摘要： A power cylinder assembly for an internal combustion engine is provided. The power cylinder assembly includes a cylinder wall having a channel formed therein and a piston body with a skirt. A piston ring is seated within the channel of the cylinder wall and is sealed against the skirt of the piston body. Specifically, the piston ring has a ring body with an inner face that presents two radially inwardly extending ridges spaced axially from one another by a valley region, and the outer face presents a groove which receives a spring to bias the ridges into sliding engagement with the outer surface of the skirt of the piston body. The ring body also has at least one oil drainage port which extends radially between the valley region of the inner surface and the groove of the outer face for conveying oil from between the ridges into the groove.

摘要： A piston ring assembly consists of an upper ring and a lower ring. Said upper ring and lower ring have a common axis, an outer toward common annular surface, and inner toward common annular surface and mutual contact surfaces. Said two contact surfaces keep to contact with each other in a contact section which has radially an outer end and an inner end. Said tow contact surfaces stretch radially oppositely from said outer end to form a first wedge space, the vertex of which being in the outer end and, with said outer toward common annular surface. The vertex angle is about 1030□. The distance between said outer end and said outer toward common annular surface is greater than the distance between said inner end and said inner toward common annular surface. The present invention also includes a piston wherein said piston ring assembly is being used.

摘要： A sealing apparatus for use in sealing a clearance between a cylinder (38) and a piston (50) without using a lubricating oil. An annular groove (66) is formed in the outer circumferential surface of the piston (50). First and second seal members (68, 70) formed out of a resin material are fitted annularly in an axially piled two-stage in this annular groove (66). A third seal member (72) is fitted annularly on the inner side of these first and second seal members (68, 70). On the inner side of the third seal member (72), a non-endless expander ring (74) adapted to press the first and second seal members (68, 70) against the inner circumferential surface of the cylinder (38) via the third seal member (72) is provided. The first, second and thrid seal members (68, 70, 72) are fitted in the groove (66) so that the clearances between both ends of these seal members are staggered from one another in the circumferential directions thereof and not aligned with one another, and, therefore, the three seal members (68, 70, 72) are arranged in the groove (66) as if a single endless ring were fitted therein.

摘要： An improved piston ring assembly, particularly for a Stirling engine, comprises a piston ring made from a TFE fluorocarbon such as Rulon which is disposed in a piston ring groove and is acted upon by an annular bi-metal element disposed between the groove and the ring. When the engine is cold, the bi-metal element urges the ring outwardly so that a flat radially outer surface of the ring is forced into face-to-face contact with the cylinder wall. When the engine has warmed up, the force of the element of the piston ring is relaxed and the thermal expansion of the piston ring maintains the outer surface of the ring in face-to-face contact with the cylinder wall.
