摘要:
本发明适用于往复活塞式机械中活塞与缸筒之间密封流体的活塞环,特别是往复活塞式发动机中的气环。本发明的活塞环重叠贴紧,重叠面延环口间隙变化的方向分布,这种重叠使活塞环与缸筒和环槽的贴紧密封面都成为闭合的环形,在以上两闭合环形密封面之间,活塞环与活塞环的重叠面形成密封带,使被密封物质不易通过,这种重叠在环口间隙变化时密封性能不变。其优点是延长了活塞环的使用寿命。
摘要(英):
The present invention is applicable to the piston ring used for sealing fluid between piston and cylinder in reciprocating piston type machine, which is characterized by that the piston rings are tightly overlapped together, and their faying surfaces are distributed along the ring orifice changing direction, so that this piston ring overlapped structure can make the piston rings, cylinder and ring grooves form closed ring sealed surfaces, and the faying surface of the piston rings can be formed into a sealing band so as to can stop the sealed matter from passing through, therefore said invention can retain good sealing property and can prolong the service life of the piston ring.
