内燃机进排气阀控制装置
摘要：
本发明涉及一种用于控制内燃机进排气阀的装置，包括凸轮(3)和与凸轮(3)相配合的顶杆机构，所述顶杆机构包括一个滚轮(1)，滚轮(1)具有与凸轮(3)共轭运动的共轭曲面。由于根据本发明的用于控制内燃机进排气阀的装置中采用了凸轮工作表面与滚轮工作表面相互为共轭曲面，所以是通过凸轮和滚轮相互接触的工作表面处至两者的回转轴线之间距离的变化之和对内燃机进排气阀的开启度进行调节。与现有技术中仅仅通过凸轮上不同位置处工作表面上一点至其回转轴线的距离的变化实现调节相比，根据本发明的调节范围更大，更灵活。
摘要（英）：

The invention relates to a device for controlling an air inlet valve and an air outlet valve of an internal combustion engine. The device comprises a cam (3) and a push rod mechanism matched with the cam (3), wherein the push rod mechanism comprises an idler wheel (1); and the idler wheel (1) is provided with a conjugate surface in conjugate movement with the cam (3). In the device controlling the air inlet valve and the air outlet valve of the internal combustion engine, the working surface of the cam and the working surface of the idler wheel are mutually conjugate surfaces, so the device can adjust the opening degree of the air inlet valve and the air outlet valve of the internal combustion engine according to the change sum of the distance from the contacting part of the working surfaces of the cam and the idler wheel to the rotary axis of the cam and the idler wheel. Compared with the prior art that the adjustment is realized according to the change of the distance from one point, at different positions, on the working surface of the cam to the rotary axis of the cam, the device has a wider and more flexible adjusting range.
