 밸브볼(30)이 원위치되어 통로(10b)를 막기 때문에 에어가 역방향으로 유입되지 않는다.With this configuration, when the body 20 is opened 2-3 mm during air bleeding and the pedal is pressed several times for air bleeding, the high hydraulic pressure generated in the cylinder 10 pushes the valve ball 30 so that the fluid moves with the air. It flows out through the communication path 20b of the main body 20. At this time, even when the foot is released from the pedal, the valve ball 30 is repositioned by the elastic force of the spring 40 installed at the tip of the protrusion 20a of the main body 20, thereby preventing the passage 10b. Do not.

본 발명의 자동차의 에어브리더는 두사람이 하던 에어브리딩 작업을 혼자서도 할 수 있게 되어 작업효율이 향상되고, 에어브리딩시 에어의 역방향 유입을 방지하는 효과가 있다.Air breather of the vehicle of the present invention can be carried out by the air breathing work alone, the work efficiency is improved, there is an effect of preventing the reverse inflow of air during air breathing.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below. It may be changed.
