摘要： A piston assembly including a piston body and a piston ring is provided. The piston body has a skirt, a portion of which extends circumferentially continuously and has a skirt diameter. The piston ring has a ring body which extends through at least one revolution in a generally helical shape when in a relaxed condition. The ring body also has an inner face, and when in the relaxed condition, the inner face presents a ring diameter which is less than the skirt diameter. The ring body circumferentially surrounds the skirt of the piston body, thereby causing the inner face to be biased into engagement with the outer surface of the circumferentially continuous portion of the skirt of the piston body to establish a dynamic seal between the ring body and the piston body.

摘要： A piston ring for sealing a cylinder wall to a piston body is provided. The piston ring includes a ring body that extends about an axis and has inner and outer faces. The inner face presents a pair of ridges that extend in a radially inward direction, and the outer face presents a groove. A spring of an elastomeric material substantially circumferentially surrounds the ring body and is seated in the groove on the inner face. The spring biases the ring body in the radially inward direction to seal the ridges against the piston body. The ring body also has at least one oil drainage port which extends at an angle relative to the radially inward direction from the inner face to a location on the outer face on one axial side of the spring for conveying oil out of a space between the ridges.

摘要： A piston assembly comprises a piston body, a connecting rod, and a wrist pin. The piston body includes a pair of first cross bores presenting a piston sliding surface. The connecting rod includes a second cross bore presenting a rod sliding surface which is axially aligned with the first cross bores of the piston body. A wrist pin is disposed in the aligned cross bores and couples the piston body to the connecting rod. The wrist pin also presents a pin sliding surface facing the rod sliding surface and the piston sliding surfaces. A coating is applied to at least one of the sliding surfaces, such as by dipping, brushing, atomizing, spraying, printing, or screen printing. The coating includes a polymer matrix, such as polyamide imide (PAI), and hard particles, such as Fei03, disposed throughout the polymer matrix. The hard particles have a hardness of at least 600 HV/0.5.

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.
