Abstract

본 발명은 엔진의 밸브를 지지하는 밸브 스프링이 가변되는 스프링력을 제공할 수 있도록 밸브 스프링의 작동 거리를 조절 할 수 있는 스프링 시트 가동 수단이 포함된 가변 밸브 장치를 제공함으로써, 엔진의 회전수에 따른 적절한 밸브의 동작이 가능하여 엔진의 저속 운전시에는 밸브를 작동시키는 동력을 절감하고 엔진의 고속 운전시에는 밸브 작동의 신뢰성을 확보함으로써 제품의 성능을 향상시킬 수 있다.The present invention provides a variable valve device including a spring seat movable means for adjusting the operating distance of the valve spring to provide a variable spring force for the valve spring for supporting the valve of the engine, thereby reducing the engine speed It is possible to improve the performance of the product by reducing the power to operate the valve at low speed operation of the engine, and ensuring the reliability of valve operation at high speed operation of the engine.
