[Solving Means] A seal ring according to a first aspect of the present invention includes a center axis, an outer peripheral surface, an inner peripheral surface, a side surface, and a groove. The center axis is a rotation center. The outer peripheral surface is an outward cylindrical surface whose center is positioned at the central axis. The inner peripheral surface is an inward cylindrical surface disposed between the center axis and the outer peripheral surface whose center is positioned at the central axis. The side surface connects the outer peripheral surface and the inner peripheral surface. The groove is formed in a dented groove from the side surface, extends along a radial direction spaced from the outer peripheral surface, has a first end connected to the inner peripheral surface and a second end at an opposite side of the first end, and returns oil entered from the first end to an inner peripheral surface side via the second end.

    摘要： Provided is a seal ring capable of preventing an increase in a rotational torque even if a sliding surface wears out as the sliding surface is used. A seal ring (100) is attached to an annular groove (210) provided on an outer periphery of a shaft (200), and slides on a lateral wall surface (211) of the annular groove (210) on a lower pressure side. The seal ring (100) includes: a dynamic pressure generation groove (120) that generates dynamic pressure with sealed fluid introduced thereinto, the dynamic pressure generation groove (120) being provided in a sliding region X of a lateral surface (111) thereof on the lower pressure side in which the lateral surface (111) slides on the lateral wall surface (211); and a introduction hole (130) that has an opening (131) at a position away from the lateral surface (111) of an inner peripheral surface (112) of the seal ring (100) by a distance Y, communicates with the dynamic pressure generation groove (120), and introduces the sealed fluid into the dynamic pressure generation groove (120).

    摘要： The present invention provides a seal ring, for a variable valve timing system, which is resistant to breakage when the seal ring is expanded at a seal ring mounting time even in a case where the seal ring is thick and allowed to have a complicated configuration by performing injection molding and achieve a small oil leak, a low degree of friction, and improved wear resistance. In the variable valve timing system having a camshaft (5) for driving an intake valve of an internal combustion engine and an exhaust valve thereof, an inner rotational body (3) fixed to the camshaft (5), an outer rotational body (4) making a rotational motion relative to the inner rotational body (3) by supply of hydraulic oil at a time of altering opening and closing timings of the intake valve and the exhaust valve, and a shaft body (2) mounted on an inner circumference of the inner rotational body (3) concentrically with the inner rotational body (3) and the outer rotational body (4), a seal ring (1) for the variable valve timing system seals annular passages (8b, 9b), formed between the inner rotational body (3) and the shaft body (2a), which serve as an oil passage of the hydraulic oil. The seal ring (1) is formed by molding a polyphenylene sulfide resin composition containing polyphenylene sulfide resin as a main component thereof and an elastomer.

    摘要： An intershaft seal assembly comprises an annular seal ring disposed between a pair of annular runners connected to a hollow outer rotating shaft, and a surface of a co-axial inner rotating shaft. The centrifugal force resulting from rotation of the hollow outer rotating shaft effects engagement of the annular seal ring with the surface of the co-axial inner rotating shaft. The surface may be a radially-inward-facing surface of a retaining arm connected to the co-axial inner rotating shaft.

    摘要： An object is to provide a seal structure capable of reducing abrasion of a seal ring without increasing the number of components and of minimizing generation of abrasion powder. A seal structure to seal clearance between an outer peripheral surface 8a of a rotary shaft 8 and an inner peripheral surface 6a of a bearing housing 6 includes: a first seal groove 22A formed on the outer peripheral surface 8a of the rotary shaft 8; a second seal groove 22B disposed between the first seal groove and the impeller; a first seal ring 26 to be mounted to the first seal groove; and a second seal ring 28 to be mounted to the second seal groove. The first seal ring 26 includes a first-seal body portion 26A mounted to the first seal groove, and a first-seal protruding portion 26B protruding from the first-seal body portion toward the second seal ring 28, and being configured to be in contact with the second seal ring contacting a bearing-side wall surface 22Ba of the second seal groove, in a state in which the first-seal body portion is in contact with a bearing-side wall surface 22Aa of the first seal groove.
