The elastic piece 4 includes a holding portion 41 fixed to the valve cover 2, an extension portion 42 further obliquely extending from the holding portion 41, and an end portion 43 bent downward from the end of the extension portion 42. The connection between the extension 42 and the end 43 forms an arc surface 44 for mating with the support 5.

使用时，发动机的排气自筒状部123进入开口122中，并与阀盖2的凹陷部211产生作用力。当排气压力大于弹片4对阀盖2的压力时，所述阀盖2被排气推开。在此过程中，所述阀盖2绕所述轴22转动，同时所述弹片4的弧形表面44沿着所述支撑部53滑动。由于所述V形面531呈V形，当所述弹片4的变形量越大时，其与所述面531的接触面积越大，二者所产生的摩擦力也就越大，从而需要更大的排气压力才能将阀盖2的开度进一步增大。When in use, the exhaust from the engine enters the opening 122 from the cylindrical portion 123 and generates a force with the recessed portion 211 of the valve cover 2. When the exhaust pressure is greater than the pressure of the elastic piece 4 on the valve cover 2, the valve cover 2 is pushed open by the exhaust. During this process, the valve cover 2 rotates around the shaft 22 while the arc-shaped surface 44 of the elastic piece 4 slides along the supporting portion 53. Since the V-shaped surface 531 is V-shaped, when the amount of deformation of the elastic sheet 4 is greater, the contact area between the elastic piece 4 and the surface 531 is larger, and the friction force generated by the two is also greater, thus requiring greater The exhaust pressure can increase the opening of the valve cover 2 further.
相较于现有技术，本发明通过将轴22安装在支架5与安装部11之间，通过简单的机械装配就能实现。另外，弹片4与阀盖2相接触，通过弹片4来实现阀盖2打开或者关闭的功能，省略了扭簧，降低了成本。Compared with the prior art, the present invention can be realized by simple mechanical assembly by installing the shaft 22 between the bracket 5 and the mounting portion 11. In addition, the elastic piece 4 is in contact with the valve cover 2, and the opening or closing function of the valve cover 2 is realized by the elastic piece 4. The torsion spring is omitted, and the cost is reduced.
