    摘要： A shaft seal configured to seal an oil space from a fuel space of an injection pump for an internal combustion engine coaxially and sealingly surrounds a rod configured to oscillate axially with respect to the shaft seal. The shaft seal is configured to seat in a bore of a housing of the injection pump in a sealing manner, and the shaft seal includes a first seal element to which a second seal element is axially connected. The first seal element and the second seal element are configured as substantially hollow cylinders and may be formed from different materials.

    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： A sealing structure allows for formation of a side lip, as well as a labyrinth structure between an oil seal and a torsional vibration damper, even when a reinforcing ring has a short inward flange part. The sealing body 120 includes a side lip 124 extending from near a distal end of an inward flange part 112 radially inward and further toward an air side (A) than a dust lip 122 to a position not as far as the outer circumferential surface of a tubular part 210. An annular member 250 is further provided, which is fixed to the outer circumferential surface of the tubular part 210 further on the air side (A) than the side lip 124 and covering an outer circumferential surface of the side lip 124 such that there is a gap between the annular member 250 itself and the outer circumferential surface of the side lip 124.

    摘要： A piston assembly for a torque converter is provided. The piston assembly includes a seal assembly including an inner ring configured for fixing to an outer circumferential surface of a transmission input shaft. The seal assembly also includes an outer ring on an outer circumferential surface of the inner ring. The piston assembly also includes a lock-up clutch piston including a radially inner end engaging the seal assembly. A method of forming a piston assembly for a torque converter is also provided. The method includes providing an outer ring on an outer circumferential surface of an inner ring to form a seal assembly configured for fixing to an outer circumferential surface of a transmission input shaft and connecting the seal assembly to a radially inner end of a lock-up clutch piston.
