Description

연료공급장치Fuel supply

본 고안은 연료공급장치에 관한 것으로, 특히 형상기억합금을 이용한 연료공급장치에 관한 것이다.The present invention relates to a fuel supply device, and more particularly to a fuel supply device using a shape memory alloy.

When the fuel is supplied and the power is shorted and the magnetic field is removed, the valve 4 is moved downward by the restoring force of the spring 7 disposed on the upper surface of the head 4 so that the flow path is closed by the stem 3 so that the fuel is closed. Supply is cut off.

그러나, 상기와 같은 솔레노이드방식의 연료공급장치는 솔레노이드코일(6)이 매설된 블럭(8)을 장착함에 따른 제조비용이 증대되는 단점이 있었다.However, the above-described solenoid fuel supply device has a disadvantage in that the manufacturing cost is increased by mounting the block 8 in which the solenoid coil 6 is embedded.

본 고안은 상술한 솔레노이드방식의 연료공급장치에 따른 단점을 해소하도록 안출된 것으로, 형상기억합금을 이용한 연료공급장치의 제공을 목적으로 한다.The present invention has been made to solve the disadvantages of the above-described solenoid fuel supply device, and an object of the present invention is to provide a fuel supply device using a shape memory alloy.

제1도는 종래 솔레노이드방식의 연료공급장치의 개략적인 단면도.1 is a schematic cross-sectional view of a conventional solenoid fuel supply device.

제2도는 본 고안에 따른 연료공급장치의 개략적인 단면도.2 is a schematic cross-sectional view of a fuel supply device according to the present invention.

상기 목적을 달성하게 위한 연료공급장치는, 연료유입구와 배출구사이의 유로를 개폐하도록 상기 유입구와 배출구 사이의 유로에 밸브 스템이 배치되고 헤드는 빈 공간부에 배치되며, 상기 공간부의 상면과 헤드 사이에는 헤드를 하방으로 밀도록 스프링이 배치되고 상기 헤드 저면과 공간부 저면사이에는 전원인가시 헤드를 상방으로 밀도록 하는 형상기억합금의 스프링이 배치되어 구성 된다.In the fuel supply device for achieving the above object, the valve stem is disposed in the flow path between the inlet and the outlet to open and close the flow path between the fuel inlet and the outlet, the head is disposed in the empty space, between the upper surface and the head of the space The spring is arranged to push the head downward, and the spring of the shape memory alloy to push the head upward when the power is applied between the bottom of the head and the bottom of the space portion is arranged.

이하, 첨부도면을 참고하여 본 고안을 구체적으로 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안에 따른 형상기억합금을 이용한 연료공급장치 (10)를 도시하고 있다.2 shows a fuel supply apparatus 10 using a shape memory alloy according to the present invention.

연료공급장치(10)는 연료 유입구(11)와 배출구(12) 사이에 유로(13)를 개폐하도록 밸브(14)가 슬라이드 가능하게 장착된다.The fuel supply device 10 is slidably mounted with a valve 14 to open and close the flow passage 13 between the fuel inlet 11 and the outlet 12.

상기 밸브(14)의 스템(5)은 유로(13)에 배치되고 헤드(16)는 공간부(17)에 배치되어 있다. 상기 공간부(17)에서 헤드(16)저부에는 형상기억합금으로 된 코일(18)이 배치되어 전원인가시 팽창되어 밸브(14)를 상향이동시켜 유로(13)를 개방함으로써 연료가 공급된다.The stem 5 of the valve 14 is arranged in the flow passage 13 and the head 16 in the space 17. In the space portion 17, a head 18 of the head 16 is disposed at the bottom of the shape memory alloy, and is expanded when the power is applied, and the fuel is supplied by opening the flow path 13 by moving the valve 14 upward.

또한, 상기 코일(18)에 전원이 차단되면 수축되는 반면, 헤드 상면에 배치된 스프링(19)의 복원력에 의해 밸브(14)가 하향이동되어 스템(15)에 의해 유로(13)가 폐쇄된다.In addition, while the power is cut off when the coil 18 is cut off, the valve 14 is moved downward by the restoring force of the spring 19 disposed on the upper surface of the coil 18 so that the flow passage 13 is closed by the stem 15. .

본 고안에 따라 형상기억합금의 코일을 사용하여 밸브를 신속하게 개폐시킬 수 있고 솔레노이드를 사용하지 않으므로 제조비용이 저렴한 장점이 있다.According to the present invention it is possible to quickly open and close the valve by using the coil of the shape memory alloy, there is an advantage that the manufacturing cost is low because the solenoid is not used.
