본 고안은 자동차용 제동제어장치에서 사용되는 감압조정밸브에 관한 것으로서, 특히 유체의 입력과 출력의 압력분배를 조절하는 소켓형 감압 조정밸브에 관한 것이다.The present invention relates to a pressure reducing valve used in a braking control device for automobiles, and more particularly to a socket-type pressure reducing valve for controlling the pressure distribution of the input and output of the fluid.

종래의 감압조정밸브는 제1도 및 제2도에서 도시한 바와 같이 브레이크 페달(3)에 답력(力)을 가할시는 마스타 실린더(4)에서 발생된 유압이 파이프라인(5)을 통해 밸브체하우징(1)의 밸브체입구(11A)에 전달되고, 상기 밸브체하우징(1)에 내장된 스프링(26A)의 탄발력에 의해 밀착된 피스톤(2)과 밸브실(Valve Seal)(14A)사이의 틈새(Gap)(G)을 통하여 휠 실린더(6)의 피스톤(6A)에 압력이 전달되어 브레이크슈(7)를 드럼(도면중 미도시)에 밀착시키면서 제동력을 발생시키게 되며, 상기한 상태로 브레이크 페달(3)에 답력에 계속유지시키면 입력과 출력의 힘이 커지고 적어짐에 따라 피스톤(2)이 상하로 왕복운동을 하면서 피스톤(2)의 헤드가밸브실(14A)과 접촉 또는 비접촉하여 통로를 개폐함으로써, 감압조절기능을 수행하는 구성으로 되어 있으나, 이는 감압조정 밸브의 조립체(93×58×38)가 크기 때문에 재료가 많이 필요하여 재료비가 상승케됨과 동시에 가공시간이 길어짐으로 인하여 제품단가가 부대적으로 높아지는 문제점이 있었다.Conventional pressure reducing valves are provided with the brake pedal 3 as shown in FIGS. 1 and 2. Iii), the hydraulic pressure generated in the master cylinder 4 is transmitted to the valve inlet 11A of the valve body housing 1 through the pipeline 5, and built into the valve body housing 1; Pressure is transmitted to the piston 6A of the wheel cylinder 6 through a gap G between the piston 2 and the valve seal 14A that are in close contact with the spring force of the spring 26A. To generate the braking force by closely contacting the brake shoe 7 to the drum (not shown in the drawing) .If the brake pedal 3 is kept in the pedaling force in the above state, the input and output forces increase and decrease the piston ( 2) the reciprocating movement up and down, the head of the piston (2) is in contact with or non-contact with the valve chamber 14A to open and close the passage, it is configured to perform the pressure-reducing control function, this is the assembly of the pressure-reducing valve assembly (93) Because of the large size of × 58 × 38), a lot of materials are required, resulting in an increase in material costs. Disclosure simplified due to the longer there is a problem in the product price increased by enemy forces.

또한, 제2도에서 나타낸 바와 같이 라인이 꺽기는 지점, 즉 절점(折点)이 금속재인 피스톤(2)과 고무재인 밸브실(14A)과의 접촉에 의해 밸브실(14A)의 눌림에 의한 영향으로 완전밀착에 미소시간이 요구되고, 고무의 물성 및 다품(각파트)상태에 따라 피스톤(2)이 편위하게 접촉되면서 절점효과가 불량해짐으로 인하여 밸브성능의 가장큰 결함의 요소인 오버슈트(Over Shooot)현상 및 내구력이 약해지는 등의 문재점이 있었다.In addition, as shown in FIG. 2, the point where the line breaks, that is, the node is contacted by the piston 2 made of metal and the valve chamber 14A made of rubber, is pressed by the valve chamber 14A. Overshoot, which is a factor of the biggest defect of valve performance, is required due to the effect that micro time is required for perfect adhesion, and the piston 2 is unevenly contacted according to the physical properties of rubber and various parts (angular parts). (Over Shooot) There were problems such as weakening and durability.

이와 같이 구성된 본 고안의 작용효과를 상세히 설명한다.The effect of the present invention configured as described above will be described in detail.

먼저, 번 고안의 제3도와 제4도에서 도시한 바와 같이 브레이크페달(3)에 답력을 가할시는 마스타실린더(4)의 액압이 프아프라인(5)을 통하여 밸브하우징(10)의 제1공간부(11)로 전달되고, 이 액압은 메인스프링(26)의 탄발력에 의해 피스톤(20)의 헤드(21)가 엔드플러그(30)의 가이드홈(33)으로 밀착됨에 따라 밸브하우징(10)의 제1공간부(11)와 피스톤(20)의 밸브경사면(23a), 관통홀(23,34) 및 파이프라인(5)을 통하여 휠실린더(6)의 피스톤(^A)을 작동시키면서 브레이크 슈(7)가 벌려짐에 의해 브레이키슈(7)가 드럼(도면중 미도시)의 내면을 밀착시키므로 인하여 제동력이 발생케된다.(제3도의 실선참조)First, as shown in FIGS. 3 and 4, the hydraulic pressure of the master cylinder 4 is applied to the valve housing 10 through the puff line 5 when the pedal pedal 3 is applied to the pedal pedal 3. It is transmitted to the one space portion 11, the hydraulic pressure is the valve housing as the head 21 of the piston 20 is in close contact with the guide groove 33 of the end plug 30 by the elastic force of the main spring 26 The piston (^ A) of the wheel cylinder 6 is moved through the first space 11 of 10 and the valve inclined surface 23a of the piston 20, the through holes 23, 34, and the pipeline 5, respectively. As the brake shoe 7 opens while being operated, the braking shoe 7 comes into close contact with the inner surface of the drum (not shown in the figure), thereby causing a braking force (see solid line in FIG. 3).

여기서, 상기한 상태로 브레이크페달(3)에 답력을 계속유지시키게되면, 액압에 의해 드럼(도면중 미도시)에 압착된 브레이크슈(7)는 액압이 메인스프링(26)의 탄발력과 입력 액압보다 커지면 피스톤(20)이 밸브하우징(10)의 관통홀(11), 컵실(14)의 내면 및 엔드플러그(30)의 가이드홈(33)을 따라 우측에서 좌측으로 미끄럼이동을 하면서 피스톤(20)의 밸브경사면(23a)이 밸브포핏(15)의 만곡돌기(15a)에 맞닿으면서 입력이 순간적으로 차단되고, 마스타실린더(4)측의 액압이 증가하여 메인스프링(26)의 탄발력과 입력 액압보다 적어지면 피스톤(20)이 밸브하우징(10)의 관통홀(11), 컵실(14)의 내면 및 엔드플러그(30)의 가이드홈(33)을 따라 좌측에서 우측으로 미끄럼운동을 하면서 밸브포핏(15)의 만곡돌기(15a)에 밀폐되어 있던 피스톤(20)의 밸브경사면(23a)이 떨어지면서 열리는 밸브의 개폐작동을 반복하면서 브레이크액압을 제어하므로 제5도에서 도시한 바와같이 오버슈트현상을 방지하게 됨과 동시에 피스톤(20)의 밸브하우징(10)의 관통홀(11), 컵실(14)의 내면 및 엔드플러그(30)의 가이드홈(33)을 따라 좌우측으로 편위 없이 동일하게 이동하기 때문에 절점효과를 향상시키면서 엔드플러그(30)의 내구력을 향상시키게 된다.In this case, when the pedaling force is continuously maintained in the brake pedal 3 in the above state, the brake shoe 7 compressed to the drum (not shown in the drawing) by the hydraulic pressure has the hydraulic pressure and the input force of the main spring 26. When the hydraulic pressure is greater than the hydraulic pressure, the piston 20 slides from right to left along the through hole 11 of the valve housing 10, the inner surface of the cup chamber 14, and the guide groove 33 of the end plug 30. While the valve inclined surface 23a of 20 is in contact with the curved protrusion 15a of the valve poppet 15, the input is momentarily interrupted, and the hydraulic pressure on the master cylinder 4 side increases, so that the elastic force of the main spring 26 is increased. When less than the input hydraulic pressure, the piston 20 slides from left to right along the through hole 11 of the valve housing 10, the inner surface of the cup chamber 14, and the guide groove 33 of the end plug 30. While the valve inclined surface 23a of the piston 20, which is closed on the curved protrusion 15a of the valve poppet 15, falls, Lee controls the brake hydraulic pressure by repeating the opening and closing operation of the valve, thereby preventing overshoot as shown in FIG. 5, and at the same time, the through hole 11 and the cup chamber 14 of the valve housing 10 of the piston 20. Since the same movement to the left and right sides along the guide groove 33 of the inner surface and the end plug (30) without any deviation is to improve the durability of the end plug 30 while improving the nodal effect.

그리고, 브레이크페달(3)에 가해진 답력을 해제시는 입력 액압이 해제됨에 따라 휠실린더(6)의 내측으르 들어가면서 브레이크슈(7)를 밀착한 액압은 순간적으로 마스타 실린더(4)의 저장탱크(40)로 원위치되어 제동력이 풀리게 된다.Then, as the input hydraulic pressure is released when the pedal force applied to the brake pedal 3 is released, the hydraulic pressure in which the brake shoe 7 comes into close contact with the brake shoe 7 while entering the inside of the wheel cylinder 6 is instantaneously stored in the storage tank of the master cylinder 4. 40) is released and the braking force is released.

이와 같이 된 본 고안은 종래의 감압조절밸브와는 달리, 유체의 입력과 출력의 압력분배를 조절하는 감압조정밸브를 간단한 구조로하여 최소한 적게 제작함에 따라 제품의 가공시간 절감 및 재료비 절감에 의해 제품을 저렴한 가격에 제작케되는 효과가 있으며, 또한 오버슈트현상방지 및 엔드플러그의 내구력을 향상시키는 효과도 있는 고안이다.Unlike the conventional pressure reducing valve, the present invention has a simple structure for controlling the pressure distribution of the input and output of the fluid. It has the effect of being produced at a low price, and also has the effect of preventing overshoot phenomenon and improving endurance durability of the end plug.
