즉, 엔진에 연료량을 조절공급하는 컨트롤랙(1)과 엔진의 회전속도에 따라서 확개하는 플라이웨이트(2)와 이 플라이 웨이트(2)의 확개정도에 따라 요동하는 텐센레버(3)와 가이드레버(4)를 구비하고, 상기 가이드레버(4)와 컨트롤랙(1)과의 사이에 컨트롤레버(5)를 연결하여 요동이 자유롭도록 연결된 플로우팅레버(6)의 사이에 스낵클(7)과 스낵클(8)이 서로 요동자유롭게 연결된 종래의 원심조속기에 있어서, 상기 텐션레버(3)의 상부에 스프링어셈블리(10)를 장착하여 엔진시동시의 시동연료증량 치를 규정하는 컨트롤랙(1)에 접속된 센서레버(9)는 엔진시동시에 컨트롤랙(1)이 시동연료증량 위치까지 변위할 수 있게 하되, 상기 텐션레버(3)의 요동각에 따라 상기 스프링어셈블리(10)가 센서레버(9)를 가압하여 강제적으로 회동변위케하고, 엔진시동시에 컨트롤레버(5)를 전부하상태에 두면 스낵클(7)과 스택클(8)이 서로 떨어져 있어 가이드레버(4) 및 텐션레버(3)의 요동운동이 컨트롤랙(1)의 움직임에 영향을 주지 않게 되므로 연료증량을 기할 수 있도록 상기 컨트롤랙(1)의 끝단에 컨트롤랙 리미터(27)을 부착한 것으로서, 미설명부호 12,13,14,15,16,17 및 18은 각각 캠축, 슬리이브, 토션스프링, 스포팅레버, 볼조인트, 스타트스프링 및 가바나 스프링으로서 종래의 원심조속기와 동일하게 구성되어있다.That is, the control rack (1) for regulating the amount of fuel supplied to the engine, the flyweight (2) to expand in accordance with the rotational speed of the engine and the tensen lever (3) and the guide swinging in accordance with the expansion degree of the flyweight (2) It is provided with a lever (4), the control lever (5) between the guide lever (4) and the control rack (1) by connecting a control lever (5) between the floating lever (6) connected to the swing freely (7) In the conventional centrifugal governor, which is connected freely to each other and the snack (8), the control rack (1) defining the starting fuel increase value at the time of engine startup by mounting the spring assembly (10) on the upper part of the tension lever (1) The sensor lever 9 connected to) enables the control rack 1 to be displaced to the starting fuel increase position at the time of engine start, and the spring assembly 10 is connected to the sensor lever according to the swing angle of the tension lever 3. (9) Pressurized to force rotational displacement and control at engine start When the lever 5 is placed at full load, the snack 7 and the stack 8 are separated from each other, so that the swinging motion of the guide lever 4 and the tension lever 3 affects the movement of the control rack 1. Since the control rack limiter 27 is attached to the end of the control rack 1 so as to increase fuel consumption, reference numerals 12, 13, 14, 15, 16, 17 and 18 are camshafts and slits, respectively. Eve, torsion spring, spotting lever, ball joint, start spring and gabbana spring are configured in the same way as the conventional centrifugal governor.

상기와 같이 구성된 본 고안의 작용효과에 대하여 종래의 상기한 원심조족기와 병행하여 상세히 설명하면 다음과 같다.If described in detail in parallel with the above-described centrifugal group with respect to the effect of the present invention configured as described above are as follows.

즉, 엔진이 시동되어졌을때 제4도에 도시한 바와 같이 엔진시동에 컨트롤레버(5)를 전부하상태에 두면 컨트롤 랙(1)은 스넥클(7)(8)과 플로우팅레버(6)의 회전에 의해 연료 증가방향으로 움직인다.That is, when the engine is started, as shown in FIG. 4, when the control lever 5 is in the full load state at engine start, the control rack 1 is connected to the snaple 7 and 8 and the floating lever 6; ), It moves in the direction of fuel increase.

이때 스낵클(7)과 스낵클(8)은 서로 떨어져있고, 컨트롤랙(1)의 이송량은 컨트롤랙 리미터(11)에 의해 조종 되어진다.At this time, the snack (7) and the snack 8 is separated from each other, the feed amount of the control rack (1) is controlled by the control rack limiter (11).

그리고 엔진이 아이들링일 경우 캠축(12)이 회전에 의해 플라이웨이트(2)는 슬리이브(13)를 밀어줌으로써 텐션레버(3)를 회전시키고 토션스프링(14)에 의해 가이드레버(4)도 회전운동을 한다.When the engine is idling, the camshaft 12 rotates the flyweight 2 by rotating the tension lever 3 by pushing the sleeve 13 and the guide lever 4 also rotates by the torsion spring 14. work out.

이때 스낵클(7)과 스낵클(8)은 접속되어 연결된 상태여서 가이드레버(4)는 플로우팅레버(6)를 회전시켜 볼조인트(16)에 연결된 스포팅레버(15)에 의해 컨트롤랙(1)을 움직여 원하는 성능을 얻을 수 있다.At this time, the snack (7) and the snack (8) is in a connected state and the guide lever (4) by rotating the floating lever 6 by the spotting lever 15 connected to the ball joint (16) control rack ( Move 1) to get the desired performance.

또한, 엔진이 전부하일경우 상기와 같은 스낵클(7)과 스낵클(8)이 떨어져 있으므로 가이드레버(4)의 운동에 의한 움직임은 스포팅레버(15)에 영향을 주지 않는다.In addition, when the engine is full load, since the above-mentioned snack 7 and the snack 8 are separated, the movement by the movement of the guide lever 4 does not affect the spotting lever 15.

따라서 텐션레버(3)의 회전에 의해 스프링 어샘블리(10)가 작동되는바, 스프링어셈블리(10)와 스타트스프링(17)의 힘 균형관계에 의해 센서레버(9)가 움직임에 따라 컨트롤 랙(1)을 움직여 원하는 성능을 얻을 수 있다.Therefore, the spring assembly 10 is operated by the rotation of the tension lever 3, and according to the force balance relationship between the spring assembly 10 and the start spring 17, the control lever 9 moves according to the control rack ( Move 1) to get the desired performance.

제5도에 도시한 것은 엔진이 무부하시 최고 회전수에 도달할 무렵을 나타낸 것으로서, 스낵클(7)(8)이 서로 접속되어 연결된 만큼 가이드레버(4)가 기울어지면 텐션레버(3)의 가이드레버(4)가 가바나스프링(18)을 이기고 기울어져 플로우팅레버(6)와 스포팅레버(15)를 거쳐 컨트롤랙(1)을 연료감소방향으로 움직여준다.FIG. 5 shows the time when the engine reaches the maximum rotation speed when the engine is no load. When the guide lever 4 is inclined as much as the snacks 7 and 8 are connected to each other, the tension lever 3 The guide lever 4 is inclined to overcome the gabbana spring 18 to move the control rack 1 in the direction of fuel reduction through the floating lever 6 and the spotting lever 15.

상술한 바와 같이 본 고안에 의하면, 엔진시동시에 센서레버(9)와 스프링 어셈블리(10)는 서로 작동치않고 스낵클(7)과 스낵클(8)이 서로 떨어져 있어 가이드레버(4) 및 텐션레버(3)의 요동운동은 컨트롤 랙(1)의 움직임에 영향을 주지 않으므로 컨트롤랙(1)의 끝단에 컨트롤랙 리미터(11)를 부착시켜 엔진시동시에 연료증량을 기할 수 있는 유용한 고안인 것이다.As described above, according to the present invention, the sensor lever 9 and the spring assembly 10 do not operate with each other when the engine is started, and the snack lever 7 and the snack 8 are separated from each other so that the guide lever 4 and the tension are separated from each other. Since the swinging motion of the lever 3 does not affect the movement of the control rack 1, the control rack limiter 11 is attached to the end of the control rack 1 so as to increase the fuel during engine start-up. .
