导向密封面带环槽的阀杆
摘要：
本发明公开了属于发动机零部件范围的一种导向密封面带环槽的阀杆。在阀杆的导向密封面上开有n道环槽。本发明与现有技术相比，可以在相同的配合间隙和密封压力下，大幅度降低燃油泄漏率和减小阀杆所受侧向力，确保阀杆运动的灵活性，防止阀杆卡死。
摘要（英）：

The valve handle with guide sealing surface and ring grooves belongs to engine components. N ring grooves are set at the guide sealing surface of the valve handle. Compared with existing technology, it can dramatically reduce fuel leakage rate and side force of the small valve handle; ensure flexible movement of the valve handle to prevent stoppage of the valve handle with the same fitting gap and sealing pressure.
