Claims (2)

흡,배기밸브를 개폐하는 캠을 다수개 보유하는 캠축에 있어서, 상기한 캠축(2)의 후단부에 헬리컬 스플라인 축(5)을 일체로 형성하여 플랜지(8)를 갖는 스플라인 허브(6)와 결합하고, 실린더 헤드(1)에 실린더(10)를 형성하여 그 내측에 피스톤(11)을 슬라이드 가능하게 설치함과 아울러 이 피스톤(11)의 선단에 요크(9)를 설치하여 상기한 플랜지(8)를 회전가능하게 설치하고, 실린더(10)의 후단부를 ECU의 출력 신호에 의해 개페하는 솔레노이드 밸브(12)가 설치된 오일통로(13)와 연결하여 솔레노이드 밸브(12)가 개방상태에서 실린더(10)내로 오일압력이 작용토록 함으로서 피스톤(11)의 전진으로 스플라인 허브(6)가 직선이동하여 헬리컬 스플라인 축(5)을 회전시켜 캠축(2)을 일정각도 만큼 회전시키도록 구성한 것을 특징으로 하는 자동차 엔진의 흡, 배기밸브 가변 개폐장치.In a camshaft having a plurality of cams for opening and closing the intake and exhaust valves, a spline hub 6 having a flange 8 by integrally forming a helical spline shaft 5 at the rear end of the camshaft 2; And a cylinder (10) in the cylinder head (1) to slidably mount the piston (11) inside thereof, and a yoke (9) at the tip of the piston (11) to provide the flange ( 8) is rotatably installed, and the rear end of the cylinder 10 is connected to an oil passage 13 provided with a solenoid valve 12 which opens by an output signal from the ECU, so that the solenoid valve 12 is opened in an open state. 10) the spline hub 6 moves linearly with the advancement of the piston 11 as the oil pressure acts to rotate the helical spline shaft 5 so as to rotate the cam shaft 2 by a predetermined angle. Variable intake and exhaust valves of automobile engines Switchgear. 제1항에 있어서, 스플라인 축(5)에 설치된 플랜지(8)는 피스톤(11)내측으로 공회전 가능하게 설치됨을 특징으로 하는 자동차 엔진의 흡, 배기밸브 가변 개폐장치.2. A variable opening and closing device for an intake and exhaust valve of an automobile engine according to claim 1, wherein the flange (8) provided on the spline shaft (5) is installed to be idling inwardly of the piston (11). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
