본 발명은 오일리저버에 관한 것으로, 보다 상세하게는 일방향으로 체결되면서 내부의 공기 통로를 통한 오일 누출을 방지 한 오일리저버의 주입구 결합 구조에 관한 것이다.The present invention relates to an oil reservoir, and more particularly, to an inlet coupling structure of an oil reservoir which is fastened in one direction and prevents oil leakage through an internal air passage.

일반적으로 주행중인 차량을 정지시키는 브레이크 시스템은, 운전자의 조작력을 받아들이는 브레이크페달의 답력에 의해 부스터에 연결되어 압력을 발생시키는 마스터실린더로부터 발생된 유압에 의해 제동력을 발생시겨 주게 된다.In general, a brake system for stopping a vehicle that is driving generates braking force by hydraulic pressure generated from a master cylinder that generates pressure by being connected to a booster by a foot pedal of a brake pedal that receives driver's operating force.

이와 같은 브레이크 시스템은 오일을 이용하여 마스터실린더에서 유압을 발생시키도록 통상, 브레이크 오일을 담은 오일리저버(Oil Reserver)로부터 마스터실린더로 오일을 공급하게 된다.Such a brake system typically supplies oil from the oil reservoir containing the brake oil to the master cylinder to generate hydraulic pressure in the master cylinder using the oil.

이때, 상기 오일리저버는 기밀을 유지함은 물론 내부의 공기를 외부로 배출할 수 있는 공기 통로를 확보해야 만 되고, 이에 따라 오일 리저버의 주입구 부위는 캡(Cap)체결 시 누유를 차단하면서 동시에 공기 통로를 형성하여야 만 함은 물론이다.At this time, the oil reservoir must maintain an airtight, as well as to secure an air passage for discharging the internal air to the outside, so that the inlet portion of the oil reservoir at the same time blocking the oil leakage when the cap (Cap) fastening Of course it must form.

그러나, 이와 같은 오일 리저버의 캡 체결부위에 대한 누유 차단과 공기통로 확보라는 서로 상반된 이중 기능을 만족하는 것이 상당히 어려운 문제인데 즉, 오일 리저버의 내부에서 캡 체결 부위 쪽으로 공기 통로가 형성되는 특성 상, 급 제동 시와 같이 찰랑대면서 위로 유입되는 오일이 공기 통로를 통해 외부로 누출되는 현상이 빈번하고 특히, 오일 리저버가 기울어지는 경우에는 내부 오일이 캡 체결 부위까지 위치되어져 외부 누출이 더욱 심해지는 현상이 있게 됨은 물론이다.However, it is quite difficult to satisfy the mutually opposite dual functions of oil leakage blocking and air passage securing to the cap fastening portion of the oil reservoir, that is, the air passage is formed toward the cap fastening portion in the oil reservoir. Frequent leakage of oil flowing through the air passage through the air passage as in case of rapid braking, especially when the oil reservoir is inclined, the internal oil is located up to the cap fastening portion and the external leakage is more severe. Of course it is.

이는, 상기 캡 체결부위가 마개인 캡(Cap)과 오일 넘침을 차단하는 배플(Baffle) 및 오일 주입구간의 구조적인 형상을 통해 상호 이루어지지만, 이들 간의 구조적 특성이 단순히 체결 측면만을 고려함에 따라 작업자의 조립 상태에 따라 공기 통로의 위치가 변화되는 즉, 오일 주입구 쪽으로 오일이 위치될 때 공기 통로를 타고 캡과 오일주입구사이의 틈을 통해 외부로 배출될 수 있는 현상이 있게 된다.This is done through the structural shape of the cap cap and the baffle and the oil injection section for blocking the overflow of the cap cap, but the structural characteristics between them simply consider the fastening side of the operator The position of the air passage is changed according to the assembly state, that is, when the oil is positioned toward the oil inlet, there is a phenomenon that the air can be discharged to the outside through the gap between the cap and the oil inlet.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 오일 리저버의 주입구인 캡 체결부위를 이루는 오일 주입구와 캡 및 배플간에 일 방향으로 만 조립될 수 있도록 하면서, 배플에 형성된 공기 통로를 가려주어 급정거 시와 같이 오일이 오일 주입구 쪽으로 유입되더라도 오일의 누출을 차단할 수 있도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned point, while allowing the air inlet formed in the baffle to be assembled between the oil inlet and the cap and the baffle forming the cap fastening portion, which is the inlet of the oil reservoir, in one direction. The purpose is to prevent the oil from leaking even if oil is introduced into the oil inlet as in a sudden stop.

상기와 같은 목적을 달성하기 위한 본 발명은, 오일 리저버가 내부의 공기를 배출하면서 유동에 의한 오일의 넘침을 차단하는 배플이 나사 체결된 오일주입구와, 상기 오일주입구의 끝단부에 형성된 주입구결합단에 체결되는 캡 및, 상기 캡이 오일주입구에 체결됨에 따라 주입구결합단과 배플간에 서로 결합되는 상대결합형성수단으로 이루어지되, The present invention for achieving the above object, an oil inlet screw-fastened baffle for blocking the overflow of oil by flow while the oil reservoir discharges the inside, and the inlet coupling end formed at the end of the oil inlet Cap is fastened to, and as the cap is fastened to the oil inlet is made of a relative coupling forming means coupled to each other between the inlet coupling end and the baffle

이하 본 발명의 작용을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 오일리저버는 오일주입구(1)와 캡(6)간의 결합 구조인 상대결합형성수단에 의해 캡(6)이 일 방향으로 만 체결될 수 있도록 하면서 동시에, 오일주입구(1)와 배플(3) 및 캡(6)간의 결합 구조인 상대결합형성수단에 의해 오버플로우 시 내부의 오일이 오일주입구(1)를 통한 캡(6)외부로의 누출을 차단할 수 있도록 작용하게 된다.The oil reservoir of the present invention allows the cap 6 to be fastened only in one direction by a relative coupling forming means, which is a coupling structure between the oil inlet 1 and the cap 6, and at the same time, the oil inlet 1 and the baffle ( 3) by the relative coupling forming means, which is a coupling structure between the cap 6, the internal oil acts to prevent leakage to the outside of the cap 6 through the oil inlet 1 during overflow.

즉, 오일리저버의 오일주입구(1)에 배플(3)의 나사체결바디(4)를 체결한 후, 상기 오일주입구(1)의 주입구결합단(2)으로 캡(6)을 체결하게 되면, 상기 캡(6)의 내면부(6b)에서 배플(3)이 위치 고정됨과 동시에 캡(6)의 일 방향 회전에 의해 캡(6)이 오일주입구(1)를 밀폐시켜 주게 된다.That is, when the screw fastening body 4 of the baffle 3 is fastened to the oil inlet 1 of the oil reservoir, and then the cap 6 is fastened to the inlet coupling end 2 of the oil inlet 1, The baffle 3 is fixed at the inner surface portion 6b of the cap 6, and the cap 6 seals the oil inlet 1 by one direction rotation of the cap 6.

이와 같이, 오일주입구(1)의 주입구결합단(2)과 배플(3) 및 캡(6)간에 서로 결합되고 나면, 오일리저버를 경사(약 42°이며 이는 시험 시 요구 경사각임)시키더라도 내부 오일이 캡(6)을 통해 외부로 누출되지 않게 된다. As such, after the inlet coupling end 2 of the oil inlet 1 and the baffle 3 and the cap 6 are coupled to each other, the oil reservoir is inclined (approximately 42 °, which is a required inclination angle during the test). The oil does not leak out through the cap 6.

이에 대해 먼저 캡(6)이 일 방향으로 만 체결되도록 하는 작용은, 오일리저버의 오일주입구(1)의 주입구결합단(2)과 캡(6)간의 결합 구조인 일방향차단수단을 통해 이루어지게 되는데 즉, 도 1에 도시된 바와 같이 상기 오일주입구(1)의 주입구결합단(2)에 형성된 일방향체결단을 이루는 제1·2·3걸림단(2a,2b,2c)으로 배플(3)의 차단플랜지(5)가 안착되도록 나사체결바디(4)를 체결한다.On the contrary, the cap 6 is fastened only in one direction. The cap 6 is formed through the one-way blocking means, which is a coupling structure between the inlet coupling end 2 and the cap 6 of the oil inlet 1 of the oil reservoir. That is, as shown in Figure 1 of the baffle (3) to the first, second, third engaging end (2a, 2b, 2c) forming a one-way fastening end formed in the inlet coupling end (2) of the oil inlet (1) Tighten the screwing body (4) so that the blocking flange (5) is seated.

이어, 상기 오일주입구(1)의 주입구결합단(2)으로 캡(6)을 누르면서 일 방향으로 회전하면, 상기 캡(6)의 회전 완료 후 결합보스단의 제1결합보스(7a)가 주입구결합단(2)에 형성된 일방향체결단의 제2·3걸림단(2b,2c)사이에 형성된 공간으로 위치되고, 상기 결합보스단의 제2·3결합보스(7b,7c)는 각각 일방향체결단의 제1걸림단(2a)과 제2·3걸림단(2b,2c) 사이로 위치되어진다.Subsequently, when the cap 6 is rotated in one direction while pressing the cap 6 into the inlet coupling end 2 of the oil inlet 1, the first coupling boss 7a of the coupling boss end is the inlet after completion of the rotation of the cap 6. Located in the space formed between the second and third engaging end (2b, 2c) of the one-way fastening end formed in the coupling end (2), the second and third coupling bosses (7b, 7c) of the coupling boss stage are respectively one-way fastening It is positioned between the first engaging end 2a of the stage and the second and third engaging ends 2b and 2c.

이와 같이, 상기 캡(6)과 주입구결합단(2)의 결합에 따라 제1·2·3결합보스(7a,7b,7c)와 제1·2·3걸림단(2a,2b,2c)사이에 형성된 공간이 모두 가려지게 되면, 상기 주입구결합단(2)의 상면으로 위치되는 배플(3)의 차단플랜지(5)저면에 형성된 에어채널(5a)이 가려진 상태로 되며, 이때 상기 에어채널(5a)은 그 홈을 통해 공기의 순환이 이루어짐은 물론이다.As such, the first, second and third coupling bosses 7a, 7b, and 7c and the first, second and third locking ends 2a, 2b, and 2c are coupled to each other by the cap 6 and the injection hole coupling end 2. When all the spaces formed therebetween are covered, the air channel 5a formed at the bottom of the blocking flange 5 of the baffle 3 positioned on the upper surface of the inlet coupling end 2 is covered with the air channel. Of course, 5a is air circulation through the groove.

즉, 상기 주입구결합단(2)과 배플(3) 및 캡(6)간에 서로 위치되면서 이루어지는 결합 구조로 인해, 오일이 오일주입구(1)쪽으로 쏠리도록 오일리저버를 42°경사 시켜 주더라도 배플(3)의 차단플랜지(5)저면에 형성된 에어채널(5a)이 가려진 상태를 유지하므로, 상기 에어채널(5a)쪽으로 흐르는 오일이 주입구결합단(2)의 일방향체결단과 캡(6)의 결합보스단에 의해 대부분 차단되어 캡(6)을 통한 외부 유출이 거의 발생하지 않게 된다. That is, due to the coupling structure formed while being positioned between the inlet coupling end 2 and the baffle 3 and the cap 6, even if the oil reservoir is inclined to the oil inlet 1 by 42 ° baffle ( Since the air channel 5a formed on the bottom surface of the blocking flange 5 of FIG. 3 is covered, the oil flowing toward the air channel 5a flows toward the one-way fastening end of the inlet coupling end 2 and the cap 6. Most are blocked by the stage so that the outflow through the cap 6 hardly occurs.

한편, 상기 캡(6)을 오일주입구(1)로 체결하게 됨에 따라 캡(6)과 배플(3)도 위치구속수단을 매개로 서로간에 결합이 이루어지는데 이는, 도 2에 도시된 바와 같이 상기 캡(6)을 오일주입구(1)의 주입구결합단(2)에 결합하면, 상기 캡(6)의 돌출된 메일구속단이 배플(3)을 이루는 차단플랜지(5)의 위치구속홀(4a)에 형성된 피메일구속단으로 삽입되면서 캡(6)을 구속해주게 된다. On the other hand, as the cap 6 is fastened to the oil inlet 1, the cap 6 and the baffle 3 are also coupled to each other through the position restraining means, as shown in FIG. 2. When the cap 6 is coupled to the inlet coupling end 2 of the oil inlet 1, the position restricting hole 4a of the blocking flange 5 in which the protruding mail binding end of the cap 6 forms the baffle 3 is formed. The cap (6) is restrained while being inserted into the female binding end formed in the).

즉, 상기 캡(6)의 메일구속단을 이루는 제1위치구속보스(8a)를 배플(3)의 피메일구속단을 이루는 제1구속면(4b)으로 위치시키면, 상기 메일구속단의 제2·3위치구속보스(8b,8c)가 피메일구속단을 이루는 제2·3구속면(4c,4d)으로 안착되고 이때, 상기 피메일구속단을 이루는 제4구속면(4e)은 상기 제2·3위치구속보스(8b,8c) 사이로 삽입되고, 이에 따라 상기 배플(3)과 캡(6)은 서로간을 구속하면서 체결되어진다.That is, when the first position binding boss 8a constituting the mail restraint end of the cap 6 is positioned on the first restraining surface 4b constituting the female restraint end of the baffle 3, The 2nd and 3rd position restraint bosses 8b and 8c are seated by the 2nd and 3rd restraint surfaces 4c and 4d which form a female restraint stage, At this time, the 4th restraint surface 4e which comprises the said female restraint stage is the said The baffle 3 and the cap 6 are fastened while being restrained from each other by being inserted between the second and third position restriction bosses 8b and 8c.

이상 설명한 바와 같이 본 발명에 의하면, 오일 리저버내 공기를 배출하도록 오일 주입구에 결합된 배플의 저면으로 형성된 배출통로의 부위가 서로 결합되는 캡과 오일주입구의 일 방향 회전에 의한 결합 구조를 통해 가려지도록 해, 오일 리저버의 경사나 외부에 의한 유동으로 인해 오일 주입구쪽으로 넘치는 오일이 공기의 배출 통로를 통해 외부로 누출되지 않는 효과가 있게 된다.As described above, according to the present invention, the portion of the discharge passage formed by the bottom surface of the baffle coupled to the oil inlet to discharge the air in the oil reservoir is covered by the coupling structure by the one-way rotation of the cap and the oil inlet coupled to each other. Therefore, due to the inclination of the oil reservoir or the flow by the outside, the oil overflowing toward the oil inlet does not leak out through the air discharge passage.
