Description
본 고안은 터보차저 엔진의 과급압 조절장치에 관한 것이다.The present invention relates to a boost pressure regulating device of a turbocharger engine.
종래 터보차저 엔진은 도 2 에 도시하는 것과같이 액츄에이터(14)를 이용하여 터보차저(11)에 의한 과급압을 제어하고 있다. 그러나 액츄에이터(14)가 고장시 서지탱크(12)측에 과도한 압을 배출하기 위하여 별도의 안전 밸브(13)를 마련하고 있어 장치의 구조가 복잡해지고 설치비용이 증대되는 문제점이 있게된다.The conventional turbocharger engine controls the boost pressure by the turbocharger 11 using the actuator 14, as shown in FIG. However, since the actuator 14 is provided with a separate safety valve 13 in order to discharge excessive pressure on the surge tank 12 side when the failure occurs, there is a problem that the structure of the device is complicated and the installation cost is increased.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 안전밸브 기능을 액츄에이터에 통합하여 구조를 단순화한 터보차저 엔진의 과급압 조절장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and its object is to provide a boost pressure regulating device for a turbocharged engine with a simplified structure by integrating a safety valve function into an actuator.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 터보차저 엔진의 과급압 조절장치를 나타내는 도면으로 도면에 있어서 부호 1은 터보차저이며, 부호 2는 터보차저(1)의 과급압을 조절하기 위해 서지탱크(10)와의 사이를 연결하는 관로(3)상에 마련되는 액츄에이터이다.1 is a view showing a boost pressure regulating device of a turbocharger engine according to the present invention. In the drawing, reference numeral 1 denotes a turbocharger, and reference numeral 2 indicates a surge tank 10 to adjust the boost pressure of the turbocharger 1. It is an actuator provided on the pipeline 3 which connects between them.
상기 액츄에이터(2)는 실린더(4)와, 터보차저의 압력에 의해 리턴 스프링(5)을 압축하면서 이동하게 되는 피스톤(6)과, 피스톤(6)의 몸체를 축과 직각방향으로 관통하는 바이패스공(7)과 상기 피스톤(6)이 터보차저(1)측의 기준치 이상의 압력 증가로 일정거리 만큼 리턴 스프링(5)을 압축하면서 이동하였을 때 상기 바이패스공(7)과 연통하는 구멍(8)(9)과로 구성되며, 상기 구멍(8)(9)은 실린더(4)의 양측 벽면에 천공되어 진다.The actuator (2) is a cylinder (4), a piston (6) which moves while compressing the return spring (5) by the pressure of the turbocharger, and the bypass through the body of the piston (6) at right angles to the shaft A hole communicating with the bypass hole 7 when the pass hole 7 and the piston 6 move while compressing the return spring 5 by a predetermined distance due to an increase in pressure above the reference value on the turbocharger 1 side ( 8) and (9), the holes (8) and (9) are drilled on both side walls of the cylinder (4).
그리고 상기 구멍(8)(9)의 일측(8)은 서지탱크(10)측에 접속되고 타측(9)은 대기에 개방되어 있다. 여기서 미설명 부호 11은 피스톤 로드이다.One side 8 of the holes 8, 9 is connected to the surge tank 10 side and the other side 9 is open to the atmosphere. Reference numeral 11 here is a piston rod.
이에따라 터보차처(1)의 과급압이 기준치 이상으로 높아지게 되면 피스톤(6)이 이동하게 되며 바이패스공(7)과 구멍(8)(9)이 일직선상으로 연통되어지면 서지탱크(10)측의 공기가 일직선상으로 연통된 구멍(8), 바이패스공(7) 및 구멍(9)을 통해 외부로 방출되어져 과도한 압력에 의한 장치의 손상을 방지하게 된다.Accordingly, when the boost pressure of the turbocharger 1 becomes higher than the reference value, the piston 6 moves, and when the bypass hole 7 and the holes 8, 9 communicate in a straight line, the surge tank 10 side Air is discharged to the outside through the straight line communicating holes 8, bypass holes 7 and holes 9 to prevent damage to the device due to excessive pressure.
이상과 같은 고안에 의한 터보차저 엔진의 과급압 조절장치에 의하면 과급압 조절을 위한 액츄에이터에 릴리프 밸브 기능을 갖도록 구조 변경하므로서 별도로 서지탱크 측에 설치되던 릴리프 밸브를 삭제할 수 있어 구조가 단순화되고 원가를 절감하게 되는 효과가 있게된다.According to the turbocharger's boost pressure control device, the structure of the turbocharger engine has a relief valve function so that the relief valve installed on the side of the surge tank can be deleted to simplify the structure and reduce the cost. The savings are effective.
