Abstract: PURPOSE: A filler tube assembly for a vehicle is provided to prevent shake caused by vibration produced during combustion of an engine. CONSTITUTION: A filler tube assembly for a vehicle includes a guide guiding an oil lever gauge to an oil pan; an auxiliary tube(24) supporting a hose(22) of the guide from the outside; and a damper unit disposed between the auxiliary tube and the hose, to produce resistance to fluid(O) flowing according to a change of the sectional area between the hose and the auxiliary tube. In the guide, steel pipes divided around a bent-up portion of a transmission case are disposed, and the hose disposed between the steel pipes is bent correspondingly to the bent-up portion. The damper unit divides the space between the hose and an elastic tube in the circumferential direction, and the damper unit comprises a diaphragm(32) with an orifice hole(31) for flow of fluid. Fluid produces flow resistance while passing through the orifice hole and thus, the external vibration given to a filler tube is absorbed.

Abstract: 본 발명은 차량 엔진의 실린더헤드 오일고임 방지장치에 관한 것으로,
종래에는 실린더헤드측으로의 오일공급량이 과도하여 드레인 한계를 벗어날 경우 오일팬 오일이 부족해서 오일압 떨림 및 저하를 발생시켜 엔진에 치명적 손상(베어링/무빙계 마모)을 일으키게 되고, 또한 실린더헤드에 머무는 오일량이 증가하게 되어 PCV 호스나 브리더 호스를 통해 오일이 외부로 누출될 우려가 많게 되며, 엔진 내부에 오일량 절대 부족으로 엔진 오류를 일으키게 될 우려가 많게 되는 등의 문제가 있었던 바,
PCV 호스와 브리더 호스에 각각 솔레노이드밸브를 설치하고, 오일압 저하/떨림을 측정하는 오일압센서의 감지신호가 전달되는 전자제어유니트(ECU)를 통해 각 호스의 솔레노이드밸브를 작동하도록 한 것을 특징으로 하는 본 발명에 있어서는 오일압 저하 및 떨림이 발생한 경우 오일압센서의 신호가 입력되는 전자제어유니트를 통해 PCV 호스와 브리더 호스에 설치된 솔레노이드밸브를 닫힘 작동시킴으로써 실린더블록 크랭크실과 실린더헤드 사이의 압력차를 해소하여 실린더헤드의 오일을 원활하게 드레인시킬 수 있게 되며, 그에 따라 실린더헤드측의 과도한 오일 고임을 방지할 수 있게 되어 오일압 떨림 및 저하로 유발되는 엔진 베어링계 및 무빙계 오류를 방지할 수 있게 되는 등의 효과를 얻을 수 있게 된다.
