摘要： Embodiments of a combination piston and piston ring to reduce the volume of a crevice defined between the circumferential wall of a cylinder and a portion of the outer wall of a piston within the cylinder, the portion extending down from the top of the piston. The combination piston and piston ring is configured such that pressurized fluid within the cylinder reliably urges a radial face of the piston ring to sealingly engage the circumferential wall of the cylinder, even as the piston reciprocates within the cylinder.

摘要： A seal ring (100) makes contact with a low-pressure-side (L) side wall surface of an annular groove (510) and slides against an inner circumferential surface of a shaft hole of a housing (600) through which a shaft (500) is inserted. The seal ring includes a pair of recessed portions (130) extending in a circumferential direction on an outer surface, wherein a distance between a side surface on one side of a protruding portion (120) that is disposed between the pair of recessed portions (130) and a side surface on another side of the seal ring (100), and a distance between a side surface on another side of the protruding portion (120) and a side surface on one side of the seal ring (100) are set to be shorter than a distance between an inner circumferential surface of the seal ring and an outer circumferential surface of the protruding portion (120).

摘要： The present invention is to provide a sealing device that has a small number of parts as three or less to achieve a more compact sealing device. The sealing device is combined an inner seal ring, an outer seal ring held in an outer circumferential holding groove of the inner seal ring, and a back ring. The outer seal ring satisfies a dimensional size relationship of T>A when T is the radial thickness dimension of the outer seal ring, G is the protrusion gap dimension, R is the radial width dimension of the chamfered sections on the edges of the open side of the seal installation groove, and A is the sum of the protrusion gap dimension G and the radial width dimension R of the chamfered sections on the edges of the open side.

摘要： An improved piston ring for use as an intermediate piston ring in a piston assembly having three or more piston rings is provided. The piston ring includes a piston ring body which extends through an arcuate shape between opposite end faces. The piston ring body has at least one combustion gas guidance feature for allowing a greater flow of combustion gasses to pass the piston ring body when the piston is moving in one direction and for allowing a lesser flow of combustion gasses to pass the piston ring body when the piston is moving in an opposite direction. This allows for the ring gap at the outer diameter of the piston ring to be minimized without creating flutter in another piston ring above the intermediate piston ring during operation of an engine.
摘要翻译：提供了一种用于具有三个或更多个活塞环的活塞组件中的中间活塞环的改进的活塞环。活塞环包括在相对端面之间延伸通过弧形形状的活塞环体。活塞环主体具有至少一个燃烧气体引导特征，用于当活塞沿一个方向移动时允许更大的燃烧气体流通过活塞环体，并且当活塞环体在一个方向上移动时允许更少量的燃烧气体通过活塞环体，活塞正在相反的方向移动。这允许在发动机操作期间在活塞环的外径处的环形间隙最小化，而不会在中间活塞环上方的另一个活塞环中产生颤动。
