본 발명은 진공펌프를 구비한 알터네이터의 진공펌프용 밸브구조에 대한 것으로, 더 상세하게는 밸브변의 구조를 개량하여 이물질의 침투 또는 일부 손상이 발생하여도 밸브로서의 기능을 상실하지 않도록 하여 수명이 연장되도록 하는데 특징이 있다.The present invention relates to a valve structure for an alternator provided with a vacuum pump for a vacuum pump, and more particularly, to improve the structure of the valve valve to extend the life of the valve to prevent loss of function as a valve even if foreign matter infiltration or partial damage occurs. It is characteristic to make it possible.

일반적으로 차량의 주행 중 발전을 담당하는 알터네이터(10)는 모델에 따라 도 1에서 보인 바와 같이 진공펌프(20)를 구비하는 것이 있으며, 이때의 진공은 브레이크용 부압으로 사용하게 된다.In general, the alternator 10 in charge of power generation while driving the vehicle has a vacuum pump 20 as shown in Figure 1, depending on the model, the vacuum is used as a negative pressure for the brake at this time.

한편, 상기와 같은 진공펌프(20)에는 체크밸브(30)가 사용되는 바, 종래의 체크밸브 구성을 도 2 또는 도 3에서 볼 수 있다.On the other hand, the check valve 30 is used in the vacuum pump 20 as described above, the conventional check valve configuration can be seen in Figure 2 or 3.

도 2의 체크밸브(100)는 종래의 일반적인 밸브로서, 볼트 머리(111)를 가진 밸브몸체(110)와, 그 내부의 테이퍼면(112)에 접촉되도록 내장하되, 반구형으로 이루어진 밸브변(120)과, 상기 밸브변의 후방에 탄설시킨 복귀 스프링(130)과, 복귀 스프링(130)의 이탈을 방지하는 스톱퍼(140)로 이루어 진다.The check valve 100 of FIG. 2 is a conventional general valve, and is built in contact with the valve body 110 having the bolt head 111 and the tapered surface 112 therein, and has a hemispherical valve valve 120. ), A return spring 130 which is installed on the rear side of the valve side, and a stopper 140 for preventing the return of the return spring 130.

그러나 이와 같은 체크밸브(100)는 반구형 밸브변(120)이 테이퍼면(112)에 접하도록 하는 것이 특징인 바, 상기한 테이퍼면(112)이 절삭 가공시 미세하나마 정원이 아닌 타원으로 가공될 경우 누수가 생겨 기능을 상실하는 단점이 있으며, 또 한편으로는 상기한 반구형 밸브변(120)의 표면이 일부분이라도 마모나 손상이 생겼을 경우, 역시 기능을 상실하게 되는 단점이 있다.However, such a check valve 100 is characterized in that the hemispherical valve side 120 is in contact with the tapered surface 112, the tapered surface 112 is to be processed into an ellipse rather than a fine one when cutting. In this case, there is a drawback of the loss of function due to leakage, and on the other hand, even if a portion of the surface of the hemispherical valve valve 120 is worn or damaged, there is a disadvantage that also loses the function.

도 3의 체크밸브(200)는 근래에 알려진 밸브로서, 볼트 머리(211)를 가진 밸브몸체(210)와, 그 내부에 형성하되 테이퍼지지 않은 단턱부(212)와, 상기 단턱부(212)에 접하도록 하되 내환돌기(221)와 외환돌기(222)가 이중으로 형성된 밸브변(220)과, 상기 밸브변(220)의 후방에 탄설시킨 복귀 스프링(230)과, 복귀 스프링(230)의 이탈을 방지하는 스톱퍼(240)로 이루어 진다.The check valve 200 of FIG. 3 is a valve known in recent years, the valve body 210 having a bolt head 211, a stepped portion 212 formed therein but not tapered, and the stepped portion 212. A valve side 220 having a double inner ring protrusion 221 and a foreign exchange protrusion 222, a return spring 230 which is installed on the rear of the valve side 220, and a return spring 230. It is made of a stopper 240 to prevent departure.

그러나 이와 같은 체크밸브(200)에 있어서는 밀착되는 면적이 넓어서 좋기는 하지만 이중의 내환돌기(221) 및 외환돌기(222)중 일부분이 손상 또는 마모될 염려가 많고, 이와 같이 마모나 손상 되었을 경우, 밸브로서의 기능을 즉시 상실하게 되는 단점이 있다.However, in such a check valve 200, although the area that is in close contact is good, there is a high possibility that some of the double inner ring projection 221 and the foreign exchange projections 222 are damaged or worn out, and when worn or damaged in this way, The disadvantage is that it immediately loses its function as a valve.

따라서 본 발명은 상기와 같은 종래의 문제점들을 감안하여 이들의 장점만을 채택하는 새로운 구조의 밸브를 제공하고자 하는 것으로서, 발명의 주된 목적은 밸브 몸체와 밸브변을 새로이 구성하되, 1차적인 접촉부와 2차적인 접촉부를 각각 다른 모양으로 형성하여 어느 한 부분이 손상되더라도 나머지 부분이 밸브로서의 기능을 지속할 수 있도록 하는데 있으며, 더 나가서 밸브의 수명을 연장시킬 수 있도록 하는데 있다.Therefore, the present invention is to provide a valve of a new structure that adopts only their advantages in view of the conventional problems as described above, the main object of the invention is to newly configure the valve body and valve valve, the primary contact portion and 2 The primary contacts are formed in different shapes to allow the remaining parts to continue to function as valves even if one part is damaged, and to further extend the life of the valve.

상기 목적을 달성하기 위한 본 발명의 특징적인 구성은 볼트 머리를 가진 밸브몸체와, 그 내부에 내장할 밸브변과, 상기 밸브변을 받치기 위한 압축 스프링과, 이 스프링의 후방을 받치는 스톱퍼로 구성한 밸브에 있어서, 상기한 밸브몸체는 그 내부 중단에 내측단면부와, 이 내측단면부로부터 시작되는 테이퍼부를 가지도록 형성하고, 상기한 밸브변은 상기 테이퍼부에 접하게 될 반구형 접촉부와, 그 둘레에서 돌출 형성되어 상기 내측단면부에 접하게 될 환테형 접촉부를 가지도록 형성하여 동일하지 않은 면에 각각 접촉되는 이중의 접촉부를 가지도록 하는데 있다.A characteristic configuration of the present invention for achieving the above object comprises a valve body having a bolt head, a valve side to be embedded therein, a compression spring for supporting the valve side, and a stopper for supporting the rear of the spring.

이하 본 발명의 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

도 4는 본 발명의 밸브(300)를 보인 단면도로서, 알터네이터(10)에 일체로 구성된 진공펌프(20)에 조립하여 사용한다.4 is a cross-sectional view showing the valve 300 of the present invention, which is used by assembling the vacuum pump 20 integrally formed with the alternator 10.

이 역시 볼트 머리(311)를 가진 밸브몸체(310)와, 그 내부에 내장할 밸브변(320)과, 상기 밸브변(320)을 받치기 위한 압축 스프링(330)과, 이 스프링의 후방을 받치는 소톱퍼(340)로 구성된다.The valve body 310 also has a bolt head 311, a valve side 320 to be embedded therein, a compression spring 330 for supporting the valve side 320, and a rear of the spring. The support consists of a small topper 340.

이때, 상기한 밸브몸체(310)는 그 내부 중단에 내측단면부(312)와, 이 내측단면부로부터 시작되는 테이퍼부(313)를 가지도록 형성하는 것이 특징이고, 상기한 밸브변(320)은 상기 테이퍼부(313)에 접하게 될 반구형 접촉부(322)와, 그 둘레에서 돌출 형성되어 상기 내측단면부(312)에 접하게 될 환테형 접촉부(321)를 가지도록 형성하는 것이 특징이다.At this time, the valve body 310 is characterized in that it has an inner end portion 312 and the tapered portion 313 starting from the inner end portion at the inner end thereof, the valve side 320 described above. Is characterized in that it is formed to have a hemispherical contact portion 322 to be in contact with the tapered portion 313, and the annular contact portion 321 is formed protruding from the circumference to be in contact with the inner end surface portion 312.

이와 같이 구성된 본 발명의 밸브(300)는 압축스프링(330)의 힘에 의해 전진되면 밸브변(320)의 환테형 접촉부(321)와 내측단면부(312), 그리고 반구형 접촉부(322)와 테이퍼부(313)가 각각 접촉하여 이중의 접촉면을 갖게 된다.When the valve 300 of the present invention configured as described above is advanced by the force of the compression spring 330, the annular contact portion 321, the inner end surface portion 312, and the hemispherical contact portion 322 and the taper of the valve side 320 are tapered. Each of the portions 313 contacts each other to have a double contact surface.

그리고 사실상 엄격히 따지면 상기한 환테형 접촉부(321)와 내측단면부(312)가 근소한 차이로 먼저 접촉하고, 이어서 반구형 접촉부(322)와 테이퍼부(313)가 각각 접촉하도록 하는 것이 바람직하다.In fact, it is preferable that the annular contact portion 321 and the inner end surface portion 312 contact first with a slight difference, and then the hemispherical contact portion 322 and the tapered portion 313 contact each other.

이는 반구형 접촉부(322)와 테이퍼부(313)가 먼저 접촉하게 되면 환테형 접촉부(321)와 내측단면부(312)의 접촉상태가 부실해 질 염려가 있기 때문이다.This is because if the hemispherical contact portion 322 and the tapered portion 313 are in contact first, the contact state between the annular contact portion 321 and the inner end surface 312 may be poor.

상기와 같이 구성된 본 발명의 밸브는 환테형 접촉부(321)와 내측단면부(312)의 1차 접촉상태가 부실해진다 하더라도 테이퍼부(313)에 접하는 반구형 접촉부(322)가 있기 때문에 그 기능을 계속적으로 유지할 수 있다.The valve of the present invention configured as described above has a hemispherical contact portion 322 in contact with the tapered portion 313 even if the primary contact state of the annular contact portion 321 and the inner end surface portion 312 is poor, and thus continues its function. Can be maintained.

또, 상기한 반구형 접촉부(322)에 접하는 테이퍼부(313)의 가공상태가 불완전하여 미세하나마 틈이 발생된다고 하더라도 그보다 먼저 접촉하는 환테형 접촉부(321)와 내측단면부(312)가 있기 때문에 역시 밸브로서의 기능을 유지할 수 있게 되는 것이다.In addition, even if the processing state of the tapered portion 313 in contact with the hemispherical contact portion 322 is incomplete, even if a small gap is generated, the annular contact portion 321 and the inner end surface portion 312 that contact the earliest contact are also present. It is possible to maintain the function as a valve.

위에서 상세히 설명한 바와 같은 본 발명의 밸브는 밸브 몸체와 밸브변을 새로이 구성하되, 1차적인 접촉부와 2차적인 접촉부를 각각 다른 모양으로 형성하였기 때문에 어느 한 부분의 기능이 약간 손상 되더라도 나머지 부분이 밸브로서의 기능을 지속하게 된다.As described in detail above, the valve of the present invention newly configures the valve body and the valve side, but since the primary contact portion and the secondary contact portion are formed in different shapes, respectively, the remaining portion of the valve may be damaged even if the function of one portion is slightly damaged. Will continue to function as

따라서 종래의 밸브와 달리 일 부분적인 손상이나, 마모로 인한 틈새가 발생한다고 하더라도 밸브의 기능을 그대로 발휘하기 때문에 진공펌프의 수명을 연장시킬 수 있는 장점이 있다.Therefore, unlike a conventional valve, even if a partial damage or a gap occurs due to wear, since the valve functions as it is, there is an advantage of extending the life of the vacuum pump.
