本发明是用于内燃机(或类似机械)活塞环内面的胀簧,它安装在活塞环槽内,可增加活塞环与周围缸壁的接触压力。 传统的活塞环只采用单层波纹形胀簧。为增加胀簧的表面比压,可以增加胀簧的厚度或缩小波纹的间距。但这两种方法都使胀簧的弹簧常数增加了,结果就达不到为保证比压所要求的“挠度容差”。此外,从制造上看,波纹形的单层胀簧,波峰高度总会有偏差,如果制
The present invention is an expansive spring for use on the inner surface of a piston ring of an internal combustion engine (or similar) which is installed in a piston ring groove to increase the contact pressure of the piston ring with the surrounding cylinder wall. The traditional piston ring only uses single-layer corrugated bulging spring. In order to increase the surface pressure of the expander spring, the thickness of the expander spring may be increased or the spacing of the ripple may be reduced. However, both of these methods increase the spring constant of the expander spring and consequently fail to achieve the “deflection tolerance” required to maintain the specific pressure. In addition, from the manufacturing point of view, the corrugated single expansion spring, the peak height there will always be deviations, if the system
