摘要： A piston ring assembly including a pair of rails engageable with a cylinder wall and a spacer and expander member for holding and expanding the rails. The spacer and expander member has a corrugated base and arms extending alternately upwardly and downwardly from lower and upper crowns of the corrugated base, which arms are inclined radially outwardly to provide an improved resilient spring-like action to the rails supported on the crowns.

摘要： A rotary piston internal combustion engine has a rotor journalled on an eccentric portion of an engine shaft. A sealing arrangement comprises a first radially extending annular face connected to the engine shaft, a disc connected to the rotor and having a second radially extending annular face, and a sealing ring disposed between the first and second faces. A spring biases the sealing ring to maintain sealing contact of the sealing ring with one of the first and second faces. An O-ring is disposed between the sealing ring and that one of the rotor and engine shaft which is in rotatable unison with the other one of the first and second faces.

摘要： The annular expander of a piston ring assembly with vertically extending notches each of which is formed on either side of a plurality of circumferentially spaced upstanding tabs projecting from the top and bottom edges of the expander. The tabs, which form the abutments for the inner peripheral edges of upper and lower annular side rails, the outer peripheral edges of which are in sliding contact with a cylinder wall, undergo elastic deformation made possible by the notches when the corresponding side rails are subjected to a strong force received from the cylinder wall owing to piston wobble during reciprocation. The elastic deformation of the tabs assures that the side rails will remain in contact with the cylinder wall at all times during the reciprocation of the piston.
摘要翻译：活塞环组件的环形膨胀器具有垂直延伸的凹口，每个凹槽形成在从膨胀机的顶部和底部边缘突出的多个周向间隔开的多个突出的突出部的任一侧上。形成用于其外周边缘与气缸壁滑动接触的上下环形侧轨的内周边缘的突出部，当相应的侧轨受到影响时，会产生由凹口产生的弹性变形在往复运动期间由于活塞摆动而从缸壁接收的强力。突片的弹性变形确保了在活塞往复运动的过程中，侧轨将始终与气缸壁保持接触。
