Piston and steam cylinder assembly

一种活塞和汽缸组件

Abstract

本实用新型公开了一种活塞和汽缸组件。在一些二冲程发动机中,静止环被设置在汽缸壁中的圆周凹槽中。然而,安装这种静止环且同时保持窄的间隙以最小化通过该间隙的气流是有挑战性的。所公开的一种用于内燃机的环系统,其包括具有凹角的L形开口环和邻近凹角与L形环嵌套的具有凸四边形横截面的嵌套开口环。两个环被固定,以致开口环的两个间隙不能对准。或者,在其它实施例中,两个环被允许在预定角度的范围内相对于彼此旋转。
The utility model discloses a piston and a steam cylinder assembly. In some two-stroke engines, a static ring is arranged in a circumferential groove in a steam cylinder wall, but when the static ring is installed, maintenance of a narrow gap and minimization of airflow passing the gap are challenging. A ring system for an internal combustion engine comprises an L-shaped snap ring with a concave angle and a nest snap ring which is adjacent to the concave angle, nested with the L-shaped ring, and provided with a convex quadrilateral cross section. The two rings are fixed, so that two gaps of the snap rings cannot be aligned with each other, or in other embodiments, the two rings are allowed to rotate relative to each other within a preset angle range.
