도면부호 1은 레조네이터를 나타내는 것으로, 상기 레조네이터(1)는 서지탱크(2)와 연통하도록 장착되어 있다.Reference numeral 1 denotes a resonator, and the resonator 1 is mounted to communicate with the surge tank 2.

상기 레조네이터(1)와 서지탱크(2)를 연결하는 연결부(3)에는 원판상으로 된 고정밸브(4)와 회전밸브(5)가 설치되는데, 상기 고정밸브(4)는 레조네이터(1)측에 위치하여 고정 설치되는 한편, 상기 회전밸브(5)는 서지탱크(2)측에 위치하여 회전가능하게 설치되어 있다.In the connecting portion 3 connecting the resonator 1 and the surge tank 2, a fixed valve 4 and a rotary valve 5 having a disc shape are installed, and the fixed valve 4 is provided on the resonator 1 side. The rotary valve 5 is rotatably positioned at the side of the surge tank 2 while being fixedly installed.

또한 상기 고정밸브(4)와 회전밸브(5) 각각에는 고정공(41)과 조절공(51)이 서로 어긋난 방향을 향해 편심된 상태로 형성되어 있다.In addition, each of the fixed valve 4 and the rotary valve 5 is formed in a state in which the fixing hole 41 and the adjusting hole 51 are eccentric toward each other.

상기 회전밸브(5)의 일측에는 연결부(3)외부로 돌출된 고리(52)가 형성되어 있으며, 상기 고리(52)는 서지탱크(2)의 흡기부측에 장착된 스로틀 밸브(61)를 회전작동시키는 스로틀 밸브레버(6)에 연결선(7)으로 연결되어 있다.One side of the rotary valve (5) is formed with a ring 52 protruding out of the connecting portion (3), the ring 52 rotates the throttle valve (61) mounted on the intake side of the surge tank (2) It is connected to the throttle valve lever 6 to be operated by a connecting line 7.

상기 레조네이터(1)의 일측에는 용적가변날개(8)가 회전가능하게 설치되는데, 상기 용적가변날개(8)는 레조네이터(1) 상단에 장착된 모터(9)에 의하여 회전작동하여 레조네이터(1)의 공명실 용량을 증감 가변시킬 수 있도록 구성되어 있다.One side of the resonator (1) is installed rotatably the volume variable wing (8), the volume variable wing (8) is rotated by the motor (9) mounted on the top of the resonator (1) to the resonator (1) It is configured to increase or decrease the resonance chamber capacity of the.

이와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.

엔진의 저(低)rpm 영역에서는 회전밸브(5)의 조절공(51)과 고정밸브(4)의 고정공(41) 각각은 서로 반대방향을 향해 편심된 상태로 조정되어 레조네이터(1)와 서지탱크(2)를 연통시키는 연결부(3)의 목단면적이 최소상태가 되며(도 4의 실선부분 참조), 또한 레조네이터(1)의 일측에 장착되어 있는 용적가변날개(8)는 도 5의 실선부분 도시예와 같이 레조네이터(1)의 공명실 용량을 축소시킨 상태로 작동되어 있다.In the low rpm region of the engine, each of the adjusting hole 51 of the rotary valve 5 and the fixing hole 41 of the fixed valve 4 is adjusted so as to be eccentrically opposite to each other so that the resonator 1 and The neck end area of the connecting portion 3 communicating the surge tank 2 is minimized (refer to the solid line in FIG. 4), and the volume-variable wing 8 mounted on one side of the resonator 1 is shown in FIG. 5. The solid line portion is operated with the resonance chamber capacity of the resonator 1 reduced as shown in the example.

상기와 같이 엔진이 저rpm 영역으로 구동할 때에는 스로틀 밸브(61)의 개방각도도 작은 상태이어서 이때의 흡기량도 적으므로 연결부(3)의 목단면적과 레조네이터(1)의 공명실 용량이 축소조정된 상태이므로 가장 효율적인 공명효과를 거둘 수 있게 된다.As described above, when the engine is driven in the low rpm region, the opening angle of the throttle valve 61 is also small and the intake amount is small. Therefore, the neck area of the connecting portion 3 and the resonance chamber capacity of the resonator 1 are reduced. Because of the state, the most efficient resonance effect can be achieved.

엔진이 저rpm 영역에서 고rpm 영역으로의 구동 즉, 운전자가 액셀페달을 가속함에 따라 스로틀 밸브레버(6)가 ECU로부터 신호를 받아 회전하여 스로틀 밸브(61)의 개방각도를 크게 하여 흡기량을 증가시키게 되는데, 이때 상기 스로틀 밸브레버(6)의 회전작동에 따라 연결선(7)이 회전밸브(5)를 회전시키게 되므로서 조절공(51)과 고정공(41)의 단면적이 점차로 커지게 되며(도 4의 가상선부분 참조), 또한 모터(9)도 ECU로부터 신호를 받아 구동하여 용적가변날개(8)를 회전시켜 레조네이터(1)의 공명실 용량을 증가시키게 되므로(도 5의 가상선부분 참조) 흡기량의 증대에 따른 연결부(3)의 단면적이 커짐과 동시 레조네이터(1)의 공명실 용량이 증대되므로서 효율적인 공명효과를 거둘 수 있게 되는 것이다.As the engine drives from the low rpm region to the high rpm region, that is, as the driver accelerates the accelerator pedal, the throttle valve lever 6 receives a signal from the ECU and rotates to increase the opening angle of the throttle valve 61 to increase the intake air amount. In this case, as the connecting line 7 rotates the rotary valve 5 according to the rotation operation of the throttle valve lever 6, the cross-sectional area of the adjusting hole 51 and the fixing hole 41 is gradually increased ( In addition, since the motor 9 also receives a signal from the ECU and is driven to rotate the volume variable blade 8, the resonance chamber capacity of the resonator 1 is increased (see the virtual line portion of FIG. 5). Ref.) As the cross-sectional area of the connecting portion 3 increases with the increase of the intake air amount, and the resonance chamber capacity of the resonator 1 increases, the effective resonance effect can be achieved.

상기와 같은 본 발명에 의하면 엔진의 저rpm 영역에서부터 고rpm 영역에 이름에 따라 슬로틀 밸브레버에 연결된 회전밸브가 회전작동하여 연결부의 목단면적을 가감시킬 수 있고 이와 동시에 모터가 구동하여 용적가변날개를 회전시켜 레조네이터의 공명실 용량을 가감시킬 수 있는 바, 이에 따라 엔진의 전 rpm 영역에 대하여 효율적인 공명효과를 거둘 수 있도록 레조네이터의 제원을 가변시킬 수 있어 흡기효율의 증대와 함께 엔진성능을 개선시키는 효과를 얻을 수 있는 것이다.According to the present invention as described above, the rotary valve connected to the throttle valve lever is rotated according to the name from the low rpm region to the high rpm region of the engine to increase or decrease the neck area of the connecting portion, and at the same time, the motor is driven to change the volume of the wing. The resonance chamber capacity of the resonator can be reduced by rotating the bar. Therefore, the specifications of the resonator can be varied to achieve an effective resonance effect for the entire rpm range of the engine. Thus, the engine performance is improved while increasing the intake efficiency. You can get the effect.
